Home

Renovations are often about shiny new kitchens and beautiful bathrooms. But there’s an invisible factor that impacts your family’s health and comfort every single day: the air you breathe at home. Indoor Air Quality (IAQ) isn’t just another checkbox – it’s arguably the most crucial upgrade you can make during a remodel. Here’s why homeowners in the U.S. and Canada should put IAQ at the top of their renovation priority list.

“The quality of the air inside our homes plays an important role in how we feel day by day.” — Mike Holmes, professional contractor (makeitright.ca)

The Invisible Hazard Lurking in Your Home’s Air

You might be surprised to learn that indoor air can be far more polluted than outdoor air. According to the U.S. EPA, pollutant levels inside homes are often 2 to 5 times higher than outdoor levels (carrollcountyohio.us). Modern homes are built tighter for energy efficiency, which means any contaminants can get trapped and concentrate indoors. We also spend roughly 90% of our time inside, so exposure adds up. Common indoor pollutants include:

Volatile Organic Compounds (VOCs): These are chemicals that easily evaporate at room temperature. They come from paints, varnishes, adhesives, cleaners, and even new furniture or flooring. For example, pressed-wood cabinets and furniture often off-gas formaldehyde, a VOC that Health Canada considers so harmful it has set strict residential exposure limits. That “new carpet” or “fresh paint” smell? It’s actually VOCs being released into your air.
Particulates and Dust: Renovation activities like sanding drywall or demolishing old materials create fine dust. If not properly contained, these particles can linger and be inhaled. Even daily living generates dust, pet dander, and pollen that circulate through the house.
Biological Allergens: Mold spores and dust mites thrive in poorly ventilated, damp environments. Disturbing an old wall during a remodel could release hidden mold. If moisture isn’t controlled (for instance, from leaks or high humidity), mold can take hold and trigger allergies or asthma.
Combustion Byproducts: Fuel-burning appliances (gas stoves, furnaces, fireplaces) and tobacco smoke release pollutants like carbon monoxide (CO), nitrogen dioxide (NO₂), and particulate matter. Without adequate ventilation, these can build up indoors. Even candles and incense contribute fine particles to your indoor air.

It’s clear that many sources contribute to poor IAQ. Remodeling can exacerbate this by introducing new materials that “off-gas” pollutants. The EPA notes that activities like painting, installing carpet, or using solvents can release VOCs for days or weeks, so extra ventilation is recommended during and for at least 72 hours after installation (epa.govepa.gov). In other words, every renovation choice – from the paint on your walls to the sealant under your flooring – can affect your home’s air.

How Poor IAQ Makes You Sick and Tired

Breathing unhealthy air can take a real toll on your well-being. In the short term, indoor pollutants often cause irritation of the eyes, nose, and throat, as well as headaches, dizziness, and fatigue (epa.gov). If you’ve ever felt drowsy or gotten a headache in a stuffy, freshly painted room, you’ve experienced these effects firsthand. High levels of CO₂ (from lack of fresh air) can make you groggy and less productive. In fact, a Harvard study in 2021 found that lower ventilation rates (high CO₂) and increased fine particles were linked to slower response times and reduced cognitive function in adults (hsph.harvard.edu). In other words, stale air can literally cloud your thinking and sap your energy.

Over the long term, the health risks amplify. Chronic exposure to indoor pollutants is linked to respiratory diseases, heart disease, and even cancer (epa.gov). A well-known example is radon gas – a radioactive gas that seeps from the ground – which is the second leading cause of lung cancer after smoking (epa.gov). Formaldehyde and benzene (common VOCs from building materials and furnishings) are carcinogenic as well. Repeated exposure to mold or dust mite allergens can lead to or worsen asthma and allergies, especially in children.

