A guide to understanding air cleaning terms:

• ACTIVATED CARBON or AC: Activated carbon is the generic term used to describe a family of carbonaceous adsorbents with a highly crystalline form and extensively developed internal pore structure. Activation creates a fast internal pore network and imparts certain surface chemistries (functional groups) inside each particle. Thus activation gives carbon its unique filtering characteristics.

• CADR: Although there is no universally accepted method for comparing air-cleaning devices, several investigators of portable air-cleaning units have expressed their results as a "Clean Air Delivery Rate" or CADR. The CADR is the product of the unit efficiency and the airflow rate, and is a measure of the number of CFM of air it cleans of a specific material.

• CARBON: Carbon, the sixth most abundant element in the universe, has been known since ancient times. Many natural substances of base materials are used to make carbon. The most common of these are wood, coal, lignite, and coconut shell.
  Amorphous carbon is formed when a material containing carbon is burned without enough oxygen for it to burn completely.

• CLEANING CAPACITY: An air cleaner must constantly recirculate indoor air in order to effectively reduce concentrations of airborne particulate contamination. Cleaning the total volume of air contained within a room is the equivalent of completely changing the air in that room. Air cleaner filtration capacity is expressed as the number of air changes per hour (ACH). For air cleaners of equivalent filter effectiveness, a higher ACH rating yields higher levels of air quality improvement.

• DOP: The DOP Military Standard is the standard set by the federal government to rate particle reduction by HEPA filters. This test rates high-efficiency filters by the percentage of 0.3 micron size particles of dioctylphthalate (DOP) smoke they remove.

• ELECTROSTATIC: Electrostatic units filter the air using static electricity have a static charge on the filter to allow airborne particles to "stick" to the filter, just like static-charged clothing sticks together.

• GAS ADSORPTION: When a gas or vapour is brought into contact with a solid, the solid takes up part of it. The molecules that disappear from the gas either enter the inside of the solid, or remain on the outside attached to the surface. The former phenomenon is termed absorption (or dissolution) and the latter adsorption.

• HEPA Filter: HEPA stands for High Efficiency Particulate Arrested Filter, and like the name says, these filters are designed to remove 99.97% of all airborne pollutants 0.3 microns or larger from the air that passes through the filter (these include tobacco smoke, household dust and pollen).

• IONIZER: Ion generators act by charging the particles in a room so that they are attracted to walls, floors, tabletops, draperies, occupants, etc. Abrasion can result in these particles being resuspended into the air. In some cases these devices contain a collector to attract the charged particles back to the unit. While ion generators may remove small particles (e.g., those in tobacco smoke) from the indoor air, they do not remove gases or odours, and may be relatively ineffective in removing large particles such as pollen and house dust allergens. Although some have suggested that these devices provide a benefit by rectifying a hypothesized ion imbalance, no controlled studies have confirmed this effect.

• MICRONS: A micron is a unit of length equal to 1 millionth of a meter or .000039^th (39 millionth) of an inch. Another name for micron is micrometer.

• MOULD SPORES: Moulds produce tiny spores to reproduce, just as plants produce seeds. Mould spores waft through the indoor and outdoor air continually. When mould spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are moulds that can grow on wood, paper, carpet, and foods. When excessive moisture or water accumulates indoors, mould growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. Moulds can trigger asthma episodes in individuals with an allergic reaction to mould.

• OZONE: Ozone, a lung irritant, is produced indirectly by ion generators and some other electronic air cleaners and directly by ozone generators. While indirect ozone production is of concern, there is even greater concern with the direct, and purposeful introduction of a lung irritant into indoor air. There is no difference, despite some marketers' claims, between ozone in smog outdoors and ozone produced by these devices.

• OZONE GENERATOR: Ozone generators that are sold as air cleaners intentionally produce the gas ozone. Often vendors of ozone generators make statements and distribute material that lead the public to believe that these devices are always safe and effective in controlling indoor air pollution.
  
