HALO Active-Airflow Replacement Filter for HALO Active-Airflow Crib Mattress

Exactly what I wanted and arrived in a timely manner.

I think this is the best idea for mattresses. I wish they were made for adult beds. At first I didn't think the mattress would work, but when I changed the filter I couldn't believe all the dust and dirt that was collected. I am real happy with the mattress and filters. I LOVE THESE PRODUCTS !!!!
