My husband and I train dogs and these filters keep the allergens, dust etc out. We all breathe better especially the pups that have seasonal allergies!

Not the Correct Sizze

We purchased 30x30x1 filters and upon receipt and installation they appear to be too small. Every time the AC kicks on, the filter is sucked thru and becomes dislodged and falls to the back of the opening. They appear to be very flimsy so when they are pulled backwards, the filter becomes bent and twisted. We have had to duct tape them inside where they belong to get them to hold into place.
