BLUEAIR Blue Pure 511i Max Smart Air Purifier with Wi-Fi and HEPASilent

Some rooms call for broad air cleaning, while bedrooms and home offices benefit from a purifier designed to fit more naturally into a compact space. The BLUEAIR Blue Pure 511i Max combines HEPASilent filtration with Wi-Fi and automatic fan control. Its compact format suits everyday use in bedrooms, dorm rooms and apartments.

Quick overview

This purifier captures 99.97% of airborne particles down to 0.1 microns, including dust, pollen, pet dander, mould particles and smoke. Its HEPASilent filtration combines mechanical and electrostatic filtration, while the 360° air intake draws air in from around the unit. For a sense of its cleaning coverage, it can clean 237 sq ft in about 12.5 minutes, or up to 1,138 sq ft in one hour.

Built-in air-quality sensors adjust the fan speed automatically when pollution levels rise. Wi-Fi connects the purifier to the Blueair app, where you can monitor air quality, change settings, schedule operation and receive filter replacement reminders. A washable fabric pre-filter adds a practical option for catching pet hair, and the compact design is easy to place in a smaller room. The corded power supply makes it a plug-in choice for a regular spot at home.

Everyday use

Use the 511i Max in a bedroom, nursery, dorm room or home office where dust, seasonal pollen, pet dander or smoke particles are a concern. In a bedroom, its low-noise design is suited to running while you rest, in a home office, automatic fan adjustment can respond as indoor air conditions change. It can also help with everyday odours, including cooking and lingering smoke smells.

The washable pre-filter is useful for routine care, especially in homes with pets. Owners often highlight quiet operation, reduced dust and lingering smells, and a helpful app. Feedback on automatic mode is more mixed, so the app also gives you a way to check air quality and select settings yourself.

Who it’s for
