Filtered water on tap for drinking and cooking

The Double Imperial Plastic Undersink Drinking Water Filter System gives you unlimited filtered water. Perfect for drinking, for use in coffee machines and kettles, cooking and washing vegetables and salads.  Use to water indoor plants too.

The Double Imperial Unit made from quality food grade plastic only requires basic level DIY.  You can easily fit it yourself.  Some do use a plumber and if you choose to do so it should be an inexpensive job due to the nature of the installation.  This unit fits in a standard kitchen cupboard and comes complete with a standard tap.

Filter options

The 2.5″ x 10″ CeraMax Candle OBE maintains a high level of filtration.  It will remove bacteria, Chlorine, cysts, heavy metals, lead, particle, trace organics and organic chemicals.  See TAB for more information

The 2.5″ x 10″ Ecosoft Carbon Block Filter is a good basic filter. It will remove chlorine, particles down to 10 microns and organics such as pesticides, herbicides and oestrogens but not bacteria.  See TAB for more information.

The 2.5″ x 10″ Ecosoft (GAC) Granulated Activated Carbon Cartridge is a good basic filter. It will remove chlorine and chlorinated by-products, concentrations of heavy and non-ferrous metals, oil products, pesticides and phenols, improving the colour taste and odour.  See TAB for more information.

The 2.5″ x 10″ (GAC) Granulated Activated Carbon Cartridge is effective at reducing chlorine and improves colour, taste and odour.  Due to its granulated construction is probably better when only low pressure is available.  See TAB for more information.

The 2.5″ x 10″ Limescale Reduction Cartridge which is specially made, has the ability to reduce limescale in our tap water.  Chlorine, bad taste, turbidity, trihalomethanes, particles and organic contaminants as also reduced.  See TAB for more information

The 2.5″ x 10″ Fluoride Reduction Cartridge will remove up to 75% of all fluorides including synthetic fluorides which are added to municiple water supplies.  See TAB for more information

Should you require the removal of additional contaminants then a Triple Undersink unit might be better for your specific needs.

Overall dimensions 350 x 220 x 120mm plus consideration for necessary pipework installation and changing filters.

Imperial Pre-filter

Large particle removal

The Imperial Pre-filter cartridge removes larger particles down to 20 microns protecting the ceramic Ceramax, Aquametix or 5 Micron carbon block and increasing the flow rate.

Replacing the filters

The Imperial Pre-filter should be replaced every six months, it is recommended these filters are used for no longer than 12 months. Take a look at our Filter Replacement Service tab for peace of mind.

Independent quality control testing

The Imperial Pre-filter cartridge is manufactured with ISO9001: 2000 Quality Assurance. WRAS (Water Regulatory Advisory Scheme) and The Water Quality Association use a very strict set of criteria to continually monitor the filter candles and performance of the undersink units. It also has been independently tested by NSF to Standard 42.

5 Micron Carbon Filter

 

Trace Organics Removal

One of the main properties of activated carbon is that it will remove organic compounds. Additionally the activated carbon in our filters has an affinity for hormone based steroids such as oestrogens so should help to remove them to some extent, testing is in it’s infancy so we are currently unable to make an accurate claim to the extent of the removal.

 

Insecticides – >85%
Herbicides – >85%
Phenols TCP – >50%
Polyaromatic Hydrocarbons – >95%
Trihalomethanes – >50%

 

Inorganics Removal

Free Chlorine – >97%

 

Replacing the filters

The 5 Micron Carbon filter should be replaced every nine months for four people and every twelve months for one to two people. Do not use for longer than twelve months without replacing. Take a look at our Filter Replacement Service tab for peace of mind.

 

Independent quality control testing

The 5 Micron Carbon filter is manufactured with ISO9001: 2000 Quality Assurance. NSF (National Sanitation Foundation), WRAS (Water Regulatory Advisory Scheme) and The Water Quality Association use a very strict set of criteria to continually monitor the filter candles and performance of the undersink units.

Healthy House®  CeraMax Filter Information

The cartridges are based on a Imperial Ceramic pre-filter shell.  Inside the ceramic shell is a post-filter block carbon insert which is manufactured by combining powdered carbon blends with lead scavengers to form a tightly packed matrix.  The cartridge is open both ends for easy installation into standard 10″ housings.

