Air polluted with potentially harmful chemical and biological matter is purified and pollutants degraded to less hazardous substances by a combined chemical and electrochemical process. Scrubber liquid-electrolyte circulated between scrubber and electrolyze zones containing an electrochemically renewable degrading complexes or oxidizes the pollutants with the aid of an electrochemical cell in the electrolyze zone which also reactivates the degrading in the scrubber liquid for recycling. Adsorption of insoluble organics is enhanced by stable surfactant additives to the scrubber liquid-electrolyte. Surprisingly, the electrochemical cell performs efficiently without separators or membranes when the non-working cathodes comprise Magneli phase substoichiometric titanium oxides which preferentially generate hydrogen instead of reducing redox couples to their inactive lower valence state
Apparatus for treating indoor air
Apparatus for purifying indoor air comprises a blower for circulating air through a duct and removing particles and neutralizing a number of harmful gases through a process of molecular catalytic cracking of heavy hydrocarbons at ambient temperatures. Preferably, the apparatus includes a series of treatment elements including an ozone generator for producing a oxidator gas, a bio-mass collector, a filter coated with zeolite and surface modified hopcalite for removal of CO and NOx compounds, a filter coated with calcium carbonate for removing carbon dioxide and hydrophilic compounds, a filter coated with zeolite for solvents such as MEK and adsorbing water, and one or more filters for removing particulates in the air stream. The filters thus remove particulates and neutralize a number of harmful gases that may be present in indoor air.

1.DUST COLLECTORS
Scientific Dust Collectors manufactures a full line of Cartridge dust collectors to meet the needs of your specific operation. For over 28 years, SDC has provided customers with unmatched cleaning performance. This is primarily due to our superior cleaning system that employs a patented supersonic nozzle to clean the filters more effectively than any of our competitors.
Cartridge dust collectors are ideally suited to capture granular shaped dusts. These are free-flowing materials that collect on the outside of the cartridge filter pleats and are easily released from the media during the cleaning cycle. Cartridge collectors are ideally suited for smaller particle dust sizes (less than 50 microns) and low grain loading levels (less than 5 grains per cubic foot). Some examples of dusts that are collected during cartridge collectors are grinding or sandblast applications, welding fumes, laser and plasma cutter fumes, graphite, pharmaceutical powders, and fine chemical powders. These dusts require minimal flexing of the media during the cleaning process; thus, cartridge collectors will work satisfactory on these products. When the dusts are difficult to handle, hygroscopic, or high temperature, a fabric filter bughouse is a better alternative for trouble free dust collection and longer filter life.

3.HEPA Filters
filters are regarded as the best form of air filtration devices available today. HEPA stands for High-Efficiency Particulate Arrestance. According to U.S. Military Standard MIL-STD-282, HEPA filters are defined as air-cleaning devices that have a proven minimum removal efficiency of 99.97% of particles in the air equal to 0.3 um (microns) in diameter with higher efficiency for both larger and smaller particle sizes. The reason 0.3 microns is used in the definition is because it’s the particle size in which all mechanical filters are LEAST efficient in capturing and removing from the air. A micron is a measure of length: 1 micron equals 1 millionth of a meter. A particle size of 10 microns or less is not visible to the naked eye.
The Model 754 comes equipped with an internal compressor. The compressor is a mechanical component that generates air pressure for ventilation. Pressure is needed to deliver a volume of gas to the patient. In order for the compressor to operate, it needs to entrain air from the atmosphere. The Eagle’s™ air entrainment port does not come with a HEPA filter installed. When the ventilator is operated in a clean environment like a hospital, a HEPA filter covering the air-entrainment port is generally not needed. It is highly recommended that when the ventilator is operated in environments where it is exposed to higher than normal levels of airborne contaminants that a HEPA filter be installed. The HEPA filter will help protect the inside of the ventilator from contamination and prolong the life of the internal components by preventing the buildup of foreign matter like dust and dirt.
Use of a HEPA filter will also help protect the patient’s airway from exposure to this foreign particulate matter. Undesirable contaminants that the HEPA filter will help block include; smoke, mold, hair, dust, dirt, pet dander, bacteria, viruses and fungi. Please note that “HEPA-Type” filters may look like a certified HEPA filter however their performance may not match that of a true HEPA filter. No filter, including a true HEPA filter, can trap 100% of all contaminants. However, in terms of efficiency and performance, HEPA filters are the highest performing air filtration devices currently available. HEPA filters should ALWAYS be used in situations where the ventilator must be operated in contaminated environments. Two additional features of HEPA filters that add to their value is that unless the air entering the filter is humidified, bacteria and viruses that are trapped in the filter will dry out and die. The second feature is that the filter becomes more efficient over time because as the filter gets filled with trapped particles, it becomes more difficult for matter to pass through the filter. Depending on use and level of contaminate exposure, HEPA filters, like a regular filter need to be changed based on the manufacturer’s recommendation

5. Residential Air Cleaners
Although official efforts to control air pollution have traditionally focused on outdoor air, it is now apparent that elevated contaminant concentrations are common inside some private and public buildings. Concerns about potential public health problems due to indoor air pollution are based on evidence that urban residents typically spend more than 90 percent of their time indoors, concentrations of some contaminants are higher indoors than outdoors, and for some pollutants personal exposures are not characterized adequately by outdoor measurements. Among the more important indoor contaminants associated with health or irritation effects are passive tobacco smoke, radon decay products, carbon monoxide, nitrogen dioxide, formaldehyde, asbestos fibers, microorganisms, and aeroallergens. Efforts to assess health risks associated with indoor air pollution are limited by insufficient information about the number of people exposed, the pattern and severity of exposures, and the health consequences of exposures. An overall strategy should be developed to investigate indoor exposures, health effects, control options, and public policy alternatives.
6. Cigrate Smoke Remover
The first problem of cigarette smoke are the many toxic gasses produced by burning cigarette's.
These gasses are in part produced because cigarette manufacturers dose the tobacco in many different chemicals in order to flavor the cigarette's and keep them burning. Ammonia gasses, Carbon Monoxide, and phenol are just a few of the dozens of toxic gasses produced when cigarette's are burned. Besides being highly toxic, these gasses also emit many foul odors
The second problematic component of cigarette smoke is the very high level of tar solids that are disseminated into the air when cigarette's are burned. This is the same petroleum based tar used to make asphalt roads. This petroleum based tar clouds the air and sticks to every surface of the room. Not only can you see this tar in the air you can also see and feel this yellow brownish sticky substance on surfaces such as walls and furniture. Cigarette smoke tar even seeps into your homes air vents, and appliances with vents such as TV's and stereos. This disgusting goop discolors paint and it also has a terrible, sickening odor.
Cigarette smoke produces airborne tar just like this.
