Pentair Under-Sink Filters

Pure Drinking Water Straight from the Tap

Pentair under-sink filters, under the prestigious Everpure brand, offer the ultimate solution for pure drinking water straight from your kitchen tap. AQUA HUB GROUP supplies the complete range of Pentair drinking-water systems for residential and commercial applications. From simple single-stage filters to advanced multi-stage systems, Pentair offers the optimum solution for clean, great-tasting water in every situation.

The Everpure PBS-400 is the latest top model in the Pentair residential line. This advanced system uses Fibredyne technology for superior removal of chlorine, taste and odour compounds, and a wide range of contaminants. Micro-Pure membrane technology provides a filtration surface six times larger than traditional carbon filters, resulting in a longer service life and consistent water quality throughout the entire service life of the filter cartridge.

Pentair under-sink filters work on the basis of several filtration principles that work together for optimum water purification. Mechanical filtration removes solid particles down to sub-micron level, while activated carbon adsorbs organic contaminants, chlorine and by-products. Specialised media can additionally reduce heavy metals, PFAS compounds and other specific contaminants.

Pentair Everpure systems are the global standard for commercial drinking-water purification and are used by leading hospitality businesses, coffee chains and restaurants. The same technology is now available for residential use, so you can enjoy professional-quality water at home. The systems are certified to NSF/ANSI standards and comply with the strictest European and American regulations for drinking-water treatment.

Installing a Pentair under-sink filter is straightforward and can usually be done without professional help. The system is connected to the cold-water pipe under the sink and supplies purified water via a separate drinking-water tap or an existing three-way tap. The filter cartridge can easily be replaced without tools, which keeps maintenance to a minimum.

The benefits of filtered drinking water are numerous: improved taste and odour, removal of potentially harmful substances, no more need for bottled water, and long-term cost savings. A Pentair drinking-water system pays for itself within a reasonable time and contributes to a more sustainable lifestyle by reducing plastic waste.

AQUA HUB GROUP offers the complete range of Pentair under-sink filters with all the necessary installation materials, replacement cartridges and accessories. Our experts will gladly advise you on the optimum system for your water quality and needs.

Frequently asked questions about Pentair Under-Sink Filters

What is the advantage of an under-sink filter over a filter jug?
Under-sink filters provide continuously filtered water straight from the tap, with no waiting time or manual refilling. They have a higher filtration capacity, longer service intervals and better filtration quality than filter jugs. The fixed installation ensures consistent performance and convenience in daily use. In the long term, they are also more cost-efficient.
Do I need a separate tap for my drinking-water filter?
Usually, yes. A separate drinking-water tap is recommended to avoid wasting filtered water on washing up or other tasks. However, Pentair Everpure systems can also be connected to certain three-way mixer taps that have a separate channel for filtered water. AQUA HUB GROUP can advise on the best solution for your kitchen.
How long does a Pentair under-sink filter last?
The filter cartridge of a Pentair under-sink system lasts 6–12 months on average, depending on water consumption and water quality. The PBS-400 is designed for higher capacities and can last longer. The system itself (housing, connections) lasts many years with normal use and maintenance.
Which substances does the Pentair PBS-400 remove?
The PBS-400 with Fibredyne technology effectively removes: chlorine and chlorine by-products (>99%), taste and odour compounds, sediment and rust, lead (if present in pipes) and organic contaminants. The Micro-Pure membrane provides additional protection against microscopic particles. Specific reductions are NSF-certified and documented.
Can I install an under-sink filter myself?
Yes, Pentair under-sink systems are designed for easy DIY installation. Most systems are supplied with complete installation materials and clear instructions. Basic tools and plumbing knowledge are sufficient. If in doubt, or to preserve the warranty, professional installation may be considered.
How do I know when the filter cartridge needs replacing?
Replace the filter when: the recommended period or capacity has been reached (check the specifications), you notice a change in taste or odour, the flow rate drops noticeably, or six months have passed since the last replacement. Some systems have replacement indicators. Note the installation date to keep track.
Is Everpure the same brand as Pentair?
Yes, Everpure is a Pentair brand specialising in drinking-water filtration. For decades, Everpure has been the global standard for hospitality and commercial drinking-water systems, and this professional technology is now also available for residential use. AQUA HUB GROUP supplies the complete Pentair/Everpure range for home use.
Should I check my water pressure before installation?
Yes, check that your water pressure is within the range of the filter system (usually 1.4–8.6 bar). Pressure that is too low results in a slow flow rate; pressure that is too high can damage the system. If the pressure is too high, a pressure-reducing valve may be required. AQUA HUB GROUP can advise on the right configuration for your mains pressure.
Can an under-sink filter remove PFAS?
Standard carbon filters offer limited PFAS reduction. Effective PFAS removal requires specialised filters, such as the Pentair Freshpoint multi-stage systems, which are specifically certified for PFAS reduction. If PFAS is a concern in your region, AQUA HUB GROUP can advise on the right choice of filter.
