According to the company, Renew will help the customer breathe and sleep better by improving the air quality in the room. The air purifier has a four-layer HEPA-13 filter that will remove 99.97 percent of particles, and a carbon filter that stops gas and odors. Airthings says Renew can clean the air in a typical bedroom in ten minutes, and is effective in rooms up to 50 square meters. In silent mode, it emits only 23 decibels, and by lowering the device with Airthing’s app, the user can monitor air quality from anywhere.
