These seem to work very well, there is much dust around the house since we’ve been using these filters

I change my furnace filters every time the season changes. This makes it handy to order a year's worth every spring.

Purchased several times. I like that they are on instant savings from time to time. Good quality filters.

As soon as I installed these filters my wife stopped sneezing. She had been suffering for days. What an endorsement.

My daughter has allergies and these filters work great and really seem to help with the desert pollen

Its just 25 days I used this product. My wife felt a change in dust layers on furniture n felt air more fresh n not muddy smell.

My son an HVAC technician said too high of a rating makes your furnace work harder. This was the only filter I could find that fit my furnace

These are not individually “wrapped” so if you only need one, the others need to be covered with something else.

Great filters and bargain for 4 at Sam’s club price , turned on my neighbor to buy at Sam’s going forward

Excellent filters. Been using these for 10 years. We change every 3 months. Sam’s has the best price especially when on sale. Fast shipping. ❤️
