Review on NextScent Ventus Go 4 in 1 Portable Air Care System (Black) - Pure Air & Scent Diffuser with Digital Air Quality Sensor, 4-Stage Air Purifier, Odor Eliminator – Quiet, Compact for Home, Work, Cars, Trucks, RVs, & Travel – 8hr Rechargeable Battery by Pamela Jones

What a perfect gift item! I bought this filter for my father who smokes for use in his home office. I liked that he could open the box and get started right away. The controls are very easy to use and the display is nice and clear. When it's running it's very quiet, so you can have it right on your desk without noticing it (except for noticeably fresh air coming out of it!); and with its slim and compact design, it fits almost anywhere. NextScent customer support is fantastic - super responsive and extremely helpful.
