It supplies body-friendly breathing air by removing impurities and odor, and moisturizing air for your breath.
The filter material has been refurbished from the current activated carbon dust dust-proof filter to the multiple layer electret filter, which improves the dust-proof performance by 20% and the pressure drop by 44%
Generation of negative ions
The action of forcing moisturized air through the restrictions of the bio-filter in effect crushes” the water molecule.
This crushing action releases negative electrons, which then attach themselves to oxygen molecules, creating negative ions of oxygen (Oe2). From 7000 to 8000 pcs/cc of negative ions ore generated by the bio-filter with each breath, a quantity similar to that produced by waterfalls of forests. Negative ions refresh, invigorate and increase alertness, improving diving pleasure and performance, especially when exercising vigorously.
As a moisturizer for your throat and trachea.
Rust and oil absorbed by New Electret filter!!
A diving cylinder can retain small particles of dust, and oil residue.Inhaling these contaminants can be harmful to your body.New electret filter cartridge employed in the bio-filter and bio-micro efficiently removes impurities including rust, dust and oil.

20% Improvement of collecting dust efficiency over the conventional cartridge.
The filter material is determined through measurements and evaluations of dust collecting performance of fine particles from 0.5um to 5um.The high dust collection rate is achieved by the effect that the PM2.5 (the harmful particles of 2.5μm or less of ) is, of course , also oil mist distributed in the 0.5 ~ 5μm, are electrically be attracted by the electrostatic force of the electret fiber.Nowadays this electret filter is commonly used with medical filters, exclusive air cleaners and automobile premium air conditioners.
With the new filter cartridge, the dust collection rate is further improved by 20% even compared with the conventional filter which also performs high dust collection rate with adoption of exclusive filter materials. No longer the conventional activated carbon filter is unnecessary. The new filter cartridge adsorbs whole fine particles, and block the most of rust and oil.
(Measurement condition: Count number of particles by the particle counter of each particle size of the air which is filtered by the filter cartridge installed in the bio-filter.)
44% reduction of the pressure drop.
In general, the dust collection filter becomes a fine meshed as increase its performance , in proportion the increase of its performance, it will increase the pressure drop (resistance of the air flow). However, in the new electret filter cartridge , despite a 20% improvement of the dust removal performance compared with conventional models , it also reduce the pressure drop successfully by 44%. . This helps greatly to reduce the breathing resistance in extreme conditions , such as severe breathing in great depth , directly involved in the relief of mitigation and air consumption of fatigue.
(Measurement condition: Air flow 30L/min., At atmospheric pressure, the cartridge installed in the bio-filter)

The Bio-filter needs overhaul at every one year or 100 dives.
Cleaning of check valve
When washing the bio-filter for overhaul etc., please do not wash the check valve, shown in the photo on the left, with acid or organic solvent. Because of the valve is made of urethane resin, it may deteriorate remarkably and cause air leakage.
Also, please replace the parts as soon as deterioration such as cracks on the surface is seen.
Time to replace the water filter.
The water filter (Moistureizer pad) is a expendable supplies.Please replace it every 50 to 100 diving, or replace immediately when breeding traces of bacteria or dirt adhered from fingers can been seen.It does not contain any agent such as an antimicrobial agent in a sponge as it preserves water to moisturize beathing air. Therefore depending on handling and storage condition, the breeding traces of bacteria or dirt might be seen even in a few diving.It is recommended to always carry and posses a spare water filter.
Time to replace the electret filter cartridge.
The electret filter cartridge is a expendable supplies. Usually replace it every 20 to 50 diving, or when the adhesion of dirt and oil can be seen on the surface.It is also recommended to always carry and posses a spare activated carbon filter cartridge.
