Focus on indoor air quality


Air is one of the most basic elements of the survival of all living things in the world. Statistics show that an adult needs to breathe more than 20,000 times a day (13-15 kg of air). Equivalent to 10 times times the amount of food an adult needs in a day, or 3 times times as much as water. The quality of air has a very close and direct relationship with human life and health. In modern society, people spend about 90% of their time indoors (at home, in the office or in public places, etc.), while indoor air pollution is 5 times or even 10 times times greater than outdoors. Bacteria, dust, mites, nicotine, harmful gases and so on are constantly released from the building and decorative materials, such as: formaldehyde, ammonia and so on, all these floats will endanger human health. Often lead to premature aging, insomnia, forgetfulness, worse can even lead to asthma, heart disease, lung disease, or other fatal conditions. Indoor air pollution is listed by the World Health Organization as one of the 10 factors that endanger human health.

Improve indoor air through air purification

Air purification can effectively reduce contaminants in indoor air. As a result, a wide variety of air purifiers have emerged on the market, using a variety of purification technologies: from Electrostatic dust collection (ESP) to HEPA filters, from negative ion generators to reactive oxygen generators, from UV germicidal lamps to photocatalyst catalysis. Each technology has its superiority and uniqueness, but also has its shortcomings and defects. Through the following product introduction, as well as a variety of air purification technology or purifier performance comparison, you will find that our air freshener series, take full advantage of the advantages of a variety of different purification technologies, will be cleverly combined or used in the most appropriate occasions, is your best choice for air purification!


Electrostatic Air Cleaners
An electrostatic precipitating (ESP or Plasmas) air cleaner is usually composed of two sections, a charging section and a collection section. The charging section uses high-voltage wires to impart a positive charge to the incoming pollutant particles. The charged particles are then drawn into a secondary electric field, where they are collected on a series of metal plates carrying the opposite charge. Clean air is then re-circulated back into the general air stream. It can capture particles in a range of 0.01 micron to 1 micron. Some advanced types add in a fan to enhance the draw-in efficiency.
Quite effective, removing about 95 percent of bulk dirt and 85% percent of microscopic particles (small to 0.01 microns), and especially effective for gaseous particles.
High-energy efficiency: most of them consume the electricity under 20 watts.
No costly filters to replace: the collection plates can be washed or wiped down.
The main disadvantage of this type of unit is its high cost due to the sophisticated manufacturing technology.
One side effect should be concerned is that it may produce ozone as a byproduct of use, but it is none harm if the ozone emission is well controlled under safety level.
HEPA Air Filtration
HEPA, which stands for High Efficiency Particulate Accumulation, is a highly effective filter originally designed for removing radioactive particles from air. HEPA air filters are made from very tiny glass fibers that are made into a tightly woven paper. This creates a filter consisting of a multitude of very small sieves that can capture extremely small particles, including some biological agents. Once trapped, contaminates and particles are not able to flow back into circulation, due to the highly absorbent pores of the HEPA air filter.
Effective at removing airborne solid and liquid particulate (small to 0.03 microns) with up to 97.7% efficiency.High replacement cost is a real disadvantage to HEPA filters cannot be washed due to being too easily damaged, they must be replaced periodically depending on use, and typically cost very expensive. Because of so dense, they require a strong blower to move air through, racking up higher energy costs.
And they only remove odors trapped in the filter as it passes through the unit.
Negative Ionizers
Most Negative ionizers use tiny, charged wires or needles to create ions (gas molecules with a negative charge) that latch onto airborne particles. The negative ions cause microscopic particles (particulates) floating in a room, that cause some people to have allergic reactions, to clump together and fall to the floor (or other surfaces) where they can be vacuumed up. This is due to an electrostatic charge between the negative ions and other air molecules and particles in the air.
Removes finer particles than HEPA filters or any other type of air purifier available. A fan-type air filter can only filter the air drawn through it, whereas negative ions disperse throughout the room causing particles to drop out of the air.
Well known as itamin A in the air, they also have been shown to help lift mood, alleviate depression and seasonal affective disorder.
Many ionizers build up a coating of dirt inside that makes them stop working after a relatively short period of time.
An effective solution for this problem is to add in fan before the ionizer wires or needles to blow off the dirt while disperse the negative ions more evenly throughout the room.
Ozone Purification
Ozonizer produces ozone by making oxidation. When a molecule of oxygen, O2, is bound via oxidation to a third oxygen atom, it becomes Ozone, or O3, which is an unstable bluish water-soluble gas with a very characteristic scent that is easy to recognize.
With very unstable characteristic, ozone has a strong oxidation, so is widely used in our daily life for deodorization, detoxification, sterilization, maintaining freshness, and bleaching.
Studies shown that ozone is safe and effective if used properly for: 
1. Neutralizing stale and foul odors.
3. Avoiding the growth of fleas and mildew.
4. Killing all kinds of bacteria.
5. Decomposing the poison residual in vegetables and fruits.
6. Maintaining the frozen food fresh.
7. Decomposing toxic gases quickly.
8. Decolorizing water.
Used in indoor air purification, ozone is safe when occurring within FDA standards at a concentration of 0.05 ppm (parts per million). However, with such a low concentration in the air, it doesn’t show apparently effective in killing bacteria even deodorizing. So it isn’t recommended that air purifiers use ozone for indoor air purification.
But there is a different story when ozonizers generate ozone at certain level to effectively eliminate odors or kill bacteria inside a closed space without human beings or living animals in, such as refrigerators, food storage containers, wardrobes and so on.
UV Air Cleaners
UV light air purification products are basically specialized light bulbs that produce UVC light. UV light is a well-known and effective killer of biological organisms, and breaks down many organic gases into their harmless components.
Ultraviolet lights have been demonstrated to be an effective control measure for controlling disease germs for which such control is necessary, like medical care facilities. The use of UV light as an air-cleaning tool in such environments is both justified and desirable.The problem with UV light is the same damage of the destruction of the microorganisms has a chance to occur to humans skin and eyes. Some UV air purifiers without shielding direct ultraviolet light from escaping the inside of the unit lay down a potential danger to hurt the skins and eyes of the users.
Active carbon
Super absorbing and removing smells ability
The active carbon super absorbing and removing smells ability: Efficient active carbon net sponge is just like the sea alga will instantly remove the smoke in the room, formaldehyde, ammonia, carbon monoxide etc, In the meanwhile, will absorb the dusts.No side effects of active carbon have been found.
Photocatalyst Oxidization
Photocatalyst (TiO2) is a semiconductor that has strong oxidation. Shining of light source can stir up oxidation-reduction reaction on its surface, and the surface will release free radicals, at the moment, chain degradation reaction occurs between the free radicals and kinds of contaminant and bacteria each other. And the reaction can realize the functions of air purification, anti-bacteria, anti-dirtiness and deodorization, hydrophilic nature, and so on.
Utilized in air purification, it can efficiently decompose and eliminate many kinds of organic and inorganic materials and gases in the air.
Coated on nickel foam filter, it is efficient for long consumed without declining with the time, and very convenient for maintenance--the TiO2 nickel foam filter can be washed without any destruction of its efficiency.
No side effects of photocatalyst have been found.
