A clean house makes for better air quality [link to https://1stchoiceheating.com/indoor-air-quality/] since proper interior hygiene may significantly reduce dust and animal dander. Pay attention to the following:
Vacuum the carpets and area rugs at least once or twice a week using a HEPA-filtered vacuum cleaner. Choosing hard-surface flooring over wall-to-wall carpeting may also help to reduce allergies in the house.
Clean bedding, draperies and other furnishings that draw allergies on a regular basis, especially if you have pets. The American Academy of Allergy, Asthma, and Immunology suggests washing in water that is at least 130° F. When feasible, use dust mite–proof coverings on pillows, mattresses, and box springs.
Change your filters every month. If you have a forced-air heating system, you should change the filters on a regular basis. Dust and other airborne irritants can be caught by electrostatic filters rather than being recirculated throughout your house. Consider getting your ducts cleaned to eliminate any dust that has accumulated.
