Nikken Air Wellness Technology is a comprehensive system that combines several mechanisms for purifying and treating air. These include:The filtration systems in Air Wellness Technology are designed to reduce the contaminants identified as being common irritants in the enclosed spaces created by modern structures and contemporary levels of pollutants.The ultra low penetration air or ULPA filter in the KenkoAir Purifier has been thoroughly tested and is certified to reduce these contaminants at performance levels higher than other technologies available in in a home air filtration device.The KenkoAir Purifier includes the following filtration methods:Physical barrier/trapA prefilter and filter combination captures dust, pet hair and similarly-sized particles. The prefilter/filter combination is made of long-lasting, reusable material and has two important functions. In addition to serving as primary filtration, it traps larger particles before they can reach the ultrafine end-stage filters.

Activated carbon adsorption filtrationCarbon adsorption is a highly effective means of reducing contaminants. Adsorption is the capability of a solid substance to attract to its surface molecules of gases or solutions with which it is in contact. It differs from absorption, where the material is drawn below the surface, as with a sponge.Highly efficient adsorption occurs when the adsorbent material is selected for the properties that maximize this effect. Charcoal carbon is ideal for adsorption because its irregular shape offers a large surface area.Activated carbon or charcoal is carboniferous material that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. The use of special manufacturing techniques results in highly porous carbon that has a surface area of up to 2,000 square meters per gram.ULPA filterULPA technology is a breakthrough in air filtration — significantly more effective than a HEPA filter, the longtime standard for hospital operating rooms, microassembly clean rooms and nuclear laboratories.

HEPA filtration is rated at 99.97% efficiency on particle sizes as small as 0.3 microns. The new ULPA technology in the KenkoAir provides 99.9995% removal of particles as small as 0.12 microns. No other air filtration system matches this level of performance.The filter removes airborne particles from an airflow by one of three mechanisms: interception, where particles following a line of flow in the airstream come within one radius of a fiber and adhere to it; impaction, where larger particles are unable to avoid fibers by following the curving contours of the airstream and are forced to embed in one of them directly; or diffusion, an enhancing mechanism as a result of the collision with gas molecules by the smallest particles, especially those below 0.1 µm in diameter, which are thereby impeded and delayed in their path through the filter.Filtration of indoor air has been shown to be effective in relieving or preventing a variety of respiratory discomforts.Daily exposure to indoor pollution may be as much as 100 times as high as that of exposure to pollutants outdoors.

This is due in part the increased amount of the day and evening spent inside (up to 90 percent of the total). Reducing indoor contaminants can have a dramatic effect on improving quality of life.

An air purifier circulates air through a filter that traps air-borne pollutants and irritants like dust, smoke and pollen. tristar air purifierA dehumidifier sucks in moisture and reduces the humidity levels in the air, killing mold and microbes that thrive in moisture.autozone air duct cleaner Air Purifier versus Dehumidifier comparison charthoppe's elite on the go gun cleaning kit

Recommended to alleviate allergy by eliminating mold, dust mites and mildew from the air. Contents: Air Purifier vs Dehumidifier An air purifier circulates air through a filter which removes air borne pollutants, like dust or smoke particles, and even pollen, which a dehumidifier cannot. An purifier may prevent mold build-up as it removes the spores from the air. However, because it cannot control humidity levels in a house, excessive moisture can cause mold to return.

The video below deconstructs a humidifier to demonstrate how it works: A dehumidifier's primary function is to eliminate excessive moisture from the air and bring down a room's humidity levels. While this device does not clear or filter air, it does help remove allergens, like mold and dust mites, which thrive in a moist or humid environment. With a humidity level less than 50%, these sources of allergies and asthma wither and die. This is how a dehumidifier works: Two types of dehumidifiers are typically found in the marketplace: warm mist and cool mist. Regardless of mist type selected, both affect moisture level in the air and lower the level of humidity. Mechanical /refrigerative is the most common type and works by drawing moist air over a refrigerated coil with a small fan. Condensed air is collected, and is effective at higher ambient temperatures where the relative humidity is over 45%. Air conditioners inherently act as dehumidifiers. Adsorption/desiccant is special humidity-absorbing material, moving along a belt, which is exposed to the lower-temperature air being conditioned.

Air is reused after being heated to remove humidity, typically at levels of 35% or lower. Electronic dehumidifier uses a Peltier heat pump to generate a cool surface for condensing the water vapor from the air. It has no moving parts and hence is quieter. But it has low energy efficiency and this design is used for smaller humidifiers. Ionic membrane - a specialized type of ionic membrane can be used as an ionic pump to move humidity in or out of sealed enclosures at the molecular level. The device is mainly used in industrial areas with fuel cell, chemical, or water improvement application. Makeshift - Window air conditioner units that operate similar to mechanical/refrigerative dehumidifiers. Makeshift dehumidifiers function by sending its heat exhaust back into the room. The types of air purifiers include: Filter air purifiers, which use a HEPA (High Efficiency Particulate Air) filter or an ULPA (Ultra-Low Penetration Air) filter to circulate air and trap dust particles.

Ionizing purifiers use corona discharge, a small but powerful electrical field which creates and uses oppositely charged particles to collect together and settle out of the air. Ozone generators which work like ionizing purifiers by changing the oxygen molecules in the air into ozone. Adsorbents use an adsorbent material to take care of odors, fumes and chemicals in the air. UV Light which renders some micro-organisms sterile through ultraviolet radiation. Health hazards of Air Purifiers Ozone production is typical for air ionizing purifiers. Ionic air purifiers can produce ozone as an additional feature to eliminate odor. Many air purifiers generate some ozone, and in the presence of humidity, small amounts of nitrogen oxide. The noise level of a purifier can be obtained through a customer service department Maintaining dehumidifiers requires cleaning all its coils and buckets periodically, and also checking these coils for frost, to improve efficiency.

Air purifiers can be maintained by replacing the filter every 6 months. If the humidifier has plates, they should be washed once a week. To clean the plates, take them out of system and place them in the dishwasher or submerge them in the sink.
