Long Life Ion Deodorization Filter
How the filter reduces odours and how it can be maintained
Purpose: The Long Life Ion Deodorization Filter is designed to reduce unpleasant odours by breaking down odour-causing substances captured on the filter surface.
How it works
The filter uses ultra-fine ceramic particles to generate ions. These ions support an oxidation-reduction reaction that breaks down strongly adhered odour compounds on the filter surface.
| Feature | Function |
|---|---|
| Ion generation | Ultra-fine ceramic particles generate ions at the filter surface. |
| Oxidation-reduction | The generated ions assist in breaking down odour-causing substances attached to the filter. |
| Long-life design | When the filter surface becomes dirty, it can be washed with water to restore its deodorizing effect. |
Odours targeted
The product information specifically demonstrates deodorizing performance against:
- Ammonia
- Trimethylamine
- Hydrogen sulfide
The supplied performance graphs show that odour concentration reduces significantly faster with a new filter fitted than with no filter installed.
Cleaning and service life
Reusable for approximately 3 years: The source material states that when the filter becomes dirty, it can be water-washed and reused, with restored deodorizing effect, for approximately three years.
- Remove the deodorization filter in accordance with the indoor unit operating or installation instructions.
- Wash the filter with clean water when the surface has become dirty.
- Allow the filter to dry fully before refitting.
- Replace the filter if it is damaged, deteriorated, or no longer provides an acceptable deodorizing effect.
Important: This filter is intended to reduce odours. It does not replace normal air-filter cleaning, ventilation, or removal of the source of a persistent odour.
Key point
The Long Life Ion Deodorization Filter provides a reusable odour-reduction function by using ion-based oxidation-reduction at the filter surface. With appropriate water washing, the deodorizing function can be restored and the filter may be reused for about three years.
