Installed first one yesterday. The filter was about an 1/8 of an inch too big, but a little persuasion I got it in.The filters are quality made and very reasonable prices.Would highly recommend. Super fast delivery as well.

The new 11 filters look great and I am looking forward to starting to use them as soon as the last of my old filters need to be changed, in a couple of months.

Used to love these filters, but the latest version is slightly oversized so we have to bend it to get it in place. Also the new color is visible through our ceiling vents, wish they were white like the prior version.
