The Environmental Protection Agency (EPA) says that indoor air pollutants may impact your health more than outdoor pollutants. Here are some easy ways to improve the air quality in your home. 1. Learn how to keep allergens at bay. Dust, mold, pet hair and dust mites are all common allergens present in many indoor spaces. They can be removed from your home by ensuring your house is thoroughly cleaned and pets are brushed and bathed regularly. 2. Invest in an air purifier. Air purifiers with a high-efficiency particulate absorbing (HEPA) filter can remove over 99% of harmful air particles. however, they can’t remove all types of pollution from the air. 3. Improve ventilation. Regularly changing the filters of heating and cooling systems and ensuring air ducts are clean is a simple way to improve air quality. Opening doors and windows is another very easy way to let air flow through your home.
