Why Air4? It works

100 times more efficient than air purifiers

Instead of trying to clean your entire room with an air purifier, the Air4 uses TLA (temperature-controlled laminar airflow) technology to provide perfectly clean air to your breathing zone while you sleep while also lowering the overall particle exposure in the room.

Only with the Air4, particles such as allergens, dust, bacteria, pollen, pet dander, viruses and other airborne particles are all eliminated, leaving nothing but clean air to breathe while you sleep.
