Electrostatic air Filters

Electrostatic air Filters or Cleaners is a particulate collection device that removes particles from air using the force of an induced electrostatic charge. Electrostatic air filters are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream.

A useful device can be used indoor, that traps 97% of all allergens and other airborne dust. Indoor air is healthy and clean which avoids more allergies caused due to indoor air pollution.

Air Filters

Air filters and filtration techniques are used for a wide variety of purposes, some of which include:
  • Improving the occupants breathable environment.
  • Protecting  a facilities walls, ceiling, equipment etc. from air-born particle damage.
  • Protecting the contents of occupied building spaces such as; items of artistic historic or cultural value.
  • Elimination or minimizing fire hazards.
  • Improving shelf life of perishable food products by removing airborne mold.
  • Removing airborne bacteria from controlled environment such operating rooms.
  • Filtering or removing air born particulates which could damage sensitive micro electronic devices within clean rooms.

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.
