Order arrived fast and in great shape

The carcboard frame and the material used to enforce the filter are subpar. After several weeks, especially as furnace is used more due to colder weather, they collapse inward and become useless. Doj't waste your money.

Works better than most filters! Great product ! Love it!

We were recommended by our HVAC guy to use a lower MERV count which led us to purchasing these filters. We’ve been using this style for a little over a year at this point. They seem to only last 1-2 weeks before they start whistling and we usually give in around week 3 and replace them because they are so loud. I just don’t think the structure of this particular filter is strong enough.

My unit was roaring and I checked filter, which I had replaced not too long ago. It was very hard to remove and was sucked up against fan. It was installed according to arrow, but the support was on the bottom side, not top to protect from fan. I changed filter and reversed direction. Will replace with another brand and style that fits and supports filter correctly.
