How to Choose the Right Water Purifier in India
Drinking water that is clean and safe is essential for good health. In India, where tap water quality can be an issue, investing in a dependable water purifier is critical. With so many options on the market, selecting the best water purifier can be a difficult task. This article will walk you through the process of choosing the best water purifier for your needs, taking into account factors such as water TDS, purification technologies, and the various types of water purifiers available.
Main Types of Water Purifiers
1. RO Purifiers: Reverse Osmosis (RO) purifiers are highly effective in removing impurities, including harmful metals, bacteria, and viruses. They do, however, waste more water than they purify. In general, 1 litre of pure water is produced for every 3 litres of tap water. Furthermore, RO purifiers remove essential minerals from water such as calcium, magnesium, and sodium. Despite these disadvantages, RO purifiers are ideal for areas with high TDS levels and poor water quality.
2. UV Purifiers: Ultraviolet (UV) purifiers use ultraviolet light to disinfect water, eliminating bacteria, viruses, and other microorganisms. They do not remove dissolved impurities or essential minerals. Similar to RO purifiers, UV purifiers may wastewater in the purification process.
3. UF Purifiers: Ultrafiltration (UF) purifiers are capable of removing bacteria and germs, including dead organisms, from the water. They do not, however, remove dissolved solids. If you already have a RO purifier, you may not need a UF purifier because the filtration provided by the RO system is comparable or better.
Water Purifier Buying Guide:
Consider the following factors when buying a water purifier:
1. Check Your Water TDS
To begin, you must ascertain the Total Dissolved Solids (TDS) level in your water. The presence of inorganic salts, minerals, and other impurities in water is referred to as TDS. You can easily check the TDS level with a low-cost TDS metre, which costs around 200-300 rupees. If the TDS level in your water exceeds 2000 parts per million (PPM), it is considered highly contaminated, and a water softener rather than a water purifier is recommended.
Water softeners are best purchased locally because they must be customised to match your water pressure. TDS levels above 1500 PPM can also shorten the life of filters, especially membrane filters. If your water pressure is low, it can shorten the life of your filter, particularly the membrane. A UV or UF water purifier is appropriate if your TDS level is less than 200 PPM. A RO+UV water purifier is recommended for TDS levels greater than 200 PPM.
2. Purification Capacity
Determine your household’s daily water consumption and choose a purifier with the appropriate capacity to meet your needs.
3. Purification Technology
Choose the appropriate purification technology based on your water’s TDS level: RO, UV, or UF. If your water has a high TDS, a RO+UV purifier will provide comprehensive purification.
4. Storage Capacity
Look for a purifier with a large enough storage tank to provide enough drinking water for your family, especially during times of low water supply or emergencies.
5. Maintenance and Service:
Check the brand and model’s spare parts availability, maintenance requirements, and after-sales service support.
Seek out water purifiers that have been certified by reputable organisations like the Water Quality Association (WQA) or the Indian National Accreditation Board for Testing and Calibration Laboratories (NABL). These certifications ensure that the purifier meets industry performance and safety standards.
Set a budget based on your needs and compare various brands and models within that budget. Take into account the long-term costs of filter replacement and maintenance.

To summarise, selecting the right water purifier in India entails assessing the TDS level of your water, understanding the available purification technologies, and taking into account factors such as storage capacity, maintenance requirements, and budget. By considering these factors, you can make an informed decision and choose the best water purifier for your needs, ensuring you and your family have access to clean and safe drinking water.