Perhaps most striking is the estimate from health experts that about 50% of all illnesses are caused or aggravated by polluted indoor air (carrollcountyohio.us). Think about that – the very air in our homes could be contributing to half of our health issues, from allergies and asthma attacks to frequent colds and bronchitis. Children and elderly people, who often spend even more time indoors, are particularly vulnerable. Poor IAQ has also been associated with what’s known as “sick building syndrome”, where occupants experience symptoms like fatigue, nausea, or respiratory irritation that improve when they leave the home. Over time, a home with bad air can literally make your family sicker and more tired than it should be.

“50% of all illnesses are either caused or aggravated by polluted indoor air.” — American College of Allergy, Asthma & Immunology (carrollcountyohio.us)

The flip side of this coin is good news: improving your indoor air quality can lead to noticeable health improvements. People often report sleeping better, having more energy, and suffering fewer allergy symptoms once they address IAQ issues. Let’s look at some specific benefits of making cleaner air a priority.

The Health, Comfort, and Financial Benefits of Clean Air

Focusing on IAQ in your renovation isn’t just about avoiding problems – it actively creates positives for your home and wallet. Here are the key benefits you can expect when you breathe easier:

Healthier Family: Cleaner air means fewer irritants and germs circulating. Your family may experience fewer illnesses and allergy flares once VOCs, mold, and dust are under control. By filtering out pollutants and bringing in fresh air, you reduce the burden on your lungs and immune system. Over years, this can lower risks of serious conditions tied to air quality. (For example, eliminating radon exposure can significantly cut lung cancer risk.) Simply put, a healthy home environment supports healthier inhabitants.
Greater Comfort and Well-Being: Ever notice how a musty, stale room makes you uneasy, while a fresh, airy space feels invigorating? Good IAQ improves daily comfort. Proper ventilation removes stuffiness and odors, regulating humidity so the air “feels” better – not too dry in winter, not too humid in summer. This can also protect your home from damage: controlling humidity prevents mold growth and rot in your walls (a hidden danger Mike Holmes warns about (makeitright.ca)). When your home smells clean and the air is clear, it’s a more pleasant place to live. Some homeowners even find that with higher IAQ, they sleep better at night and wake up more refreshed.
Energy Efficiency & Lower Bills: Surprisingly, investing in air quality can save you money in the long run. Modern ventilation systems like heat recovery ventilators reclaim warmth from outgoing air, so you get fresh air without wasting energy. When running optimally, an HRV can recover up to 80% of the heat from the air being exhausted, dramatically cutting the cost of heating that replacement air (makeitright.ca). This means you don’t have to choose between fresh air and high energy bills – you can have both. By maintaining good IAQ, you also keep HVAC systems running efficiently (clean filters and ducts reduce strain on your furnace/AC). All of this can translate into lower utility bills year after year.
Avoiding Costly Problems: Preventative IAQ improvements are far cheaper than reacting to health or home repairs later. Consider mold: fixing a mold infestation or repairing rot in wooden framing can cost thousands of dollars, not to mention the temporary relocation and hassle during remediation. By managing moisture and ventilating properly now, you sidestep those nightmare scenarios. Similarly, an $30–$50 carbon monoxide monitor or a $200–$300 air quality monitor is a tiny investment compared to the medical costs of treating carbon monoxide poisoning or chronic asthma. Good air can even mean fewer doctor visits and medications, saving you money and stress over time.
Boosted Home Value and Marketability: There’s a growing awareness of healthy homes in the real estate market. Homebuyers (especially families) are increasingly looking for features like ventilation systems, whole-house air purifiers, and low-VOC materials. A home that “breathes” well and smells fresh gives a great first impression. If your renovation includes IAQ upgrades – say, you installed an ERV system or used all non-toxic finishes – be sure to highlight that if you ever sell. It can set your property apart. While the exact ROI is hard to quantify, an IAQ-focused renovation aligns with green building trends and could make your home more attractive to health-conscious buyers. Essentially, you’re future-proofing your home for a market that values wellness.

In short, improving IAQ pays off in multiple ways. You get a healthier, happier family and you protect the long-term value of your home. Next, let’s talk about how to actually achieve better indoor air quality, starting with the materials you choose in your renovation.

