Step 1
Whole House Product Selector
What type of supply do you have?
The first thing to establish is what sort of water supply you have - essentially whether it's treated portable water from one of the water companies, or taken from a well or river on your land. If it's the latter, you may have to add a UV filter to treat your incoming water for micro-organisms, such as those known as protozoa.
As your water supply is private, not from a water company, we recommend that you contact us to discuss your requirements.
Step 2
Do you know your flow rate?
To specify the right size of system for your needs, we need to have a rough idea of your peak water flow rate. You may find this on your water bill, or simply take your average day's water usage and divide it by two (corresponding with the two peaks of usage in early morning and later in the evening), and that figure is your appoximate flow rate.
Enter your flow rate:
Recommended housing size:
Our systems are available in two sizes depending on your flow rate. If you don't know your flow rate, don't worry - our calculator will assume you need the larger size for now.
Step 3
Select number of housings
You can choose whether you want a 2 or 3 housing system. The amount of space you have available and if you want to include a dedicated sediment filter and/or remove various different contaminants may have an impact on your decision.
Step 4
Do your require a dedicated sediment filter?
A dedicated sediment filter’s purpose is to be the first filter to engage with your water and protect the other filters from being impacted by sediment. We always recommend including one, but the choice is yours.

Finerfilters Salt Free Water Softener Alternative – Limescale Prevention – 10″ Jumbo Replacement Cartridge
£89.99Product Description
Finerfilters Salt-Free Water Softener Alternative - Limescale Prevention
10" x 4.5" Jumbo Replacement Cartridge
Hard water is naturally occurring, but the scale it leaves behind can have a very detrimental impact on the efficiency and life of your plumbing and appliances, such as heaters and boilers, as well as inhibiting the formation of soap suds, meaning you use more detergents and soap when washing clothes or bathing.
Although traditional salt-based water softener systems do remove the minerals which are attributed to limescale build-up, they also remove the minerals that are essential and healthy for us such as calcium & magnesium and leave behind large amounts of sodium which means your incoming water supply is now undrinkable.
This is usually remedied by creating two water feed lines, one salt softener treated line and one untreated line. This means more work for your plumber, increasing the cost of installing the system which you likely paid a lot of money for already.
Not only are they expensive to install they also require constant rejuvenation of salts and chemical cleaning in order to maintain their performance, which also comes at a cost both financially and environmentally.
Finerfilters’ Limescale Prevention Water Filter system uses an advanced filtration process known as Template Assisted Crystallization (TAC) which prevents the formation of limescale by converting those pesky scale causing hardness minerals into inert microscopic crystals via a catalytic reaction in the water being treated.
These crystals once created travel through the plumbing system and appliances in colloidal suspension - they do not stick to surfaces, which prevents the formation of limescale deposits so they’re no longer able to bond and stick to your pipes or appliances.
This system requires no electricity, doesn’t waste water by back-washing or regeneration, uses no salt or other chemicals, requires virtually no maintenance (the filter media should be changed after 1 year in foodservice applications and every 2 years in domestic applications), retains healthy minerals and adds nothing to the drinking or wastewater.
The media we use has been tested by independent laboratories and researchers and has a proven 99.6% rate of effectiveness (the only non-salt technology to do so) and can even help to reverse some of the scale build-ups which is already eating away at your existing systems such as heaters and boilers, allowing them to work more efficiently and use less energy meaning it can also help to reduce your electricity bills.
The benefits of using one of our Finerfilters Salt-Free water softener systems are numerous;
Multi-Purpose
- Feedwater needs less contact time than softener resin, so smaller systems can be used, making it perfect for use as a whole house system even if you have limited space and can also be used to protect systems such as instant hot water taps and coffee machines.
- Can be used in commercial applications by simply adding more media to the housing vessel.
- Our systems can also be used on water supplies obtained from wells or boreholes however heavy metals such as iron and manganese and excess sediment should be filtered out before the unit.
Environmentally Friendly
- Our systems not only prevent limescale formation but over time will gradually work to remove existing scale build-up whereas a traditional softener will only prevent new scale formation. This will in turn reduce energy consumption and improve the efficiency of your water heaters and boilers, essentially lowering energy bills.
The longer you use the system, the more apparent this becomes meaning your appliances stay functional for longer.
- Requires no salts, cleaning or use of chemicals or regeneration agents which can be harmful to the environment and increase the running cost.
- Doesn’t require backwashing of salts, so no additional connection to a drain line or wasteful usage of water.
