Popular Questions


  • 1. How Do I Improve My Indoor Air Quality?

    The AirKnight IPG reduces germs, odors and allergens from the house proactively.  It cleans the air and surfaces through the use of ionized air scrubbers...the same way fresh air is created by nature outside!

  • Which Air Knight Do I Need?

    The general rule is:

    up to 2.5 Ton system uses the 7" IPG w/px5.

    And a 3 to 5 Ton system uses the 14" IPG w/px5.

  • The general rule is: up to 2.5 Ton system uses the 7" IPG w/px5. And a 3 to 5 Ton system uses the 14" IPG w/px5.

    The Air Knight is not an ozone generator and does not generate ozone as a method of controlling odors. The Air Knight’s Ultraviolet bulb does generate a trace element of ozone that is created as a byproduct of the process, but at the same time, breaks the ozone down to create hydro-peroxides and other advanced friendly oxidizers.

  • Does the Air Knight have electrical safety certification?

    Yes. Air Knight has been certified for electrical safety by ETL, the largest NRTL (Nationally Recognized Testing Laboratory) in the world and UL.

  • What does IPG really mean?

     IPG technology stands for Ionic Particulate Gathering system addresses micro fine particulate in the air and also has a positive impact on bio-aerosols and VOC’s which are Volatile Organic Compounds. 

  • What does PX5 really mean?

    The PX5 technology works by utilizing a metallic catalyst containing a proprietary mix of 5 noble metals including Rhodium, Platinum, Titanium, Copper and Silver. Most other manufacturers utilize Titanium and at most two other metals in their core.

  • Is Air Knight PX5 with IPG the best on the market?

    Air Knight’s IPG technology has best in class ion production. Meaning its ability to create positive and negative ions surpasses other products in the market. The IPG technology works by generating the same ions that Mother Nature creates with lightning, waterfalls, ocean waves, and the like. It is Mother Nature’s way of cleansing the air naturally and creating a healthy environment. It is hands down the best available.