Renovation Materials Matter: Avoiding the “Toxic Home” Syndrome

When renovating, it’s easy to get caught up in countertops and color schemes. But the materials and products you use can have a huge impact on IAQ. Many conventional building materials and home products quietly emit pollutants, especially when new. Let’s break down some common culprits and how to make healthier choices:

Paints, Stains, and Finishes: Standard paints, wood stains, and polyurethanes often contain high levels of VOCs (like benzene, toluene, and formaldehyde). These chemicals can off-gas for weeks, causing that “paint smell” along with headaches and irritation. The solution? Opt for low-VOC or zero-VOC paints and finishes. These products are now widely available and perform just as well. If you’re painting or varnishing during a reno, ventilate thoroughly — use fans and open windows (if outdoor air quality is good) to clear out fumes (canada.ca). Pro tip: look for products certified by GreenGuard or labeled “low/zero VOC” – it means they’ve been tested for indoor emissions.
Adhesives, Caulks, and Sealants: That new flooring or backsplash might require adhesives or caulk, which can be another source of VOCs and even hazardous solvents. Choose non-toxic, low odor adhesives and caulks whenever possible. Many brands now offer “low VOC” construction adhesives and siliconized caulks that don’t off-gas as much. Also, be mindful of spray foams or aerosol products; some release isocyanates or other nasties. Always use them with proper ventilation and personal protection, or find healthier alternatives (like water-based expanding foams).
Flooring and Cabinets: Vinyl flooring, carpet, engineered wood, and pressed wood products (like MDF, particleboard cabinetry, or laminate furniture) can emit chemicals. Formaldehyde, for example, often comes from the resins in pressed wood and is a known irritant and carcinogen. When upgrading floors, consider natural materials (like solid wood, tile, or linoleum) and check if products are CARB2 compliant (meaning they meet strict formaldehyde emission standards). If you install new carpet, look for “low VOC” carpets and ventilate well afterward – carpet and the adhesives used can off-gas 4-PC and other odorous chemicals. Similarly, pre-finished solid wood or plywood cabinets can be preferable to particleboard. Some cabinetry now advertises no-added-formaldehyde construction.
Insulation and Wall Materials: Certain foam insulations and older insulation materials can release compounds. For instance, some spray polyurethane foams can off-gas when curing, and older urea-formaldehyde foams were notorious for off-gassing formaldehyde (not used much now). Fiberglass itself isn’t a VOC source but can release small fibers if not sealed. A renovation is a chance to improve insulation, so consider formaldehyde-free insulation (like formaldehyde-free fiberglass or natural wool/cotton insulations). These improve energy efficiency and air quality by avoiding added chemicals. Also, always repair water-damaged drywall – wet drywall breeds mold behind the scenes.
Cleaning and Coating During Reno: Construction dust is not just messy – it’s an inhalation hazard. Fine particles from drywall, wood, or concrete can lodge in your lungs. Contractors should follow dust control practices (like plastic barriers and negative air machines). As a homeowner, you’ll want to do a deep clean after construction. Use a HEPA-filter vacuum to trap fine dust and wipe surfaces with a damp cloth (dry dusting just redistributes particles). And be cautious with construction-site cleaners or paint strippers – many are high-VOC. Use safer alternatives or ensure good ventilation and respiratory protection when strong chemicals are in use (epa.gov).
Beware of Legacy Hazards: If your home was built before the 1980s, test for lead and asbestos before any demolition. Sanding old lead paint or tearing out asbestos insulation/tile can release highly dangerous particles. The EPA advises treating any pre-1978 paint as lead until proven otherwise (epa.gov). Hire certified professionals for removal or contain the area completely if such materials are present. It’s worth the extra precaution – these toxins can cause serious long-term health issues if inhaled. Similarly, watch out for mold in older damp areas; proper remediation (usually with professional help) is necessary if a renovation uncovers significant mold colonies.

In summary, think of your renovation materials as ingredients in your home’s “air soup.” If you put in toxic ingredients, you’ll breathe them. If you choose healthy, low-emission materials, you’ll breathe easier. Always read labels and look for health or environmental certifications. And remember: even with healthier materials, fresh air flow during installation is key to dissipating any initial off-gassing (epa.gov).

