Simply Defining Health

The latest invention and most advanced air & surface disinfection device in the world.

Eliminates all types of air pollutants that we breathe.

Kills viruses, bacteria, allergens, molds and VOC’s with 99.9% effectiveness.

A technology breakthrough, using a harmless air-cleaning method performed by Mother Nature.

How Does it Work

Wellisair patent technology imitates nature by producing and spreading in the air high concentrations of °OH Radical 24/7 that destroys micro-organisms as small as 0.1μm

What is °OH Radical
(The Air Detergent)

°OH Radical is a highly reactive oxidant that attacks and destroys all types of micro-organisms.

Mother Nature generates this powerful °OH Radical as a form of environment cleansing.

°OH Radical eliminates all types of microbes and air pollutants by either oxidizing their surface membrane or stealing the H atom from their surface spike protein thus forming H2O. No virus or bacteria can survive without its H atom.

Wellisair kills harmful micro-organisms present indoors on surfaces and in the air through the same °OH Radical oxidation process performed by Mother Nature.

°OH Radical is harmless to human, pets and food.

Health Risk Facts

  • Air pollution is among the top 5 environmental health risks in the world.
  • Infectious diseases are transmitted indoors.
  • Spend 80-90% of our life, indoors.

Common air filters even if called purifiers do not disinfect, they only collect dust and other particles from the air.

Wellisair WADU-02 disinfection device
with other off-the-shelf purifiers.

Filter Devices (HEPA)
Standard air purifiers with HEPA and other filtering technologies do not have the coverage and disinfection efficacy necessary for healthy indoor breathing and living. They draw the air in, filter it to a limited degree and send it back out to be breathed and touched again.

Revolutionized the approach of air purifying from “air filtering” to “air disinfection” by replicating Mother Nature’s own harmless method of disinfecting thru emitting high concentration of °OH Radical.

Supplies & Maintenance