- No brine discharge meaning our systems can be used in areas where conventional water softeners are banned or regulated.
Low-Maintenance
- Installation is a simple one-time process requiring only an inlet and outlet either at the Point-of-Entry (PoE) in a whole house system or Point-of-Use (PoU) to protect specific appliances such as coffee machines.
- Vastly improved filter lifespan and low maintenance; the media only needs to be replaced after 1 year in foodservice applications and every 2 years in domestic applications.
- The life expectancy of the housing system itself is much greater than a traditional softener system as it has no moving parts and is made from high-grade BPA free plastics.
Healthier
- Our systems do not remove any of the beneficial minerals that are carried by water, whereas a traditional water softener will.
Not only that, but our systems also do not add anything to your water supply whereas a traditional softener system adds harmful levels of sodium, making your water undrinkable. - Our salt-free water softeners do not remove chlorine which is added to municipal water supplies, but the media is somewhat chlorine tolerant.
It is recommended to add a carbon-based pre-filter, which we also supply in order to increase the longevity of the media.
Recognised
- The internal water filter media used in this system is Water Regulations Advisory Scheme (WRAS) approved, that demonstrates that it complies with the high standards set out by water regulations in the United Kingdom.
- Meets the National Science Foundation (NSF) 61 approval. This is the American standard for drinking water products which is world-renowned and internationally recognised.
- Tested by independent laboratories and researchers at Arizona State University our media achieved a 99% scale prevention effectiveness rating – the only non-salt technology to do so.

Pentek CHLORPLUS 10” Jumbo 1 Micron Carbon Block Filter
£58.99Product Description
Pentek ChlorPlus 10" x 4.5" Jumbo Carbon Block
This Pentek ChlorPlus 10" x 4.5" carbon block filter cartridge reduces chlorine and chloramine in residential and commercial drinking water. It has a nominal filtration rating of 1 micron at an efficiency of 85%.
The cartridge is made of bonded powdered activated carbon (PAC) media with a polyolefin core and shell and polyethylene outer netting. A Santoprene gasket provides a watertight seal.
The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 75% in up to 50,000 gallons at a flow rate of 1 gallon per minute (gpm) and reduce 3 ppm chloramines by at least 75% in up to 1,000 gallons at a flow rate of 1 gpm.
The filter has an initial pressure drop of 6 pounds per square inch (psi) at a recommended flow rate of 1 gpm and operates over a temperature range of 40°F - 180°F (4.4°C to 82°C)
This carbon block filter cartridge is used for treatment of residential and commercial drinking water.
Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes.
They are made of densely packed synthetic or natural fibres that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization.
For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings.
Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants.
The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced.
Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.

The nominal filtration rating is for a particle removal efficiency of 85%. Chlorine reduction capacity is the minimum total amount of water for which the free available chlorine (FAC) at a concentration of 2 ppm is reduced by at least 75%. Chloramine reduction capacity is the minimum total amount of water for which chloramines at a concentration of 3 ppm are reduced by 75%.
Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibres that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.

Finerfilters Salt Free Water Softener Alternative – Limescale Prevention – 10″ Jumbo Replacement Cartridge
£89.99Product Description
Finerfilters Salt-Free Water Softener Alternative - Limescale Prevention
10" x 4.5" Jumbo Replacement Cartridge
Hard water is naturally occurring, but the scale it leaves behind can have a very detrimental impact on the efficiency and life of your plumbing and appliances, such as heaters and boilers, as well as inhibiting the formation of soap suds, meaning you use more detergents and soap when washing clothes or bathing.
Although traditional salt-based water softener systems do remove the minerals which are attributed to limescale build-up, they also remove the minerals that are essential and healthy for us such as calcium & magnesium and leave behind large amounts of sodium which means your incoming water supply is now undrinkable.
This is usually remedied by creating two water feed lines, one salt softener treated line and one untreated line. This means more work for your plumber, increasing the cost of installing the system which you likely paid a lot of money for already.
Not only are they expensive to install they also require constant rejuvenation of salts and chemical cleaning in order to maintain their performance, which also comes at a cost both financially and environmentally.
Finerfilters’ Limescale Prevention Water Filter system uses an advanced filtration process known as Template Assisted Crystallization (TAC) which prevents the formation of limescale by converting those pesky scale causing hardness minerals into inert microscopic crystals via a catalytic reaction in the water being treated.
These crystals once created travel through the plumbing system and appliances in colloidal suspension - they do not stick to surfaces, which prevents the formation of limescale deposits so they’re no longer able to bond and stick to your pipes or appliances.