Ventilation: Giving Your Home the Breath of Life

Even with the cleanest materials, a home needs proper ventilation to maintain healthy air. Modern homes, especially new builds or well-insulated renovations, are much more airtight than older homes – great for efficiency, but not so great for fresh air. That’s where mechanical ventilation systems come in, and none are more important than HRVs and ERVs.

What are HRVs and ERVs?
A Heat Recovery Ventilator (HRV) and an Energy Recovery Ventilator (ERV) are both systems designed to continually exchange stale indoor air with fresh outdoor air while salvaging energy. Think of them as the lungs of your home, breathing out the bad air and pulling in fresh air. An HRV uses a heat exchanger core to transfer heat from the outgoing air to the incoming air (in winter) or vice versa in summer. This means in winter you’re not losing all the heat you paid for – the HRV can recover 60–95% of that heat from the exhaust air and use it to warm the incoming cold air. Mike Holmes notes that a well-running HRV **“can recover up to 80% of the heat from the outgoing [air],” reducing ventilation heating costs significantly (makeitright.ca). An ERV does the same heat exchange and also transfers moisture, which can help manage humidity levels year-round. (In humid summer, an ERV helps keep incoming air drier; in dry winter, it helps retain some moisture indoors.)

Why are HRVs/ERVs essential in a renovation? If your project is adding insulation, new windows, or otherwise tightening up the house, you’ll be sealing up the drafts that used to bring in a bit of natural air (albeit inefficiently). Without a ventilation system, indoor pollutants would accumulate more. Building codes in many regions now require mechanical ventilation in new homes, recognizing that tight construction demands fresh air circulation. Even if not required for your renovation, it’s a wise move. A dedicated ventilation system prevents moisture buildup (no more constant condensation on windows) and helps avoid mold. It also continuously flushes out VOCs, odors, and CO₂ that would otherwise stagnate. Instead of relying on random leaks or keeping windows open (which isn’t practical in a Canadian winter or a hot summer in the U.S.), an HRV/ERV gives you controlled ventilation with minimal energy loss. It’s the modern, energy-smart way to ensure a supply of oxygen-rich, pollutant-diluted air inside your home.

Mike Holmes, who has long championed better ventilation, says “My number one way for properly creating an efficient air exchange is by installing a heat recovery ventilator, or even better, an energy recovery ventilator.” (makeitright.ca) That’s strong praise from a home improvement expert, and it underscores that an HRV/ERV isn’t a luxury – it’s foundational to a healthy renovation.

HRV or ERV: which do you need? It depends on your climate and needs:

In colder, drier climates (say, a Canadian prairie winter or northern U.S.), an HRV might suffice, as homes often need heat recovery but not moisture recovery (indoor air can get too dry in winter, but an ERV could help keep some humidity in).
In humid or mixed climates, an ERV is often better because it will help manage the moisture coming in. In a hot, humid summer, an ERV will expel some of that humidity with the outgoing air, easing the load on your AC.
Many parts of Canada and the U.S. now use ERVs even in winter to avoid over-drying the air. For most homeowners, either system vastly improves IAQ – the priority is to have one. If unsure, consult an HVAC professional who can recommend the right system for your region and home.

Whole-House vs. Ductless Systems: During a renovation, you can choose to install a whole-house HRV/ERV that connects to your HVAC ducts or a dedicated duct system. This is ideal if you’re doing major work – it integrates fresh air into all rooms, usually by tying into existing ductwork or using new small ducts. These units typically sit in a utility room and can supply and exhaust air through vents around the home. Many whole-home units come with efficiency ratings (look for high Sensible Recovery Efficiency (SRE) percentages) and various capacities. For example, there are large HRVs that move 200+ CFM of air for big houses, and smaller ones for apartments.

