A countertop water filter system is a portable water filtration unit designed to sit on your kitchen counter. These systems typically come in two forms: tap-mounted and gravity-fed.
There are many reasons you might be considering a countertop water filter system. For renters, they’re a convenient, fuss free option that can move easily from one home to the next. Others may want a temporary solution during home renovations, or a portable system for events, travel, or outdoor gatherings.
The best choice for you will depend on your personal preferences and lifestyle needs. That’s why we’ve broken down the different types of countertop systems and key factors to consider, so that you can make an informed decision built around your needs.
Gravity water filter systems versus tap-mounted countertop systems
As mentioned, countertop water filter systems usually come in two forms: Gravity-fed or tap-mounted. Both options are ideal for renters or anyone looking for the convenience of filtered water in multiple locations. For example, a gravity filter could be used in the garden during a BBQ, in your office while working, or even on a bedside table if you're recovering with a newborn and need to stay hydrated during night feeds! Whilst the tap-mounted system could be taken on holidays with you to caravans or lodges, as long as the owner grants permission and the tap is compatible.
Gravity-fed water filter systems are typically larger and suitable for both individuals and families. They work by using gravity to pull water from an upper chamber through specialist filters into a lower chamber. These systems are incredibly popular for those who want to enjoy filter fresh water daily and can be used in various locations, such as your kitchen, office, garage, shed, or even the garden. Gravity filters also come in a range of sizes. If you're just starting out with water filtration, the 1-litre British Berkefeld system could be the perfect introduction and a great, plastic-free alternative to a classic filter jug. It offers the same benefits as the larger British Berkefeld systems but in a more compact form.
Tap-mounted systems, on the other hand, attach directly to the end of your kitchen tap and use water pressure to push water through the filter system and out through a small, separate, pillar style tap. The tap-mounted countertop water filter from Doulton comes with everything you need to set up in the box, allowing you to switch between filtered and unfiltered water with a small valve. This setup is perfect for those who enjoy the instant gratification of filtered water on tap but aren't ready to commit to plumbing in an under sink water filter system.
