Cold Plasma filtration system has unique advantages:

  • actively destroys the protein envelope of bacteria and viruses;
  • eliminates the need for other types of filtration;
  • converts all the radicals in the water and oxygen;
  • forms a strong, directional, volume flow of charged particles and free electrons, so that covers the entire volume of the room (without the aid of the indoor fan);
  • not throwing dust, nicotine, pollen and other particles on the ceiling and walls, and assembles them.

The principle of Cold plasma filters is based on the interaction of multiple electromagnetic paths, a constructive combination of which gives hydroxide ion (HO2-) or hydroxide plasma. This active particle reacts with the protein membrane of bacteria, viruses and destroys it to form water. Similarly, the structure breaks down chemical compounds (toluene, acetaldehyde, formaldehyde), as well as odors and allergens;


The filter blocks and removes harmful chemical compounds and acts as a purifier of odors and gases, as well as destroys bacteria. Solid catalyst, titanium dioxide, incurred in the form of nano-sized particles, has a strong oxidizing properties. Harmful chemical compounds (formaldehyde, ammonia, hydrogen sulfide, etc.) exposed to light are rapidly decomposed into harmless components. The filter can be reused after regeneration exposed to direct sunlight. What is more, it is absolutely environmental-friendly.


Antibacterial coating helps to destroy bacteria, viruses, staphylococci, fungi, and inhibits the proliferation of these microorganisms on the filter. Filter of the cellular structure can capture microscopic particles ranging in size from 0.1 microns, and the degree of purification is 95%.


This filter is produced from a polymer of a permanent magnet and picks up the smallest dust and smoke.
Electret is a dielectric material that, a long time preserving the polarized state after the external influence, which led to the polarization (or charge) of the insulator, and created in the surrounding quasi-constant electric field.
Filter effectively delays the small particles of dust, dust mites, tobacco smoke, animal hair particles and other microscopic particles that cause allergic reactions in humans.
The filter does not require frequent replacement – electret effect lasts up to 5 years of operation.


The filter is made of activated carbon of micro-cellular structure, which absorbs harmful gases such as ammonia and hydrogen sulfide, as well as all the unpleasant odors. The filter has such features as high-speed and high absorptive capacity.

Digital simulation control technology
– Low vibration and low noise
C&H inverter tech. applies advanced digital simulation control technology in combination with consistency analysis and dynamic analysis to design and optimize pipeline of the compressor, including model tests, parameter identification, load identification, effective meta-model, etc so that the operation with low noise can be realized.


Ductless systems are generally more efficient overall. In fact, distribution energy loss in typical forced air systems has been estimated to be as high as 40%, while estimates for energy loss in ductless systems range from 1% to 5%.
Whereas typical systems generally cap out at 18 SEER, ductless systems, most of which are ENERGY STAR qualified, Cooper&Hunter ductless systems can achieve up to 23 SEER, greatly reducing utility bills. Additionally, because indoor environments can be managed by individual zone, less energy is wasted heating or cooling unoccupied areas.
Thanks to their operational efficiency and zoning capabilities, ductless mini splits waste less energy overall and thus have a smaller carbon footprint. Additionally, all of our newer C&H systems use eco-friendly R32 refrigerant, which doesn’t deplete the ozone layer.


Catechin is a natural substance, contained in tea leaves, that has antibacterial effects. Special C&H technology, which significantly increases the efficiency of cleaning the surface of the filter is applied catechin. It inhibits bacterial growth and kills cancer-causing substances, such as staphylococcus, streptococcus, salmonella and others with an efficiency of 95%.
