Air Scrubber Plus® With Activepure™ Technology

Protect your family with the highest quality products to reduce indoor air quality risks. Most indoor air purification and filter systems use passive technology to circulate the air in the home through a filtration system. However, this fails to clean surfaces that carry millions of germs, like doorknobs, toilets, kitchen counters, and pet areas. Air Scrubber Plus® cleans and disinfects the air and surfaces of your home, reducing up to 99.9% of surface micro-organisms and 90% of airborne micro-organisms.  Air Scrubber Plus® is a revolutionary new system designed to help eliminate indoor air quality risks by reducing air pollutants, VOCs (chemical odors), cigarette smoke, dust, pollen, mold, odor-causing bacteria, odors caused by pets, and strong cooking smells. In only 30 minutes the proprietary ActivePure™ technology reduces over 90% of the pathogens in the air – which is 50 times more powerful than typical HVAC filtration. Air Scrubber Plus® with ActivePure™ technology cleans, freshens, and purifies the air using specialized germicidal UV light waves along with a proprietary catalytic process that creates enviroscrubbing molecules of oxygen and hydrogen, just like nature’s outdoor scrubbers.

Air Scrubber Plus® with ActivePure™ technology is the latest advancement of a scientific breakthrough originally developed in cooperation with NASA for use in the International Space Station.  ActivePure™ technology is recognized as the exclusive Certified Space Technology by the Space Foundation in its category. The most highly respected labs in the country have tested and validated the effectiveness of the Air Scrubber Plus® filtration system.

EcoBee Smart Wi-Fi Thermostats

Their latest and most advanced model, the ecobee3, builds on their previous successes to provide one of the smartest and most efficient controls on the market. The ecobee3 takes the things you expect from a smart thermostat, namely remote app control and automatic temperature adjustments, and improves them with a cutting-edge remote occupancy and temperature sensor system. With one remote sensor included and support for up to 32 total, it’s easy for your ecobee3 to get all the information it needs to make your home more comfortable and more energy-efficient—no learning period needed!
