I was asked to find new filters for our energy recovery ventilator at church. This was the best price and delivery on line and much better than the local HVAC house

Item replaced existing filters perfectly.

All products ordered from iaqsource.com have always shipped fast and arrived in perfect condition. They receive my highest recommendation.

Living in dusty Eastern Washington the whole house air system with the Hepa filter spares me from allergies, but stick to the schedule or air movement becomes constrained.

We own and ICF home and an air exchanger is a must as the home is too efficeint.

For my allergy control works realy good.

This product was easy to install.

Pet dander filled home, autoimmune occupied owner. This system keeps air fresh (combined w/ air-air heat exchanger).

I've ordered several of these over the past few years all have arrived as ordered, worked well and are priced fairly.

The filters for the whole house air systems are not cheap but they cost even more locally through heating and a/c dealers. [...] they were the correct ones for my system. Very satisfied.
