Air purification and the next frontier of smart home comfort

If you were at CES 2016 and had an opportunity to drop by the Keen Home booth you probably noticed a new product on display. That week, we announced the Smart Filter, an exciting addition to the Smart Vent family and the first of it’s kind in air purification. So what exactly is the Smart Filter, what does it do, and why is it important for your home?

You may not realize it, but the air we breathe isn’t necessarily great for our health. From pollens to pollutants, there are a host of harmful particles in the air we breathe each and every day.  In fact, respiratory illness is on the rise in the U.S. According to the CDC, about 1 in every 12 people (approx. 25 million people) has asthma, a 28% uptick since 2001. According to the EPA, poor indoor air quality is a major environmental health problem. While every home HVAC has return vent filters, these do little to ensure the air supplied to the rooms of your home (air traveling through dirty, pollutant filled ducts) is purified.

According to the EPA, poor indoor air quality is the country’s top environmental health problem.

Few solutions address this essential aspect of indoor air purification. Plug-in filtration units have been available for some time, but are costly, bulky, noisy, and limited in their efficacy. With the Smart Filter, we’re bringing effective, high quality, and smart air purification to the most logical location in a home—it’s air vents.

The Keen Home Smart Filter is the only air filter to use cutting edge 3M™ technology specially designed for high air flow. Smart Filters are coated with a special anti-microbial layer and provide advanced filtration against common household contaminants including:

  • Pollen
  • Lint
  • Household dust
  • Dust mite debris
  • Mold spores

The Smart Filter also contains an active carbon layer to remove offensive odors and eliminate common household toxins like benzene, formaldehyde, and trichloroethylene.

Smart Filter refills seamlessly “click” into a Smart Vent’s removable faceplate in seconds. In building this product we set out to create a solution that could be easily added to and removed from our existing faceplates. We originally designed Smart Vent faceplates with this future application in mind--including a channel along the center of every Herringbone faceplate specifically for use with Smart Filters.

Smart Filters fit perfectly into Smart Vent faceplates

Since we’re tech nerds at heart, we are already cooking up different Smart Filter models which could include features like advanced odor neutralization and scent diffusion. Stay tuned for more...
