WDH-660b / WDH-988b Combi-Filter – Activated Carbon & Catalyst

Replacement filter for odor and pollutant reduction for Aktobis air purifiers

The combi-filter for WDH-660b and WDH-988b combines activated carbon and catalyst technology for the targeted reduction of unpleasant odors, smoke, and certain gaseous impurities. The custom-fit replacement filter is specially designed for the Aktobis WDH-660b and WDH-988b air purifiers and is easy to replace.

Odors and gaseous pollutants can arise, for example, from tobacco smoke, cooking, food, or various household substances. The activated carbon-catalyst filter complements the device's air purification and helps to reduce such pollutants in the indoor air.

Activated carbon meets catalyst:
The combi-filter combines two filter technologies in one component and is particularly suitable for reducing odors, smoke, and certain gaseous impurities in indoor spaces.

The main benefits of the WDH-660b / WDH-988b combi-filter

  • Activated carbon and catalyst technology – combines two filter stages for odor and pollutant reduction.
  • Reduces unpleasant odors – for example from tobacco smoke, cooking, and other odor sources.
  • Supports the reduction of gaseous substances – activated carbon and catalyst act supplementarily on certain gaseous impurities.
  • Custom-fit replacement filter – specially suited for the WDH-660b and WDH-988b air purifiers.
  • Simple filter change – the existing combi-filter can be replaced without difficulty.
  • Compact design – filter element with a thickness of only about 1.1 cm.

Activated carbon filter against odors and smoke

Activated carbon has a very large internal surface area and can bind various gaseous substances and odor molecules through adsorption. This makes activated carbon filtration particularly suitable for assisting with unpleasant odors in indoor spaces.

The activated carbon filter is therefore a useful addition to the particle filtration of an air purifier. While other filter stages mainly remove airborne particles, activated carbon focuses in particular on certain gaseous components and odorants.

  • Supports the reduction of tobacco smoke odor
  • Helps with unpleasant cooking and food odors
  • Supports the reduction of various household odors
  • Complements the air purifier's particle filtration

Catalyst technology for pollutant reduction

In addition to activated carbon, the combi-filter features a catalyst component. This complements the adsorption effect of the activated carbon and is designed for the treatment of certain gaseous impurities.

This results in a combined filter system that can be used not only for classic odors but also for certain gaseous substances. The actual filter effect depends on the respective substance, concentration, air volume, and the condition of the filter.

Important regarding filter performance:
The effect of an activated carbon and catalyst filter depends on the type and concentration of the respective substances as well as on air throughput and filter condition. The specified filter performance is therefore not to be equated with the complete removal of all gaseous pollutants.

WDH-660b / WDH-988b filter against tobacco smoke

Tobacco smoke produces both fine particles and gaseous, odor-active components. The combi-filter for the WDH-660b and WDH-988b is specifically designed to reduce these odor-active and certain gaseous components.

The activated carbon can adsorb odorants, while the catalyst component supplements the filtering effect against certain gaseous compounds. For the most comprehensive indoor air purification possible, the interplay with the air purifier's other filter stages is crucial.

Reducing odors from cooking, fondue, and raclette

After intensive cooking, odors can linger in the indoor air for a long time. Intensive odors can arise especially when preparing fondue, raclette, roasts, or highly spiced dishes.

The activated carbon portion of the combi-filter supports the reduction of such odorants. This makes the filter particularly suitable for households where the air purifier is used regularly to help with odor problems.

Suitable for Aktobis WDH-660b and WDH-988b

The WDH-660b / WDH-988b combi-filter was specifically designed for the corresponding Aktobis air purifiers. Due to its precise shape, the existing filter can easily be exchanged for the new filter element.

Custom-fit replacement filter:
The combi-filter is intended for the Aktobis air purifiers WDH-660b and WDH-988b. Please check your air purifier model before ordering.

When should the combi-filter be changed?

The service life of an activated carbon and catalyst filter depends on usage and the level of indoor air pollution. In rooms with a lot of smoke, intensive odors, or increased pollutant levels, the filter may become saturated more quickly.

  • Check the filter regularly for dirt and condition.
  • Consider changing the filter if odor reduction decreases.
  • Check more frequently in cases of heavy smoke or odor exposure.
  • Change the filter according to the manufacturer's instructions.
  • Ensure the correct installation direction when changing the filter.
