Chemical Compatibility of the Pall QPointTM
Filter Capsule - Rose Outlet with Systemic
Water Treatments
QPoint - More than Filtration
1.0Background
A
wide variety of systemic chemical treatments are used globally as part of a multi-barrier approach to control microbial
contamination within water supplies of hospitals and other large public and private buildings. Such treatments are
often used in conjunction with point-of-use water filters. Therefore point-of-use water filters need to be compatible with
systemic chemical disinfection.
T
he Pall QPoint Shower Water Filter Assembly consists of a chromed reusable Docking Station, designed to fit
all standard shower hose outlets, and a disposable Filter Capsule with rose outlet. The Pall QPoint Filter Capsule
(Figure 1) is indicated to remove bacteria, protozoa, fungi and particles from the water supply for up to 2 calendar
months (maximum 62 days). The Filter Capsule is supplied sterile.

ests to confirm compatibility of the QPoint Filter Capsule with common systemic chemical treatments are documented
T
within this report. The Docking Station can also come into contact with surface disinfectants and specific compatibility
with these chemicals is documented in report 160127.2WGL.
ompatibility testing involves subjecting Filter Capsules that have been exposed to a selected chemical treatment to a
C
non-destructive integrity test which is correlated with bacterial retention.
Tests to demonstrate compatibility of the QPoint Filter Capsule with active chlorine (continuous treatment at <7 ppm
and/or 1 hour shock treatment at 100 ppm), pH >12 and peracetic acid have been conducted and are summarised.
2.0
Active Chlorine
2.1
Shock treatment with active chlorine (100 ppm)
Five QPoint Filter Capsules were soaked for 1 hour in a solution of sodium hypochlorite containing 100 ppm
active chlorine at a temperature of 22 ± 2 °C. Following the test period, all 5 Filter Capsules were subjected to
a non-destructive integrity test. Testing was conducted on Filter Capsules with a jet outlet that share the same
materials and processes of construction and sterilizing grade filter media as Filter Capsules with a rose outlet.

All 5 Filter Capsules passed the integrity test (Table 1) and no visual abnormalities were observed.
2.2
Continuous treatment with active chlorine (<7 ppm) followed by shock treatment with active chlorine for (100 ppm)
Five QPoint Filter Capsules were soaked in a solution of sodium hypochlorite containing <7 ppm
active chlorine at a temperature of 22 ± 2 °C over the life of the product. After 31 and 62 days,
the Filter Capsules were subjected to a non-destructive integrity test. At the end of the continuous
treatment period, the QPoint Filter Capsules were soaked for 1 hour in a solution of sodium
hypochlorite containing 100 ppm active chlorine at a temperature of 22 ± 2 °C and again subjected
to a non-destructive integrity test. Testing was conducted on Filter Capsules with a jet outlet that
share the same materials and processes of construction, and sterilizing grade filter media as Filter
Capsules with a rose outlet.

All 5 Filter Capsules passed the integrity test (Table 2) following each treatment period and no visual
abnormalities were observed.
Pall QPoint Filter Capsules are therefore considered to be compatible with continuous treatment with active
chlorine at <7 ppm over their indicated life of 62 days and/or shock treatment of 100 ppm active chlorine for
1 hour.

Shock treatment with pH > 12
Five QPoint Filter Capsules were soaked for 1 hour in a solution of sodium hydroxide (pH > 12) at 22 ± 2 °C.
Following the test period, all 5 Filter Capsules were subjected to a non-destructive integrity test. Testing was
conducted on Filter Capsules with a jet outlet that share the same materials and processes of construction and
sterilizing grade filter media as Filter Capsules with a rose outlet.

Shock treatment with peracetic acid (1000 ppm)
Five QPoint Filter Capsules were soaked for 2 hours in a solution containing 1000 ppm peracetic acid at 60 ± 2 °C.

5.0Conclusions
Pall QPoint Filter Capsules are compatible with continuous systemic treatment with active chlorine at <7 ppm over their
indicated life of 62 days and/or shock treatment of 100 ppm active chlorine for 1 hour. These Filter Capsules are also
compatible with pH >12 for 1 hour or 1000 ppm peracetic acid for 2 hours
