  • Thanks for the cleaning info, I love my PreVent filters as they saved me a lot of time on the roof in the extreme heat last summer. I've found a damp terry cloth rag removes the cotton very well. Thanks for the YouTube videos!

  • I have 2 customer problems that I solved with your products. These are both hospitals. One had a problem with air filters being damaged by moisture being pulled into them by powerful air handlers. The filters were failing prematurely. I sold them your Model IN filters 3 months ago for one of their air handlers. They just ordered more filters for a second air handler. They have seven more air handlers that could use the same filters, so hopefully there will be many more orders for these filters.  The other hospital had a problem with leaves, insects and debris getting into their air intake louvers.  I sold them the PreVent air intake screen, custom sized, to protect their louvers.
