Description:

SAFE... CLEAN .. Natural air from any scuba regulator, 
Apollo announces the new bio-filter for all scuba diving regulators. The bio-filter assures clean, moisturized air for comfortable and safe diving. Scuba divers anywhere can enjoy the benefits of the bio-filter by simply fitting it to any existing.
Many divers are not aware of the difference between compressed tank air and air they breath on the surface. Compressed tank air is dry (0.1% humidity) this can cause severe discomfort, dry throat, or 'cotton mouth.' More seriously, dry air dries lung tissue and increases the risk of decompression sickness.
Other benefits include easier pressure equalization, reduces post dive headaches, increases bottom time, reduces general fatigue.
For scuba diving it is granted that the supply of ample air comes first, but no less crucial is the quality of air. Moisturized air is essential to pulmonary respiration and for comfortable, safer scuba diving. The bio-filter eliminates the problem associated with dry tank air by replacing 30-70% humidity back into the air a diver breathes. It also filters out trace particles of dust, rust, and odor.
The bio-filter is perfect for all scuba divers seeking clean, moisturized air - this includes the adventurous travel diver diving in locations where purity with air fills is questionable or the weekend diver who seeks comfort and additional safety.
