Breathe Better, Live Better
The Premium HVAC UV-C Light for a Cleaner Coil and Cleaner Air
A healthier, more comfortable home starts with the air you breathe. BioShieldUV installs inside your HVAC system and runs continuously on the evaporator coil — the dark, damp surface where mould and biofilm grow. Keep that surface clean and your air stops being drawn across a dirty one every time the system runs.

How BioShieldUV Keeps Your Coil Clean
Air Intake
Your HVAC system draws in indoor air for processing through our advanced filtration system.
UV-C Exposure
The lamp irradiates the evaporator coil surface continuously at 253.7 nm.

Your system then moves air across a coil kept free of mould and biofilm, instead of across a dirty one.
