Air Conditioner Filter Types

Features of the different air-conditioning filter types
Reference for deodorising and antibacterial filter technologies used in applicable air-conditioning products
Different air-conditioning models may use different optional or integrated filter technologies. These filters are designed to provide functions such as deodorisation, antibacterial treatment and capture of fine contaminants.

1. Long Life Light-Deodorisation Filter

The long life light-deodorisation filter uses a combination of adsorption, oxidation and decomposition to reduce odours.

The filter material absorbs odour-causing substances and uses a catalytic process to assist with deodorisation. Exposure to ultraviolet light is also used as part of the regeneration process.

Deodorising Performance Shown in the Original Reference
Odour SubstanceReduction Shown
AmmoniaApproximately 60%
AcetaldehydeApproximately 35%
Acetic AcidApproximately 75%

Filter Regeneration

The original reference states that the filter may be reused for approximately 3 years by periodically regenerating it.

Regeneration method: Dry the filter in direct sunlight for approximately 6 hours, with around 6 months used as the standard interval.

2. WASABI Anti-Bacterial Electrostatic Filter

The WASABI filter combines electrostatic capture with an antibacterial ingredient derived from wasabi.

Static electricity is used to attract invisible mould, bacteria and other microorganisms. The filter then uses a volatile ingredient called allyl isothiocyanate, identified in the reference as the pungent component of wasabi, to help suppress reproduction and deactivate microorganisms.

CaptureStatic electricity attracts microorganisms to the filter.
Active IngredientAllyl isothiocyanate derived from wasabi.
PurposeHelps suppress reproduction and deactivate captured microorganisms.

What is Wasabi?

Wasabi, also known as Japanese horseradish, is described in the original material as having antibacterial and insect-repelling properties and having traditionally been used with foods such as raw fish.

3. Long Life Ion Deodorisation Filter

The long life ion deodorisation filter is designed to reduce odours using an oxidation-reduction process.

The filter uses ions generated within ultra-fine ceramic particles to break down odour-causing substances that have adhered to the filter.

Operating principle: Odour molecules are broken down through oxidation and reduction reactions generated within the ion deodorisation filter material.

Cleaning and Reuse

When the surface of the filter becomes dirty, the original reference states that it can be washed with water to restore its deodorising effect.

The filter is described as reusable for approximately 3 years.

4. Apple-Catechin Anti-Bacterial Filter

The Apple-Catechin filter combines electrostatic capture with polyphenol compounds derived from apples.

Small dust particles, invisible mould spores and microorganisms are attracted to the filter by static electricity. The polyphenol material is then used to help suppress microorganism growth and deactivate captured contaminants.

Apple Polyphenol Components Shown
  • Chlorogenic acid
  • Condensed tannin
  • (+)-Catechin
  • (-)-Epicatechin

What is Apple Polyphenol?

The source describes polyphenol as a natural plant component found in vegetables, fruit and tea.

Apples contain a relatively high concentration of polyphenols, particularly in young or green apples. The reference identifies catechin and tannin among the polyphenol compounds present.
