Frequently Asked Questions

A UV air purifier system uses the light spectrum to eliminate airborne pollutants such as bacteria, viruses, allergens, and other microscopic particles. Common air filters are not effective in the same way, as they only utilize physical material to filter air. Hospitals and food processing plants often use UV air filtration systems in conjunction with other filters for highly effective air filtration.

UV air purifiers should undergo a yearly maintenance check along with the rest of your HVAC system. They also require regular changes of the physical component of the filter, though how regular will depend on how much your filter is used. For example, if you have pets, their fur and dander may require you to change the filter more frequently.

Ensure that all paths to potential work areas are free and clear of tripping hazards. Have all work areas readily accessible, including your furnace room.

Our expert technicians complete UV air purifier installations in 1 to 3 hours. However, this may depend on factors such as how accessible the work areas are.
