You know, I always knew there were different kinds of heating and air conditioning filters, but I never thought they made much of a difference.
I figured that it was just different brand names that served the same purpose equally. However, I found that some brands truly are better. I used to get the cheapest quality A/C filters I could find, but that was really harmful for my air conditioning system, as well as it didn’t do a great 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 and air conditioning machine, I felt like my air was cleaner, and I also noticed my air conditioning machine seemed to be working slightly more efficiently as well. I was shocked, all this from just a simple air filter change? It made me wonder what else I could change for maximum efficiency of my heating and air conditioning system. After that experience, I decided that I was going to start buying HEPA air filters all the time. I don’t think I could ever see myself going back to the cheap crappy air filters that I was used to previously. If you have a central HVAC unit, and you don’t have HEPA air filters, I would highly recommend them. They really do work so much better! I am going to read more about heating and cooling later, to see what else I can learn.