This system requires no electricity, doesn’t waste water by back-washing or regeneration, uses no salt or other chemicals, requires virtually no maintenance (the filter media should be changed after 1 year in foodservice applications and every 2 years in domestic applications), retains healthy minerals and adds nothing to the drinking or wastewater.
The media we use has been tested by independent laboratories and researchers and has a proven 99.6% rate of effectiveness (the only non-salt technology to do so) and can even help to reverse some of the scale build-ups which is already eating away at your existing systems such as heaters and boilers, allowing them to work more efficiently and use less energy meaning it can also help to reduce your electricity bills.
The benefits of using one of our Finerfilters Salt-Free water softener systems are numerous;
Multi-Purpose
- Feedwater needs less contact time than softener resin, so smaller systems can be used, making it perfect for use as a whole house system even if you have limited space and can also be used to protect systems such as instant hot water taps and coffee machines.
- Can be used in commercial applications by simply adding more media to the housing vessel.
- Our systems can also be used on water supplies obtained from wells or boreholes however heavy metals such as iron and manganese and excess sediment should be filtered out before the unit.
Environmentally Friendly
- Our systems not only prevent limescale formation but over time will gradually work to remove existing scale build-up whereas a traditional softener will only prevent new scale formation. This will in turn reduce energy consumption and improve the efficiency of your water heaters and boilers, essentially lowering energy bills.
The longer you use the system, the more apparent this becomes meaning your appliances stay functional for longer.
- Requires no salts, cleaning or use of chemicals or regeneration agents which can be harmful to the environment and increase the running cost.
- Doesn’t require backwashing of salts, so no additional connection to a drain line or wasteful usage of water.
- No brine discharge meaning our systems can be used in areas where conventional water softeners are banned or regulated.
Low-Maintenance
- Installation is a simple one-time process requiring only an inlet and outlet either at the Point-of-Entry (PoE) in a whole house system or Point-of-Use (PoU) to protect specific appliances such as coffee machines.
- Vastly improved filter lifespan and low maintenance; the media only needs to be replaced after 1 year in foodservice applications and every 2 years in domestic applications.
- The life expectancy of the housing system itself is much greater than a traditional softener system as it has no moving parts and is made from high-grade BPA free plastics.
Healthier
- Our systems do not remove any of the beneficial minerals that are carried by water, whereas a traditional water softener will.
Not only that, but our systems also do not add anything to your water supply whereas a traditional softener system adds harmful levels of sodium, making your water undrinkable. - Our salt-free water softeners do not remove chlorine which is added to municipal water supplies, but the media is somewhat chlorine tolerant.
It is recommended to add a carbon-based pre-filter, which we also supply in order to increase the longevity of the media.
Recognised
- The internal water filter media used in this system is Water Regulations Advisory Scheme (WRAS) approved, that demonstrates that it complies with the high standards set out by water regulations in the United Kingdom.
- Meets the National Science Foundation (NSF) 61 approval. This is the American standard for drinking water products which is world-renowned and internationally recognised.
- Tested by independent laboratories and researchers at Arizona State University our media achieved a 99% scale prevention effectiveness rating – the only non-salt technology to do so.

Finerfilters Salt Free Water Softener Alternative – Limescale Prevention – 10″ Jumbo Replacement Cartridge
£89.99Product Description
Finerfilters Salt-Free Water Softener Alternative - Limescale Prevention
10" x 4.5" Jumbo Replacement Cartridge
Hard water is naturally occurring, but the scale it leaves behind can have a very detrimental impact on the efficiency and life of your plumbing and appliances, such as heaters and boilers, as well as inhibiting the formation of soap suds, meaning you use more detergents and soap when washing clothes or bathing.
Although traditional salt-based water softener systems do remove the minerals which are attributed to limescale build-up, they also remove the minerals that are essential and healthy for us such as calcium & magnesium and leave behind large amounts of sodium which means your incoming water supply is now undrinkable.
This is usually remedied by creating two water feed lines, one salt softener treated line and one untreated line. This means more work for your plumber, increasing the cost of installing the system which you likely paid a lot of money for already.
Not only are they expensive to install they also require constant rejuvenation of salts and chemical cleaning in order to maintain their performance, which also comes at a cost both financially and environmentally.
Finerfilters’ Limescale Prevention Water Filter system uses an advanced filtration process known as Template Assisted Crystallization (TAC) which prevents the formation of limescale by converting those pesky scale causing hardness minerals into inert microscopic crystals via a catalytic reaction in the water being treated.
