VIGILAIR® systems are powered by low pressure mercury lamps that are specifically designed to function inside HVAC systems.

Independent testing comparing our system lamps to the lamps of 15 competitors concluded:

• VIGILAIR® lamps emit 3 to 4 times germicidal UV energy vs. competitors
• VIGILAIR® lamps are more effective than competitors at lower temperatures (45°F-55°F) seen in HVAC systems

Q: Why are these lamps we use more effective?

A: VIGILAIR® lamps are designed and patented for use in HVAC. Many competitors' lamps are designed for use in ambient room temperatures or are derived from designs used in water purification. Our sole focus on HVAC application of UVGI gives VIGILAIR® the power to out perform.
