UV LED Air Sterilizing system for Ductless Split HVAC Units with High Formaldehyde Removal Rate

Usage: Commerical or Household Sterilization

Толқын ұзындығы: ультракүлгін-С және ультракүлгін-А

Application: Mini-split air conditioner for bedroom, living room, hotel and other confined space

Degradation formaldehyde rate: 89.1% 

Sterilizing Rate : 99.93% 



Бүгінгі күні, UV LED+Photocatalyst is an emerging and encouraging technology for indoor air purification and decontamination using TiO2 as a catalyst under the illumination of UV LED.

With the technology, all carbon-based organic matter, including bacteria, viruses, smoke, formaldehyde, pollen, mites...(RNA & DNA materials) can be oxidized into CO2 and H2O.

Especially, most people spend more than 80% of their time in closed environments like modern office buildings, hotels, schools, and especially at home, while  indoor pollution is becoming a serious air-quality problem

Сондықтан, UV LED+Photocatalyst technology is becoming a popular sterilization solution.


Apart from viruses and bacterial, UV LED+Photocatalyst can also deal with the formaldehyde (HCHO) problem, which is one of the major species in polluted indoor air.

Formaldehyde (CH₂O) is a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products... It can cause irritation of the skin, eyes, nose, throat, and even cancers.

Formaldehyde levels are higher in:

(1) Homes with smokers.

Smoke contains formaldehyde. If someone in your home smokes, the smoke may be the greatest source of formaldehyde in your home.

(2) Homes with New decoration.

Formaldehyde levels are higher in newly built or newly renovated homes, especially wooden furniture, soft cloth ornament, pain wall.

In general, these products will emit less and less formaldehyde over time. However, it can take weeks, months or even years to stop completely. 

(3) Summeer Time

In summer, the temperature is high, the adhesive has been decomposed, and the decomposed formaldehyde molecules also have enough mobility to diffuse from the inside of the home items.

In summer, the humidity is high, and the water molecules are increased and active, which is easily transmitted to the home items, causing the adhesive to produce more deliquescence, thereby more free formaldehyde.

UV LED sterilization

Traditional methods for removing formaldehyde (HCHO) from the environment including the following ways:

(1) Ventilation

The release cycle of formaldehyde is long, usually three or even ten years to reach the normal standard.

(2) Plant deodorization

If you use plants to remove formaldehyde, you will almost fill the entire house. Moreover, the production of photosynthesis is conditional, but formaldehyde is continuously released.

(3) Activated carbon adsorption:

The adsorption capacity is very limited, it will volatilize again after the adsorption is saturated, and it needs to be replaced continuously for a long time.

(4) Scavenger

When the scavenger is sprayed in the air, it will cause new pollution hazards to people.

UV LED sterilizing solution

To better achieve sterilization effect, we have developed the UV LED+Photocatalyst technology.

(1) UV LED Strip: UVC

UVC will destroy the DNA or RNA of the bacteria&viruses, making them inactive and unable to reproduce.

(2) UV LED Strip: UVA (405nm)

The light-sensitive molecules such as riboflavin in bacterial cells can absorb specific light energy in UVA to oxidize the cells to form active molecules such as OH-, O2-, 02, thereby damaging the cell wall.

(3) 5nm Photocatalyst Filter

Immobilizing TiO2 on an adsorbent material can upgrade and refine the HCHO removal efficiency.

Сондықтан TiO2 / AC желілік пленкасы HCHO тиімді жою үшін белсенді көміртектің бетіне нанометриялық TiO2 бөлшегін толтыру арқылы жасалған.

UVC LED sterilizing process

How does the UV sterilization process work?

1. Tio2 сүзгісі болды сәулелендіреді, бұл фотокатализатордың әсерін тудырады.

2. Фотокатализатор әсерінен күшті тотықтырғыш OH + шығарылады.

3. OH + зиянды заттарды қоршап, жоя бастайды. 

4. All carbon-based organisms, including bacteria, viruses, smoke, formaldehyde, pollen, mites etc, will be disintegrated into H2O & CO2.

5. For harmful substances not killed by TiO2, UV LED (UVA+UVC) will offer supplementary function.

Therefore, the UV LED technology can achieve a 99.93% sterilization rate and 89.1% degradation formaldehyde rate.

why choose UVC LED

Why choose UV LED+Photocatalyst?

(1) Comprehensiveness

Effectively degrade formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other pollutants in the air.

(2) Safety

No UV light leakage, harmless to the human body. The by-products after use are CO2 and H2O, which will not cause secondary pollution.

(3) High Efficiency

Our disinfection system can kill harmful substances immediately to prevent them from repairing structure and activity. The sterilization rate is 99.93% and the formaldehyde degradation rate is 89.1%.

(4) Long Lifespan

 Full inorganic package technology, 10 times longer lifespan. 

(5) Easy to install

Even consumers can install our UVLED+Photocatalyst System by themselves in 5 minutes.
