You know, I constantly knew there were strange kinds of heating & A/C filters, however I never thought they made much of a difference.
I figured that it was just strange brand names that served the same purpose equally.
However, I found that some brands actually are better. I used to get the cheapest quality A/C filters I could find, but that was really harmful for my A/C, and it didn’t do a good job of cleaning the indoor air quality of my home. It wasn’t until I got a free HEPA air filter that I realized the difference. After trying a HEPA air filter in my heating & A/C machine, I felt like my air was cleaner, & I also noticed my A/C equipment seemed to be working slightly more efficiently as well. I was shocked, all this from just a easy air filter change? It made me wonder what else I could change for maximum efficiency of my heating & A/C. After that experience, I decided that I was going to beginning buying HEPA air filters all the time. I don’t suppose I could ever see myself going back to the cheap crappy air filters that I was used to previously. If you have a central Heating plus Air Conditioning unit, & you don’t have HEPA air filters, I would highly propose them. They really do labor so much better! I am going to read more about heating & cooling later, to see what else I can learn.
