Clean Air Filter Premium—Providing you with the finest in luxury spaces—

Cabin air filters (for use in car air conditioners) are fitted inside the air conditioner and remove dust, pollen and other particles before they enter the car interior. Additionally, they also absorb odors from exhaust fumes and other sources to ensure clean air inside the car interior.
Toyota Boshoku engages in consistent production from development of core filter materials to development of production technology and facilities, and finally to assembly.
In order to meet society’s needs we have assembled a wide lineup with various different functions.
Below we will introduce the functions of Clean Air Filter Premium—Toyota Boshoku's highest grade of air filters.

High-Efficiency Dust Removal

Blocks PM 2.5 pollen and particles

The 3-layer structure of this filter intercepts particles such as dust and pollen from outside the car thanks to highly efficient dust removal capabilities.

High-Efficiency Dust Removal
  • Note: The removal percentage listed in this graph is based on the results of internal company testing where test powder was passed through a filter a single time and the percentage of powder removed was observed.

Deodorization

Removal of odors from exhaust fumes and pets

Makes for a more comfortable car interior through the use of newly-developed activated carbon for powerful absorption of unpleasant odors, such as exhaust fumes odor (acetaldehyde) from nearby traffic, as well as pet odors (ammonia).

Deodorization
  • Notes:
    1. Image is for illustrative purposes
    2. Ability to deodorize various odors is based on Toyota Boshoku internal test results

Antiviral Performance

Reduces virus on surface by 99.9%

Treatment of the filter’s surface with antiviral agents reduces the number of viruses sticking to the filter.

  • Note: It does not guarantee results for all viruses or environmental conditions.

Antiviral performance

Antiviral performance
(Testing agency)
Japan Food Research Laboratories (JFRL)
(Testing method)
TCID50 assay
(Testing conditions)
Sample size 3x3cm
Virus type: ATCC VR-1469
A viral suspension is applied onto a sample piece of filter, with viral infectivity measured after 24 hours of storage at room temperature

Allergen Suppression

Filters ticks and pollen by at least 90%

Anti-allergen material ensures a 90% or greater reduction in allergens such as pollen and dead ticks sticking to the filter over a 24 hour period.

  • Note: It does not guarantee results for all allergens, viruses, molds, bacteria or environmental conditions.

Anti-Allergen Performance

Allergen Suppression
(Testing method)
Sandwich ELISA test
(Testing conditions)
Sample size 8x8mm
Allergen concentration:
Cedar pollen 1ng/ml
Ticks 100ng/ml
Allergen solution volume: 0.3ml
Allergen contact period: 24 hours

Anti-bacteria & Anti-Mold Performance

Guards against bacteria and mold

Treatment of the filter’s surface with an anti-mold agent prevents reproduction of mold sticking to the filter, and reduces unpleasant odors from emanating from the air conditioner.

Vitamin C Release

Vitamin C to moisturize the skin

Application of vitamin C ceramic to the filter allows vitamin C to be released alongside refreshing air to help moisturize the skin.

  • Note: Results may vary between individuals
