MERV 13 Replacement for Lennox 20x20x5 (19.75x19.88x4.38)

Very easy and fit perfect

I found Filter Buy on line and ordered from them based on previous reviews. They shipped the filters quickly; when I realized that I ordered the wrong size, they promptly refunded my money and shipped the correct ones. Even better, I was told to donate the wrong ones. That will make it possible for someone to purchase them at a reasonable price. What an awesome gesture. I'll be a long term customer with them. Wish transactions with other vendors would go as smoothly as this one.

Excellent product excellent service. They go the extra mile for satisfaction. Would definitely order again and again!

Good product, easy to order, very good
prices & fast delivery

We ordered on line and received it in a week I think. The Customer Service people were friendly. We put the filter in as soon as we got it and had no problem. Also the price was reasonable.
