If you own your own reg assembly, you could add a
Bio-Filter Regulator Moisture System to it:
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 everywhere
can enjoy the benefits of this bio-filter by simply
fitting it to any existing regulator
Many divers are not aware of the difference between
compressed tank air and air they breathe on the surface
Compressed tank air is dry (0 1% humidity) and 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, reduced post-dive headaches,
increased bottom time, and reduced 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 problems associated with dry tank air by
replacing 30-70% humidity back into the tank air the
diver breathes It also filters out trace particles of
dust, rust, and odor
The Apollo Bio-Rilter 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.
