These are good filters. They are good quality and stronger than the cardboard filters. These have a wire mesh on both sides and stay firm and strong with the air flowing through them. They hold a lot of dust and keep the AC unit very clean. Keeps a lot of dust from flowing into the house. Keeps the air cleaner.

I only buy Filtrete, they're the best. Unfortunately my 10 year old furnace died 2 days after I received these filters and I never had a chance to use them. Replacement furnace uses a different size and the company I used provides free filters for 2 years so I will be returning these. Will buy the new size from Sam's when the free filters run out or if I decide the free filters aren't doing the job.

This is a really great deal for filters that need to be changed every 30 days. It gets so expensive when you have to buy them one at a time so I was really happy to find a four pack! They have all sorts of sizes and honestly, you can buy three of them and get by for a whole year!

I’ve been purchasing my furnace filters from Sam’s for a few years now and it appears these filters are much sturdier than those I have purchased in the past. Great upgrade in product and as always, great customer service/support. Thanks, Sam’s Club!

I always buy 3M filters. They feel like they work the best and are well worth the extra money than the plain-jane filters. Not only do we live on a gravel road in the country, we have 2 dogs that are inside/outside and shed. I also have some allergies, These filters help tremendously!

I have tried cheaper brands but I always come back to filtrete. They have different merv ratings for different situations. I have Saint Bernards and lots of dog hair and dander and it takes care of it all.yes they are expensive but worth every penny.

The Filtrete Ultra Allergen Bacteria and Virus filter seems to be helping reduce my allergies, especially when used in combination with room air purifiers. The MERV rating of 12 is higher than I usually prefer since it can restrict airflow, but these filters make it worth having my A/C work harder throughout the day. They offer great value when purchased in a pack of four, and Filtrete is a leading brand in air filters.

These are the best filters we found at any store, including the local hardware stores. We wait for them to go on sale, and usually buy two packs, as we change our filter every month. Thus far, we feel that these filters are helping to keep our furnace cleaner and our air clean. Definitely recommend.

They were received in good condition from the shipping company. We use these filter because I have a severe respiratory condition, These filters help keep down microscopic particles that could exacerbate my condition. In my option they are excellent filters.

Filtrete is a very good filter. Traps the pollen this time of year. I have a dual heat pump that has different Returns and the settings. One upstairs and one downstairs in the ceiling. I also have a larger return in the Den. All work well with Filtrete filters. Rarely have to dust!
