Filtr-Cleer ®
The Filtr-Cleer Automatic Water Filter is capable of reducing particulate matter down to 10 microns
particle size. It will not remove color, organics, colloidal turbidity or dissolved solids. Some
applications follow:
• Reduction of suspended matters in any water system.
• Reduction of particulate matter, such as clay, mud, etc.
• Prefiltration of oxidized iron ahead of an automatic or manual softener.
• Reduction of light sand.
NOTE: If sands cannot be reduced from the Filtr-Cleer tank during backwashing, a sand trap
should be installed.
• After the retention tank when a Cul-Cleer ® system is used to correct hydrogen sulfide or colloidal
suspension problems.
The quality and number of gallons filtered water between backwashes will depend upon the amount,
type, and size of the particulate matter being filtered. If a water sample is sent to our laboratory,
where application of a Filtr-Cleer unit is contemplated, write “Filtr-Cleer Analysis” on the sample
tag. Send an additional sample of water for a standard water analysis. The laboratory will test for
Nephelometric Turbidity Units (NTU) and suspended solids (mg/L). The sample will also be filtered
through 10 micron filter paper and NTU run on a filtered sample. If the NTU of the raw water exceeds
150, suspended solids exceed 150 mg/L or the filtered water through the 10 micron filter paper is of
an unacceptable quality, a Filtr-Cleer filter may not be applicable. As a guide, the U.S. Public Health
Drinking Water standards states the turbidity should not exceed 1 NTU. The exact number of gallons
filtered between backwashes cannot be given because of many variables.
Cullar ® Filter
Medallist Water Filter with Cullar Media will reduce chlorine taste and odor and other common bad
tastes and odors, and will also reduce most objectional organic colors. It will not remove hydrogen
sulfide. It is important to note that whenever the cause of an objectionable taste or odor has not been
established, Health Authorities should determine if water is safe to drink. If bacterial contamination is
present, a Cul-Cleer system is indicated. Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system.
Cullneu ® Filter
Medallist Water Filter with Cullneu Media will neutralize slightly acid water (pH of 5.8 - 6.2) and thus
help to prevent unsightly brown or green stains due to corrosion of household plumbing. If the pH is
from 5 to 6, one part of Cullneu C media should be mixed with 5 parts of Cullneu media to provide
additional neutralizing capability. If the water to be treated has a pH less than 5, a high hardness, or
a high carbon dioxide level, Cullneu may not be applicable; a solution feeder should be used. Since
Cullneu adds hardness, it should be used prior to a softener.
In order to size and apply the equipment correctly, a complete analysis of the water supply should be
obtained. This can best be accomplished by contacting your local Culligan dealer, who will be able
to test the water supply right at the site, or arrange to have one or more water samples sent to the
Culligan laboratory for a more detailed analysis.
