RO Water Purifier in Nepal: Is It Worth Buying

Clean and safe drinking water is becoming an issue in most regions of Nepal. In cities where the sources of water can be polluted or uneven in quality.

As there is a growing consciousness of health and hygiene. The number of households which are resorting to water purification systems has increased in order to have safe drinking water. RO(reverse osmosis) water purifiers have become very popular among the available alternatives. Because of their capacity to eliminate impurities, poisonous chemicals and dissolved solids.

In this guide, we will discuss the operation of RO water purifiers, their advantages and disadvantages. Whether they are the correct decision for you or not!!

What is an RO Water Purifier?

An RO water cleaner is a filter used to filter out impurities from water using a membrane, which acts as a filter. It is attached to filter out salts, metals, germs, infections, and other hazardous impurities present in water, making it drinkable.

An RO purifier operates at a microscopic level unlike the simple water filters that only eliminate the visible particles. It forces the water to go through a special membrane that only permits the passage of clean water molecules and not the contaminants like lead, arsenic, chlorine and excess minerals.

How RO Purification Works?

The RO (Reverse Osmosis) purification technique involves a multi-step filtering process in which all visible and tiny pollutants are eliminated from the water. This process is carried out in order to make sure that the water you consume is tidy, safe, and without all kinds of contamination.

Step 1: Pre-Filtration

The first filter is made of water, sediment and carbon. These filters eliminate dust, dirt, rust and chlorine and ensure that the RO membrane is not damaged and the overall performance is enhanced.

Step 2: RO Membrane Filtration

This is what the system is all about. Water passes through a semi-permeable membrane which prevents the dissolved salts, heavy metals, bacteria and other undesirable elements. Only pure water molecules are permitted to pass through.

Step 3: Post-Filtration

The water can be further filtered with other filters like carbon filters or UV purification to eliminate any other impurities left and also enhance taste after RO filtration.

Step 4: Storage

The clean water is kept in a tank, which is used whenever it is required.

The multi layered process of RO purifiers is very effective, particularly in areas where water quality is not consistent. It makes water, even the mixed or unreliable water, safe enough to be consumed on a daily basis.

Common Water Quality Issues in Nepal

The quality of water in Nepal is highly variable in terms of the source, place, and time of year. In most places, particularly in urban locations such as Kathmandu, families use a combination of municipal supply, tanker water and underground water.  This exposes the chances of contamination and poor quality water.

High TDS (Total Dissolved Solids), which is comprised of extra minerals, salts, and metals, is one of the most common ones. Although some of them are harmless, when taken in huge quantities, they might disturb taste, as well as health, in the long run.

Microbial contamination is also another significant issue. Water may be contaminated by bacteria, viruses, and parasites that may be caused by improper sanitation, pipeline leakages, or storage tanks. This may cause waterborne diseases in case not treated.

Water can also be contaminated with chlorine, sediments and bad smells particularly when obtained through tankers or when kept in long storage. The above aspects render untreated water inappropriate to be consumed directly.

Benefits of Using an RO Water Purifier

There are a number of benefits associated with RO water purifiers when the quality of water is questionable. They are increasingly becoming a favorite in Nepal among households and offices that seek safe and reliable drinking water.

1. Removes Harmful Contaminants

An RO purifier can be used to remove the dissolved salts, heavy metals such as lead and arsenic, and other toxic chemicals. In this way, the water is made very safe as compared to the raw sources.

2. Protects Against Bacteria and Viruses

A multi-step water filtration system, in most instances including UV/Ultra-Filtration, is applied to eliminate or inactivate microorganisms that may potentially cause water-borne diseases using the RO system.

3. Improves Taste and Odor

The RO water filter eliminates chlorine, sediments, taste and odor-altering impurities, and leaves the water purer and more palatable to you.

4. Suitable for High TDS Water

RO is among the best options to reduce the TDS in your water supply in case it is high (which is typical of tanker or underground water).

5. Convenient and Reliable

RO purifiers once installed will give a continuous supply of clean water at home eliminating the need to use bottled water or boiling.

6. Long-Term Cost Saving

It might be more expensive in the short run, but an RO purifier could save money in the long run as it would not be necessary to purchase bottled water on a regular basis.

Drawbacks of RO Water Purifiers

Although RO water purifiers have numerous advantages, they also have some disadvantages that you should take into consideration before buying them.

