IQAir’s HyperHEPA filtration in the GC MultiGas is proven and certified to filter at least 95% of all particles down to 0.003 microns – the smallest particles that exist. Independent testing by laboratories and government agencies verifies the effectiveness of IQAir technology against ultrafine particles. When it comes to protection against ultrafine particulates, IQAir is the proven choice.
Reviewers rate IQAir air purifiers as the best systems available for MCS sufferers. Most other air purifiers simply are not effective enough to make a real difference in the quality of the air an MCS sufferer breathes. Equally important, IQAir does not use any technologies that add additional MCS triggers into the air, such as ozone or chemicals. And IQAir products are constructed of computer-grade ABS plastics that do not “off-gas” into the air.
