NOTE: *Blueair Blue 3610 & Blue Pure 211+ Auto are the same product, which previously was known as Blueair Blue 3610 With Particle + Carbon Filter (Plus Arctic Trail Pre-Filter Cloth) Product Highlights: ① Designed for large rooms ② Powerful HEPASilent™ Filtration Technology ③ Three-part filtration ④ Customizable pre-filters ⑤ Sleep without disruption ⑥ Simple to place ⑦ Low energy consumption ⑧ LED air quality display ⑨ One-button design ⑩ Easy filter change Product Features: ① Designed for large rooms Filters the air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 51 m² room to effectively lower particle levels and maintain a comfortable environment in large living rooms, family rooms & playrooms. ② Powerful HEPASilent™ Filtration Technology Our unique combination of electrostatic and mechanical filtration that we call HEPASilent™ filtration technology sets us apart. The combination allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance— resulting in quieter and more energy efficient air purifiers. ③ Three-part filtration A fabric pre-filter offers the first layer of protection, catching large particles and extending the life of the primary filter. The combination Particle + Carbon Filter uses a layer of activated carbon to filter light household odors from pets, cooking, and smoking, while the main particle filter removes airborne particles, like pollen, dust, pet dander, and more. ④ Customizable pre-filters Adapts to your space with multiple color options. The colorful fabric doubles as a pre-filter, catching large particles and extending the life of the primary filter. Simply vacuum the fabric or toss it in the washing machine whenever it needs cleaning. Go without the pre-filter altogether for a clean Scandinavian look ⑤ Sleep without disruption Noise-levels are no louder than a whisper on the lowest speed (31 dB) and equivalent to the noise level of rainfall on the highest setting (56 dB). ⑥ Simple to place Unlike some air purifiers with strict rules for placement, the Blue 3610 uses a 360-degree air intake, meaning you can place it almost anywhere in the room without compromising performance. ⑦ Low energy consumption Energy efficiency (30-61 W) - certified room air purifiers are 40% more energy-efficient than standard models, so you can run your air purifier 24 hours a day without concern. ⑧ LED air quality display Stay up to date on the status of your indoor air with the LED air quality indicator (AQI). The display changes color to indicate good, moderate, or poor based on the current concentration of fine particles (PM2.5) measured by the integrated particle sensor. ⑨ One-button design Forget about adjusting settings and knobs - a single button controls it all and lets you know when it's time to replace the filter. After about 7 seconds, the button's LED light automatically dims to 0% brightness. ⑩ Easy filter change The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing the filter about every 6 months when used 24 hours a day.
