Only Brand We Use

Like the title says, we always purchase our filters from Filter Buy. We've been purchasing them for many years and hope to continue into the future. They do a great job of filtering out pet hair, dander, etc. Living in Arizona, it's very important we have good filters due to our dry dusty air.

Filter is constructed very well. Catches a lot of stuff in the air. Being yellow makes it easy to tell when you need to change.
