These Under-the-Counter Water Purifiers Are Designed for Modern Kitchens With Limited Space (June 2026)

• We picked this because most modern kitchens in small apartments barely have counter space left after the mixer, jars, and induction, and this water purifier simply gets disappear under the sink while still giving you safe drinking water.  
• If your family takes water straight from the purifier for several cooking or consumption related activities, the smart display can certainly act like a quick health check so you always know the water is safe.  
• The storage helps during power cuts, as you will not have to wait with empty glasses in your hands when guests come home.  

Installation Guide

• Space needed: 16” W x 12” D x 18” H under sink that slides into most modular cabinets without cutting.
• Connections: Needs 1 tap water inlet + 1 power socket near the sink. No wall drilling.
• Install time: KENT technician performs free installation + TDS check in 45-60 mins.

Best for: Homes with an existing sink faucet hole, as the smart display faucet mounts directly and easily.

We picked this for homes where the water from the borewell leaves white marks on steel glasses, as it comes with 3000 ppm TDS handling, and cleans tough water so your food and water do not get that odd taste or smell.  

If your kitchen slab is always full during festivals and you still need water for many people, the 12L tank means can help yo have no waiting in line with empty glasses.  

For families who still believe in the old “copper vessel” habit but do not have time to maintain, keep, or refill one continuously, it can certainly add that copper goodness automatically in every glass in the machine only.

We picked this for homes where water pressure fluctuates from high to low and vice versa very frequently, for which the inbuilt pressure pump keeps the water running smoothly even with a tanker or low pressured municipal supply.  

If your family generally gets tensed about water tasting “flat” or “salty,” the Taste Adjuster can certainly let you fine-tune it so all your dishes and food taste just right.  

For modular kitchens with no space for bulky tanks, it can be kept hidden under the counter and keeps your slab free for mixer, tawa, and meal prep or any other important kitchen appliance.  

With 9-stage RO+UV+Active Copper, you may get both safety and that traditional copper touch, that too without washing a vessel daily.

Installation Guide

• Space needed: 13” W x 16” D x 18” H under sink space will be compact enough for most modular cabinets without cutting shelf space.  
• Connections: Needs 1 water inlet + 1 power socket, as the inbuilt pressure pump handles low water flow with no overhead tank needed.  
• Install time: Eureka Forbes technician does free installation + Taste Adjuster demo in 45-60 mins.
