10 Tips to Improve Indoor Air Quality for a Healthier Home

Clean, fresh air is essential for a healthy home — yet studies show indoor air can be up to five times more polluted than outdoor air. Poor indoor air quality can lead to allergies, asthma flare-ups, and long-term respiratory issues.

Here are ten practical steps you can take today to create a healthier home environment and breathe easier.


1. Keep Your Home Clean and Dust-Free

Dust, pollen, and pet dander build up quickly and recirculate through your HVAC system. Vacuum floors and carpets weekly with a vacuum that has a HEPA filter, and wipe down surfaces with a damp cloth to trap dust rather than spread it around.


2. Ventilate Your Home

When weather allows, open windows and doors to let fresh air in and stale air out. Install and use exhaust fans in kitchens and bathrooms to reduce moisture and prevent mold growth.


3. Eliminate Indoor Smoking

Cigarette smoke contains hundreds of harmful chemicals that linger in the air. If someone in your household smokes, designate a well-ventilated outdoor area for smoking to keep indoor air clean.


4. Choose Natural Cleaning Products

Many household cleaners contain VOCs (volatile organic compounds) that pollute indoor air. Switch to natural alternatives like vinegar, baking soda, and lemon juice for an eco-friendly, non-toxic clean.


5. Control Humidity Levels

Keep humidity between 30–50% to prevent mold, mildew, and dust mites. Use a dehumidifier in damp spaces like basements and ensure proper ventilation in bathrooms and kitchens.


6. Maintain Your HVAC System

Your HVAC system is your first line of defense against poor air quality. Change filters regularly (at least every 90 days or more often with pets), and schedule professional maintenance twice a year to keep your system clean and running efficiently.


7. Add Houseplants

Plants like snake plants, spider plants, and peace lilies naturally remove toxins like formaldehyde and benzene from the air. Place a few around your home for a natural air-purifying boost.


8. Avoid Synthetic Fragrances

Air fresheners, candles, and scented sprays often contain chemicals that degrade indoor air quality. Opt for fragrance-free products or use essential oils in a diffuser for a natural scent.


9. Keep Outdoor Pollution Out

Use doormats at every entrance and encourage family members to remove shoes before entering. Close windows on days with poor air quality or high pollen counts.


10. Test for Radon

Radon is a naturally occurring, odorless gas that can increase lung cancer risk. Conduct a simple radon test to ensure safe levels. If elevated levels are detected, contact a mitigation specialist.


Improving indoor air quality takes consistent effort, but the payoff is worth it — fewer allergies, a healthier home, and a more comfortable living space.

The technicians and installers at Rox heating and air are friendly, professional and helpful. Roger, Bert and Ty were professional, helpful and always willing to answer questions. They worked quickly and it was obvious that they had an abundance of experience installing systems.

I've been a customer of Rox air for a few years. Both for air and heating but also water heater. I am on there maintenance plan and they come out twice a year and do a thorough job checking out the systems. They spend a lot of time to make sure everything is working right for the next season. I would recommend them to anyone.
