We purchased these filters last year and again this year as well. The filters def last 3 mo each so although it seems like a lot of money for a package of filters, you have to remember they last a whole year. When you price these filters individually you realize you save a lot buying a multi pack.

After using this once, I was amazed how much dust and other air debris it caught!!

Great purchase. These filters are very good quality.