These crystals once created travel through the plumbing system and appliances in colloidal suspension - they do not stick to surfaces, which prevents the formation of limescale deposits so they’re no longer able to bond and stick to your pipes or appliances.
This system requires no electricity, doesn’t waste water by back-washing or regeneration, uses no salt or other chemicals, requires virtually no maintenance (the filter media should be changed after 1 year in foodservice applications and every 2 years in domestic applications), retains healthy minerals and adds nothing to the drinking or wastewater.
The media we use has been tested by independent laboratories and researchers and has a proven 99.6% rate of effectiveness (the only non-salt technology to do so) and can even help to reverse some of the scale build-ups which is already eating away at your existing systems such as heaters and boilers, allowing them to work more efficiently and use less energy meaning it can also help to reduce your electricity bills.
The benefits of using one of our Finerfilters Salt-Free water softener systems are numerous;
Multi-Purpose
- Feedwater needs less contact time than softener resin, so smaller systems can be used, making it perfect for use as a whole house system even if you have limited space and can also be used to protect systems such as instant hot water taps and coffee machines.
- Can be used in commercial applications by simply adding more media to the housing vessel.
- Our systems can also be used on water supplies obtained from wells or boreholes however heavy metals such as iron and manganese and excess sediment should be filtered out before the unit.
Environmentally Friendly
- Our systems not only prevent limescale formation but over time will gradually work to remove existing scale build-up whereas a traditional softener will only prevent new scale formation. This will in turn reduce energy consumption and improve the efficiency of your water heaters and boilers, essentially lowering energy bills.
The longer you use the system, the more apparent this becomes meaning your appliances stay functional for longer.
- Requires no salts, cleaning or use of chemicals or regeneration agents which can be harmful to the environment and increase the running cost.
- Doesn’t require backwashing of salts, so no additional connection to a drain line or wasteful usage of water.
- No brine discharge meaning our systems can be used in areas where conventional water softeners are banned or regulated.
Low-Maintenance
- Installation is a simple one-time process requiring only an inlet and outlet either at the Point-of-Entry (PoE) in a whole house system or Point-of-Use (PoU) to protect specific appliances such as coffee machines.
- Vastly improved filter lifespan and low maintenance; the media only needs to be replaced after 1 year in foodservice applications and every 2 years in domestic applications.
- The life expectancy of the housing system itself is much greater than a traditional softener system as it has no moving parts and is made from high-grade BPA free plastics.
Healthier
- Our systems do not remove any of the beneficial minerals that are carried by water, whereas a traditional water softener will.
Not only that, but our systems also do not add anything to your water supply whereas a traditional softener system adds harmful levels of sodium, making your water undrinkable. - Our salt-free water softeners do not remove chlorine which is added to municipal water supplies, but the media is somewhat chlorine tolerant.
It is recommended to add a carbon-based pre-filter, which we also supply in order to increase the longevity of the media.
Recognised
- The internal water filter media used in this system is Water Regulations Advisory Scheme (WRAS) approved, that demonstrates that it complies with the high standards set out by water regulations in the United Kingdom.
- Meets the National Science Foundation (NSF) 61 approval. This is the American standard for drinking water products which is world-renowned and internationally recognised.
- Tested by independent laboratories and researchers at Arizona State University our media achieved a 99% scale prevention effectiveness rating – the only non-salt technology to do so.

Pentek CHLORPLUS 10” Jumbo 1 Micron Carbon Block Filter
£58.99Product Description
Pentek ChlorPlus 10" x 4.5" Jumbo Carbon Block
This Pentek ChlorPlus 10" x 4.5" carbon block filter cartridge reduces chlorine and chloramine in residential and commercial drinking water. It has a nominal filtration rating of 1 micron at an efficiency of 85%.
The cartridge is made of bonded powdered activated carbon (PAC) media with a polyolefin core and shell and polyethylene outer netting. A Santoprene gasket provides a watertight seal.
The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 75% in up to 50,000 gallons at a flow rate of 1 gallon per minute (gpm) and reduce 3 ppm chloramines by at least 75% in up to 1,000 gallons at a flow rate of 1 gpm.
The filter has an initial pressure drop of 6 pounds per square inch (psi) at a recommended flow rate of 1 gpm and operates over a temperature range of 40°F - 180°F (4.4°C to 82°C)
This carbon block filter cartridge is used for treatment of residential and commercial drinking water.
Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes.
They are made of densely packed synthetic or natural fibres that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization.
For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings.
Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants.
The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced.
Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.
