My flight was on Saturday evening and I ordered on Thursday night. I requested seller to rush my shipment and it arrived on Saturday morning! Seller is super responsive and super quick! In fact, he processed my order immediately on Thursday night!The AirTamer brand is well known and has been around for a long time. That's the reason why I choose AirTamer for my personal air purifier. The moment I power my A302 on and put my nose near it, I can feel the fresh ion stream. The device is extremely light and the adjustable lanyard feels good around my neck. From my personal research, the AirTamer A302 really works and it does clean the air and protects the wearer, provided you are using the genuine stuff. So, always buy from the authorized distributor (this seller is the authorized distributor for SG). A seriously good product from a seriously good seller! Thank you PuriHealth for your part in making my holiday trip a safer one! Will definitely recommend family and friends to buy the AirTamer range from you :)
