I’m impressed with the wide selection of filters on your site. This particular filter is nowhere near me as I shopped around locally. I am happy to purchase it from you. It is also a plus and is great service to have the opportunity to be on an automatic filter change program.
I would recommend it to anyone!

Good filler but a little too big

The filter works great, but sometime last year they redid them and now they're a little too big for my unit. I have to squish the filter box some and jam it in, even though the filter size says it's correct.

We just got them and had the first one put in. It’s too soon to tell whether I’m gonna like them or not.
