Filterpure® and Steriflo® Peace of Mind
Water is essential for life, a healthy lifestyle is promoted with water free from contamination and impurities.
For clean, safe and fresh tasting water in unlimited volumes right in your home, a simple three process system will ensure a reliable supply, for your peace of mind.
FILTRATION
Water can be discolored and tainted by particles such as: dust, rust, sediment, hair, algae, and parasitic cysts (Giardia & Cryptosporidium). Water is swiftly cleared of these particles once passed through an appropriate Filterpure cartridge, rejuvenating the sparkle in truly clean water. Ideally, a coarse and then a fine cartridge will be installed together.
DISINFECTION
Microscopic living organisms can thrive in water such as: bacteria, mould, viruses, yeast, and parasitic cysts (Giardia & Cryptosporidium). Exposure to Ultra Violet light is a safe and effective way to neutralise these unhealthy organisms in your water. Davey Steriflo® UV units are ideal for domestic water disinfections.
PURIFICATION
Dissolved impurities that affect the taste, odour and safety of your water can include: chlorine, pesticides, herbicides, and solvents. Filterpure cartridges containing activated carbon absorption media are an effective tool to purify water of these unwanted substances. Purification is most effective at the point of use, like the kitchen tap. Bacteriostatic cartridges inhibit the growth of organisms within the element fabric.

Davey Filterpure® St Steriflo® systems offer clean, safe and healthy water, without using chemicals for one tap or for the entire house. Wherever you get your water, be it mains water, rainwater, bore or even dam water, there is a Davey Filterpure and Steriflo system for you.
Design of your Water Process
The size of housing is determined simply by how many taps or appliances you want to provide water to ie. regular 10" for a single tap and jumbo 10" and 20" for anything larger - up to whole of house. A clever installation will have two jumbo 10" or 20" cartridge filters installed on the main cold water line entering your house followed with a UV disinfection system. Drinking and cooking taps are then protected with a standard 10" purification filter.
The ideal sequence of elements would start with a coarse 20 micron PP cleanable element to remove large particles and increase the life of secondary elements. A second, finer PS element of 1 or 5 micron as stage two will really start to produce pure clear water. For individual outlets such as kitchen taps a smaller purification filter with activated carbon and a bacteriostatic media will ensure that you have great water and peace of mind.

Cartridge Element Types:

PLEATED POLYESTER (PP SERIES)
Pleated polyester cartridges offer reduced operating costs for many applications as the pleated construction allows them to be rinsed clean and reused. In addition the cartridges have a high surface area and can handle higher flows than disposable depth cartridges. The availability of Jumbo sized PP cartridges means that high flows can be economically filtered. The 20 micron is an outstanding pre filter, easy to clean with a high dirt holding and flow capacity.
SPUN POLYPROPYLENE (PS SERIES)
These are pure polypropylene with no filters, binders, adhesives or surfactants, so are ideal for food and drinking water use and any applications where high purity is important. The melt blown fibres give a graduated pore structure allowing for depth capture in the matrix. Generally used as a second stage for finer micron filtration.
PURIFICATION CARTRIDGES
Activated Carbon purification cartridges are typically for the removal of taste, odour, chlorine, pesticides, and other organic chemicals. They are best used at the final point of use stage in your water process. Filterpure cartridges need to be replaced and /or cleaned at regular intervals to ensure they are performing correctly.

Note: Cartridges marked * are suitable for cyst reduction, cartridges marked # are suitable for cyst removal. Davey recommend UV disinfection as part of a water treatment programme.

*Maximum flow is for clean and clear water - pre filtration and post filtration may be required depending on installation.
