Q:

I have allergies and have a good filter in my HVAC unit. The AC company is trying to sell me a UV light for my air handler to purify my air further. I'm very skeptical, but would like your thoughts. Also, is air duct cleaning at all helpful? Thanks

A:

Thank you for your recent inquiry.

There are no data to support the practice of duct cleaning as far as allergen environmental control is concerned, and an ultraviolet filter would not be helpful for aeroallergen filtration.

Thank you again for your inquiry and we hope this response is helpful to you.

Sincerely,
Phil Lieberman, M.D.
