Hand Dryers on Parade

Are you tired of drying your hands on the front of your jeans?

James Dyson, who invented the company’s bagless vacuum cleaner, is also working on a solar-powered car. Dyson doesn’t mention this much, but hand dryers like this have been staples in Japanese public bathrooms for several years. You see them in convention centers a lot.

The vacuum-cleaning innovator Dyson had its Airblade hand dryer at the show. The Airblade contains a filter that can remove 99.9 percent of the bacteria from the air, said a company spokeswoman. The dryer also uses up about 80 percent less energy than your standard warm air hand dryer, and it’s less expensive than paper towels, which Dyson says can save on costs by 98 percent.

It only looks like it’s going to bite your hands off. After getting a quick spritz of water, I plugged my hands into the machine. They were dry in only a few seconds.

Air pollution doesn’t stop at the front door to your house. Some pollutants are stronger indoors than outside.

The execs at the show didn’t have much to say about how energy efficient the air filter was. They did note, however, that the energy-efficient home of today might conserve energy, but that also means it is better at holding in nasty air particles.

That’s the idea behind Trane’s CleanEffects filter. The unit filters out allergens and other particles (smoke, bacteria, mold, pollen, spores, etc.) from the air. The CleanEffects filter connects directly to your heating or air conditioning system to reduce indoor air pollution. The filters can be vacuumed or washed if they start to look like the lint trap in your dryer.
