Product review (4 stars): Good filters
I can spend a lot more at home depot than these which are about half the price and these work just as good.  They are not quite as "thick" as the ones at home depot but they work just the same and last just as long as far as i can tell. I just wish the life on the filters was a little bit longer than they are.  I use the humidifer conditioner but it still only lasts about a month before i have to replace them.