  Some vendors suggest these devices have been approved by the federal government for use in occupied spaces. To the contrary, NO agency of the U.S. federal government has approved these devices for use in occupied spaces. Because of these claims, and because ozone can cause health problems at high concentrations, several U.S. federal government agencies have worked in consultation with the U.S. Environmental Protection Agency to produce this public information document.

• PRE FILTER: A pre filter is the primary layer of filtration that collects large particles before they reach the HEPA filter. Eliminating these larger particles, dust and hair extends the life of your HEPA filter. Occasional vacuuming of the exterior of the unit will help extend life of the filters. Frequent pre filter changes will also prolong the HEPA filter life.

• PRECIPATATOR: There are many simple electronic devices that claim to clean the air in your home by making negative ons and ozone. The claim is accurate-they do make both ozone and negative ions, and they do clean the air in your home. However, that's not the whole story. First, ozone may have the "fresh" smell that occurs after a thunderstorm (a potent producer of ozone), but ozone is a powerful oxidizing agent and chemical irritant that's considered an environmental pollutant rather than a charming scent. The manufacturers are taking a nuisance effect and touting it as a "valuable feature." Second, the negative charges emitted by these electronic devices attach themselves to dust, ash, pollen, and smoke particles and cause those particles to bind themselves to your walls and furniture. The air really does become cleaner, but every surface in your home becomes dirtier as a result.

• PM10: Particulate Matter Up to 10 Microns in Diameter (PM10). The number 10 refers to the particle size measured in microns. PM 10,s are widely considered the most dangerous to human health.

• 3 SPEED: 3-Speed refers to a variable speed selection control on your air cleaner. This control allows you to operate your air cleaner on low, medium or high settings depending upon your needs.

• PARTICLE COUNT: A standard developed for measuring particulate matter in a pre defined area.

• RPM: Revolutions Per Minute (RPM) is a measure of speed for any rotating device. Typically round in specifications for motors.

• SICK BUILDING SYNDROME: The term "sick building syndrome" (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified. The complaints may be localized in a particular room or zone, or may be widespread throughout the building.

• The following have been cited causes of or contributing factors to sick building syndrome:

  • Inadequate ventilation: Inadequate ventilation, which may occur if heating, ventilating, and air conditioning (HVAC) systems do not effectively distribute air to people in the building.

  • Chemical contaminants from indoor sources: Most indoor air pollution comes from sources inside the building. For example, adhesives, carpeting, upholstery, manufactured wood products, copy machines, pesticides, and cleaning agents may emit volatile organic compounds (VOCs), including formaldehyde. Environmental tobacco smoke contributes high levels of VOCs, other toxic compounds, and respirable particulate matter. Research shows that some VOCs can cause chronic and acute health effects at high concentrations, and some are known carcinogens. Low to moderate levels of multiple VOCs may also produce acute reactions. Combustion products such as carbon monoxide, nitrogen dioxide as well as respirable particles, can come from unvented kerosene and gas space heaters, wood stoves, fireplaces and gas stoves.

  • Chemical contaminants from outdoor sources: The outdoor air that enters a building can be a source of indoor air pollution. For example, pollutants from motor vehicle exhausts; plumbing vents, and building exhausts (e.g., bathrooms and kitchens) can enter the building through poorly located air intake vents, windows, and other openings. In addition, combustion products can enter a building from a nearby garage.

• TRAP: Trap is the process of gasses and particulate matter attaching to the surface of the carbon and or zeolite structures.

• ZEOLITE: Zeolite is a mineral with a unique interconnecting lattice structure. This lattice structure is arranged to form a honeycomb framework of consistent diameter interconnecting channels and pores. Negatively charged alumina and neutrally charged silica tetrahedral building blocks are stacked to produce the open three-dimensional honeycomb framework. Zeolites actually attract odours & gases and trap them in tis crystalline structure.
