These are good filters. We have 3 long hair dogs in the house so we change the filter every 6 weeks or so. So glad that Sam's Club has them for a sweet deal!

Good value but filter size is just a hair too big for the vent. Had the same problem with our previous house and this brand. Requires bending the filter a little to make it fit. Wish a big company like 3M would cut these to proper size.

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.

The filter catches the dust well

Very good filters at a good price.

How great it was to buy four filters in a pack. They are not flimsy construction like most.

Only brand filter I ever use!

Great to filter and not strain HVAC fan

Great replacement filter at a great price

These filters work great.
