Pre-Filter for Fluoride Removal - 10" Activated Alumina Cartridge

Suitable for use with Delphi, Alphion, Melody and Venus Alkalisers

Capacity is 2,500 litres (approx. 6-8 months)

Requires Pre Filter Housing

The normal BioStone Filter removes up to 42% of fluoride the fluoride pre-filter removes up to 70%, and together they remove a total of up to 83% of the fluoride from your water.

Installs inline between your water source and your ioniser.
'Quick Fit' fittings mean no tools required. Just cut your present in-line hose where you want the pre-filter to sit, and connect to the pre-filter - a five minute job and then no more fluoride.

How it Works
Activated Alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square metres/gram. The compound is used as a filter of fluoride, arsenic and selenium in drinking water.

One of the effects of using this filter medium is that it may leach some aluminium in the water even though it removes the fluoride.

So when using Activated Alumina you should always get at least a two stage water filter. The second stage will contain a form of activated carbon that can take care of any aluminium problem.

Provided you maintain them with correct replacement intervals, the Jupiter BioStone will filter any possible aluminium eluted from the fluoride filter.
