1.2 How a Magnetic Filter
Through a combination of innovative
product design and a clever use of
the laws of physics, water is guided
through the components of the Mag-
One to achieve ma ximum filtration
with each pass of the circuit.

Water enters the filter through our
ingenious diverter block and then
passes into the magnetic filter 500ml
capacity pressure drop chamber.

Here, particulate is forced through
the non ferrous filter and down
towards the magnet. Through a
process of natural convection, water
then circulates back to the top of
the filter and back into the system
leaving all magnetite and particulate
debris captive at the base of the
filter’s magnetic core.

All system contaminants are then
easily removed during servicing
by isolating the Mag-one from the
system and removing the magnet
from the screw cap at the top of
the pot then opening the drain
valve, removing the majority of
contaminants within the pot in
