Application and Pre-Treatment Requirements
Sediment Pre-Filter
For all Aquasential Whole Home PFAS Filter systems, Culligan recommends the installation of a cartridge type sediment pre-filter with
a minimum 50-micron rating immediately prior to the system to prevent sediment and particulates from entering and accumulating
in the filter media� If the water supply to be treated has a significant amount of sediment and particulates in the water an automatic
backwashing filter system should be installed� Failure to follow this guideline could result in loss of water pressure and the need to
prematurely replace filter media� It is recommended to consult with Culligan International for application assistance if needed�
WARNING!
Outside faucets and irrigation systems
A substantial amount of water can be used for outdoor purposes and lawn irrigation compared to the
daily volume required for domestic use inside a home. Water lines supplying water for outside uses
should be bypassed from the PFAS Filter system to extend the media life unless treated water is required.
Water Quality
The quality of the feed water to the Aquasential PFAS Filter system can have a significant impact on PFAS reduction
and the media life� Refer to the specifications section in this Owners Guide for recommended guidelines�
Municipal Water Supplies
Municipal water suppliers are required by the US EPA to provide annual Consumer Confidence Reports (CCR) that
summarizes the water quality they provide� These reports can be found on the water supplier’s website and are a good
source for basic water quality information� If a municipal water source supplies chlorinated water, the Aquasential PFAS
system will reduce the chlorine level*
NOTE! *The Aquasential PFAS System is not certified for chlorine reduction.
Well Water Supplies
The water quality of every well is different even in the same geographical area� A full water analysis is recommended
for well water applications to ensure the water quality meets specifications�
Problem Water Applications
For well water sources that have water quality issues related to odor, discolored water, or visual evidence of microbiological
growth, the problems should be corrected prior to installing the Culligan Aquasential PFAS Filter system�
