It is so nice to save so much money and still get high quality air filters. I have asthmatic kids so I have to buy high end filters. I also have 4, count them, 4 filters in my home, 3 different sizes. Its was running 70$ every 3 months for filters. This is a much better, economical way!

Fast shipping Didn't like that I could only get 14x14 in 1 inch. I actually need a 2 inch. Still need to put my mesh filter so the new filters don't move when the air kicks on
