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.

Wondered why it took so long to warm the house and seemed to cycle more than usual then this morning it cycled way too often and would not warm the house. Finally realized the arrow for air direction they printed on filter appears to be backwards because the point of arrow is on side without the extra netting that goes on the blower side. I can only hope no damage was done and it already cost me an unnecessary service call.
