Buying good quality (Merv13) filters of the right sizes in economical 6-packs from Walmart is easy. With three toddlers running in and out and around the house, I need to change the filters regularly, and having them delivered makes it simple.

Same quality as what I had purchased elsewhere paying more. First time buying air filters from Walmart, will repeat.
