I'm looking for recommendations and some feedback from someone that has used one. I have asthma caused by allergies.

Thankyou,

My teenage grandson has had asthma for about 5 years and when we had the air ducts in the house professionally cleaned and sanitized, he has improved alot. From a big reduction in sneezing, itchy eyes to preventing the episodes that can lead to worse symptoms. We do not use a home air filter although have a professionally installed hepa filter in the central a/c unit.