 

Pathogenic bacteria – Tests performed by AlControl Laboratories

 

Cholera – >99.9999%
Typhoid – >99.9999%
Salmonella – 99.9999%
Serratia – 99.9999%
E.Coli – 99.9999%
Feacal Coliform – >99.9999%

 

Cysts

Cryptosporidium – 100%
Parvum – 100%
Giardia Lamblia – 100%

 

Sediment – 0.8 micron Absolute Rated; 0.2 – 0.45 micron with a filtration efficiency of >99.93% (based on tests by IBR Laboratories).   This is significantly more efficient than the Doulton Ultracarb filter, which can only claim a nominal filtration efficiency at 0.5 micron.

 

Plastic Particles/Fibres in Drinking Water

In a study in 2017, 72% of the water samples tested in the UK, Germany and France contained plastic particles/fibres. Within the study of tap water, it was likely that the nanoparticles were present alongside the fibres, but this was not measured. Worryingly, once the particles are in the nanometre range, they can penetrate cells and possibly organs. This investigation caught particles of more than 2.5 microns in size, which is 2,500 times bigger than a nanometre.

Herbicides
Organic solvents

 

Volatile Organic Chemical Compounds

Lead Removal

Lead is seldom found naturally in domestic water supply but can result from the dissolution of lead pipes which may still be in use in old water systems.  The Zeolite metal ion reduction medium in the CeraUltra element effectively reduces the lead content in drinking water.

 

Trace Organics Removal

One of the main properties of activated carbon is that it will remove organic compounds. Additionally the activated carbon in our filters has an affinity for hormone based steroids such as oestrogens so should help to remove them to some extent, testing is in its infancy so we are currently unable to make an accurate claim to the extent of the removal.

AquaMetix® Carbon Filter

Removes chloramine and heavy metals

The AquaMetix® Imperial Carbon filter has been designed to reduce chloramine, chlorine, lead, other heavy metals, chemicals and fluoride in a single stage filter.  The unique technology of AquaMetix® means the filter is able to remove the ammonia left behind by other ‘chloramine’ rated blocks. The carbon filter combines at least 2 types of activated carbon and proprietary Zeolite minerals that  are structurally bound with polymers in a highly porous filter block.

What is chloramine?

Chloramine is a combination of chlorine and ammonia and is used to disinfect water supplies. While chlorine dissipates and evaporates into the air relatively quickly, chloramine is more stable and will last longer in the water system. Chloramine cannot be removed by boiling, distilling or by standing uncovered. The EPA states there are NO dermal (skin) and NO inhalant (respiratory) studies on chloramines when it is used to disinfect water for drinking. The AquaMetix filter will remove chloramines.

How it improves water quality

The AquaMetix® filter will improve taste and odour and will absorb:

  • organic and inorganic substances – pesticides, herbicides and oestrogens

  • chlorine

  • chloramine – combination of chlorine and ammonia

  • fluoride

  • VOC’s and other chemicals

  • A reduction in copper, glyphosate, mercury, nickel, silver, trihalomethanes and zinc

Independent Testing

NSF 42 tested for Chemical Reduction Fluoride

NSF Standard 42-2011 Chloramine Reduction

NSF Standard 53 Lead Reduction

Replacing the filters

The Imperial Pre-filter should be replaced every nine months. Do not use for longer than twelve months without replacing. Take a look at our Filter Replacement Service tab for peace of mind.

NanoCeram-LR Series Pleated Filter

This filter is to be used in the final housing.

A very high specification NanoCeram-LRTM Series pleated filter has been designed to replace standard pleated filters but with increased capacity and efficiency down to 0.2 micron.

The NanoCeram-LR SeriesTM directs water flow through the two pleated layers of Argonide’s patented media and combines high efficiency and high dirt holding capacity while providing superior flow rates at low differential pressures.

These very efficient filters allow improved efficiency and increased capacity and fits into existing filter housings. The NanoCeram-LR has a single pore size of 2micron for all applications and effectively removes particulates down to 0.2 micron

Very effective in the presence of salt and high pH levels.  The pleated structure allows for very high flow rate while dealing with submicron particles such as virus, bacteria, metals, metal oxides and other difficult to remove colloidal materials. Colloidal materials are used to incorporate additional properties to a solution. A colloid can be defined as a microscopic substance that is suspended in another medium usually a liquid. Colloidal materials can remain evenly distributed in the solution without settling to the bottom or becoming dissolved.

All LR-19 components are manufactured with materials that meet FDA requirements 21CFR177.1520 for direct food contact applications
