We’ve written before about how houseplants can improve indoor air quality. Recently we decided to take that advice seriously and added a few English ivy plants to our collection, alongside our Boston fern and Burro tail. Bringing in more plants felt like inviting a quiet army of natural air purifiers into the home, and it made an immediate, calming difference.
Along with plants, we tackled a few practical maintenance tasks that also help keep indoor air fresh. One of the simplest and most effective steps is replacing the air filters for your heating and cooling system. Aim to change filters every three months. For years we were lucky if we remembered to change them only once in winter and once in summer. This time, our programmable thermostat helped: it lets us record the date we change the filter and then gently reminds us when the next change is due. Small technology, big help—those reminders make routine maintenance far less likely to slip through the cracks.
We also installed an additional carbon monoxide detector/fire alarm near our gas fireplace in the den. Many modern alarms are dual-purpose, combining smoke detection with carbon monoxide sensing, which is a useful space-saver and simplifies safety planning. Gas fireplaces, gas stoves, wood-burning stoves, and gas heaters are among the most common sources of carbon monoxide in homes, so placing detectors near those areas is a practical precaution.
Carbon monoxide is not something to take lightly. We recently heard a chilling account about a mother and her young son who almost succumbed when carbon monoxide filled their home; the mother awoke disoriented and managed to get herself and the baby outside in time. That story underscored why having more than one detector is important. We now have one in the bedroom and one at the other end of the house near the den, providing broader coverage and much-needed peace of mind.
Beyond plants, filters, and detectors, there are several practical habits that help maintain cleaner indoor air. Regular vacuuming with a HEPA filter vacuum, dusting with a damp cloth, and washing bedding frequently all reduce the amount of dust, dander, and particulate matter circulating in the home. Controlling humidity with dehumidifiers or exhaust fans in kitchens and bathrooms can limit mold growth, which also contributes to healthier air. When weather allows, opening windows for short periods to bring in fresh air can dilute indoor pollutants without compromising comfort.
Another simple habit is to adopt a consistent schedule for air filter replacement. If you don’t have a smart thermostat that tracks filter changes, set a calendar reminder on your phone or leave a note on the HVAC unit. Keep replacement filters in a visible spot so you’re more likely to notice when it’s time to swap them out. For households with pets or citizens with allergies, more frequent filter changes—every 30 to 60 days—can make a noticeable difference.
Small upgrades, like installing a second carbon monoxide detector and adding a few hardy air-purifying plants, combine with regular maintenance to form a straightforward, effective strategy for cleaner indoor air. The effort is minimal compared with the comfort and safety benefits. How do you keep the air in your home fresh?
