The standardised cartridge dimensions also provide flexibility when selecting compatible replacement cartridges. Integrated Pressure Gauges and Easy Maintenance The Aquafilter Big Blue filtration system incorporates two pressure gauges positioned at the inlet and outlet. These gauges allow users to monitor pressure before and after the filtration assembly. An increasing pressure difference across the system can indicate that filter cartridges are becoming loaded with contaminants and may require replacement. Integrated pressure relief valves allow trapped air and residual pressure to be released during servicing, helping simplify routine maintenance. The system is also supplied with a dedicated filter housing wrench for easier cartridge replacement. Suitable Applications The Aquafilter 10" Big Blue three-stage filtration system is suitable for a variety of cold-water filtration applications, including: Domestic whole-house water filtration. Residential Point of Entry (POE) installations. Chlorine reduction in mains water. Taste and odour improvement. Commercial buildings and premises. Offices and hospitality establishments.

Whole House Water Filtration Systems for Your Home

Enjoy improved water quality throughout your property with a whole house water filtration system from GroAqua. Also known as Point of Entry (POE) water filtration systems, these solutions are installed where the main water supply enters your property, treating water before it is distributed to your kitchen, bathrooms, showers and appliances.

 

Unlike under-sink or countertop water filters that treat water at a single outlet, whole house water filtration systems provide treatment across multiple water outlets throughout your home.

 

At GroAqua, we offer a selection of whole house water filtration solutions, including Aquafilter Big Blue 10-inch and 20-inch filter systems. Our collection includes options designed for sediment filtration, chlorine reduction, iron reduction, heavy metal reduction and water softening.

 

Whether you want to improve the taste and odour of your water, reduce unwanted particles or address specific water quality issues, explore our range of domestic Point of Entry filtration systems.

 

What Is a Point of Entry (POE) Water Filtration System?

A Point of Entry water filtration system is installed at the main incoming water supply to a property. This means water is treated before it reaches individual taps and appliances.

POE filtration systems are particularly useful for homeowners who want to improve water quality throughout their entire property rather than installing separate filters at individual outlets.

 

Depending on the filtration technology and cartridges selected, a whole house water filter can help reduce:

  • Sediment, sand, rust and suspended particles.
  • Chlorine and associated tastes and odours.
  • Iron and certain other dissolved metals.
  • Selected heavy metals.
  • Scale-forming minerals when an appropriate treatment system is installed.
  • Other unwanted substances, depending on the filtration media.

 

The correct system depends on your incoming water quality, household water consumption and the specific contaminants you want to address.

 

Benefits of Installing a Whole House Water Filter

A whole house water filtration system offers several advantages for residential properties.

 

1. Filtered Water Throughout Your Home

Because the system is installed at the main water inlet, treated water is distributed throughout your plumbing network. This provides filtration at multiple outlets, including kitchen taps, bathroom taps and showers.

 

2. Reduction of Sediment and Suspended Particles

Sediment filters help capture particles such as sand, rust, silt and other suspended solids. Removing these particles can help protect downstream plumbing components, appliances and additional filtration equipment.

 

3. Improved Water Taste and Odour

Activated carbon filtration is commonly used to reduce chlorine and certain organic compounds that can affect the taste and smell of water.

This can help improve the overall experience of using water for drinking, cooking and everyday household activities.

 

4. Targeted Iron Reduction

Properties experiencing elevated iron levels may benefit from specialist iron reduction filtration.

Excess iron can contribute to reddish-brown staining, discolouration and unpleasant metallic tastes. Selecting suitable treatment media can help address these problems.

 

5. Protection for Household Plumbing and Appliances

Appropriate filtration can help reduce sediment and other unwanted substances entering household plumbing systems and appliances.

The type of protection provided depends on the contaminants present and the filtration technology selected.

 

6. Treatment Designed Around Your Water Quality

Different properties experience different water quality challenges. A modular whole house filtration system allows you to select cartridges and treatment stages based on your particular requirements.

