I have just changed the filter so I can't say anything about the filter yet. I did have directions that were easy to follow. I had no difficulty installing the filter

'These seem to be working well this summer. I bought them as a trial from 2800 after the HVAC tech suggested an easier way for the air to flow. So far I really can’t tell a difference except it’s better on my cash flow.

Been buying these filters for a while, they work perfectly in our house and really help eliminate odors, dust and other issues. Price is great when on sale and we stock up on them. Would definitely recommend them.

I've used these filters before, and they seem to work great. I've not noticed and issues with the HVAC system. Sams Club are much less expensive than most other retailers for the same filter.

Excellent whole house filters that don’t degrade under heavy air flow as others I’ve tried. A bit pricey, but worth it the peace of mind and allergen reduction.

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

We have people in our house with allergies and asthma. These filters have proven to clean the air from our HVAC better than others we've tried. The sale price at Sam's is the best value we've found.

Great price, especially when on sale, and worth buying four at a time. I've purchased in the store as well as having them shipped and they arrived in great condition.

I have to buy filters and replace once every couple of months due to my dogs and this is the cheapest place to find them. They are almost $20 any where else.

Nice filters. We buy them when they are on sale. The multi pack is a better deal than buying them individually. They work great! We change them monthly during high allergy times. Can go longer at other times.
