Even in oil mist and water vapor situations
Continuous performance is maintained / DPF technology is applied
Dust collection rate changes over time when used without cleansing
Existing equipment’s (ESP*) efficiency is 20% or less after 5 hours.
* ESP : Electrostatic Precipitator
* Drops to 20% w/o cleaning,

Not only removes PM but also sterilizes germs, viruses and removes odors at the same time.
The ceramic filter of DPF with a porosity of 50% or higher adsorbs PM and odors at the same time.
Unlike activated carbon, which requires replacement, the filter is refreshed by the decomposing process of the catalytic reaction during the self-cleaning process.
Activated charcoal/activated carbon with deodorization effect using adsorption of pores - Replacement needed
[Microstructure of activated charcoal]
Powerful dehumidification and deodorization power
from mysterious pores!
Can you see the mysterious pores of activated bamboo charcoal?
The surface area of 1g of Hole & Hole Activated Bamboo Charcoal is about 1,200m². This is a result of the activated bamboo charcoal’s spread numerous pores, whose large surface area is what drives the adsorption of different scents and moisture. This is the reason why Hole & Hole Activated Bamboo Charcoal powerfully adsorbs a variety of odors and moisture in daily life.
High porosity of the ceramic filter of Khanfilter, continuously usable without needing replacement due to its self-cleaning
