Perfect for auxiliary power sir purification

I live in an area which there is an increasing frequent number of power outages, combined with high average PM2.5 pollution. To combat this problem, I purchased a battery based auxiliary power system. For the air pollution problem component, I needed the most energy efficient air purifier for a room of about 300 ft2. Of all purifiers available in the market, this unit is the most energy efficient for a room up to 388 ft2 at 8.4 Smoke CADR/W.
I would recommend this to a friend!
