LEVEL OF THE ULTRA-FINE PARTICLES
What’s the Fine dust
The size of the fine dust is lower than 10
µm
.
What’s Ultra-fine particles
The size of the ultra-fine particles is lower than 2.5
µm
. And a study founded that smaller particles
are more harmful to the body.

• Dust level is shown in number from 5 to 500.
• Dust level is established with reference to the data provided by a manufacturer of sensor.
• Ultra-fine particle level (colored) is made with reference to the ultra-fine particle level provided
by the Ministry of Environment.
• Ultra-fine particle level shown on the product may differ from the announcements of the Minis-
try of Environment.
• The Ministry of Environment estimates the ultra-fine particle level using gravimetric method and
beta-ray method. But HORIZON HA-500 air-purifier estimates.
the amount of dust and changes it into concentration. Therefore, the results could be different.
