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

Best Effort with Animals but requires changing monthly or I find dust starting to get inside duct intake

Removes just about everything but the air...works nice and lasts about 3 months, easy to replace. The multipak is a good value.

These are the filters we depend on. Their efficiency is obvious via the dog hair, lint, and dust accumulation after 2 or 3 months.

We know we can find these at Sam's and not have to look all over other places, so we just always get them at Sam's!

Have used both products for a number of years. They both do a great job for there intended use. Both are bought from Sam’s at a good price

I have used this type filter for years and they have done very well in keeping my furnace and air conditioning free of dust.

These work well along with my air purifier to keep dust down in our home. I purchase every January and with a pack of four they last the whole year.

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.

These filters are very good. They are also very very expensive but the convenience of getting them while I'm out is why I buy them.
