Airdow Air Purifiers

ADA Air Purifier & Air Cleaner (Xiamen) Co., Ltd. has been a manufacturer of Airdow air purifiers and air fresheners since 1997. Their products are of excellent quality and safety and are guaranteed by international approvals and standards. This level of quality enables their products to be sold in over 30 countries worldwide.

After 10 years of research and development in the field of air purification, Airdow has mastered the integration of various purification technologies in order to produce air purification systems that cater for many different indoor environments and specific air purification needs. They combine proven technologies such as HEPA filters, carbon filters, TiO2 photo-catalyst filters, negative ion generators and exclusive O.F.S. antibacterial technology.


1. Prescreening filter
This sponge filter’s main function is to capture large particles such as dust, pollen and skin flakes. This shields and protects the life of the other filters.
Life expectancy of replacement filter: 3-6 months, depending on the environment.


2. HEPA filter (High Efficiency Particulate Air filter)
Originally developed by the Atomic Energy Commission, it removes 99.97% of particles down to 0.3 microns in size, almost 300 times smaller than the width of a human hair. HEPA technology is currently the only type of air purification tool recommended by the U.S. Government’s Department of Homeland Security.
Life expectancy of replacement filter: 3-6 months, depending on the environment.


3. Activated carbon filter
This particular filter captures and neutralizes common chemicals, gases, odours and tobacco smoke with the highly absorbent micro-pores in its matrix.
Life expectancy of replacement filter: 3-6 months, depending on the environment.


4. Advanced O.F.S. filter (Organic Fibre Sterilization)
The O.F.S. technology has proven to have broad spectrum antibacterial effects and can restrain growth and reproduction of airborne bacteria, mould and fungi. Test results prove that the O.F.S. filter can kill up to 97.97% of airborne bacteria in a room after 6 hours of operation.
Life expectancy of replacement filter: 3-6 months, depending on the environment.


5. UV/TiO2 Photo-catalytic filter
This advanced anti-bacterial technology utilizes a titanium dioxide (TiO2) photo-catalyst filter that when irradiated by photons emitted by a UV lamp releases hydroxyl radicals and super-oxide ions.
These highly reactive particles oxidize harmful volatile organic compounds, as well as kill and decompose air-borne bacteria, viruses and fungi. This process is referred to as photo catalytic oxidation.

Life expectancy of replacement filter: 3 – 6 months, depending on environment.
Life expectancy of UV lamp: 9 – 12 months, depending on usage.
6. Negative Ion output
This feature can be turned ON/OFF at anytime and is available on most units.
The negative ion generator acts as a dust precipitator system by releasing millions of electrically charged particles into the air which cause dust and other harmful air particles as small as 0.01 microns to settle, effectively removing them from your breathing space.
Negative ions offer many more fantastic and well documented physical and mental benefits.

They have been shown to counter-act the effects of cigarette smoke, improve mental attitude and concentration, have the same effects as anti-depressants like Prozac and Zolof without any negative side effects, improve sleep and help with insomnia, relieve migraines and much, much more.

Life expectancy of Negative Ion Bristles: 5 years
