A few small changes—like switching to a HEPA filter or adding a houseplant—can make the air you breathe noticeably cleaner.
Indoor air quality plays a significant role in our everyday health and comfort, especially during the warmer months when we tend to keep windows closed and air conditioners running. From reducing allergens and dust to filtering out pollutants, there are several simple ways to refresh the air inside your home, and it starts with just a few thoughtful changes.
Start with Houseplants
Some houseplants can help reduce certain airborne pollutants and contribute to a more comfortable indoor environment. While they aren’t a replacement for air purifiers or proper ventilation, plants can enhance indoor spaces and support better air quality. Popular low-maintenance options include:
- Snake Plant
- Spider Plant
- Peace Lily
- Aloe Vera
- Bamboo Palm
These plants are not only easy to care for, but also add visual appeal while naturally filtering some toxins commonly found in household products. To dive deeper into plant options and how to care for them, check out our article Growing Plants in Your Home, Sustainably.
Use an Air Purifier
An air purifier is one of the most effective tools for improving indoor air. Look for models with HEPA filters, which are specifically designed to capture small airborne particles, including dust, pollen, smoke, pet dander and mold spores. Many units also include carbon filters to help reduce odors and chemical fumes.
Home Depot offers a range of air purifiers, including models suitable for bedrooms, living rooms and whole-home systems. Consider:
Maintain HVAC and Air Filters
Your heating and cooling system plays a big role in circulating air throughout your home. To keep it working efficiently, change air filters every 1–3 months based on your usage and filter type. Opt for high-efficiency filters, such as those with a MERV 11 rating or higher, to better trap airborne particles. Additionally, schedule regular HVAC maintenance to ensure your system runs smoothly and your air ducts remain clean and effective.
Watch What You Bring Indoors
Household cleaners, paints and synthetic fragrances can emit volatile organic compounds (VOCs) that may affect indoor air quality. When possible, choose low- or no-VOC products, ventilate rooms during and after use, and store chemicals in an area outside your main living space. For example, when preparing to paint your home, consider BEHR, an Eco Actions Partner, which offers low- or no-VOC paint products designed to have a lower impact on indoor air quality while still delivering beautiful results.

Reduce Dust and Moisture
Dust, pet dander and excess moisture can all contribute to poor air quality. Keep surfaces clean and consider using a vacuum with a HEPA filter, washing bedding and curtains regularly, and placing a dehumidifier in damp spaces like basements to help prevent mold growth.
Clean air at home starts with the choices we make every day. From natural additions like houseplants to efficient tools like air purifiers and HVAC filters, there are many ways to improve your indoor air quality. With the right approach, you can create a healthier, more comfortable living space for your entire household.
