Compatibility

The Acquapuro ACQ-IFC+ replacement filter cartridge is designed to replace an existing ACQ-IFC+ cartridge in a compatible filtration system.

It is suitable as a replacement cartridge for compatible:

• 3-in-1 and 4-in-1 boiling water tap systems, including the Aquila 4 in 1 boiling water tap
• Kitchen drinking water filter taps
• Fridges with an existing compatible inline filtration system
• Ice makers with an existing compatible inline filtration system

The ACQ-IFC+ combines a 1 micron carbon block with polyphosphate scale-control media, making it particularly useful in boiling water systems where filtration and protection against limescale are both required.

The manufacturer's technical information identifies kitchen filtration taps, ice-makers, fridges and 3 and 4-in-1 tank filtration among the intended applications.

Before ordering: Check that your existing cartridge is an ACQ-IFC+ cartridge and that you already have the appropriate filter head, connections and fittings. This product is supplied as a replacement cartridge rather than a complete installation kit.

What it reduces and what it doesn't

The ACQ-IFC+ replacement cartridge combines a 1 micron carbon block with polyphosphate scale-control media, providing drinking water filtration and helping protect compatible boiling-water systems and appliances from limescale.

Reduces / controls	What the filter does
Chlorine	Reduces chlorine to improve taste and odour
Fine particles & sediment	1 micron filtration reduces Class 1 particulates, rust, silt and other fine particles
Cysts	Mechanical filtration helps reduce cysts such as Cryptosporidium
Limescale	Polyphosphate helps inhibit scale formation and protects boilers and appliances
Other contaminants	Manufacturer states reduction of pesticides, insecticides, detergents, heavy metals, asbestos fibres, fine microplastics, and oxidised manganese, sulphate and iron

The manufacturer's chlorine testing provides particularly useful performance data. At a test flow rate of 2 litres per minute, chlorine reduction remained above 95% throughout testing to 7,200 litres, including 98.0% at 3,600 litres and 95.7% at 7,200 litres.

Scale-control testing was carried out using water at approximately 480mg/L hardness as CaCO3. Scale inhibition was 94.11% after 7,000 litres under the stated test conditions.

What it doesn't do

The ACQ-IFC+ is not a water softener. Polyphosphate helps control the formation of limescale but does not remove the calcium and magnesium minerals responsible for water hardness.

It is also not a reverse osmosis or specialist purification cartridge. The supplied technical information does not establish reduction of contaminants such as fluoride, nitrates or dissolved salts, so wwe wouldn't claim those reduction for this filter.

For those requiring a different level of treatment, see our water softeners for hardness removal or reverse osmosis filters for more comprehensive dissolved-contaminant reduction.

The manufacturer's documentation states that the cartridge uses a 1 micron carbon block and polyphosphate crystals, recommends a six month lifespan and describes the high-strength housing as capable of withstanding pressure above 120 psi / 8 bar.

How often to change and signs it needs changing

The ACQ-IFC+ replacement cartridge should be changed every six months or after approximately 6,000 litres of water, whichever comes first.

Regular replacement helps maintain drinking water quality and ensures the scale-control media continues to provide protection for compatible boiling water tanks and appliances.

The manufacturer's technical information recommends a six-month service life cartridge lifespan.

Signs that your cartridge may need changing include:

• A noticeable return of chlorine taste or smell
• Reduced flow from the filtered water outlet
• Increased signs of limescale around the boiling water system or appliance
• The cartridge has been installed for six months, even if water usage has been relatively low

Don't wait for a noticeable deterioration in taste before replacing the cartridge. The polyphosphate media also provides scale control, so an overdue cartridge may provide less protection even when the drinking water still appears normal.

If used with the Aquila 4-in-1 boiling water tap: replace the approved ACQ-IFC+ cartridge every six months and follow Acquapuro's descaling requirements to maintain the boiler warranty.

How to replace

The ACQ-IFC+ is a replacement cartridge for an existing compatible installation. Your existing filter head, pipework and reusable fittings remain in place and are not supplied with this replacement cartridge.

1. Turn off the water supply to the filter and open the filtered water tap to release any remaining pressure.
2. Disconnect the old cartridge from the existing fittings.
3. Remove any reusable fittings or elbows required for your installation from the old cartridge.
4. Fit the existing compatible fittings to the new ACQ-IFC+ cartridge.
5. Reconnect the cartridge to the existing pipework, ensuring all connections are fully secure.
6. Turn the water supply back on slowly and carefully check the connections for leaks.
7. Flush the new cartridge thoroughly before drinking the filtered water or using it with your appliance.

The existing filtration system may use 1/4 or 3/8ths inch push-fit pipework, which Acquapuro describes as allowing straightforward cartridge changes without specialist tools.

Important: The replacement cartridge does not include a new filter head, installation kit or connecting pipework.

FAQs

Is the ACQ-IFC+ suitable for boiling water taps?

Yes, when fitted as the replacement cartridge in a compatible existing filtration system. The ACQ-IFC+ is used with compatible 3-in-1 and 4-in-1 boiling water tap systems as well as drinking water filter taps, fridges and ice makers. The manufacturer's documentation specifically lists these applications.

Does the ACQ-IFC+ reduce limescale?

The cartridge contains polyphosphate crystals that help inhibit limescale formation. It does not soften the water or remove the calcium and magnesium responsible for hardness. Its role is to help control scale formation and protect compatible equipment.

How often should I replace the ACQ-IFC+ filter?

Replace it every 6 months or after approximately 6,000 litres, whichever comes first. Regular replacement helps maintain filtration performance and effective scale control.

Does the ACQ-IFC+ reduce chlorine?

Yes. The 1 micron carbon block reduces chlorine as well as associated tastes and odours. In the supplied performance testing at 2 litres per minute, chlorine reduction remained above 95% through testing to 7,200 litres.

Is this the complete ACQ-IFC+ filter kit?

No. This product is the replacement ACQ-IFC+ filter cartridge only. It is intended for customers who already have a compatible filter system installed. Filter head, connecting pipework and installation fittings are not included.