1. Water Wastage

Among the largest drawbacks of the RO systems is that they use a certain volume of water in the purification process. A few liters of purified water can be discarded per liter of purified water and this can be problematic in regions where there is a shortage of water.

2. Removes Essential Minerals

The purification of RO not only eliminates toxic substances but also certain minerals that are vital such as calcium and magnesium. This may render the water unhealthy unless the system incorporates a mineral enhancer.

3. Higher Initial Cost

Water purifiers that use RO are usually of higher cost than the simple filters such as the UV or UF filters. Initial investment can be a determining factor to a large number of households.

4. Regular Maintenance Required

RO systems require maintenance such as the replacement of filters and membranes. This contributes to the cost in the long term and it has to be taken care of to sustain performance.

5. Requires Electricity

The majority of RO purifiers require power. This may be constrained when there is a power outage unless the system has a backup.

6. Not Always Necessary

When you have low TDS in water already and the water is quite clean, then you may not need an RO purifier. In those cases, less complex filtration techniques can be more appropriate.

RO vs UV vs UF

Selecting a water purifier in Nepal, should know the difference between RO, UV, and UF systems. The technology is specific to certain conditions of water, and the most suitable one is determined by the water source and quality.

RO (Reverse Osmosis)

RO purifiers are suitable in water that has high TDS like tanker or underground water. They eliminate dissolved salts, heavy metals, and toxic chemicals, which makes them the best in regions where the quality of water in questionable.

UV (Ultraviolet)

UV purifiers take advantage of the ultraviolet light to kill bacteria and viruses. They can be used in water that has already been cleared but can have microorganisms. Dissolved salts or chemicals are not removed by UV systems.

UF (Ultrafiltration)

UF filters work on the basis of a membrane to eliminate bacteria and suspended particles. They do not need electricity and suit well in the region where the water has low TDS, yet is ineffective in removing dissolved impurities.

How to Choose the Right RO Water Purifier

The selection of an appropriate RO water purifier will be based on the quality of water, usage and cost. There are numerous choices in Nepal to choose a system that suits your real requirements.

1. Check Your Water Source and TDS Level

Begin by knowing your source of water, whether it is a municipal source, tanker or ground. In case the TDS concentration is high, an RO purifier is a good option. In case of low TDS water, a complete RO system may not be necessary.

2. Look for Multi-Stage Purification

Contemporary purifiers tend to be a combination of RO+UV+UF. This gives it greater protection by eliminating dissolved impurities, bacteria and viruses.

3. Consider Storage Capacity

Select a purifier that will fit your home requirements in terms of storage tank size. The bigger families are supposed to have a higher capacity to guarantee that there is a constant water supply.

4. Check for Mineral Retention Features

RO eliminates vital minerals, so consider models that have a TDS controller or mineralizer to have healthy drinking water.

5. Evaluate Maintenance and Service

It is essential to service the performance regularly. Select a brand or a supplier that is easy to maintain and has good after sales services.

6. Compare Budget and Long-Term Cost

Not only the initial price but also the cost of replacement of the filter and servicing in the long run.

7. Choose a Trusted Brand

When selecting a purifier, it’s important to choose a reliable brand with proven performance and service support. Brands like Faber and Neo offer a range of RO water purifiers suitable for Nepal’s varying water conditions, along with dependable after-sales service.

Maintenance and Filter Replacement

In order to maintain your RO water purifier in a good working state, it is important to maintain it. Over time, filters and membranes become blocked with impurities and this may decrease performance and water quality.

A majority of RO systems need:

• Pre-filters (sediment/carbon) change every 1-3 months, depending on water quality.
• Replacement of the RO membrane after every 1-2 years.
• At least once a year general servicing.

Is RO Water Safe and Healthy?

Yes, RO water is usually safe to drink since it eliminates toxic contaminants, heavy metals and microbes. This renders it a good choice in regions where the quality of water is doubtful.

But, as RO also takes away some important minerals, it is preferable to have a purifier that has a mineralizer or TDS controller. This aids in sustaining an even proportion of minerals and this makes the water safe and healthy to consume on a daily basis.

Who Should Buy an RO Water Purifier?

Although it is not necessary for all to have an RO water purifier, it is highly suggested in some situations. You need to think about purchasing an RO purifier in case:

• High levels of TDS in your water
• You depend on tanker or underground water
• Your water has a bad taste, smell, or visible impurities
