Buy Quality Furnace Filters in Bundles.

This is a great deal. When you can buy QUALITY furnace filters for less than half price of your local retailer, then you've found a great deal.

I need to return them. They do not fit, even though the measurement seemed to be correct.

Great product at great price

Unbelievable how some companies charge way too much for a lesser quality product. I purchased the Merv 13 pleated filter, 16x25x4 and couldnt be happier. The price was equivalent to what others wanted for a basic low quality filter. They were shipped in a timely manner and I received them in just 3 days. Fit is perfect and time will tell on the performance.

Filters seem fine, but the thin cardboard frame is a little too flimsy. . they arrived quick enough, but we're a little beat up. Over all good at a little better price.
