It fits perfectly, unlike others in the same size, and it works very well. Living in a very heavy pollen area, these work very well. I change them out every three months during summer and once a month during heavy pollen times. I highly recommend them.
Filter is a filter and it does what it should do - and does it well. Five stars for this company. Very easy to deal with. When I screw up my order they are just so smooth and nice about fixing the problem
I am not to keen on the thick blue inside to filters. I have always used filtrete.To be fair have not used one yet but will certainly let you know if they are rffecient
