We loves these filters. They only have to be changed once a year. The ones in the store are true to size which is a tad too big for our unit. Your filters are a bit smaller and fit perfectly.

All I can say right now is they fit my system, very close to being short on the sides. Can not speak on the performance yet because I just installed it.

Great value for the money. Package was delivered pretty beaten up and customer service was so easy! Great company!

Shame on me for not reading more closely. Even though prominently listed and sold as a 20x25x4 filter, the details in the ad do disclose the actual dimensions are only 19.5x24.5x3.75. This will not work in a standard US AC unit requiring a 20x25x4. Amazon, you should remove this listing.

The filters seem well made and sturdy. They arrived in good condition fairly quickly. They fit well in the filter box..

Purchased these instead of much more expensive ones from a local store. They are a perfect fit and just as good quality as ones more expensive.
