It's a filter. It fits and it works. Not very pretty, but it sits inside the furnace so who cares? Good price and fast shipping.

Bought 5 of the Merv11 Filters for my hvac air conditioning unit. My Size is hard to find in stores here in Melbourne FL. The summer is upon us and just had my a/c unit serviced so were ready to go! Love the discount with this brand, the more you buy the better the price! Saves me on this necessity and will continue to get my filters online-super fast shipping with Filterbuy! Thank you

Four inch filter that fits!
on April 12, 2025

Biggest thing is, this 4 inch filter fits. The filters at the two big home improvement stores are both over 4 inches thick. And wont fit into my furnace. These are sized to fit into a 4 inch opening. Perfect!Shipping is fast and the price is right!
