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

Have not opened these yet but it is a product I use almost exclusively and is always a good performer.

These filters were supposed to fit but they were too long. I purchased same at Walmart and they fit.

Great filters. Every chance I get I purchase these filters. They really help keep the air free of animal hair and other types of dust.

We have been using these in our home for years. We change them about 2-3 times a year and appreciate this value at SAM's.

Every. Last. Particle. They fit well and seem to have quality construction. Nothing to complain about!

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.

Yellow pollen and pet shedding time is driving my allergies bonkers but it likely would be worse if I was suing the usual filters.

So nice to order from home!!!! Sorry shop, no issues, great products to choose from, this is my style of shopping!

These are great! We found out that my son is allergic to our cat. These filters help a lot! And I have noticed we have less dust.
