The Philips PureProtect 3200 Series AC3220/10 lets you clean the air in large rooms. This air purifier is suitable for rooms up to 105 square meters. The HEPA 13/14 filter removes 99.97 percent of the smallest particles from the air. This means you’ll have fewer problems with allergens, viruses, and bacteria. You can connect the air purifier to a smartphone app, so you can control it remotely. The app also shows you more information about the air quality right away. On the highest setting, the noise level is slightly noticeable. That means you can use the air purifier while you’re working or watching TV.
