GOOD QUALITY

These filters are a huge improvement over the standard filters we have been using. The air is noticeably cleaner and no particles or cat dander whatsoever.

I have tried using different kinds of filters. After using these Ultra Allergen filters for a year, I just received another order. Why? Because they work. The air is cleaner and less dust on furniture. It's a big deal to be able to breathe.

These are the best filters I have ever purchased. They cut dust to a minimum making house cleaning for me so much easier. And such a great value for an average of $10 each. I replace them every 2 months.

Just bought the 14x30x1 merv 12, it is full size, therefore will not fit into wall slot. It should be at least 1/8" smaller all around. Dissappointed, package states it is 13 13/16 x 29 13/16, it is NOT.

It is a good filter, but I’ve been told now by three different air-conditioning companies that they are too hard on your air condition unit and it makes them work too hard and to go to a lower grade.
