Overview of the 4-stage air purification filter system

Air purifiers are mainly composed of a pre-filter that filters out living dust in the air, a deodorizing filter that removes odors in the air, and a HEPA filter that removes fine dust.
The fine dust we are concerned about can be filtered out by using a HEPA filter, and the special fiber filter used in the semiconductor clean room is a HEPA filter. It has excellent adsorption power and functions to filter fine dust.
Air purifier filters are classified from E (10, 11, 12) to H (13, 14) and U (15, 16, 17), and H13 to H14 are called HEPA filters.
The higher the number on the back, the higher the probability of filtering out 0.3μm dust particles. It is recommended to replace the filter with a new one every 3 to 6 months.

Step-by-step characteristics of the 4-step air purification filter system

• 1stPre-filter

  Removal of large visible dust and contaminants
  Duvet dust, pet hair, dead skin cells, lint, etc.
• 2ndDeodorization filter

  Removal of causative substances of sick house syndrome and odor substances in daily life
  Removal of polluted odors coming from outside and odorous substances harmful to the human body

• 3thMedium filter

  Removal of coarse fine dust, yellow dust, house dust mites, etc.
• 4thHEPA filter

  A high-performance ultra-fine dust filter that can remove 99.97% of fine dust of 0.3 micrometers is applied (Merv17 grade)
  . Fine dust comes out to 0 after 1 hour after the air purifying circulator is operated (fine dust, carbon dioxide, radon, etc. are discharged to the outside)

What is a HEPA filter?

HEPA (High-Efficiency Particulate Air Filter) filter is an air filter that removes dust in the air, and it has the ability to collect more than 85 ~ 99.97% of 0.3μm particles depending on the grade. The filter paper of the filter is mainly made of glass fibers with a diameter of 1 to 10 μm or less.

This filter can filter out contaminants such as ultrafine dust, allergens, bacteria, viruses, pollen, dust, mold, pet keratin, and cigarette smoke.

Competitiveness of HEPA filter

01	High dust collection effect against fine dust by applying MERV17 grade HEPA filter– Removes 99.97% of ultrafine dust with a size of 0.3μm or larger
02	A high-performance filter capable of filtering out ultra-fine particles – Top-grade filter mainly used in negative pressure hospitals, clean rooms, and medical laboratories
03	A filter was developed to purify radioactive particles in the air – Removal of contaminants such as ultrafine dust, bacteria, viruses, pollen, house dust, mold, pet keratin, and cigarette smoke
04	Removal of fine dust and pollutants – Removes 99.97% of ultrafine dust with a size of 0.3μm or larger
05	Operational guidelines for screening clinics for COVID-19 equipped with HEPA filters– Announcement of guidelines for air conditioners used in COVID-19 screening clinics to be equipped with HEPA filters as operating guidelines of the Central Disaster and Safety Countermeasures Headquarters
06	Remove allergens– Filters out substances harmful to the human body that cause allergies and reduces the risk of allergic reactions
