Best For Allergies

I have severe environmental allergies and these filters are life savers! I change mine every two months or so, it all depends on how much you use your central air conditioner and heater. Don't waste money on cheap replacements, you'll end up suffering with allergies and buying the quality filters in the end.

Long lastingsturdy and sturd

I've used cheap filters before but by the time i had to buy more I felt like i was paying more and spending more time checking on them to see if they were still filtering properly, but with the humidity down here in the south, sometimes they would just wilt or fold in and leave gaps when Ileast expected it. This one seems to hold up and honestly just feels like its better quality. Not like I'm an expert on air filtration but after having lived for forty years in all kinds of conditions you become experienced in what to look for with this kind of stuff because I've myself have lost money on cheap filters and seen others in the same boat that had their lines frost up or the whole AC unit freeze up with ice just hecause of a filter that wasnt seated properly or was wilted with dampness. These just seem to work like i would expect a filter to work and last just enough where the costs and worry seems to be worth the price. plain and simple I like quality and these seem to be good quality.
