Air Purification: Arguably The Best Option For Improving Indoor Air Quality
Posted on June 19, 2012
The more energy efficient your home is, the more it needs whole-house air purification. Airtight, well-insulated houses can accumulate airborne contaminants, irritating allergens and odors, continually recirculating them in your living spaces. The result? Today, home indoor air quality can be many times less healthy than outdoors. While you may reduce exposure to pollution and allergens by avoiding certain outdoor settings and seasons, you can’t avoid going home. Room air cleaners that rely on a passive process treat only individual zones in proximity to the unit, while contaminants and allergens circulate freely. The total volume of air in your house moves through the ducts of your HVAC system several times per hour. A whole-house system, mounted directly in the air path inside your ducts, utilizes this active movement of air to purify your entire home.
Air purification extends beyond just filtration. Here’s how a whole-house system cleans the air you breathe at home:
- As air is conveyed through the ducts, it passes through a high-efficiency filter rated 16 on the MERV scale, capable of capturing airborne particles down to 0.01 microns. The standard in hospitals and other health-care facilities, a MERV 16 filter removes airborne mold spores, pollen, bacteria and dust mites.
- Simple filtration does not kill microorganisms such as bacteria and viruses, however. After blowing through the primary filter, the air passes through an ultraviolet light source incorporated into the whole-house air-purification system. Micro-organisms are destroyed by exposure to germicidal wavelengths of UV light, which is harmless to humans and pets.
- Ultraviolet light energy combined with a screen coated with titanium dioxide generates a photocatalytic reaction that destroys air contaminants in gaseous form. This process removes volatile organic compounds emitted by solvents, paints and building materials, as well as common odors from cooking, pets and other sources.
