The company’s history includes government use in sophisticated settings such as post-911, government wide-spread distribution protecting area residents as chemical weapons were destroyed, and to protect from the PG+E gas leak in California. We think this says it all!

The coronavirus, with its diameter of 0.125 microns, is contained and the amount of virus reduced from the air, thanks to the Hepa filter’s fine 0.1 micron-sized pores: This is outstanding, on an industry-wide scale! A comparative study on asthma patients living in an agricultural area, educated how to clean for reduced asthma triggers, compared to those cleaning while also using the Austin air purifier, yielded notable improvements in the filter-using group. These products are designed to accommodate many environmental triggers for chemical sensitivity. Recent studies show that low levels of mixed chemicals may exceed the impacts of a higher level of one chemical alone. Boasting high quality, these purifiers cost far less than many other products. Whether you are living in California’s smoke and fire-ravaged environment, in the city, or just want to purify the air in your home, these top-of-the-line products are the best among the best. This is a very high-quality air purifier, which we are truly happy to tout! Based on 1% of our units sold, we will gladly donate one Austin Air purifier to nonprofits serving California residents in need. We believe that Everybody in Fire-Ravaged California deserves to have a high-quality air filter, regardless of funds, and we genuinely want to help! Thank you for your patronage, which will help this important cause.
