RO (Reverse Osmosis), UV (Ultraviolet), and UF (Ultrafiltration) purifiers work differently to clean water. RO purifiers use a semi-permeable membrane called Reverse Osmosis Membrane removes dissolved contaminants such as dissolved solids, salinity, pesticides, herbicides as well as hazardous heavy metals as per BIS standards. It also removes harmful microbiological impurities such as bacteria, viruses and cysts from the feed water. It ensures safe and pure drinking water.

UV purifiers, on the other hand, use ultraviolet light to kill harmful bacteria and viruses but do not remove dissolved solids, which makes them best for soft municipal water.

UF purifiers filter out large particles and pathogens like algae, spores, cysts, bacteria, organic & inorganic polymeric molecules from water, and deliver excellent quality of clear water using a hollow fiber membrane.

In many homes, a combination of RO and UV or RO and UF is preferred for complete purification. If you’re buying a water purifier online, check your water’s TDS level first to determine which type suits your needs. While RO ensures safe, low-TDS water, UV and UF offer chemical-free protection against microbial contamination, making them a good choice for specific water sources.

The frequency of filter replacement depends on your water quality, daily usage, and the type of purifier you own. On average, most RO and UV water purifiers require filter replacement every 6 to 12 months. Pre-filters, which trap larger particles, may need changing sooner if your water source has high sediment levels. Ignoring filter changes can reduce the purifier’s efficiency, affect water taste, and even allow impurities to pass through.

If you buy a water purifier online, check if the model has a filter change indicator or digital alert system. Havells and other brands often include these smart features to remind you when maintenance is due. Regular service is also important to ensure all components, like the RO membrane or UV lamp, are functioning optimally.
