Removes over 99% of dust & pollen

Unlike a standard fan, the Blue Pure Fan cleans as it cools, removing over 99% of airborne dust and pollen particles in just 20 minutes.


Based on third-party testing of removal rate of dust particles (2.839μm) and pollen particles (7.234µm) in 20 minutes at a room volume of 1,008 ft³ according to AHAM AC-1-2019 standard.​

Cools with patented fan technology

Patented air circulation technology delivers a gentle stream of clean air across a 90-degree range to effectively cool the entire room, without the need for oscillation.

Customizable pre-filter colors

The only purifying fan with customizable pre-filter colors to adapt to your space. The washable fabric pre-filter is available in five colors and designed to be used over and over. Vacuum the pre-filter or toss it in the washing machine when it needs a refresh.

Designed for sleep

Designed to help create an optimal sleep environment with gentle airflow to help lower body temperature, circulation of clean air, free of allergens that can irritate and disrupt sleep, and white noise on speed three to mask sleep-disrupting sounds.

Move freely

Versatile by design, the Blue Pure Fan can be moved freely from tabletop to floor with a convenient handle. The balanced design is light enough to move around your home, yet the low center of gravity makes it difficult to knock over.

Dust-free fan blades

Unlike standard fans with blades that get covered with dust and require disassembly to clean, the Blue Pure Fan captures airborne dust and pollutants before it has a chance to stick to the fan blades.

Extended filter life

The colorful fabric pre-filters catch large particles and extends the life of the main filter

Quiet, calming noise

Noise levels are equivalent to a whisper on the lowest speed (31 dB) and provide calming white noise on the highest setting (56 dB).
