Easy to install, fit perfectly. Very happy with item.

Fit perfect. Great price

My older ductwork was made with an odd filter size, not available at any big box store. Really pleased to find these filters at a reasonable price.

Fits my heater perfect! Looks to be very good quality. We haven't used the heater yet but my guess is once it's time this product will function perfect.

The filters are working great. So glad I found them and they were delivered so fast.
