They work great and it’s cheaper to buy them in a set than individually because they are cheaper in a set

These are made with a much sturdier frame holding up better to installation and moisture. Like anything 3M seems so much better quality overall.

Love that Sam's Club sells a multipack of these filters. Usually can find them in single or double pack at other places.

Have been using these filters for past 6 years. Very durable and helps with allergens. Price better than any other place that I can locate.
