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.

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!

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

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 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

I know HVAC workers will cringe when I say this, but we really like these better than the cheap ones they HVAC workers say to use. I don't think they're a waste of money. Having the pets we have, being smokers, and living in an older house that's hard to keep dust and dirt out these help much better than the cheap ones. Instead of changing the cheap ones 1 or 2 times a week, we can sometimes go almost a month with these

Excellent filters at a really good price! These really eliminate the finer dust and pollen particles in the air in our house in SC. We have noticed a drop in accumulated dust on horizontal surfaces in the house since we switched to these very efficient filters about 8 months ago.

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!
