Did you know that the air you’re breathing inside your home can be 5 times dirtier than the air outside? It’s true, assuming you don’t live in a developing country. This is because the air inside your home gets recirculated constantly by your heating and air system and becomes stagnant.
Heating and air systems do this to conserve energy. It’s much easier to keep cold air cold than taking in the hot air from outside and trying to make it cold. While having the intake point inside makes energy sense, it does create some potential health issues.
Pollutants like pet dander, pathogens, dust mites, mold, and pollen can all be continually recycled by the heating and air system if proper precautions aren’t taken. Thankfully, keeping the air clean inside your home doesn’t require a lot of time or energy (from you or your heating and air system).
One of the best ways to improve the air quality inside your home is to change your air filters every three months. This will stop sickness-causing pollutants from getting in the air supply and keep your home healthy. There are different levels of air filters that range in price and degree of filtration. If you frequently suffer from allergies or have pets, bucking up for the premium air filters will be well worth it.
For homeowners who really want the cleanest air possible, a UV light will do wonders. By installing a UV light in the ductwork of the heating and air system, airborne microbes will be stopped in their tracks before they can enter your home. There are two types of UV lights for heating and air systems - coil and air sterilization. The coil sterilization is installed inside the return air duct near that sterilizes the air handler coil. While the air sterilizer cleans the moving air. The UV light unit is installed in the return air duct and cycles on and off with the system.
UV lights are great for killing mold and other microbes, but they aren’t great for pet dander and dust. This is why it’s so important to change your filters even if you have a UV light for your heating and air system.
