Designed for a life with less cleaning, the DustMagnet 5210i air purifier catches 99% of airborne dust before it settles on floors and surfaces. Independently tested for performance as part of the AHAM Verifide Program for room air cleaners, for a Clean Air Delivery Rate (CADR) of 154 cfm for smoke, 173 cfm for pollen, and 153 cfm for dust. Recommended for small to medium rooms like a guest bedroom, home office, or dining room, the 5210i completely filters room air about every 12 minutes (approx. 5x an hour at 238 ft) on the highest speed. Patent-pending DustMagnet technology powerfully attracts airborne dust particles like a magnet. Two air intake points and a unique airflow pattern create a vortex effect in the room to capture dust before it settles. A stream of negatively charged particles clusters airborne dust particles, making them easier to capture. Once inside, the particles stick to the positively charged pre-filters like a magnet. Equipped with HEPASilent™ filtration technology to kill germs and effectively trap 99.97% of airborne particles like allergens, dust, pollen, pet dander, viruses, and more down to 0.1 microns. Plus, activated carbon is integrated throughout the filters to absorb light household odors from cooking, smoke, and pets. Air purifier not tested against SARS-CoV-2 (COVID-19). DustMagnet delivers more clean air using less energy and less noise. The 5210i quietly cleans the air with noise levels less than a whisper (29 dB) on low and less noise than a normal conversation (45 dB) on high – while using less energy than a light bulb (5-22 watts) on all speeds. Designed to blend into your home like a great looking piece of Scandinavian-style furniture, the dual-use design features a convenient top surface to double as a side table and air purifier. With a design worth showing off, there’s no need to hide your air purifier, place it prominently in the room where it will be most effective. DustMagnet is equipped with proactive features such as Auto mode, Welcome home, and a five-color air quality indicator light. Set to Auto mode and the air purifier will auto-increase fan speed when pollution levels creep up (when cooking, vacuuming, etc.) and returns to a lower speed when cleared. The Wi-Fi-enabled model can be controlled from almost anywhere with the Blueair app and voice-control via Amazon Alexa and Google Assistant-enabled devices. Includes one set of ComboFilters with a maximum of 1-year filter life and two permanent stainless-steel pre-filters. DustMagnet proactively monitors filter use and pollution levels in real-time to accurately determine when you need a filter change.
