I’m very fortunate to have a nice air filter in my home. I know that they’re not as many people that are lucky enough to have a HEPA filter as nice as mine. I guess I’m just lucky because I was able to buy these filters on sale at my local heating and AC business. These specific types of filters only fly off the shelves like hotcakes! The moment they come in they’re gone. Everybody wants one in my area. This is because in my area unfortunately the indoor air is heavily polluted and nobody wants to breathe in bad indoor air quality. So everybody grabs up these filters really quickly. Some of the most popular items I sell at the heating and coin store are items like indoor air cleaners, UV light filters, and even some whole home air purification systems but only the really rich can afford those. The next most popular items would have to be smart thermostats, if they can’t get a good air filter then they’ll use the smart thermostat to have good indoor air quality. I have some of the best indoor air quality in my neighborhood and that’s because I put a lot of time and money into investing in my heating and AC system. It isn’t the cheapest way to do things but it’s hard work for me and that’s what I really like about it. My HEPA filter has preserved me well for many years now and I doubt that that will change anytime soon.
