Works perfectly in my home

Good filter at a reduced price

Awesome value awesome air quality

Primo filters for furnace.

I have used these filters for years they always work well for what they do

Great price, fast delivery

Hreat filters for my system. I will buy them again.

They seem to clean the air pretty well

About $8 per filter. Best filter I’ve ever purchased. Recommend changing monthly not every 90 days

Excellent to help with the dusty days!
