These werk great at filtering out the air. This brand is always sturdy & doesn't get warped or pulled into the unit like some of the cheaper made ones.

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.

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 filters are the best I have used. They get pet hair, dirt and dust although I have cats and dogs so I actually change my filter every month but it does cut down the dusting

You normally save a lot when you buy in bulk but this is not one of those moments. It’s about the same price at H-E-B. And we normally get a higher rated filter

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.

We've used lower rated Filtrete filters that work well. I bought the Ultra because the others were out of stock. If you buy any Filtrete filters, I recommend changing them before your system shuts down from lack of air flow. They are that good!

I only buy Filtrete, they're the best. Unfortunately my 10 year old furnace died 2 days after I received these filters and I never had a chance to use them. Replacement furnace uses a different size and the company I used provides free filters for 2 years so I will be returning these. Will buy the new size from Sam's when the free filters run out or if I decide the free filters aren't doing the job.

These are the best filters we found at any store, including the local hardware stores. We wait for them to go on sale, and usually buy two packs, as we change our filter every month. Thus far, we feel that these filters are helping to keep our furnace cleaner and our air clean. Definitely recommend.

I own an older home. My HVAC air return is an odd size. Can never find it at other retailers. Its always in stock online and at a better price with Sam's. I place my order and 2 or 3 days later the box is delivered to my front door! No shipping charges since I'm a plus member!
