REME HALO® Whole Home In-Duct Air Purifier
Better life through better air
REME HALO® is more than a conventional UV lamp, not only because of its innovative design, but also because of its ability to actively improve the quality of the air in your home. Most air purification systems are either passive or ineffective at meaningfully reducing pollutants. That’s why the REME HALO® was designed to be something better. Not only does it use UV light, but it also has other advanced proprietary technologies to improve the quality of your air. One of which, sets this product apart through its ability to produce low levels of hydrogen peroxide in the air that circulates through your air-conditioning system and indoor spaces. Throughout your air-conditioned space, REME HALO® reduces bacteria, viruses, odors and mold spores in the air and on surfaces. If you want to feel the healthy difference a REME HALO® can make.

Case Study - Measuring A/C Energy Efficiency

Heating & A/C in a typical home uses 50% of your annual power consumption. It may come as a surprise that air conditioning units naturally lose 10-15% energy efficiency every single year. Without proper maintenance, A/C units will continue to lose efficiency over time.

A $79 annual tune up can save you hundreds off annual energy bills and protect your equipment!

The Myth About Freon Replacement

Some say that A/C systems require more freon every few years, but that’s simply not true. Missing refrigerant signals a leak in your system that should always be professionally located & repaired before recharging occurs.
