These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

Great price on a great product. We have a couple of rescue dogs that shed. That means I always have a need to change my filter often and to always use a good one. This fits that perfectly.

These were a perfect fit and are doing a great job! With a pug (known for heavy shedding) and a smoker in the house, these filters have made a big difference in the air quality. Great price and fast ship too.

A necessary piece of equipment for every home’s furnace. I know price is a topic to avoid but compared to a 10 pack bought last year the cost has crazy skyrocketed! The only negative in this review.

I had been using a cheaper change every month filter and decided to try these. They are made much better so thinking they may last two to three months. So far happy with my purchase.

I believe the filters are good but the first one I put in seemed to get used up pretty quickly. Also didn't appreciate having to pay the shipping fee because they didn't have my size in store.

Since I have terrible allergies, I appreciate the utmost filtration of the air inside my home. These help achieve lower pollen count inside my home, therefore improving my quality of life.

Hi quality filter that works great. We change the filters every three months, seems about right here in the desert southwest. Great price at Sam's for a 4-pack, and usually in stock when we need to restock.

Love these filters!! I have been using them for a number of years now and have figured out that changing them out every two months works best for me. I try never to run out of them even if I have to buy a single filter elsewhere occasionally.
