Best media, superior design
The GC MultiGas combines the best media in the industry with superior IQAir design to provide an unequaled level of protection against gases, odors and chemicals. The four disposable gas-phase filter cartridges of the GC MultiGas feature 12 lbs. (5.4 kg.) of the highest-grade activated carbon from bituminous coal, not the cheap coconut-shell carbon others use. Alumina pellets impregnated with potassium permanganate remove formaldehyde from the air. And the cylindrical shape of the GC MultiGas cartridges allows for optimal contact between the air and the filtration media, while offering very low air restriction. Meanwhile, HEPA post filters wrap each cylinder, preventing any media dust from being released while further improving overall system efficiency.
The GC MultiGas features two particle filters that work in tandem to provide an overall reduction of more than 99% of all particles (0.3 microns and larger) in the air. First, a HEPA Pre-Filter eliminates micro- and nano-particles such as allergens, smoke, bacteria and viruses. This stage of filtration also helps extend the life of the gas-phase media by preventing the gas-control cartridges from clogging with particulates. Additionally, each GC MultiGas gas-phase cartridge is wrapped with a micro-charged post-filter sleeve that eliminates particles released in the activated carbon adsorption and alumina pellet chemisorption media. The GC MultiGas features an H11-class HEPA Pre-Filter that delivers a total system efficiency of 99% or more for all particles 0.3 microns or larger. And the effectiveness of each and every GC MultiGas system is tested at the factory and certified to deliver what it claims. The GC MultiGas filter is also proven and certified to trap 95% of all particles down to 0.003 microns, the smallest particles that exist. This includes the entire range of ultrafine particles, the smallest and most harmful particles in the air.