However, if a full ducted system isn’t feasible (say you’re retrofitting an older home without existing ductwork, or only renovating one area), ductless ERV/HRV units are a fantastic alternative. These are often through-wall or single-room ventilators. One popular option is a ductless ERV like the Vents TwinFresh Comfo RA1-50-2, which can be installed in an exterior wall to serve a single room. It’s an all-in-one unit that provides supply and exhaust ventilation for up to ~500 sq.ft., using only about 5–7 watts of power (shop.buildwithrise.com) – extremely efficient. Ductless units usually work in pairs or cycles: they exhaust stale air for a period, storing heat in a ceramic core, then reverse to bring in fresh air, picking up that stored heat. Systems like the TwinFresh or the sleek Lunos e2 ductless HRVs allow you to add ventilation to specific rooms (bedrooms, living areas) without major remodeling or running ducts everywhere. They’re great for condos, older homes, or additions.

In either case, adding mechanical ventilation is a game-changer. Imagine never having to worry about lingering odors after cooking, or paint fumes making you woozy, or excess humidity from showers causing mold. An HRV/ERV keeps air moving and refreshing continuously. And many models come with filters that capture pollen and dust from incoming air, further improving IAQ. Some even have smart controls to ramp up ventilation when CO₂ rises (like when you have a party with many people over).

When planning your reno, make ventilation a non-negotiable item. The cost is usually a fraction of other big-ticket renovations (often on par with an appliance or a few high-end fixtures), but the impact on daily life is immense. As one of your home’s major systems, a good ventilator will quietly protect your health 24/7, behind the scenes. It’s truly the unsung hero of a healthy home.

Solutions and Strategies for Healthier Indoor Air

Improving IAQ doesn’t end with installing a ventilator or using low-VOC paint. A comprehensive approach will touch on monitoring, filtering, and maintaining your indoor environment. Here are some effective solutions and tips – consider these the finishing touches that will ensure your home’s air stays clean long after the renovation dust has settled:

1. Smart Air Quality Monitors: You can’t fix what you can’t measure. That’s where indoor air quality monitors come in. These devices continuously track factors like particulate levels, VOCs, humidity, carbon dioxide, and more. For instance, a device like the Airthings Wave Plus gives you visibility into six key air factors: radon, CO₂, airborne chemicals (TVOCs), humidity, temperature, and air pressureshop.buildwithrise.ca. With a simple monitor, you’ll get alerts if, say, CO₂ is creeping up (signaling it’s time to ventilate more) or if humidity is high (time to dehumidify or check ventilation). Crucially for many North American homeowners, these monitors often include radon detection – a must in areas prone to radon. Health agencies in both the U.S. and Canada urge testing for radon, and a smart monitor makes it easy to keep an eye on this invisible gas. By using air monitors, you gain real-time insight and can proactively manage your IAQ (for example, by kicking up your ERV to a higher setting or opening windows when weather permits). It’s peace of mind knowing your air is being watched even when you’re not thinking about it.

2. High-Efficiency Air Filtration: The air circulating through your heating/cooling system can be a vehicle for dust, pollen, and even bacteria. Upgrading your HVAC filters to high-efficiency filters (like MERV-13 or higher rated filters) will capture much finer particles than standard filters. Many homeowners noticed during recent wildfires or pollen seasons that not all filters are equal – a MERV-8 might let smoke particles through, where a MERV-13 can trap a large portion of them. If your renovation involves HVAC changes, ask for a filter upgrade or an add-on whole-house air cleaner. For example, a whole-house True HEPA air cleaner can be installed in-line with your furnace. HEPA systems are extremely effective – they capture 99.97% of particles as small as 0.3 microns (that covers most common allergens like dust, pollen, mold spores, even many bacteria)shop.buildwithrise.ca. With a HEPA or high-MERV filter in place, every time your furnace or AC runs, it’s also scrubbing the air. Just remember to replace filters on the schedule (typically every 3 months for HVAC filters, and HEPA filters annually or as directed) so they keep working optimally.

