Great process, easy and a great value. We've had the filter in for a bit now and notice a change in the air smell and quality.

Just a touch smaller than the opening

Filter labeled as correct size , it’s a little smaller than the opening which causes it to whistle or fall out of place. When unit comes on you can hear filter suck back into a position

Fits perfectly into the furnace where other filter brands have fought to fully go in. The price of these filters are excellent as well

First time not been but two weeks. But my concern is the whistle noise I notice on return. I purchased several and I will try the next one to see if it continues
