Explore Under Sink Water Filter Systems in India

Under-sink water filters offer a space-saving way to get filtered drinking water directly from your kitchen sink.

• A clutter-free kitchen: The system sits below the sink, keeping your countertop clear.
• Filtration options: Choose from RO, UV, UF or multi-stage systems based on your water quality.
• Different household needs: Water source, storage capacity and pressure requirements vary by model.
• Installation matters: Check cabinet space, plumbing and whether the system includes a separate dispensing tap.
• Ongoing costs: Factor in filter replacements, maintenance and local service support before buying.

You can also buy a new water filter on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales. 

Under sink water filter systems are installed below the kitchen sink and provide filtered water through a separate tap. They can help save counter space while keeping the filtration unit out of sight. In India, these systems are available with different filtration methods, including RO, UV, UF and multi-stage filters.

Before choosing one, compare your water source, filtration needs, storage capacity, installation space, filter replacement cost and maintenance requirements.

You can buy a new kitchen appliance through Easy EMIs when your preferred model is eligible and available at a partner store, making it simple to upgrade without paying the full amount upfront. Here is what the process looks like.

• Visit more than 1.5 lakh partner stores across 4,000+ cities, including Jaipur, Lucknow, Kochi, and Bhopal
• Choose your preferred model and use the Bajaj Finance Insta EMI Card or Easy EMI Loan
• Convert the purchase cost into Easy EMIs that suit your monthly budget

➜ Pro tip: Zero down payment is available on select models, so ask the store executive if your chosen kitchen appliance qualifies before you check out.

Under-sink water filter systems come in several types, each using different filtration methods to improve water quality for specific household needs effectively.

• Activated carbon filters: Activated carbon filters reduce chlorine, odours and some organic compounds while retaining useful minerals naturally.
• Reverse osmosis systems: Reverse osmosis systems remove many dissolved salts, heavy metals and contaminants using a semipermeable membrane.
• Ultrafiltration systems: Ultrafiltration systems use fine membranes to remove suspended particles, bacteria and some microorganisms from water.
• Multi-stage filters: Multi-stage filters combine sediment, carbon and membrane stages to address several water-quality concerns in homes.
• Sediment filters: Sediment filters trap sand, rust and visible particles, usually serving as a pre-filtration stage first.
• Alkaline filters: Alkaline filters may raise pH and add minerals after filtration, depending on cartridge design used.

Choose an under-sink filter based on your water source, tested contaminants, maintenance needs, available space and the level of filtration required overall.

Installing an under-sink water filter involves preparing the cabinet, connecting the water supply and checking the system before use.

First, prepare: Shut off the cold-water supply and clear enough cabinet space for installation and future filter changes.

Next, connect: Install the dedicated faucet if supplied, attach the inlet adapter, connect the tubing and secure the filter housing according to the manufacturer’s instructions.

Before drinking: Restore the water supply slowly, inspect every connection for leaks and flush the system for the recommended period.

Pro tip: If plumbing modifications are needed, use a qualified installer to prevent leaks and incorrect connections.

After installing an under-sink water filter, test water flow, taste, leaks and connections to confirm the system is working properly overall safely.

• Check for leaks: Inspect all fittings, tubes and connections for dripping, moisture or loose joints.
• Flush the filter: Run water for the manufacturer-recommended period to remove air and carbon particles.
• Check water flow: Make sure filtered water flows steadily without unusual pressure drops or interruptions.
• Inspect water clarity: Fill a clean glass and check for cloudiness, sediment or visible particles.
• Taste and smell: Check whether filtered water has any unusual taste, odour or metallic notes.
• Test faucet operation: Turn the filter faucet on and off to confirm flow and sealing.
• Monitor for hours: Recheck fittings after several hours because slow leaks may not appear immediately.

If the filter passes these checks without leaks, unusual taste or poor flow, continue using it and follow the recommended maintenance schedule.

Installing an under-sink water filter is easier when you have the right tools ready.

→ Pro tip: Check the manufacturer’s manual before starting. Some installations require additional fittings or tools, and not every connection needs plumber’s tape.

Yes, you can install an under-sink water filter without a plumber if the kit is designed for DIY fitting and your plumbing setup is straightforward. Most systems connect to the cold-water line and include the required tubing, fittings and faucet parts. You will need basic tools and must follow the manufacturer’s instructions carefully.

Turn off the water supply before starting and check every connection for leaks afterwards. If drilling, modifying pipes or dealing with unusual fittings is required, hiring a plumber is safer and can help prevent water damage later.
