Perfect Fit

Originally purchased the stated size for my hvac system from a big box store. It didn't fit. The reason why, I discovered is that the actual inside dimensions of the filter required is smaller than the one purchased. These perfectly fit my Lennox system.

Furnace Filter Success Story

I was able to order exactly the correct size at a lower cost online than from a store. The package was delivered in great shape and earlier than predicted. Overall I'm very satisfied with Walmart, SameDaySupplier and FedEx.
