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.

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.

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

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!

The size printed on the filters I bought were not true to size. They were too large and we could not get them to fit. I took them back and bought filters at Home Depot. Perfect fit.

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.

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!

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.

These filters work very well & keep my house & vents very clean! No allergies either & priced a bit high but lower than at other places. I date them & change every 3 months. Once I vacuum cleaned them to reuse once and they held very well for over 6 months!
