Do In-Duct Air Purifiers have a fan? Is that how they purify the air?
In-Duct Air Purifiers utilize the fan or air exchange unit in your existing HVAC system. This reduces operating cost since it doesnt contain a fan. When contaminants enter your HVAC system and pass over the In-Duct Air Purifiers UV lamp, they are destroyed. Air coming from your HVAC system will have low levels of negative ions and ozone. These will oxidize airborne particulates, eliminate odors, and break down other unhealthy fumes and organic contaminants.
