Description

The Blue Pure 511 is a compact, whisper‑quiet air purifier designed for small rooms and tight spaces. Powered by Blueair’s HEPASilent™ dual‑filtration technology, it removes 99.97% of airborne pollutants down to 0.1 microns while using as little energy as a single lightbulb. Perfect for bedrooms, dorms, offices, and cozy living areas.

Cleans Your Air From:

  • [Coarse Particles (PM10)]: Dust, pollen, smoke, mould spores, pet hair.
  • [Fine Particles (PM2.5]): Smoke, pet dander, bacteria, viruses, transport emissions.
  • [Ultrafine Particles (PM0.1)]: Smoke, bacteria, viruses, cooking aerosols.
  • [Microorganisms]: Bacteria, fungi, viruses.
  • [Odours]: Food, pets, household smells.

How It Works:

  • [HEPASilent™ Dual Filtration]: Combines electrostatic + mechanical HEPA filtration to remove 99.97% of airborne particles down to 0.1 microns.
  • [3 Fan Speeds]: Choose low, medium, or high depending on room needs.
  • [Integrated Air Sensors]: Automatically detect changes in air quality.
  • [Washable Pre‑Filters]: Available in multiple colours to match your space.
  • [Compact 350° Design]: Place anywhere — top‑air outlet and wraparound intake.
  • [Ultra‑Low Energy Use]: Consumes as little as 16 W — less than a lightbulb.
  • [Whisper‑Quiet Operation]: 24–49 dB depending on speed.

A Top Pick For:

  • [Bedrooms]: Whisper‑quiet + auto‑dimming display.
  • [Small Flats]: Cleans up to 38 m² quickly and efficiently.
  • [Dorm Rooms]: Compact footprint fits on shelves or nightstands.
  • [Home Offices]: Quiet enough for calls and focused work.
  • [Allergy Homes]: Removes pollen, dust, pet dander, mould, and bacteria.

Why We Like It:

  • [Compact & Stylish]: Scandinavian design that fits anywhere.
  • [HEPASilent™ Advantage]: Faster, quieter, and more energy‑efficient than traditional HEPA.
  • [Simple One‑Button Control]: No complicated menus — just tap to change speed.
  • [Washable Pre‑Filters]: Easy to clean and customise.
  • [Independently Proven Performance]: Strong CADR ratings for smoke, dust, and pollen.

Care and Maintenance:

  • [Filter Replacement]: Replace every 6 months; LED turns red when needed.
  • [Pre‑Filter Cleaning]: Wash or vacuum to maintain airflow.
  • [Placement]: Works best in rooms around 16 m² for AHAM‑recommended air changes.
  • [Noise Management]: Use low speed for night‑time whisper‑quiet operation.
  • [Energy Use]: Runs efficiently even 24/7.
