Works fine!
Not sure what to say other than it works and I’ve stored them in the back closet they take up a lot of space but great value 😂

Great value
This is the same brand the tech installs when they service my furnace. It supposedly will take a 4 inch filter, but the brands sold at the big box stores in a 4 inch size absolutely will NOT go in to my Lennox furnace. These are 3 3/4" in height which is probably why the service techs use them. This is the only brand I can find that will fit, and it's a great price for the money. Highly recommended, particularly if you have pets / kids and change filters often.

great product
Need to change the filter annually. In prior years I had the HVAC company install a new one when I had the annual maintenance check. I bought 5 filters from Amazon cheaper than the cost from the HVAC company.
