indicators The dust and allergen indicators will illuminate whenever dust or other irritants are detected by the air quality sensors.
Visual monitoring of air quality.
Whenever odors, dust or irritants are detected, the display will show the contamination level.

Photocatalytic purification - harmful impurities contained in the air are decomposed into harmless components using a special substance - a catalyst - under the influence of soft ultraviolet radiation.
A high-performance HEPA filter provides the final cleaning step in a multi-stage filtration system. Retain dust, allergens, bacteria. Cleaning efficiency - 0.3 micron - 80% / 1-3 micron - 99.97%

Plasma (electrostatic) cleaning - neutralizes tobacco smoke, aerosols, fumes, oil mist, fine dust particles.
Active carbon (coal) filter - absorbs (absorbs) harmful gases, designed to remove unpleasant odors and gas impurities.

Active carbon filter A carbon or carbon filter is essential for the absorption of harmful substances and unpleasant odors,
thus achieving a high degree of air freshness.
