Poor quality

The sides of the filter frame are not glued properly. I had to glue it together so it won’t fall apart during usage.

Great filters! Have 2 dogs and they really keep the air clean!!
These filters are so much better than what you can get at the large warehouse stores and they are competitively priced!
