Odor From Tobacco / Cigarette / Cigar Smoke

• Electrocorp 9400 CM series, ceiling and wall mount air filtration system
  Smoke and invisible vapor from cigarettes, cigars, and pipes are some of the main causes of odors in smoking areas in restaurants, bars and other public and private smoking areas. The odor is persistent and difficult to eliminate, even with a large amount of ventilation. However, it can be effectively reduced, if not removed completely, with a properly designed air purification equipment using the appropriate impregnated carbon media.
• Smoke (fumes) from tobacco smoke creates an irritating smog-like blue haze, which will disappear, but odors and chemicals associated with smoking will linger for days. Impregnated activated carbon media used in the Electrocorp 9400 CM series air cleaner, air purifier, air scrubber can help reduce both the irritating vaporous portion of smoking and any stale odor that remain long afterwards.

On Second Hand Smoke

• Second hand smoke has been classified by the U.S. EPA as a Class A carcinogen | More  |
• Disclaimer: Espitech Air Products disclaims all warranties, implied or otherwise, that anyone (non-smoker or smoker) who installs our air purifiers, air cleaners, or air scrubbers as an alternative to seeking a smoke free environment will be protected from the health risks caused by exposure to second hand smoke.
• "No air filtration or air purification system has been designed that can eliminate all the harmful constituents of secondhand smoke. A reduction of the harmful constituents of secondhand smoke does not protect against the disease and death caused by exposure to secondhand smoke. The U.S. Surgeon General has determined secondhand smoke to cause heart disease, lung cancer, and respiratory illness."

Nature Of Tobacco Smoke

• Tobacco smoke consists of nicotine, tars, water vapor, carbon dioxide, and a substantial number of chemicals and many other irritants. Tars adhere to walls, furniture, carpets, clothing and other articles having large surfaces. After most of the vapor and smoke in the air has been removed by the impregnated carbon media, the walls and other surfaces may retain a film of liquid tar, much of which slowly evaporates back into the air.
• Carbon media is the most adsorbent material known to man, and is the adsorbent of choice by the military, industry, healthcare institutions, and of environmental organizations. | Google- more on activated carbon , activated charcoal |
• Allerair D/S and DX/S series with the double activated carbon media together with a matching smoke specific pre-filter (Tar pre-filter), does not hide or mask the odors, chemicals and gases as some other systems do. Allerair and Electrocorp units do not use Ozone, which itself has been labeled a pollutant. According to the American Lung Association and Health Canada, it is dangerous to one's health when you breathe in additional ozone.

How Smoke Odor is Removed

• When first turned on in an already smoke-filled room, the first effect is the removal of the sharp irritants that affect the eyes and the nose. If an  impregnated media filtering unit is already running when smoke starts, the smoke and the vapor is eliminated and an odor free condition can be obtained after smoking stops. This always depends on a variety of factors: sufficient carbon modules, strategic placement, appropriate matching filters, adequate maintenance and operating modules 24 hours a day.
• The elimination of the less acrid tar and chemical odor, and the reduction of the visible mist of liquid tar require little time in most settings. The removal of the remaining odor, which comes from tar and chemical re-emissions from walls, carpets, draperies and furniture, may take several hours to many days, depending on smoking volumes.

Cost Savings

• When an Allerair or Electrocorp air purifier air cleaner air scrubber air filtration system is used (specifically designed for tobacco smoke with appropriate impregnated carbon and matching pre-filters are available), indoor air can be re-circulated. Therefore, it is possible to save the costs of energy and maintenance of the heating & cooling systems used to pump in outdoor air. Allerair air purifiers air cleaners air scrubbers air filtration systems can help save you money on cleaning bills. These savings alone can more than pay for the air purification system. The activated carbon media can be replaced easily and at a minimal cost.
