Conventional HEPA filter
Xiaomi's High Efficiency Filter
Less clean air
More clean air
HEPA filter is made of dense fiberglass to trap particles, which means that less clean air gets through the filter.
Xiaomi's filter integrated melt-blown PP fibers with electrostatics technology equipped with bigger fibers space, which enables a large volume of clean air to get through the filter.
Large volume air is forced to get through a dense HEPA filter, requires higher fan speed, which will generate higher noise.
Less dense filter allows air to easily pass even at high speeds, which results in much less noise.
Higher energy consumption
Lower energy consumption
In order to get more clean air, HEPA filter requires the motor to run at a higher speed, which causes higher energy consumption.
Thanks to less dense fibers, Xiaomi's filter consumes less energy to achieve the same volume of clean air.
