What you get
Product Description

Replacement 0.1 Micron MicroFiltration Filter Cartridge for Canal Boats, Caravans and other uses

This is a very powerful sub-micron filter that filters out anything bigger than 0.1 microns.

One micron - aka a micrometer - is a unit of length equal to one-millionth of a meter - ie one-thousandth of a millimeter. (Micron is often used as a term of measurement in water filtration).

To give you an idea: a human hair is an average of 100 microns in diameter.

The smallest micro-organism, Mycoplasma can be as small as 0.3 microns

Anything bigger than 0.1 microns will be blocked by this filter.

This filter will protect against bacteria that might build up in your canal boat water tank - provided you've filled it with mains / potable water.

Important Note some viruses are smaller than 0.1 microns so don't use this to filter any raw water - see below.

What is Ultra Filtration

This is the ultimate in traditional barrier filtration - ie where particles cannot get through a mesh / barrier / wall.

Ultrafiltration is similar to nanofiltration, microfiltration, and reverse osmosis in that it is another type of membrane filtration whereby a semi-permeable membrane filters water with only one screen filter or barrier filter.

It is a self-contained, all-in-one way to purify water. It doesn't require any chemicals.

(It can also be used as a pre-treatment for reverse osmosis).

Ultrafiltration used to be primarily used for desalination but has become increasingly used to filter particulate materials, bacteria, and other microorganisms.

It results in very high water quality, without using chemicals, that is free of all the usual contaminants, and microorganisms found in raw water. (Raw water is any non-treated water from lakes, rivers, ponds, canals and rainwater).

What this UltraFilter Removes

  • Suspended solids
  • Bacteria
  • Some viruses (NB not all)
  • Endotoxins and other pathogens
  • Natural organic material
  • Silt

Important Note some viruses are smaller than 0.1 microns so don't use this to filter any raw water - see below.

Benefits of Ultra Filtration

  • Highly compact (eg much smaller than Reverse Osmosis)
  • Chemical-free process (No flocculate, coagulant, disinfectant or pH adjusting required)
  • Consistent particle and microbial removal (ie performance doesn't decline during filter life)

Get an Extra tap and Water Connection

Please note this is a standalone cartridge.

It does not include a tap or a connection to the water supply.

If you need those, no problem!

When you add this cartridge to your basket you will see an option to combine it with this standard undersink water filter system

To combine these, all you need to do is simply cut the supplied tubing - that comes with the extra undersink water filter system - with scissors and insert the ultrafiltration cartridge "inline" into the system.

You wilol also see an option to choose an extra three way tap instead of using the standard small water filter tap which comes with the undersink kit.

Can I Filter Raw Canal Water With This Filter?

No it should not be used to filter raw canal water because some viruses are as small as 0.02 microns.

Sewage-contaminated water can contain viruses which can lead to diseases like meningitis, hepatitis and gastroenteritis).

To remove these viruses you would need to consider using a Reverse Osmosis system. These can have a pore size of 0.0001 microns.

But even with an RO filter, if you wanted to filter raw canal water (ie any raw water which is likely to be badly polluted), to be totally safe, you'd also need to combine it with an Ultra Violet filter and several pre-filters (including this 0.1 micron Microfiltration cartridge).

UF membrane manufacturers classify their UF product as having a
specific Molecular Weight Cutoff (MWC). This is a rough measurement of
the size of contaminants removed by a given UF membrane.

A 100,000 MWC UF membrane means that when water containing a given
standard compound with a molecular weight of around 100,000 daltons is
fed to the UF unit, nearly all of the compound will not pass through the membrane.
