What Is the ZeroB Suraksha Tap 2.0? Quick Specs at a Glance?
The Suraksha Tap 2.0 is ZeroB’s most accessible home water purifier. It attaches directly to your existing kitchen or bathroom tap, needs no electricity, and starts purifying water the moment you turn the dial to “purify” mode. For Indian households on municipal supply, it covers the last-mile contamination risk that even treated water can carry.

ZeroB is a flagship brand of Ion Exchange (India) Limited, which has over 40 years of experience in water treatment and was the first company in India to introduce NSF-certified resin technology for consumer water purification.
What Is Silver Resin Technology and How Does It Purify Water?
Silver Resin Technology is the core purification method in the Suraksha Tap 2.0. It combines ion exchange resin beads with silver infusion to neutralise bacteria, viruses, and cysts on contact as water flows through the cartridge.
What Is Exsil Nano Resin?
Exsil Nano Resin is ZeroB’s advanced (patent-pending) variation of silver-infused resin. The nano-scale silver particles embedded in the resin create a larger active surface area, making contact with a greater volume of water per second than conventional silver resin. When water passes through, silver ions are released at a controlled rate, disrupting bacterial cell membranes and inactivating viruses. The resin beads also act as a physical barrier, trapping sediment and fine particles that cause turbidity.
Unlike boiling, which kills germs but leaves dissolved solids and chemicals in the water, Exsil Nano Resin simultaneously targets biological contaminants, chlorine, bad odour, and taste issues. The result is water that is not just safe but also better tasting.
Why does NSF Certification matter?
NSF International is an independent, US-based body that certifies water treatment products against strict safety and performance standards. An NSF-certified resin has been independently tested and confirmed to reduce the contaminants its manufacturer claims. The resin in ZeroB’s Suraksha Tap 2.0 carries NSF certification, which means the core purification ingredient has been verified by a third party, not just claimed by the brand.
Ion Exchange India Limited, ZeroB’s parent company, was the first company in India to manufacture NSF-certified resin for consumer water products. This is a meaningful differentiator in a market crowded with products that carry no independent certification at all.
How to Install ZeroB Suraksha Tap 2.0 Without a Plumber?
Installing the Suraksha Tap 2.0 takes under two minutes and requires no tools, no drilling, and no changes to your plumbing.
- Unbox the Suraksha Tap 2.0. Inside, you will find the purifier unit and an adapter set to match your tap’s thread type.
- Remove the existing aerator from your tap by unscrewing it by hand (most Indian kitchen taps have a standard aerator thread).
- Select the correct adapter from the included set (male or female thread to match your faucet).
- Attach the adapter to the tap and then screw the Suraksha Tap 2.0 unit onto the adapter firmly by hand. No spanner or wrench is needed.
- Turn on the water. Rotate the dial on the Suraksha Tap 2.0 to “purified” mode. Water will flow through the cartridge and out purified.
- Run water for 30 seconds on first use to flush the cartridge before drinking.
The dual-mode dial lets you switch between purified mode for drinking and cooking, and normal flow mode for washing utensils or filling buckets. This way, your cartridge capacity is used only when you actually need purified water.
If you are a renter and move homes, simply unscrew the unit and take it with you. No damage to the tap, no permanent modifications to the kitchen.
Is ZeroB Suraksha Tap 2.0 Right for Your Home?
The Suraksha Tap 2.0 is purpose-built for one specific use case: municipal or corporation tap water with a TDS level at or below 500 ppm. This covers most urban and peri-urban Indian households.
Best For: Municipal Water Users with TDS Below 500 ppm
If your water comes from a corporation or municipality and your TDS is in the safe range, the main threats are biological: E. coli, coliforms, and seasonal bacterial spikes during the monsoon. The Suraksha Tap 2.0 handles all of these. It also removes chlorine and the taste issues that come with municipally treated water.
Who Should Consider an RO Instead?
If your water source is a borewell, overhead tanker, or a groundwater supply with TDS consistently above 500 ppm (common in Delhi, Rajasthan, Gujarat, and parts of UP), dissolved salts and heavy metals are the primary concern. In these cases, an RO purifier like ZeroB’s Magna Universal, which uses multi-stage RO+UV+UF, is the more suitable option.

The gap between a basic carbon tap filter and the Suraksha Tap 2.0 is significant. Most inexpensive tap filters improve taste and remove chlorine but do not address bacterial contamination at all. The Suraksha Tap 2.0’s NSF-certified nano resin provides genuine microbial protection, not just taste improvement.
6 Real-Life Situations Where Suraksha Tap 2.0 Makes the Most Sense
- Renters and paying guests. You cannot drill walls or install an RO system in a rented flat without the landlord’s permission. The Suraksha Tap 2.0 makes no permanent changes and packs into a bag when you leave.
- Families in frequent power-cut areas. RO and UV systems stop working the moment power goes out. The Suraksha Tap 2.0 runs entirely on water pressure. During a 4-hour power cut in the monsoon season, your family still gets purified water.
- Hostel residents and working professionals. A compact unit that attaches to a single tap is ideal for a shared kitchen or single-room kitchen in a city flat. No maintenance calls, no service contracts.
- Monsoon season protection. Municipal pipeline contamination risk peaks during heavy rainfall. The Suraksha Tap 2.0 provides a consistent point-of-use barrier even when water quality is most variable.
- Washing fruits and vegetables. Pesticide residues and surface bacteria on raw produce are a real concern. Running fruits and vegetables under the Suraksha Tap 2.0 in purified mode adds a simple extra layer of safety.
- Second taps and outdoor use. You can install one at the bathroom sink, balcony tap, or utility area, not just the kitchen. Its compact, waterproof-friendly design makes it flexible across any faucet in the home.
How Long Does the Filter Last and When to Replace It?
The Suraksha Tap 2.0 cartridge purifies up to 1,800 litres before it needs replacement. For a family of four using around 8-10 litres of purified water per day (drinking and cooking), that works out to roughly 6-7 months of regular use.
A few signs it is time to replace the cartridge:
- Water flow from the purifier slows noticeably.
- The taste of the output water changes or an odour returns.
- You notice the water looks less clear than usual.
- The built-in filter life indicator (on applicable models) signals the end of life.
Replacement cartridges are available directly on zerobonline.com, Amazon, and Flipkart. The cartridge swap takes about a minute: unscrew the old cartridge, screw in the new one, run water for 30 seconds to flush, and continue.
Running the unit past its capacity limit reduces purification effectiveness. Set a reminder at month 5 of use, so you replace it before performance drops.
If you want a reliable non-electric tap water purifier for your home this monsoon or whenever you move into a new flat, the ZeroB Suraksha Tap 2.0 is available at Rs. 1,899. It installs in two minutes and protects your family’s water from day one.
