The IQAir is the air purifier we use in the CR Way Longevity Center. It's a workhorse that cleans a very large space very effectively. We combine the HealthPro Plus with a Winix 5300 to clean an open, multilevel space with five rooms. If you also experience noxious gases, consider the IQAir New Edition MultiGas Air Purifier, which we use in the Longevity Center gym. Regrettably, it is not available through the Amazon affiliate program, so we are unable to offer it at this time.
Here is how IQAir describes it's product -
Proven and certified as the world's best performing air purifier. Filtering ultrafine particles down to .003 microns (inc. viruses, air pollution, allergens, smoke and industrial fumes). Patented HyperHEPA® filtration is up to 100X more effective than standard HEPA. Entirely designed and manufactured in the IQAir factory in Switzerland.
