I've tried all kinds of filters. These aren't the best filters you can buy but I'll tell you for the money they work great. I have a friend in the industry who advised me to stop buying insanely expensive filters and just buy cheaper filters and replace them more often. After using them for 3 months I found that they work just as well as a similar brand I can buy in a big store. And I really like that I've been able to find the ones I like online so I can just order them from Revain. Fan all the time in the house. 24/7 I do this because the house is better balanced that way. winter and summer. There's a big debate going on about whether to leave the fan on or leave it on auto. You can read this debate and decide for yourself if it's worth it. But just know that I work 24/7 and use these filters. And I just think they're great.
