Air Oasis makes air purifiers that are carefully assembled by hand in their Amarillo, Texas factory. Their breakthrough AHPCO® technology was originally developed by NASA, does not rely on filters, and is virtually maintenance-free. Unlike other air purifiers, Air Oasis actively purify the air AND surfaces throughout a room. If a virus makes it on a surface (like a door handle) and then you plug in your Air Oasis, the technology is able to kill the virus on that surface. Air Oasis clients include the tallest building in the world, hospitals, professional sports teams, 5 star resorts, casinos, dog kennels, industrial facilities, and tens of thousands of homes.
