Purity

The Ultimate Whole-House Air Purifier

 

Purity offers the ultimate enhancement to indoor air quality. The system includes a MERV 11 filter, germicidal UVC light, and photocatalytic media. These three proven technologies actively reduce all types of airborne  contaminants. Purity is attached to your central air system (furnace or air handler) and  purifies the air throughout the home.

What Purity Does

3 Levels of Protection

2. Germicidal UV Light

The UVC light inside Purity sterilizes biological contaminants such as mold, bacteria, viruses, allergens, etc. in the air as they pas through the system. UV light also reduces microbial growth on air system interior surfaces.

3. Photocatalytic Media

UVC light shining on this specially prepared filter media  creates a photocatalytic effect which captures volatile organic compounds (odor molecules) and transforms them into harmless water vapor and carbon dioxide.

1. UV Reactive Filter

This efficient MERV 11 filter media kills germs with Goldshield™ antimicrobial nanotechnology and works with the UV light to trap and destroy microbes. Special filter material will not degrade from exposure to UV light.

Kill Airborne Germs

Biological threats like mold, bacteria, viruses, and allergens can be spread throughout the home by the central air system as it continuously cycles the air. Purity takes advantage of this cycling air to sterilize microbes as they pass through the system.

Indoor Air Quality

According to the EPA indoor air pollution is often five times worse than outdoor and represents a significant health risk. Mini UV improves indoor air quality by fighting odors/VOCs and sterilizing mold, bacteria, viruses, and allergens from the air as it cycles through the central air system.

The Whole Pie

Airborne contaminants can be divided roughly into thirds: particulates, biologicals, and odors/VOCs. Even a high efficiency filter will only capture particulates. Only Purity addresses all three.

No Worries!

We are so confident in the quality of our design and manufacturing that this product comes with a lifetime warranty on all parts except the UV lamp and filter media which need to be replaced every year.

Odor Control

Let's face it, no one wants visiting friends or family to smell the cat box or last night's garlic sauce. You could use a spray or a candle but those things just perfume the air. Purity actually removes odors by transforming odor-causing VOC molecules into harmless water vapor and CO2. So keep the cat, and fry that fish!

How Purity Works

Purity RFM filter captures particulates

Particular About Particulates

Purity's four inch UV Reactive Filter Media does a great job of removing dust and particles from the air, including things like pet dander. These filters not only have a high efficiency rating (MERV 11) they are specially designed to be resistant to UVC light exposure  which most filters are not. In addition Purity RFM filters are coated with GoldShield, an antimicrobial surface treatment used by hospitals on blankets and curtains to reduce infection.

UV light scrambles microbial DNA

Germ-Killing Power of UVC Light

For over a century scientists have known about the germ-killing properties of UVC light. Because this frequency of light is filtered out by the Earth's atmosphere microorganisms have no defense against it. It works by scrambling their DNA which prevents them from reproducing.

DNA Scramble

UVC light works by penetrating the cell walls of microorganisms and scrambling their DNA. This prevents them from reproducing.

UVC light kills nearly all biological contaminants including:

Photocatalytic Oxidation

Purity detoxes the air with a process called photocatalytic oxidation (PCO), a technology similar to the catalytic converter on your car’s exhaust. UVC light reacts with titanium dioxide infused into the carbon which effectively disintegrates the captured contaminants, leaving only harmless water vapor and CO₂ which are released back into the air. The result is clean, odor-free air throughout the home.
