Verified Purchase

I recommend these air filters. This is the second time I have ordered these air filters and have been very pleased with them. I have two intake openings and order both sizes.

Quality product!

These look well made and were packaged good. I will be changing out my existing filter next month and will be able to udate my review with how they performed at a later date.