 

Types of Whole House Water Filtration Systems

Choosing the right whole house water filter starts with understanding the specific water quality issue you want to address.

GroAqua offers several types of Point of Entry filtration solutions.

 

Big Blue Whole House Water Filter Systems

Big Blue water filter systems are designed for applications requiring larger-capacity filtration cartridges and higher flow rates than many standard domestic filter housings.

They use large-diameter cartridges, typically available in 10-inch and 20-inch configurations.

Big Blue systems are commonly used for:

  • Whole house sediment filtration.
  • Chlorine and taste reduction.
  • Iron reduction.
  • Heavy metal reduction.
  • Multi-stage water filtration.
  • Specialist water treatment applications.

Their modular design allows different cartridge types to be installed depending on the incoming water quality and treatment requirements.

 

10-Inch Big Blue Water Filters

10-inch Big Blue filtration systems provide a compact whole house filtration option.

They are suitable for installations where space is limited and can accommodate a range of compatible 4.5-inch diameter filter cartridges.

Depending on the cartridge combination, a 10-inch system can be configured for sediment removal, carbon filtration and other specialist treatment applications.

 

20-Inch Big Blue Water Filters

20-inch Big Blue systems offer a larger filtration capacity and are often selected for properties requiring higher water consumption or longer cartridge service intervals.

The larger cartridge size can provide greater filtration media capacity compared with equivalent 10-inch cartridges.

These systems are available in single-stage, two-stage and multi-stage configurations, depending on the required treatment.

 

Multi-Stage Whole House Filtration Systems

Multi-stage filtration systems combine different cartridge technologies to address several water quality issues.

For example, a typical three-stage Big Blue system might include:

 

Stage 1 – Sediment Filtration

A sediment cartridge captures suspended particles such as sand, rust and silt.

 

Stage 2 – Activated Carbon Filtration

An activated carbon cartridge helps reduce chlorine, certain organic compounds and unwanted tastes and odours.

 

Stage 3 – Specialist Filtration

The final stage can be configured with specialist filtration media for specific requirements, such as iron reduction or other targeted contaminant reduction.

The actual filtration stages should always be selected according to the incoming water analysis and manufacturer specifications.

 

Choosing the Right Whole House Water Filter

There is no single filtration system suitable for every property. The best solution depends on your incoming water quality, household consumption and the contaminants you want to reduce.

Consider the following factors when selecting a whole house water filtration system.

 

Identify Your Water Source

The first step is understanding where your water comes from.

 

Mains Water Supplies

Mains water is generally treated before distribution, but homeowners may still want additional filtration to reduce chlorine, sediment and other unwanted substances.

 

Private Water Supplies

Properties using private water supplies, such as boreholes, wells and springs, may require more specialised treatment.

Depending on the source, additional treatment may be needed for iron, manganese, sediment, bacteria or other contaminants.

A water analysis is recommended before selecting a filtration system for a private supply.

 

Understand Your Water Quality

Water testing helps identify the substances that need to be reduced.

For example:

  • High chlorine levels may require activated carbon filtration.
  • Elevated iron may require specialist iron reduction media.
  • Suspended particles may require sediment filtration.
  • Certain heavy metals may require dedicated reduction cartridges.
  • Hard water may require a suitable water softener or scale treatment system.

Selecting filtration media based on actual water quality is more effective than choosing a system simply because it has multiple filtration stages.

 

Consider Water Flow Requirements

Whole house systems must provide sufficient water flow to meet household demand.

Consider how many outlets may be used simultaneously, including showers, taps, washing machines and other appliances.

Check the maximum flow rate and pressure specifications of each system before purchasing.

 

Choose the Correct Filter Housing Size

Big Blue systems are available in different sizes, with 10-inch and 20-inch cartridges being common options.

Larger housings generally offer greater cartridge capacity, although the actual service life depends on water quality, usage and filter specifications.

 

Consider Future Maintenance

Replacement cartridges need to be changed periodically to maintain filtration performance.

Before purchasing, consider cartridge availability, replacement costs and recommended maintenance intervals.

