I've been in the HVAC Industry for over (40) years. This filter is Great for Newer units with Variable Speed Motors. It isn't Costly plus it supplies Excellent filtration & Air flow for my unit.

Product is great and service is great! However, you send too many emails for sales. After I place an order, I keep receiving more advertising emails. When I purchase from your company, I’m satisfying my need for the next year. I love your product and company, but please find a way to back off on the advertising, especially after an order has been placed and received. Thank you.

This is an old house that is prone to being dust-laden--no matter what I do--too many leaky windows and doors. At the onset of installing the Health Filters I noticed a dramatic reduction of the amount of dust blowing from the AC vents! And that is very important for my COPD issues!
