1. The cold catalyst will play a catalyst eect in normal living environment without
any external assistance like UV light, sunlight, high temperature or pressure.
2. lt catalyzes the formaldehyde, ammonia, benzene, TVOC, hydrogen sulfide and
other harmful gases to work with oxygen, and then decompose them into water
and carbon dioxide.
3. The cold catalyst itself does not change during the decomposition process, thus
the cold catalyst is long lasting and can be valid up to 5 years.
4. The main ingredients of the catalyst are food and medicine additives.
Therefore,the product is of non-toxic, non-corrosive and non-flammable. It
works under normal condition and produces only water and carbon dioxide.
5. The cold catalyst can be used to deal with formaldehyde, ammonia, benzene,
TVOC, hydrogen sulfide and other harmful gases released by plywood, furniture,
wallpapers, carpets, curtains and bedspreads.

Cellular-Activated Carbon Filter
Anti-bacterial Filte
High Eciency HEPA Filter
Anion Release
Ultraviolet Sterilize Light
Intelligent Air Quality System
Ultrasonic Humidifier
The cellular-activated carbon carries high ecient additives. It has excellent
absorption and dust collection abilities.
The 5-microns filter with antimicrobial agents can eciently kill bacteria in the air.
The precision of the HEPA filter is 0.01-0.03 micron. It is able to eliminate particles
larger than 0.03 micron with the filtration rate of 99.07% or more. Dust, bacteria,
fungi, viruses, allergens and other small and tiny particles are not able to get through
the HEPA filter.
The ionizer releases anions and makes the oxygen in the air electronegative thus
gatheringthe positively-charged particles likefloating dust, bacteria,viruses and smoke.
The particles become denser and can be easily trapped by filters or sink to the ground.
The smaller the particle size, the higher the capture rate. Does not produce Ozone.
A variety of bacteria and airborne viruses can be killed by the 365nm ultraviolet light.
The UV germicidal lamp is used to purify the air and it is able to eliminate odor caused
by smoke and mold. Besides, it also produces a certain amount of negative ions, which
freshens the air in the room.
This unit comes with an intelligent Air Quality sensor , Humidity Sensor and display.
It can automatically adjust the fan speed according to the setting and displays Air
quality: Red (Poor), Orange (Ordinary), Green (Excellent).
The unit comes with humidification function. User may turn on the humidification
function ( especially in a dry weather or heated room) to:
1. Increase air humidity and improve the quality of respiration.
2. Moisturize the skin.
3. Improve human body’s metabolism, relieve tension and fatigue.
4. Eectively remove the musty odor caused by smoke and mold.
