RO or reverse osmosis is a process where water moves from higher solute concentration to lower solute concentration due to a pressure gradient. The filter has micro-pores that allow only water molecules and essential minerals to pass through. Although it blocks most larger ions, RO filters can also block some larger microbes. In other words, any dissolved particle larger than the water molecules will be blocked.
As so many products are already on the market, finding the best RO water purifier in India can be cumbersome. To help you with this, we have prepared a comprehensive list of the ten best purifiers with this filter that have become quite popular and consistently deliver incredible performance.

With all these water purifiers in the market, choosing the best RO water purifier hasn’t been easy. So, we decided to rank the available products based on the factors discussed below. After thoroughly scrutinising the list, we concluded with the ten products explained above that can be easily used at home and in the office.
- Features and specifications
The feature is the first and foremost factor we considered in choosing the best RO water purifier. For example, we considered the stages of purification, the maximum TDS level the product can handle, the presence of copper block, and many other features. In addition, we also considered the specifications, like the capacity of the water purifier tank, the filtration rate per hour, and the material with which it is made. We ensured to put only those water purifiers made from food-grade ABS plastic.
- Maintenance cost
We have also picked water purifiers with an affordable maintenance cost because these products are quite vulnerable to impurities in the inlet water.
- Service quality
The brands we have chosen for the RO water purifiers are known for their excellent after-sales service quality, installation quality, and product performance.
- Product quality and durability
We checked the quality and durability of every RO water purifier before adding them to the list. These products are known for their excellent purification performance and for maintaining the mineral concentration of the water. Also, they are highly durable and can last long, provided proper maintenance is done.
- Overall customer experience
Last but not least, we ensure to keep the products that can offer optimal user experience in terms of filtration speed, water quality, and the health benefits of purified water.
How does the RO water purifier function? Difference between RO, UV, and UF filters?
RO water purifier creates a pressure gradient to ensure water can pass from higher to lower solute concentration. Doing so removes heavy metals, pesticides, rust, and other impurities. The main difference between RO, UV, and UF filters is that the RO filter removes heavy metals and dissolved chemical impurities. The UV tank kills bacteria and other types of microbes. In contrast, the UF filter removes fine impurities from the water.
Which water purifier best suits different water types like Borewell, Hard Water, High TDS Water, Tank Water, and Iron water?
Since the water coming from different input sources has different levels of impurities, it will be better to check the TDS level of the water. Based on that, you can choose the perfect water purifier compatible with the TDS value you got from the test kit.
FAQs
1. Can we bathe from RO waste water?
No, you cannot bathe from RO waste water because it is high in impurities and can cause several skin infections.
2. What is RO in a water purifier?
RO in a water purifier means reverse osmosis. In this process, water moves from higher solid concentration to lower solid concentration under a pressure gradient, thereby eliminating heavy metals, dissolved chemical impurities, pesticides, and rust.
3. Best RO water purifier with copper tank
The best RO water purifier with a copper tank will be the HUL Pureit Water purifier.
Conclusion
Although RO water purifiers can easily remove maximum chemical impurities from the water, it would be better to choose a product with UV and UF filters. Apart from this, most products come with TDS remover to enhance the water taste and mineralizer for adding more minerals to the purified water. Check the total capacity of the water purifier to ensure it can match your daily water needs.
