Even though there are many products on the market that claim to disinfect or purify air/water/objects, they typically ask us to trust they’re working on blind faith with no way to actually show that there’s a tangible toxin in need of removing. With typical air purifiers, there will eventually be the bits of dust or hair stuck in the filter after a few weeks, but nothing visible day to day to let you know just how dirty the air is. Sharper Image now has available an air purifier with a pollution sensor lamp that glows red when the surrounding air is highly polluted, dark purple for moderate pollution, light purple for low pollution, and blue for clean air. A 3-stage Hepa filter cleans 99.5% of airborne particles and will cover a room up to 24o square feet. It’s available through Sharper Image for $279.99.
