Best filters I have found for our home. Very pleased with them. You should change your filters every 30 days, however, I have gone 6 weeks with these and still had good filtration and flow.

The best when it comes to necessary for the home. Living in Florida where we have lots of allergens, and especially during dry seasons, we all want the best filter available for our homes.

These filters made my furnace not be able to breathe. I had to call a technician to come to my home and it cost me $254 for him to tell me that I needed different filters.

Great to see these in side the Sam's Club store considering that are a very pricey piece of equipment wherever you go. Therefore seeing then in bulk only helps the customers.

I usually buy the filter with less coverages, because I do not need the additional coverages, so I had to spend more money. My income is limited. I believe you should have more than one option to choose from.

Just in time for the start of our spring allergy season as I clean the tree pollen off of the car. I typically use the dust grade until the allergy season arrives. These are an excellent upgrade to capture finer allergens.

Fair price and high filtration. We change the filter at the start of every new season so four will last one year. They are well made and indeed do the job.

Product is super, packaging was perfect. The FEDEX delivery left slot to be desired. The tracking process reported as on truck in area on Wednesday. The order was "out for delivery" on Thursday, Friday, Saturday and finally delivered on Sunday.

Great Filters to use, our service guy said we could go up to 3 months before changing them out with good filters. We change them every 4 - 6 weeks but knowing we could go longer using a good filter is good to know.

Great price on a great product. We have a couple of rescue dogs that shed. That means I always have a need to change my filter often and to always use a good one. This fits that perfectly.
