Important: A whole-house filter is not automatically a water softener. Carbon, sediment and specialist media can reduce selected contaminants or manage scale, but true hardness removal generally requires a dedicated ion-exchange softener.
How we compare whole-house systems
AVERQUA compares treatment method, flow suitability, cartridge format, maintenance, installation requirements and current UK availability. We distinguish filtration from limescale management and from true water softening.
TreatmentSediment, carbon, specialist media or combined stages.
FlowPoint-of-entry systems must support household demand.
MaintenanceCartridge replacement, backwashing or media servicing.

Budget mains filter
Aquati Compact Chlorine Removal
£62.90*
A compact point-of-entry filter aimed at reducing chlorine in the incoming mains supply, using a 3/4-inch connection and a simple cartridge format.
Pros- Low purchase price
- Compact format
- No electricity
Consider- Not a softener
- Single-purpose treatment is narrower than multi-stage systems
- Professional installation may be preferable

Multi-stage mains treatment
BMB-1000 Hydra
£279.99*
A four-stage whole-house system combining 5-micron sediment filtration, activated carbon and polyphosphate scale management.
Pros- Sediment + carbon + scale management
- No electricity
- Compact whole-house format
Consider- Currently shown out of stock
- Polyphosphate manages scale rather than removing hardness minerals
- Annual filter costs matter
*Retailer price and availability checked 1 October 2026. Illustrative product graphic.
Premium twin housing
Osmio PRO-II-A
£352.00*
A twin-housing whole-house system using active ceramic followed by a carbon block, intended for mains treatment before point-of-use drinking-water filtration where required.
Pros- Compact twin-housing design
- Replaceable cartridge format
- Can be paired with separate hard-water treatment
Consider- Does not soften water by itself
- Installation space needed for cartridge changes
- Running cost depends on replacement schedule
*Manufacturer-listed price checked 1 October 2026. Illustrative product graphic.
Combined whole-home treatment
PuraLife POE 3000
£349.99*
A point-of-entry multi-stage filtration system sold with anti-scale or alkaline remineralisation options, intended to treat water throughout the property.
Pros- Whole-property treatment
- Multiple configuration options
- Current UK direct pricing
Consider- Confirm whether the chosen configuration removes hardness or only manages scale
- Professional plumbing recommended
- Replacement-media costs should be checked
*Direct UK price checked 1 October 2026. Illustrative product graphic.
Filtration + salt-free scale control
Aquatiere Pureau
From £540*
A whole-property system combining filtration with salt-free limescale control. The manufacturer states that it operates without softener salt, electricity or regeneration wastewater.
Pros- Combines filtration and scale management
- No salt handling
- No electricity stated
Consider- Salt-free conditioning is not the same as ion-exchange softening
- Higher upfront cost
- Choose system size carefully
*Manufacturer-listed starting price checked 1 October 2026. Illustrative product graphic.
Flexible modular platform
Ecosoft Aquapoint Standard
Check supplier
A configurable whole-house filtration platform designed for private houses and cottages, with multiple media and connection arrangements depending on the water problem being treated.
Pros- Flexible modular architecture
- Can be configured around specific water issues
- Suitable for more complex treatment chains
Consider- Not a simple off-the-shelf choice
- UK retail pricing is not clearly published
- System design should match actual water analysis

Whole-house filter or water softener?
Chlorine, taste and sediment
Whole-house carbon and sediment systems are designed around filtration. They can improve water characteristics without removing calcium and magnesium hardness.
Limescale management
Polyphosphate and salt-free conditioning can help manage scale formation, but that is different from removing hardness minerals from the water.
True softening
If your goal is measurable hardness reduction, compare dedicated ion-exchange water softeners separately and size them around household use and local hardness.
