TOGA Filter

Setting New Standards in High-Performance Purification Technology

Physical and Chemical Properties

Formaldehyde Fumes

  • Formaldehyde is a colorless gas with a pungent, stifling odor.
  • Formaldehyde is an organic chemical used in architecture and interior design to manufacture wooden furniture, flooring, etc.  It is also used in the preservative treatment of textiles and clothing and is involved in the production of various compounds in the chemical and pharmaceutical industries.
  • Formaldehyde volatizes in the air, and when it evaporates with fine particles, it causes acid rain and ozone production.
  • If absorbed into the soil, it can cause problems with ecological balance.
  • It acts as one of the Earth’s greenhouse gases and contributes to rising global temperatures. 
  • It is highly toxic to humans and causes irritation to the respiratory system, eyes and skin.
  • Direct contact may cause urticaria, dermatitis, and damage.
  • Ingestion or exposure to large amounts may cause unconsciousness, convulsion, and in severe cases, death.
  • Formaldehyde is a chemically highly reactive and flammable substance.  At high concentrations there is a risk of fire and explosion.
  • Formaldehyde vapor is heavier than air , so it collects in low or confined spaces, and the gas poses a more dangerous fire hazard than the vapor.

TOGA Filter and Formaldehyde (HCHO)

TOGA filters are manufactured to remove harmful substances by mixing different adsorbent media based on the substance being removed.

Filter Test

Target Gas: Formaldehyde (HCHO)

Total Flow: 10L/min

Target Gas Concentration: 200ppm

Temperature: 23°C

Humidity: 65%

Adsorbent Media Weight: 4.9g

*Efficacy testing for TOGA filters is conducted on a single-substance basis, with a performance benchmark of 80% removal efficiency.

Concentration (ppm)Usage Time (month)Note
109.2Based on use of 1 hour per day and 30 days per month
501.9Based on use of 1 hour per day and 30 days per month

Case Study

Changes in formaldehyde concentration before and after installation of TOGA filter and toxic gas purifier.

Conditions where adequate exhaust air velocity was not met.

Formaldehyde Not Measurable
MAK 182ppm
Acetone 5500ppm

Use of GT SCIEN Toxic Gas Purifier equipped with TOGA Filter.

Formaldehyde < 1ppm
MAK Not Detected
Acetone < 1ppm

Testing results confirmed that the special TOGA filter could effectively remove formaldehyde while simultaneously purifying toxic gases like MAK and acetone.

Filter Design that optimizes toxic gas purification ability.

TOGA Filters maximize purification efficiency for diverse contaminants by utilizing its entire area upon equipment mounting.
