PURIFIER FEATURES:
Cold Catalyst Filter:
1. The cold catalyst filter provides catalyst effects without any external assistance such as sunlight, UV light, high

temperature, or pressure.

2. The cold catalyst filter catalyzes formaldehyde, ammonia, benzene, TVOC (Total Volatile Organic Compound),

hydrogen sulfide, and other harmful gases to work with oxygen, and then decomposes them into water and carbon

dioxide.
3. The cold catalyst filter does not change during the decomposition action, thus it is long-lasting and can be used for

up to 5 years.

4. The cold catalyst filter is non-toxic and non-corrosive.
5. The cold catalyst can be used to deal with formaldehyde, ammonia, benzene, TVOC (Total Volatile Organic

Compound), hydrogen sulfide, and other harmful gases released by plywood, furniture, wallpapers, carpets,

curtains, and bedspreads.

CELLULAR-ACTIVATED CARBON FILTER:
The cellular-activated carbon carries high efficient additives. It has great absorption and dust collection characteristics.
Ultraviolet Sterilizing Light:
The 245nm ultraviolet light kills a vast range of bacteria. The UV germicidal lamp is used to purify the air and is able to
eliminate odor caused by smoke and mold. It also produces negative ions, which freshens the air in the room while avoiding
the spreading of certain viruses.

HUMIDIFIER:
The unit includes an optional humidifier function that can be turned on during dry weather to:
1.  Increase air humidity and improve respiration.
2.   Effectively remove musty odors caused by smoke and mold.
3.   Moisturize skin.
4.   Improve the body’s metabolism and relieve tension and fatigue.

PROPER CLEANING OF FILTER
1. The filters should be exposed to direct sunlight periodically. (NOTE: this allows the filters to release gases, odors,

and bacteria).

2. Do not place the filters close to heat to avoid distortion and/or fire.

FUNCTION DESCRIPTIONS

speed. (NOTE: the speed and sleep buttons are mutually controlled – when one is turned on, the other is turned off).

6. Pressing the anion button turns on the anion generator as well as the intelligent odor sensor control, and the anion

icon lights up on the display screen.

7. Pressing the sterilize button turns on the UV germicidal light as well as the intelligent odor sensor control, and the

sterilize icon lights up on the display screen.

8. Pressing the humidify button turns on the humidifier as well as the intelligent odor sensor control, and the humidify

icon lights up on the display screen.

9. Press the mist button to adjust the mist amount from low to medium to high.

HUMIDIFIER FUNCTIONS

PROBLEM

SOLUTION

No air is coming out from the outlet

Make sure the product is connected to the power outlet and turned on.

Outlet air flow has significantly weakened

The filters may be dirty and need to be cleaned or replaced. You can lightly shake the filters to remove dust

Make sure the filter packaging bags are removed

The air quality has not improved after long time use of the machine

Check the filter layers sequence; they may be in the wrong order

The filters may be worn and need to be replaced

When should I replace each filter?

(Exact filter life depends on the air quality of the environment and the duration of use)
First filter: The surface will become dirty and faded in color. The tiny hole of the cold catalyst may be blocked by dust and
the color of the activated carbon may have changed.
Lifetime: 8-14 months

Second filter: The white HEPA filter may change to yellow or black, and you may see mildew.
Lifetime: 8-14 months

Alarm is sounding

The water tank may be empty

The machine powered down
