Great service for many years
It so easy not to replace filter on time
Put schedule that works for you. You’re notified and then shipped.

Quality of this filter as well as the price and delivery makes fitting it easy for a 74 yr woman to install. The size is perfect for a hard to reach ceiling vent. Highly recommend this filter as well as this company.
