Tips to Improve Indoor Air Quality

When you think about pollution, you probably picture smoggy cities or busy highways—not your living room. But indoor air can actually be more polluted than outdoor air, especially if your home isn’t well-ventilated or your HVAC system isn’t properly maintained. Dust, allergens, pet dander, and even cleaning products can quietly affect the air you breathe every day. That’s why The Maynard Man is here with simple, effective ways to freshen up your indoor air and make your home a healthier place to live. From filter changes to better ventilation, these tips don’t require a full remodel—just a few smart shifts in routine. Let’s break down how to get cleaner, healthier air starting today.

Replace or Upgrade Your Air Filters

Your HVAC air filter is your first line of defense against airborne particles—and when it gets clogged, it can’t do its job. Over time, filters collect dust, pollen, pet hair, and other pollutants, which not only affect your air quality but also restrict airflow and strain your system. That’s why it’s important to replace them every 1–3 months, depending on how often your system runs and whether you have pets or allergies. If you want to take your air quality a step further, consider upgrading to a high-efficiency filter. Look for filters with a higher MERV rating (but still compatible with your system), which can trap smaller particles and reduce the spread of allergens throughout your home.

Keep Vents and Ducts Clean

Even with a clean filter, dust and debris can still build up inside your vents and ducts over time—especially if you’ve recently done renovations, have pets, or live in a high-pollen area. That buildup can affect both airflow and air quality, circulating unwanted particles every time your system turns on. Start by vacuuming around your supply and return vents to remove surface dust and prevent clogs. If you notice dust blowing out of vents, a musty smell, or a visible coating of debris inside, it might be time to schedule a professional duct cleaning. A thorough cleaning not only freshens the air but helps your system operate more efficiently.

Control Humidity Levels

Moisture in the air plays a big role in your home’s overall air quality. Too much humidity can lead to mold growth, dust mites, and musty odors—especially in basements, bathrooms, and kitchens. On the flip side, air that’s too dry can irritate your throat, worsen allergy symptoms, and even damage wood floors and furniture. The ideal indoor humidity level falls between 30% and 50%. You can use a hygrometer to monitor it, and adjust accordingly with a dehumidifier in damp areas or a humidifier during the dry winter months. Keeping moisture in check helps create a balanced environment that feels better and supports cleaner air.

Improve Ventilation Where You Can

Stale indoor air can trap pollutants and create a stuffy, unhealthy environment—but even small changes in ventilation can make a big impact. On mild days, opening windows and doors for just a few minutes helps flush out indoor air and bring in fresh oxygen. It’s one of the easiest ways to refresh your space naturally. In rooms that collect moisture or odors—like bathrooms, kitchens, and laundry areas—make sure exhaust fans are in good working order and use them regularly. These fans pull out steam, cooking fumes, and airborne particles that would otherwise linger and spread. Better airflow means fewer pollutants hanging around in your breathing space.

Add Air-Purifying Solutions

Sometimes your HVAC filter alone isn’t enough—especially if you have allergy sufferers at home or live in an area with heavy pollen, pet dander, or pollution. Portable air purifiers can be a great addition, particularly in bedrooms or living spaces where you spend the most time. Look for models with HEPA filters to trap fine particles like smoke, dust, and airborne bacteria. For whole-home air improvement, consider asking your HVAC technician about built-in purification systems like UV lights or media air cleaners. These can neutralize bacteria, viruses, and odors at the source, giving your entire home a fresh-air boost. It’s an extra layer of protection for the air you breathe every day.

Be Mindful of Indoor Pollutants

Sometimes improving your air quality means rethinking the products and habits you use inside your home. Many everyday items—like aerosol sprays, scented candles, and conventional cleaning supplies—release volatile organic compounds (VOCs) into the air. These invisible chemicals can linger long after you stop smelling them and may contribute to headaches, respiratory irritation, or long-term health concerns. To keep your indoor air safer, switch to low-VOC or fragrance-free alternatives whenever possible. Choose non-toxic cleaners, avoid burning candles for long periods, and make sure any painting or refinishing projects are done in well-ventilated areas. Even simple swaps like opening a window while cleaning or skipping artificial air fresheners can make a noticeable difference.
