I had been hearing all about washable air filters for the longest time as well as had never tried them before until recently! I have to tell you that since I have tried washable air filters I am never going back to regular air filters again! Washable air filters are simply much easier to deal with than regular air filters, and with washable air filters I find myself being able to save money from not having to buy air filters as often, then and since I go to the store physically to buy air filters… I guess that this is also saving myself and others a lot of hassle of having to go out every other month to the hardware store! Anyone who doubted washable air filters as well as wouldn’t try them. I can definitely assure you that they do what they say plus more. I happened to buy the top HEPA brand washable air filters, as well as with these HEPA washable air filters I found myself not having to change the air filter in our central heating as well as a/c method for a few weeks verses having to change the air filter every single month like I used to when I was buying regular non-washable air filters. I suppose that washable air filters are going to be the future once everyone gets a chance to start trying these things out, however they absolutely are the greatest air filter to ever come on the market! Especially when you buy HEPA brand washable air filters, but you will never see myself and others buy any other kind of air filter ever again after this!
