Air Filters

The cabin air filters are typically a pleated-paper filter that is placed in the outside-air intake for the vehicle's passenger compartment. Some of these filters are rectangular and similar in shape to the combustion air filter. Others are uniquely shaped to fit the available space of particular vehicles' outside-air intakes. Being a relatively recent addition to automobile equipment, this filter is often overlooked

Volatile organic compounds

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

VOCs are emitted by a wide array of products numbering in the thousands. Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbonless copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions.

Hepa Air Purifier

Hepa Air Purifier is a device which removes contaminants from the air. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. Commercial grade air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries.

HEPA stands for "High-Efficiency Particulate Air". A HEPA filter is a type of air filter that satisfies certain standards of efficiency such as those set by the United States Department of Energy. By government standards, an HEPA air filter must remove 99.97% of all particles greater than 0.3 microns from the air that passes through.

Indoor Air Quality

IAQ (Indoor Air Quality) can be affected by microbial contaminants (mold, bacteria), gases (including carbon monoxide, radon, volatile organic compounds), particulates, or any mass or energy stressor that can induce adverse health conditions. Indoor air is becoming an increasingly more concerning health hazard than outdoor air. Using ventilation to dilute contaminants, filtration, and source control are the primary methods for improving indoor air quality in most buildings.

Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces and computer modelling of air flow inside buildings.

Air Filter Purifier

A particulate air filter purifier is a device composed of fibrous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air. A chemical air filter consists of an absorbent or catalyst for the removal of airborne molecular contaminants such as volatile organic compounds or ozone. Air filters are used in applications where air quality is important, notably in building ventilation systems and in engines.

Filter for Smoking

The World Health Organization considers smoke-free laws to have an influence to reduce demand for tobacco by creating an environment where smoking becomes increasingly more difficult and to help shift social norms away from the acceptance of smoking in everyday life. This can be eliminated by using  filters for smoking in Designated Smoking Areas as people do smoking UAE. Along with tax measures, cessation measures, and education, smoking ban policy is currently viewed as an important element in lowering smoking rates and promoting public health. When correctly and strictly implemented it is seen as one important policy agenda goal to change human behavior away from unhealthy behavior and towards a healthy lifestyle.

Indoor Air Quality

People are supposed to inhale clean air to lead healthy life. A lack of ventilation indoors concentrates air pollution where people often spend the majority of their time. Indoor pollution fatalities may be caused by using pesticides and other chemical sprays indoors without proper ventilation. Worldwide more deaths per year are linked to polluted air  than to automobile accidents.Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies.The health effects caused by Indoor Air Quality may range from subtle biochemical and physiological changes to difficulty in breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics.