If a whole-house upgrade isn’t in the cards, consider a portable air purifier for key rooms. Portable HEPA purifiers can be moved to wherever needs the most cleaning – perhaps the bedrooms at night or living room by day. They’re especially useful if someone in the home has asthma or allergies, or during periods of heavy outdoor pollution (like regional smoke events). Run them on high during activities that kick up particles (sanding, sweeping) or whenever you want an extra clean air boost. The combination of source control (not introducing pollutants), ventilation (removing and diluting pollutants), and filtration (capturing pollutants) forms a powerful triple-defense for your IAQ.

3. Control Humidity and Moisture: Maintaining moderate indoor humidity (around 40-50%) is ideal for both comfort and health (aaaai.org). Too high, and you risk dust mites and mold; too low, and you get dry skin and irritated respiratory passages (plus wood can shrink and crack). During renovations, plan for moisture control:

Bathrooms: Always use a good exhaust fan when showering. If your bathroom fan is old or noisy, upgrade to a quiet, efficient model and vent it outside (not into the attic). Run it during and 15 minutes after showers to remove humid air (canada.ca).
Kitchen: If you’re remodeling a kitchen, install a quality range hood vented to the outdoors (especially crucial if you cook with gas). Cooking can release a lot of moisture and pollutants like NO₂ and grease particles (canada.ca). A range hood dramatically cuts down those contaminants at the source.
Basements and Crawlspaces: Fix any foundation leaks or seepage during your reno. Consider installing a vapor barrier or using spray foam on rim joists to seal out moisture. If the basement tends to be damp, a dehumidifier is a smart addition – many can be integrated into HVAC or stand alone with a drain hose.
Attics and Roofs: Ensure your renovation addresses roof leaks and that the attic is properly vented. Poor attic ventilation or roof leaks can lead to hidden mold that eventually affects the whole house’s air. Similarly, if replacing the roof, add vapor-permeable underlayments that let the home “breathe” out moisture.
After flooding or water accidents: Act quickly. Dry everything out within 24-48 hours (use fans, dehumidifiers) to prevent mold (canada.ca). Materials that can’t dry (soaked carpet, drywall) should be removed and replaced.

4. Low- and No-Toxin Living: Once your renovation is complete and you have a fresh start, keep up the good air quality by choosing healthier everyday products. This means:

Cleaning Products: Many conventional cleaners, air fresheners, and pesticides introduce VOCs (ever felt lightheaded after cleaning with strong bleach or ammonia?). Opt for natural or botanical cleaning products that don’t leave toxic residues or fumes. For example, some homeowners choose plant-based cleaners or a botanical disinfectant instead of chlorine bleach to sanitize surfaces. Not only do these reduce indoor pollution, they’re also gentler for people with chemical sensitivities.
No Smoking Indoors: It should go without saying, but do not allow smoking inside the house. Tobacco smoke is a massive source of indoor pollutants (tar, CO, particulates, formaldehyde, etc.) and sticks to surfaces (“third-hand smoke”). The best air filter is simply preventing those contaminants entirely by keeping smoking outside (far from entrances) or off the property (canada.ca).
Shoes Off: A simple policy – leave shoes at the door. Shoes can track in lead dust, pesticides from the lawn, pollen, and all sorts of outdoor pollutants that then become part of your indoor dust. Using doormats and shoe removal can significantly cut down on unwanted contaminants.
Greenery and Fresh Air: When outdoor air quality is good, open your windows periodically to air out the house (yes, even if you have an ERV – a little extra fresh breeze is nice!). Just check your local air quality index (AQI) or, in summer, pollen counts – if it’s a high pollution day or peak pollen season, rely on your filtered mechanical ventilation instead (canada.ca). Houseplants can be a pleasant addition, but don’t rely on them solely for air cleaning – their effect is very small compared to proper ventilation and filtration. Still, they can contribute marginally and improve mood, so they’re a nice complement to other measures.

