Great filters. They fit perfectly and having them delivered is very helpful in remembering to keep them changed.

I have a relatively new system and I realize the importance of a great filter. These FilterBuy filters are so easy to order and remind me when it is time. I could not believe how much dust was on my used one. Excellent filter!

I dont like the green edges bc they show through my vents. Wish the edges were white like the actual filter.
