We have a central HEPA system and Need a new air exchange machine. Venmar won't help me. Our home is in the south humid, I'm not well, the Venmar was installed in the condition crawl space. Our home is 1800 square feet. I was told you need an air exchange machine for the HEPA to help. Please let me know what to get in Virginia?