5. Regular Maintenance: Maintaining good IAQ is an ongoing task. Include these in your home maintenance routine:

Change HVAC filters regularly (and use the best quality your system can handle). A dirty filter not only fails to trap pollutants but can harbor mold if it gets damp.
Clean air ducts every few years if you suspect dust buildup, especially after a major renovation (construction dust can settle in ducts). However, if you always use good filters, you may rarely need duct cleaning.
Service your furnace and AC annually, and have the heat exchanger checked for cracks (to avoid CO leaks). Ensure gas appliances are properly tuned and vented.
Check and clean your HRV/ERV filters and core seasonally. Most have filters that need washing or replacing and a core that can be slid out and cleaned. This keeps the unit efficient and air streams clean.
Test your radon levels periodically (at least every couple of years, and after any major air-sealing work or seismic events). Radon test kits or continuous monitors will let you know if mitigation is needed. If you already have a radon mitigation system (like an active sub-slab depressurization fan), monitor that it’s working (many have an indicator); fans can run for 5-10+ years, but eventually may need replacement.

By integrating these solutions – monitor, ventilate, filter, control moisture, and use healthy products – you create a robust defense against indoor air problems. Each piece addresses a part of the puzzle, and together they ensure your home’s air remains fresh and safe.

Breathe Easy: Make IAQ Your Top Renovation Priority

At the end of the day, a gorgeous home isn’t truly enjoyable if the air inside is making you sick or uncomfortable. Prioritizing indoor air quality in your renovation is one of the best investments you can make. It’s an investment in your family’s health, in daily comfort, and in the longevity of your home itself.

By following the guidance above – choosing low-emission materials, installing proper ventilation like an HRV/ERV, and adding monitors and filtration – you’ll transform your home into a healthier living space. The benefits will be felt immediately (fewer odors, less dust, more energy and alertness) and for years to come (reduced health risks and possibly higher home value). You’ll also join a growing movement of homeowners who refuse to compromise on the quality of the air they breathe.

So as you plan your next renovation, put IAQ at the top of your checklist. Imagine a home where every breath you take is clean and pure – no more worrying about hidden toxins or stale air. That vision is entirely achievable with today’s technology and products. From energy-efficient ERVs to smart air monitors to eco-friendly paints, the tools are available at your fingertips (many of which you can find at Rise’s own marketplace of vetted healthy home products).

In making indoor air quality your #1 renovation priority, you’re doing more than a home improvement – you’re improving your life. A home with healthy air is a home where you can truly relax, knowing your environment is supporting your well-being. And after all, isn’t the goal of any renovation to create a space where you and your loved ones can live better? With fresh, clean indoor air, you can literally breathe easier and enjoy your beautiful new space to the fullest.

Just check your local air quality index (AQI) or, in summer, pollen counts – if it’s a high pollution day or peak pollen season, rely on your filtered mechanical ventilation instead (canada.ca). Houseplants can be a pleasant addition, but don’t rely on them solely for air cleaning – their effect is very small compared to proper ventilation and filtration. Still, they can contribute marginally and improve mood, so they’re a nice complement to other measures.

5. Regular Maintenance: Maintaining good IAQ is an ongoing task. Include these in your home maintenance routine:

Change HVAC filters regularly (and use the best quality your system can handle). A dirty filter not only fails to trap pollutants but can harbor mold if it gets damp.
Clean air ducts every few years if you suspect dust buildup, especially after a major renovation (construction dust can settle in ducts). However, if you always use good filters, you may rarely need duct cleaning.
Service your furnace and AC annually, and have the heat exchanger checked for cracks (to avoid CO leaks). Ensure gas appliances are properly tuned and vented.
Check and clean your HRV/ERV filters and core seasonally. Most have filters that need washing or replacing and a core that can be slid out and cleaned. This keeps the unit efficient and air streams clean.
Test your radon levels periodically (at least every couple of years, and after any major air-sealing work or seismic events). Radon test kits or continuous monitors will let you know if mitigation is needed. If you already have a radon mitigation system (like an active sub-slab depressurization fan), monitor that it’s working (many have an indicator); fans can run for 5-10+ years, but eventually may need replacement.