 

Whole House Water Filtration for Iron Reduction

Iron is a common water quality concern, particularly for properties using private water supplies.

 

Elevated iron concentrations can cause reddish-brown staining on bathroom fixtures, sinks, laundry and other surfaces. Iron can also affect the taste and appearance of drinking water.

 

Specialist whole house iron reduction systems use suitable filtration media to reduce iron concentrations before water enters the property's plumbing network.

 

The correct treatment depends on the form and concentration of iron present, as well as other water quality characteristics such as pH and manganese levels.

 

For more challenging water conditions, a dedicated iron removal system may be more suitable than a standard sediment or carbon filter.

 

Whole House Chlorine Reduction Filters

Chlorine is commonly used to disinfect public water supplies. Although it plays an important role in water treatment, some homeowners prefer to reduce chlorine levels to improve water taste and odour.

 

Activated carbon filtration is widely used for this purpose.

A whole house carbon filter is installed at the incoming water supply, allowing chlorine reduction across multiple household outlets.

 

This can improve the taste and smell of water used for drinking, cooking and bathing.

When choosing a carbon filtration system, consider the required flow rate, chlorine concentration and cartridge capacity.

 

Whole House Water Softening and Scale Reduction

Hard water contains elevated concentrations of dissolved calcium and magnesium.

These minerals can contribute to limescale formation in kettles, boilers, heating systems, showers and household appliances.

 

If hard water is a concern, a dedicated water softening system may be appropriate.

Water softeners typically use ion exchange technology to reduce calcium and magnesium concentrations.

 

It is important to distinguish between water softening and filtration. Standard sediment and carbon filters do not remove water hardness. Specialist softening equipment or suitable scale treatment technology is required.

Frequently Asked Questions About Whole House Water Filters

What is the difference between Point of Entry and Point of Use filtration?

Point of Entry (POE) filtration treats water as it enters a property, providing filtered water throughout the plumbing system.

Point of Use (POU) filtration treats water at a specific outlet, such as a kitchen tap or drinking water dispenser.

 

Do I need a whole house water filter?

A whole house water filter may be beneficial if you want to reduce specific contaminants throughout your property's water supply. The most suitable system depends on your water source, water quality and treatment requirements.

 

What does a whole house water filtration system remove?

The substances reduced depend on the filtration cartridges and media installed. Common treatment applications include sediment removal, chlorine reduction, iron reduction and selected heavy metal reduction.

No single system removes every contaminant, so it is important to choose a system based on water testing and manufacturer performance specifications.

 

What is a Big Blue water filter?

Big Blue is a large-capacity water filter housing format designed to accommodate wide-diameter filter cartridges.

These housings are commonly available in 10-inch and 20-inch lengths and can be configured with different filtration cartridges to address specific water quality requirements.

 

What is the difference between a 10-inch and 20-inch Big Blue filter?

The main difference is the cartridge length and available filtration media capacity.

A 20-inch Big Blue system generally offers greater cartridge capacity than a comparable 10-inch system. The best option depends on your flow requirements, installation space and water quality.

 

Can a whole house water filter remove iron?

Yes, provided the system uses suitable iron reduction filtration media. The correct treatment depends on the iron concentration, whether the iron is dissolved or particulate, and the overall water chemistry.

 

Will a whole house water filter remove limescale?

Standard sediment and carbon filters do not remove dissolved calcium and magnesium responsible for water hardness.

A dedicated water softener or appropriate scale treatment system is needed to address limescale.

 

How often should whole house water filter cartridges be replaced?

Replacement intervals depend on the cartridge type, incoming water quality, water consumption and manufacturer recommendations.

 

Check the pressure drop across the system, monitor water quality and follow the recommended cartridge replacement schedule.

 

Can I install a whole house water filtration system myself?

Some Big Blue filter systems are designed for straightforward plumbing installation, but installation requirements vary.

 

The system should be installed on the appropriate incoming water pipe, with suitable isolation valves, pressure ratings and plumbing connections. Professional installation is recommended where necessary.
