Heavy-Duty Deodorizing Filter

Heavy-Duty Deodorizing Filter

Catalytic Activated Carbon, Activated Carbon, Zeolite, Heavy-Duty Deodorizing Filter



Odor molecules are absorbed by nano-size micropores. This is particularly effective for removing nitrogen-based odors.

Activated Carbon

A special surface agent that improves absorption of odors. Absorbs a wide range of odors including nitrogen-based, aldehyde-based and acid-based odors.

Catalytic Activated Carbon


Absorbs odors while the catalyst oxidizes, in particular, sulfur-based odors to components with minimal smell. Effectively absorbs a wide range of odors.

Reduces the Seven Main Odor Components

Odors reduced include unpleasant room odors composed of the four main components*.


Ammonia (Pet odors, etc.), Trimethylamine (Smell of rotten fish, etc.)


Acetaldehyde (Smell of tobacco, etc.), Isovaleraldehyde (Smell of grilled meat, etc.)


Acetic Acid (Cooking smells, etc.), Isovaleric Acid (Body odors, smell of laundry drying indoors, etc.)


Methylmercaptan (Smell of rotten vegetables)

*Results of a deodorizing performance test performed in a 1㎥ test chamber with single odor components. Tested by Hitachi. Deodorizing performance differs depending on the space where the unit is actually used.

Reduces Formaldehyde (VOCs)

The results of a test performed by Hitachi conforming to the standard (HD-103) set by the Japan Electrical Manufacturers' Association showed that in an approx. 10㎡ room, the initial formaldehyde concentration of 2ppm was reduced to 0.08ppm. The acceptable level of formaldehyde in a room in the guideline of the Ministry of Health, Labour and Welfare and the advised level of WHO is 0.08ppm or lower.

99% of 0.1 to 2.5µm Particles Caught – Ready to Remove PM2.5 Particles

Not taking into consideration new particles from outside entering a room during ventilation or by some other means. PM2.5 refers to ultrafine particles smaller than 2.5µm. The removal of particles smaller than 0.1µm has not been verified. In addition, not all harmful substances in the air can be removed. This is the effect in a sealed 32㎥ space, not the effect in an actual living space.

Low Noise Operation

Low Noise Operation

During Silent airflow operation, the noise level is less than 15dB, so it won't disturb you when sleeping.

  • Noise level differs depending on the model.

In accordance with the JEM 1467 standard. In a test of dust collecting and deodorizing capacity with 5 cigarettes smoked per day, the period of time after which air purifying took twice as long as the initial time, and the odor removal rate became
In a test performed with humidifying operation of 8 hours a day and washing with tap water once a month, the periods of time after which level of humidification became half the initial level.
Since there are theoretical values, under actual conditions of use, replacement may be required after a shorter period of time.
