Easily fits into the frame, provides significant filtering for next 6 months. A fine product at a good price.

These are great filters that trap so much dirt etc. I replace my filter every 3 months so I need a quality- affordable product and this one does not disappoint. I replace them myself and it is very easy. I can tell when it is tile to change the filter as my furniture is dusty.
