The Complete Guide to Best RO Water Purifiers in India 2022

An RO water purifier is a system that filters the impurities from water by using a process called reverse osmosis.

These days, buying a water purifier doesn’t have to be a chore. You can go online, select the brand of water purifier you want, and get the delivery in your door within just a few days. However, before you buy, I advise that you read my guide and learn about all the important factors before buying any water purifier.

Given all the factors, you need to determine your preferences. These preferences will undoubtedly vary depending on which region of the country you live in and what you do in your day-to-day life. Here are some questions you should ask yourself before purchasing a product:

Water Quality

If you want to buy a water purifier for inside your home, a common factor to consider is whether the water from your tap is hard (meaning there’s an overabundance of TDS or Total Dissolved Solids).

Dissolved solids are measured in parts per million (PPM). The World Health Organization (WHO) sets a limit between 50-120 PPM.

The inorganic salts in the water include calcium, magnesium, potassium, sodium, bicarbonates, and chlorides. To get rid of these compounds’ companies use the process of reverse osmosis or RO.

This uses a resilient, semi-permeable membrane with a size of about 0.0005 microns and is a good way to pre-process water. If you live in an area where the TDS level is high, then this system will help ensure you are getting the most purified water possible.

Water Pressure

Another factor you should consider when buying a water filter is pressure. A reverse osmosis system would be perfect for homes with high water pressure of 5 to 40 pounds per square inch.

If you have low water pressure, try attaching a booster pump to the RO system for your home. If you’re using a well and want to filter out more contaminants, we recommend that you consider activated carbon filters.

Contamination

The second thing to consider while you’re shopping for a new water purifier is contamination. Contamination means heavy metals such as lead, arsenic, magnesium, copper, and iron.

Heavy metals usually pose a significant problem when they accumulate in large amounts. The Industrial waste can often be the cause of this accumulation. This kind of pollution is harmful to your health, as heavy metals are toxic if ingested in large quantities.

While RO can get rid of inorganic compounds as well as heavy metals, it doesn’t do too well with microbes. In order to eliminate them, you will also need a special filter. A water purifier with a UV filter can not only disinfect the water but also restrict harmful microorganisms from multiplying in the water source.

The best way to avoid bacteria is to use a UV lamp on water. And you should also include a UV filter with an ultra-filter if the water supply is free from total dissolved solids.

Electricity

There are a number of water purifiers that require electricity in order to function. However, if you live in an area that faces frequent power cuts, it may not be the right choice for you. A UV filter also requires electricity to work since it uses the UV lamp for purification.

An RO system needs electric power to work. The only alternative would be to use an activated carbon filter or an ultra-filter. But they can only eliminate sediments from your water source, not the pollutants out there.

Daily Usage

One area you need to decide on is water consumption per day for your family. The first thing you’ll need to determine is whether or not you want a cleanse designed only for drinking purposes or for the entire house. Once you know the answer, it should be simple to figure out how much daily water consumption your family should take in.

If you drink a lot of water each day, then you will want a model with high power and extremely high output. Generally speaking, the output of a water purifier in an hour should be over the number of people in your home.

Portability

It’s not something you always think about when buying a water purifier. But it’s still very important for an 8-10 years investment.

If you are moving to a new place, don’t worry about having to buy a water purifier, because you will be able to use your existing one.

Make sure to take a look at the body of the water purifier, in addition to its portability and weight. There are also some aesthetics to consider, and a good-looking water purifier is sometimes more than just a nice bonus.

Budget

Once you know your water technology needs, it’s important to set a budget. A water purifier is not something you upgrade once or twice every year – it’s an investment that will require care, maintenance, and time.

So, we would recommend looking for a reliable brand. You will find yourself paying at least Rs 7,000 – Rs 8,000 on a water purifier. The cost will increase if you opt for a RO filter instead.

Maintenance cost

Considering the high effort and cost required to maintain water purifiers, you should be well-aware of your device’s needs and ensure changing the filter at least once every three months. This way, you won’t have to deal with potentially hazardous outages.

One tip to keep in mind is that you will need to replace your filter once per year. Generally, good purifiers come with a maintenance cost of around Rs 2,000 per year, but it can go as high as Rs 5,000. Some companies also offer annual maintenance contracts which may be worth looking into if they fit your budget.
