Shipped on time and in good shape.

Captured tons of particles.

Been using these for several years, good filter.

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

Definitely the best ones to use if you have a compromised immune system.

They seem to do a very good job

Good filters. Reasonably priced.

Best Brand to buy for your furnace

Good filters and good price!

Perfectly constructed & better in bulk!
