Your Water Purifier Is Only As Safe As The Filter Inside It

The silent rise of spurious filters and what every Indian household must verify today -  Dr.Anil Kumar, Scientist, Eureka Forbes

Most Indian families trust their water purifier to deliver safe drinking water. The appliance is installed, serviced periodically, and assumed to be doing its job.

But many households don’t realise a serious risk: the purifier may still be working, but the filter inside it may have been replaced with a spurious or low-grade substitute. The machine looks the same, water flows normally, yet filtration performance may be compromised.

Counterfeit and generic filters have rapidly spread through India’s unorganised service market. During routine servicing, genuine OEM filters are sometimes swapped for cheaper alternatives that fit the unit but fail to remove harmful contaminants effectively. The consumer often remains unaware.

Clarity is not a measure of safety. Water free of visible impurities can still carry pesticides, heavy metals, and microbial contaminants at concentrations that pose serious health risks. A spurious filter creates the appearance of protection while allowing the most harmful substances to pass through unchecked and that false assurance is often more dangerous than no filter at all.

Multiple studies across Indian cities have found drinking water samples exceeding permissible limits for contaminants such as nitrates, arsenic, and chemical pollutants. Even treated municipal water can pick up impurities while travelling through ageing pipelines. In this environment, a purifier is only as reliable as its filter.

Genuine vs spurious filters

Genuine Aquaguard Nanopore Long-Life Filters are designed to remove pesticides, heavy metals, microplastics, viruses, and bacteria through precision-engineered pore structures.

Independent testing has shown that ordinary filters can lose performance rapidly, sometimes within months, allowing contaminants to pass through long before the consumer expects a replacement.

Signs your filter may be failing

· Metallic or musty taste in water

· Slower water flow

· Cloudy output

· Filter alerts ignored or reset without verified replacement

How to stay protected

· Ask to see the filter packaging before installation

· Check for Aquaguard branding and the unique QR code

· Scan the QR code to confirm authenticity

· Book service only through Eureka Forbes’ official app, website, or customer care

Spurious filters may cost less upfront, but they often stop working effectively much earlier, while households assume they are still protected. The difference in price is ultimately the cost of safety.

A water purifier protects your family only when it contains a verified, genuine filter installed by an authorised technician.

Insist on genuine.
Insist on authorised.
Insist on safety.
