| When we tested the IQair air purifier, virtually nothing escaped its Hyper-HEPA filter. Packed with superior technological features such as a huge capacity pre-filter, filter change indicator lights, a HEPA filter efficiency rating second to none we have tested, and six fan-speed settings, the IQair is as good as it gets. The Hyper-HEPA filters out smaller particulates than other filters, and these tiny particles are the ones which are actually injurious to your health. We are particularly impressed with its robust pre-filter which screens out 90% of all larger allergens. We can find no equal in any other purifier. The quality of its carbon fill is the best you can find, so simply put, it does a better job. Warning lights tell you when to change any of the filters. No expense has been spared in the manufacturing of this machine. The IQAir air purifiers series filters out pet dander, viruses, pollen, dust mites, mold spores, odors, and bacteria. This air purifier is for those who know their health deserves only the very best and who want to ensure clean air in their homes.  |
