Air Knight PX5

The in-duct unit of the MicroPure family, and the one the founder runs in every air-conditioning unit at home. Instead of waiting for air to reach a filter, it sends active purifying molecules out through the ductwork, treating the air and the surfaces in the rooms the system serves.

Air Knight PX5 in-duct purification unit
MicroPure family · in-duct active air and surface purification · installed inside the air-conditioning by Saniservice
  • Type · in-duct active purification, mounted inside the HVAC system
  • Reach · the air and the surfaces of every room the system serves
  • Technology · UV light on a metallic catalytic core, generating ionized hydroperoxides
  • Power draw · roughly 13 to 19 W across the family, by unit size
  • Operation · continuous, 24/7, and completely silent
  • Servicing · UV lamp about every 2 years, catalyst core about every 4

The technology descends from photocatalytic research developed for NASA's space station program. Inside the unit, a UV lamp shines on a metal catalytic core, and the reaction releases ionized hydroperoxide molecules into the moving air, active scrubbers that seek out bacteria, viruses, mold and odors rather than waiting for them to drift past.

Because those molecules travel with the airflow, they keep working in the rooms themselves: on the air between air changes, and on the surfaces room air never carries back to a filter. That is the half of the job a recirculating machine cannot do.

Description

Photocatalytic ionic oxidation, from UV lamp to living space:

  • Generation. A UV lamp illuminates the coated metal catalytic core, producing ionized hydroperoxide molecules from the humidity already in the air.
  • Distribution. The air-conditioning carries those molecules through the ductwork into every room with a vent, and onward to spaces air movement reaches indirectly.
  • Neutralization. The molecules break down bacteria, viruses, mold and odor compounds at the source, in the air and on surfaces, then revert to ordinary components of air. The technology is laboratory tested against the MS-2 bacteriophage, a standard surrogate for viruses such as influenza.
  • Filtration assist. Ionization also makes fine particles clump together, so the existing HVAC filter catches more than it otherwise would.

It is an active system, not a filter: it does not remove a hidden mold source, control humidity, or clean settled dust. The founder pairs it with a recirculating air cleaner, and with the air-conditioning itself kept properly clean underneath both.
