Air Purifiers

Get healthier air for your home with the following air purification products:

PHI Cell

The PHI CELL Advanced Oxidation Systems is designed to help eliminate sick building syndrome risks by reducing odors, air pollutants, and cold and virus causing germs through a patent pending Photohydroionization® (PHI) process. The PHI Cells are easily mounted into existing air conditioning and heating systems. When the HVAC system is in operation, the PHI Cell uses an Advanced Oxidation Process to reduce the airborne contaminants.

Air Purifier

The Air Purifier is a premier air purification solution. It’s ideal for homeowners with allergy concerns, those susceptible to airborne germs, such as infants and the elderly, and those sensitive to the effect of molds, pollen, pets and more.

  • The Air Purifier offers extremely high air filtration efficiency and patented germicidal technology so effective it even captures and kills airborne pathogens such as bacteria, viruses and mold.
  • The Air Purifier uses the same exclusive technology trusted to protect secure government facilities and hospital room patients.
  • Unlike many portable air cleaners, the Air Purifier is extremely quiet and can treat the air throughout your entire home. In fact, the Air Purifier cleans over 100 times more air than some of the popular portable units.
  • The Air Purifier is as convenient as it is powerful because no cleaning is required. Simply remove and replace the media cartridge periodically to maintain peak performance.
