The filters are great. I

The filters are great. I don’t have air conditioning so I only use my furnace three to four months out of the year. I change the filter once a year and I have 6 in stock now.
Please discontinue any future automatic purchases. I’m looking forward to your response. Thank you.

Cheaper because they are smaller?

These filters are smaller than the 20x25x4 Honeywell filters I had been purchasing at the big box stores to the point they dont really fit very well.

16x20x4 filter review
on March 18, 2026

The filter is so undersized that I had to use the Honeywell case so it would not fall off the support rails. If I buy again, it would have to be a custom size. Which doesnt make sense to me.

I have ordered before. I have a service that checks my ac a couple of times a year. I like to have your filters ready for the air cleaner. Makes all the difference

I like the product. Isnt that enough? Quit sending multiple emails wanting a review. If I ignore the first Ill likely ignore them all. Dissatisfied customer with your review process. Love the filters.
