ZeroB is the flagship water purification brand of Ion Exchange India, one of the country's pioneering water treatment companies. The brand offers a comprehensive range spanning UV, RO, UF, and alkaline purification technologies, designed for households, small offices, and commercial settings. ZeroB's purifiers are built around intelligent monitoring systems that provide real-time information on filter status and water quality, distinguishing the brand from purely budget-focused competitors. This guide covers ZeroB's key features, maintenance requirements, and current pricing to help you decide whether the brand fits your household's water purification needs.

Once you pick a model, visit any of Bajaj Bajaj Finance’s 1.5 lakh partner stores in 4,000 cities in India and choose the air cooler that best suits your cooling needs. Customers can purchase their preferred model on Easy EMIs with zero down payment on select offers, making premium upgrades more affordable. With an Easy EMI Loan of up to Rs. 5 lakh and flexible repayment tenure, buyers can split the total cost into manageable monthly instalments. Simply check your loan eligibility online and bring home your desired air cooler without stretching your budget.

ZeroB purifiers combine up to four distinct purification methods depending on the specific model, each targeting a different category of water contaminant. The table below explains what each technology does and the type of contamination it addresses:

Choosing the right technology for your water source: if your water comes from treated municipal supply with low TDS, a UV or UF-based ZeroB model is generally sufficient. If your water source is borewell, tanker-supplied, or has a TDS reading above 500 ppm, an RO-based ZeroB model — such as the Wave Plus RO — is the appropriate choice. ZeroB's authorised technicians can advise on pre-treatment if your water condition requires it before installation, and the brand's service contracts specify a maximum supported TDS of 1,300 ppm beyond which additional pre-treatment is required.

ZeroB distinguishes itself through four consistent feature areas across its product range, summarised in the table below:

Regular maintenance is essential to keep any water purifier performing at its rated efficiency, and ZeroB systems are no exception. The five practices below cover the maintenance schedule recommended across most ZeroB models.

• Replace filters on schedule: Follow the manufacturer's guidelines for filter replacement intervals, which vary by model and usage volume. Filters and RO membranes are explicitly excluded from ZeroB's standard warranty, making timely replacement a direct cost consideration for ongoing ownership.
• Clean the exterior regularly: Wipe the purifier's exterior with a damp cloth to keep it clean and free of dust, which helps maintain both appearance and the unit's air vents where applicable.
• Check for leaks: Regularly inspect the purifier and its connections for any signs of leakage, and ensure all fittings remain secure over time.
• Schedule periodic professional servicing: Have the system serviced by ZeroB-authorised technicians as recommended, to ensure continued efficient operation. ZeroB's AMC (Annual Maintenance Contract) provides free servicing with chargeable parts, while the more comprehensive ACMC includes a one-time free replacement of filters and the RO membrane during the contract period.
• Monitor water quality directly: Keep an eye on the taste, odour, and clarity of your purified water. A noticeable change in any of these is often the earliest sign of a filter or membrane needing attention, even before the system's monitoring indicator flags an issue.

ZeroB offers a range of models across UV, RO, and alkaline categories, each suited to different household needs and water sources. The four models below represent ZeroB's range across capacity and technology type.

• ZeroB Kitchenmate UV (under-the-sink): A compact, under-the-sink UV purifier ideal for modular kitchens where counter space is limited. Best suited for households with low-TDS municipal water seeking microbial disinfection without RO's water wastage.
• ZeroB Wave Plus RO (7L, 6-stage): A wall-mounted RO purifier with 6-stage filtration specifically designed for high TDS and heavy metal removal, suited to borewell or tanker water sources and households of typical size requiring a steady 7-litre storage capacity.
• ZeroB UV Grande and UV Grande Plus (4L–6L): Compact UV-based purifiers ideal for small to medium-sized families, using a 6-stage UV purification process. The Grande Plus adds Active Silver Technology for enhanced protection. These primarily target bacteria and viruses and are most effective for households with municipal water that does not require dissolved solid removal.
• ZeroB Hydrolife (alkaline, under-sink): A premium under-sink alkaline water purifier combining RO purification with alkaline enrichment, carrying an extended 5-year warranty specifically on the electrolyzer cell — notably longer than ZeroB's standard 1-year product warranty.

How to choose: match the technology to your water source first (UV/UF for low-TDS municipal water; RO for borewell, tanker, or high-TDS water), then select the capacity and configuration (under-the-sink, wall-mounted, or countertop) that fits your kitchen space and household size.

The table below covers ZeroB models across the UV and RO range, with prices reflecting the brand's typical positioning relative to budget competitors.

Bajaj Finance offers two financing options for purchasing water purifiers. Both options are available at over 1.5 lakh partner stores across 4,000 cities in India, including Croma, Reliance Digital and Vijay Sales.

How to choose: Both options require you to be physically present at a partner store. The Insta EMI Card suits buyers who purchase across multiple categories over time. The Easy EMI Loan is better suited for a single water purifier purchase in one transaction. A minimum CIBIL score of 650 is required for both options.

The process is simple and typically takes 10 to 15 minutes once you are at the store.

1. Browse water purifier models on Bajaj Mall: Compare models by purification technology (RO, UV, UF), storage capacity, and price before visiting a store. Check your water source TDS level if known. Most municipal water in India ranges from 100–300 ppm, while borewell and tanker water can range from 500–2,000 ppm.
2. Find a partner store near you: Use the Bajaj Finance store locator to find the nearest Reliance Digital, Croma, Vijay Sales, or any of the 1.5 lakh partner outlets across 4,000 cities.
3. Check the purifier in person: Confirm the purification technology matches your water source (RO for borewell/tanker/high-TDS; UV or UV+UF acceptable for low-TDS municipal supply); verify the storage capacity suits your household size; ask about filter replacement frequency and AMC costs for the specific model.
4. Choose a suitable EMI option: Ask the store representative about the Bajaj Finance Insta EMI Card (pre-approved limit up to Rs. 3 lakh) or the Bajaj Finance Easy EMI Loan (up to Rs. 5 lakh). Both offer tenures of up to 60 months with zero down payment on select models.
5. Complete payment and take your water purifier home: The in-store process is quick, and most models are available for same-day pickup or scheduled installation.

You can also check your loan eligibility online in advance by entering your mobile number and OTP, helping you plan your purchase better before visiting the store.
