At the bottom, it has a regular USB jack to charge the device, while the on/off switch sits at the bottom-left side. There are tiny bristles at the top to emit negative ions and an LED indicator at the back indicating if the device is on or off. Also, the device has a strap, so you can even wear it around your neck.
The Air Tamer A-310’s little bristles emitting negative ions attract injurious particles, including atomic-sized pollutants — viruses, pollen, smoke, moulds and dust mites — present in the air. These negatively charged particles naturally get attracted to the positively charged surface, rather than sailing towards people breathing that air. This significantly reduces the inhalation of such particles by users.
We used the Air Tamer A-310 outdoors — in busy streets, and even while riding a bike. The air purifier
has a battery life of 150 hours; it easily lasted over a week. The device works on the electrostatic purification technology, so it does not have any filter unit. The company claims that it creates a 3-foot radius of cleaner air around itself. However, in the absence of an indicator, it is not possible to verify this. But we did bring the device closer to the nose to see if one felt any difference; we felt a there was some change in air quality.
Priced at Rs 9,999, the Air Tamer A-310 is certainly not cheap. The idea of a portable air purifier
is impressive, given the health risks posed by air pollution. But the technology
might still take some time to evolve before it can become a worthy substitute for traditional air purifiers in cities like Delhi.
