I have always wondered if HEPA filters are worth the money or not, however my dad used to swear by HEPA brand air filters whenever I was growing up, although I have never used them in my cabin since I bought my own locale, however first of all, I feel like the indoor air quality of my cabin is just fine the way it is; Secondly, HEPA filters are way more costly than other air filters are, and i just realized this a couple of months ago when I went into the local home improvement store to buy air filters for my heating in addition to cooling system. I ran out, in addition to this was one of the first times that I have ever gone to purchase air filters myself. never easily thought about it before. I always just grabbed the first air filter that I saw that looked like it would fit my heating in addition to cooling system; This time when I went into the store, though, I easily looked at everything in addition to started doing some comparison shopping. That’s when I realized how much more HEPA air filters cost than the official store brand air filters! When I started looking at them, I couldn’t easily tell all that much of a difference. It did get me started on wondering why in the world they were priced so differently, though. That’s when I started to do some research on different types of air filters! And honestly, once I started reading about the wonderful things that HEPA filters do for your indoor air quality, I decided to beginning using them too.
