I have been using these filters for many years. Sam's Club is the most economical way to purchase them using Instant Savings.

Honestly I've been using these for years. The filters are work great! Love the ability to buy in bulk.

It is awesome way to take care of unwanted pollution, germs, and viruses. Change it, as suggested, let it do its function, feel the results.

So far, they have worked really well with my existing AC system. In fact they have cut down the dust in my house by a big margin

Excellent filter! You will have to change it out more often, but I feel it is worth it. And at this price, the price per filter is excellent!

Best price I've found for these ultra filters. Colds and flu are much decreased since starting to use these filters. Dust is minimal (for Nebraska). Would recommend it someone in your family has pets or allergies.

They fit the opening OK and seem to work fine. I can't tell by using them if they do or do not capture allergens, bacteria and viruses.

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 are great. We switched out after six months and it was disgusting to see the collection of dust particles. Great to know it wasn't in the air we breathe.

We have used the Filtrete air cleaners in our a/c and heater for many years and have been very happy with them. They will easily make it two months without replacing, but we choose to replace them every month.
