The Wide Spectrum Chemical and Odor Control Specialist - The GC MultiGas has been customized for wide spectrum molecular and particulate contaminant control. Just like a professional gas mask, the GC MultiGas maximizes molecular filtration for a wide variety of gaseous chemicals and odors with its advanced filter cartridge design. And while gas and odor control is a particular strength of this system, the GC MultiGas also offers excellent filtration for particles. The GC MultiGas indoor air purifiers are ideal for controlling cigarette smoke and odor as well as addressing the needs of those that suffer from MCS (Multiple Chemical Sensitivity). These air purifiers lack a true HEPA filter so although it is not ideal for asthma and allergy sufferers, it still filters 97% of particles at 0.3 microns. The filter system in these air purifiers consists of the standard pre filter but the upper module contains four filter cartridges that contain gas phase media. The filter cartridges are reusable and contain 12 pounds of the media. This GC MultiGas indoor air purifiers are designed to control the following: Vinyl chloride, Trimethylamine, Trihylamine, Trichloroethylene, Sulfur trioxide, Styrene, Skatole, Phenol, Ozone, Nitroglycerine, Methylamine, Methyl vinyl ketone, Methyl sulfid, Methyl mercaptan, Methyl ethyl ketone, Methyl disulfide, Methyl acrylate, Methanol, Isopropanol, Isoprene, Hydrogen chloride, Formic acid, Ethylamine, Ethyl acrylate, Ethyl acetate, Ethanol, Dimethylamine, Diethylamine, Cyclohexanone, Cresol, Chlorine dioxide, Carbon disulfide, Butyric acid, 1.3 Butadiene, Acrylonitrile, Acrolein, Acetone, and Acetic acid. These air purifiers are mainly used for customers with chemical sensitivity and to control tobacco smoke in the air. This product can control multiple chemicals such as acetic acid, isoprene, ethanol, hydrogen chloride, ozone, phenol and many more. This unit is the same dimensions and weight as the GC VOC and also comes with the remote control and six-speed fan. This product can also clean the air in a space up to 900 square feet. The GC MultiGas is able to trap chemicals and odors in the air with the powerful filters and cartridges it is equipped with. When IQAir developed these indoor air purifiers, they had power and accuracy in mind. The products in the series are effective enough to trap odors, chemicals and gases in the air. They have a 99% efficiency rate and require little energy to run. The IQAir series also offers such benefits, as the six-speed fan and remote control so that the air purifiers stay user-friendly yet remain powerful.
