The Pearl Mini is a compact inline drinking water filter that reduces chlorine, improves taste and odour, and filters sediment, making it an ideal solution wherever installation space is limited.
With the filter contained entirely within the sealed cartridge, the Pearl Mini takes up very little room under a sink or behind an appliance. It's equally at home in kitchens, caravans, motorhomes, boats, refrigerators, water coolers and drinks machines where a larger filter simply won't fit.
Is tap water safe to drink? - Yes, but it doesn't mean you have to like it. Take your own water journey to answer this question for yourself.
You're looking for an effective drinking water filter but don't have room for a larger under sink system. The Pearl Mini's compact inline design fits neatly into tight spaces, making it ideal for kitchens, boats, caravans, motorhomes, water coolers, refrigerators, ice makers and drinks machines.
It's a great choice if you want better tasting drinking water, straightforward DIY installation and the flexibility to choose a cartridge that best suits your water filtration needs.
The Pearl Mini is designed to improve the taste and quality of mains drinking water, but it isn't suitable for every application. If you need to reduce bacteria or cysts, take a look at the Oyster TBC. For fluoride reduction see out dedicated fluoride filters, and if you want filtered water throughout your home, one of our whole house mains water filters.
Unlike traditional filter housings, the Pearl Mini uses a sealed inline cartridge, so when the filter reaches the end of its service life, the complete cartridge is simply replaced.

The performance of the Pearl Mini depends on the cartridge selected. Please refer to the specifications section for full details of each cartridge option.
Unlike a traditional under sink water filter, the Pearl Mini doesn't require a separate filter housing. The filter is contained entirely within a compact sealed cartridge with integrated ¼" push-fit connections, making installation quicker and ideal where space is limited.
Water passes directly through the selected cartridge, where the filter media performs the required treatment. Activated carbon cartridges help reduce chlorine, improve taste and odour, and trap fine sediment, while the dedicated sediment cartridge removes dirt, rust and suspended particles. If you choose the optional scale inhibitor cartridge, a small amount of food-grade polyphosphate is released to help reduce limescale forming in downstream appliances and pipework.
All cartridges are 10" long with 1/4" push-fit connections and fit the same inline filter. Choose the one that matches what you want to achieve:
| Cartridge | Type & media | Micron | Reduces | Capacity / life | Flow rate |
| Hydro H14PA | Carbon block | 1 | Taste, odour, chlorine | 8,000 litres | 4 lpm |
| Hydro H15PA | Carbon block with polyphosphate scale inhibitor | 1 | Taste, odour, chlorine + scale reduction | 6,000 litres | 4 lpm |
| Hydro H12PA | Spun polypropylene sediment insert | 5 | Dirt and sediment | Approx 12 months (depending on feed water quality and conditions) | 4 lpm |
| Hydro H14PAX (Hydro X, WRAS approved) | Long-life carbon block | 1 | Taste, odour, chlorine | Up to 9,500 litres or 6 months, whichever comes first | 3.8 lpm |
*Cartridge life is dependent on local water chemistry, flow rates, system design and application. Performance claims apply to a fully installed system connected to a pressurised water supply.
Everything you need to install the Pearl Mini is supplied in the box.
The Pearl Mini is installed inline on the cold water supply, making it suitable for dedicated drinking water taps as well as refrigerators, ice makers, water coolers, drinks machines, boats, caravans and motorhomes.
The integrated ¼" push-fit connections make installation quick and straightforward for anyone with basic DIY skills. Full fitting instructions are included with every filter, and you can also download the installation guide before fitting the system.
The Pearl Mini uses a sealed inline cartridge, so when it reaches the end of its service life, you simply replace the complete cartridge. There's no filter housing to open and no internal cartridge to change.
Replacement intervals vary depending on the cartridge selected, your water quality and the amount of water used. Please refer to the cartridge capacities above for guidance.
To make maintenance easier, we'll send you a reminder email every six months with a link to the correct replacement cartridge, so keeping your filter performing at its best couldn't be simpler.
The Pearl Mini is suitable for a wide range of applications where space is limited. As well as providing filtered drinking water at a dedicated kitchen tap, it's ideal for boats, caravans, motorhomes, refrigerators, ice makers, water coolers and drinks machines.
Choose the H14PA carbon block for everyday taste, odour and chlorine reduction; the H15PA if you also want to reduce scale build-up; the H12PA if you only need to filter out dirt and sediment; or the long-life, WRAS approved H14PAX if you'd prefer a higher-capacity carbon cartridge. All four fit the same inline filter.
The Pearl Mini is designed for installations where space is limited. The sealed inline cartridge measures approximately 10 inches long and 2 inches in diameter, making it much more compact than a traditional filter housing. Just make sure you have enough space for the tubing and to replace the cartridge when required.
Yes. The Pearl Mini is designed for DIY installation and features integrated ¼" push-fit connections for quick, straightforward fitting. Full installation instructions are included, and most customers can install the filter without needing a plumber.
Replacement intervals depend on the cartridge fitted, your water quality and how much water you use. For example, the standard carbon block cartridge has a typical capacity of around 8,000 litres, while the long-life H14PAX cartridge is rated to approximately 9,500 litres or up to 6 months. We'll send you a reminder email when it's time to check or replace your cartridge.
