Sometimes, the shrewdest things can also be the most simple. Take HEPASilent Technology, Blueair’s patented filtration system, which radically improves the quality of indoor air.
“First, the air is sucked in and the contaminant particles receive an electric charge,” says Johan Wennerström, technical and innovation director at Blueair. “In step two, the particles are separated in a filter. Larger particles like dust adhere directly, but small particles are also caught, because the electrical charge means they get drawn in and trapped in the filter.”
For those who aren’t technically minded, Wennerström offers a handy analogy: “It’s like when you rub a balloon against your hair and charge it with static electricity. It will then stick to a wall.” In the filter, this static charge is about something more than party games, however. “Out comes much cleaner air: the level of efficiency is 99.97 per cent. If you have asthma or suffer from allergies, you may notice a big improvement. And in China’s polluted cities, for example, a room air purifier is a must.”
But breathing easy isn’t the only benefit of an air purifier with HEPASilent Technology. As the name suggests. “It requires less fan power and is therefore quieter. And that’s definitely good when you’re sleeping.”
