Features

Odor Sensor Function

This air purifier does not have an odor sensor function. Users need to manually adjust the settings based on their perception of the air quality, which may require more active monitoring.

Dust Sensor Function

The Purivortex AC400 does not include a dust sensor function. The absence of this feature means the device cannot automatically adjust its performance based on the level of dust particles in the air.

PM2.5 Display Function

This model does not feature a PM2.5 display function. Users cannot visually monitor the real-time air quality, making it harder to assess the purifier's effectiveness without external tools.

Filter Replacement Indicator Function

The filter replacement indicator alerts users when it's time to replace the filter, ensuring the air purifier operates at optimal efficiency. This prevents reduced air purification performance due to a clogged filter, maintaining consistent air quality.

Child Lock Function

The Purivortex AC400 does not have a child lock function. This means that the settings can be easily changed, which may be a concern for households with young children.

Sleep Mode Function

The sleep mode reduces operating noise to 20dB and turns off the lights, making it ideal for use in bedrooms. This ensures a quiet and dark environment, promoting better sleep quality for those sensitive to noise or light.

3.0
With a CADR of 110 m³/h, this air purifier is best suited for smaller rooms up to 880 sq. ft. It may not be as effective in larger spaces, requiring longer operation times to achieve the same level of air purification.
HEPA Filter Quality and Type
4.0
The H13 True HEPA filter captures 99.97% of particles as small as 0.3 microns, including common allergens, dust, and pollutants. This ensures high-quality air purification, making it suitable for allergy sufferers.
