Demand RC-48 Activated Carbon
To ensure total air filtration, there are several important
factors to consider. The first and most important factor is carbon
grade choice. Grade RC-48 carbon is derived from an ancient black
coal deposit found only in Western Australia. The particular
deposit is dated at over 250 million years old. After being
extracted, the RC-48 carbon is kiln activated at 1200°C in a
saturated steam atmosphere. It is this process together with the
coals unique density that causes the pores in the carbon to form.
This activation process makes the RC-48 carbon incredibly effective
for the filtration of organic particles and other airborne
materials. Because we use the purest available "activated virgin"
carbon and our granulated carbon has more surface area than
pelletized carbon, we can use significantly less carbon, thus
making our filters half the weight of competitive filters. Other
key factors that have been incorporated into Phresh® Filters are a
perfect combination of granulate size, carbon surface area and
carbon bed depth.

Competitive Filter Carbon
Installation is a breeze
The world's lightest carbon filters, at less than half the
weight of competitors, Phresh® Filters are easier to handle,
install, transport and remove.
Standard laboratory equipment
Phresh® Filters are used by labs, plant breeding, germplasms,
tissue culture and commercial greenhouses for their total airstream
filtration requirements. This professional-grade equipment is now
available to hobbyists world-wide. Control your growing environment
with the best filters available on the market.
More from less
CTC or "airstream removal tests" (ASTM D 3467-94) prove that our
carbon can absorb 108.3% of its own weight. This is how our small,
but powerful filters produce higher CFM and filtration at half the
size & weight of competing filters.
Extend your filter life
To get the optimum product life from your Phresh® Filter, it
should be used with the provided pre-filter sock. This pre-filter
sock catches the large dust particulates and foreign materials
which if allowed to come in contact with the carbon will ultimately
clog the outer surface of the carbon before total internal
saturation has been achieved. When this happens it unnecessarily
shortens the product life of the filter. It is recommended that the
pre-filter be machine-washed or replaced every six months.
Extremely dusty environments may require a more regular cleaning
program. Ideally, maximum air temperatures should be kept below 95°
F (35° C). Relative humidity should be kept below 75% at all times.
Remember, carbon will absorb moisture and will take up "space" in
the carbon particulate, reducing its life span.
There is no given limit to the life expectancy of RC-48 carbon
and your Phresh® Filter. The total life span can only be governed
by the amount of impurities absorbed by the carbon over time. The
rate of air movement through the carbon bed, total air impurities
and climatic conditions are the factors that determine the speed at
which the porous carbon granules reach maximum capacity. Phresh®
uses only RC-48 carbon. There is a global industry standard where
carbon is tested for "ID factor" and are given an "iodine number"
to American ATSM standards. ID factor can simply be explained as
the measurement of the amount of iodine in milligrams that can be
absorbed by a single gram of activated carbon. The higher the ID
factor, the higher the absorption rate. The average coal based
carbon is around 500 mg/g ID. On the other hand, RC-48 carbon has a
guaranteed analysis of 1050 mg/g ID. All this said, as a guide
rather than a rule, we suggest that a Phresh® Filters will last a
typical user around two years.
