How to Hide a Water Purifier in Your Kitchen

Updated August 17th, 2021

Water purifiers, whilst useful (if not essential), are not exactly the most attractive piece of kit. But luckily, unlike whole-house water filtration systems, it is much easier to hide these small water purifier in your kitchen. Generally speaking, the most effective way to do this whilst causing the minimum amount of disruption to your kitchen design is to hide your water filter neatly under your sink. This is becoming an increasingly common setup for Reverse Osmosis (RO) water purifiers.

Under-the-sink RO Water Purifiers

Unlike the counter-top or wall-mounted versions, an under-sink water purifier saves you space whilst it provides you with perfectly clean drinking water. This type of system can be directly connected to a tap in your sink, so you will always have quick access to purified water, and your kitchen can remain as sleek and tidy as it ever was.

Pre-Installation Considerations

Power supply

You will need a plug socket nearby to connect your water filtration system, so prior to organising the installation you should check there is one available, and make the necessary arrangements if not.

Clean Area

For optimum longevity, the appliance should be kept in a place that is hygienic and free of dust and dirt. Make sure that the space under your sink is cleaned and there are no leaks.


The under-sink RO purifier has a more powerful filtration system and higher flow rate than its counterparts. As such, you’ll end up paying more for it outright. You should also consider the ongoing maintenance costs, including filter changes.

The video below will explain in detail how you can easily install you under-sink water filter:


High Flow Rate

Thanks to hydrostatic tanks that function to maintain optimum pressure, under-the-sink systems produce a steady and full flow of water which will fill bottles, pots, or other vestibules in a much faster time than your traditional water filter.

More Space on Counter-Tops

In a modern-day kitchen, it’s hard to find enough room for all the various appliances, gadgets, and gizmos. Especially when you’ve got a family—empty space fills up fast! Now you have one less thing to worry about, as your compact filter system is conveniently tucked away.

Better Tasting Food and Water

Perhaps not the first thing that springs to mind when you think about a hidden water filter—but, a very strong benefit nonetheless. The water that you use to wash your fruits and vegetables and cook with can seriously alter the final taste of your meals. Your taste buds will thank you!

Alternative Hiding Spots

If your under-the-sink area is looking a bit crowded, you might be tempted to hide your water filter in a kitchen cabinet instead. Upon first thought, it sounds like it should work but beware: the humidity and any leaks or water spillages can damage your cabinetry. In addition, the purifier must be easily accessible for routine maintenance, such as regular filter changes, and for any troubleshooting or repairs.


Nowadays, it’s very easy to hide your water filter in your kitchen. The preferred choice of most people is to store it under the sink, for practical reasons as well as aesthetics. This way will ensure that you get the most from your filter, and you can still enjoy uncluttered countertops in your kitchen.
