The first Medical Grade air purifier from ECOM® lays claim to be the leader in the product category. A 4-in-1 machine incorporating a large CIO2 filter, primary anti-bacterial filter, HEPA filter (world’s longest at 12m), and a negative ion plasma generator, it actively detects the pollution level in the room to adjust the filtration level. Strong enough to eliminate, deodorize and humidify (optional feature) a space of up to 1,000 square feet, yet quiet enough to ensure that you get a good night’s sleep.
