1. Keep your air ducts clean. The air ducts in your heating and air conditioning system are traps for dust, pollen, mold, and other contaminants. Changing out your air filters on a regular basis will help to keep air flowing through your HVAC system, but having your ducts cleaned out by a professional is the surest way to keep potential allergens from getting into your indoor air.
2. Improve your ventilation. Artificial ventilation can help to ensure a healthy circulation of air inside your house, which will dilute pollutants that are already in your air. A fresh air intake system will allow fresh air to enter your home when needed, and a whole-house fan system will prevent stale air from lingering in your house.
3. Install air cleaners. One effective way to keep your indoor air clean is to install air purifiers. You can install whole house air cleaners and purifiers to keep your house, , and the air in your house, free of contaminants. There are a number of air cleaning systems on the market, so talk to an HVAC professional about finding the system that is best suited for your needs.
4. Buy a humidifier or dehumidifier. To keep bacteria and mold out of your home, it’s important to keep your home from becoming too humid. Low humidity, on the other hand, can dry out your sinuses and make you more vulnerable to allergens. High humidity can cause moisture smells and mold to grow in your house .Installing a humidifier or dehumidifier, as recommended by your HVAC professional, will help keep your home comfortable.
