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.
