1. Features: Most important purchase criteria for non-electric water purifier

What should you look for when buying a new non-electric water purifier?

What should you look for when buying a new non-electric water purifier?

1.1 Types

Water purifiers are broadly classified into two types, i.e. electric and non-electric. Further, they are divided into with and without storage.

  • Non-electrical with storage water purifiers come with a storage tank to store water once it is purified. People who live in areas where water supply is not continuous and TDS is up to 350 PPM prefer this type of purifier.

  • Non-electrical without storage water purifiers are directly fixed to the water tap. They are candle-shaped filter consisting of a resin filter and has one month life. Same as with storage purifiers, this one also has UF and activated carbon filters and run without electricity. They are preferred by people who live in an area where water supply is continuous, and TDS is up to 350 PPM. Travel enthusiast often carries them due to their compact size.

  • Electric with storage water purifiers need electricity to run and always remain connected to the water supply. They use sediment filters, activated water filters with UV or RO technology to clean the water. They come with a storage tank for storing water. It is preferred in areas where the supply of electricity is continuous, or water has high TDS.

  • Electric without storage water purifiers works in the same way as an electric water purifier with storage tank. If you want to save space, you can choose this type.

  • Electric without storage water purifiers works in the same way as an electric water purifier with storage tank. If you want to save space, you can choose this type.

1.2 Technology

  • RO (Reverse Osmosis) Technology

RO is the most convenient, easy and effective method of removing impurities from water. In RO technology, water is pushed through the RO membrane using a high-pressure pump and forces which it gets from electricity. RO water is capable of removing even invisible impurities from water which makes it challenging, salty such as arsenic, sodium. It is the only technology which is capable of making desalinating seawater drinkable. If you receive water with up to 2000 PPM TDS, go for RO.

  • Gravity Based Technology

Gravity-base technology uses pressure filtration and is feasible for essential water purification. It consists of either sediment or both sediment and activated carbon filters. These filters are capable of removing large and un-dissolved impurities such as dirt, mud and sand and also some chemicals and microorganisms. This technology is an advanced version of tap/faucet filters which our grandmothers used to use.

  • UF (Ultra Filtration) Technology

Ultrafiltration uses a semi-permeable membrane to purify water, just like RO. The only difference is UF uses a membrane with much larger pores (appx. 0.01 microns) whereas RO uses a membrane with tiny pores (appx. 0.0001 microns).

As compared to RO, there are two benefits of using UF. First, it can work without electricity because the membrane has larger pores and water doesn’t need the force of gravity to pass; it can pass through naturally. Second, since no water is held back, there is zero wastage of water.

  • UV (Ultraviolet) Technology

In this technology, ultraviolet rays are used to purify the water. It is the quickest way to clean the water. When you buy a water purifier which uses this technology, there is no chemical alteration in water, i.e. it does not help to make soft water from hard water. It deactivates the microorganisms but doesn’t remove them or dissolved organics, inorganics or particles.

  • Activated Carbon 

Water purifiers using activated carbon technology are made up of charcoal granules, absorbs pesticides and herbicides. Same as gravity-based, this technology also doesn’t need electricity. They remove foul odour and chlorine-like chemicals from water, improving the taste of water.

  • EAT (Electro Adsorption Technology)

EAT purification technology consists of five advanced stages of purification. The technology is present in both electric and non-electric water purifiers. It is suitable for water less than 500 PPM TDS.

  • First Stage - The external prefilter removes impurities like sand, silica, silt, dirt and dust.

  • Second Stage - The mechanical filter removes dirt and suspended solids using sediment mesh.

  • Third Stage - Negative charge carrying impurities is removed at this stage by electro adhesion filter.

  • Fourth Stage - Ion exchange has activated carbon granules which removes heavy metals like lead and arsenic.

  • Fifth Stage - Lastly, the electro adsorption removes chemicals like chlorine, pesticides and endotoxins.

1.3 TDS

TDS is Total Dissolved Solids in water. TDS is more in groundwater and varies from one place to another. They contain harmful chemicals and continue consumption of it can cause intestinal irritation. Also, it is capable of changing the taste of the water. It is measured in terms of PPM (parts per million) or Milligrams per Litre (mg/L).

1.4 Water source

Water source determines the water quality. You need to know where do you get the water from. The water source determines if the water you receive is hard or soft. For example, if the water comes from underground water or deep dug bore wells, then it is hard water. Hard water contains high percentages of dissolved solids, harmful chemical and impurities, which makes the water unfit for human drinking. While, water coming from rivers, rainwater harvesting systems, lakes, and municipality managed storage is generally soft water. Soft water may not be as dangerous as hard water, but yet it needs purification to be deemed safe for human consumption over the long run.

1.5 Storage tank

Storage tank capacity refers to the ability of the tank in which purified water will be collected. At one time, that is the amount of water available to you for drinking. It mainly depends on two things. First, the size of your family as more members means a larger tank. Second, the purification rate, if the rate is fast, you can go for a smaller tank.

1.6 Total capacity

Do not consider just purified water storage capacity of the tank. Consider the total capacity of the tank as well. The non-electric water purifier has two compartments. The top compartment holds the raw water, that after purification goes down to the lower compartment as purified water for further consumption. If the capacity of the upper compartment is also huge, that means you might have to fill the water just once in 24 hours. The total ability of purifier depends on the number of members you have in your family.

1.7 Material

The material used in making the non-electric water purifier matters. Most of the gravity-based water purifiers are made up of food-grade plastic or ABS material. However, lately, stainless steel and copper water purifiers have been making their way in the market. If you store only cold water, you can choose any of the material. However, for storing hot water, stainless steel is the best. Similarly, our ancestors believed that it is healthy to drink water from a copper vessel. It helps in boosting immune system, strengthening the bones, increasing metabolism if you also think that, pick a water purifier with a copper tank.

1.8 Purification rate

Purification rate means how much clean water does the purifier provides in one hour. Most of the gravity-based non-electric water purifiers have 5 litres/hr to 120 litres/hr purification rate. Pick a water purifier that has at least 5 to 10 litres per hour purification rate.

1.9 Purification level

A gravity water purifier comes with more than one purification stage most of the time. Different purification technique is used at each stage. The more number of steps, the more purified water you have. Some of the standard purification stages are as follows:

  • Pre-filter or Sediment pre-filter: Pre-sediment filter removes large particles like dust, mud, and sand. At the same time, it improves the life of the UF membrane resulting in a lower cost of maintenance. If your purifier does not have this, you can add it separately.

  • Activated Carbon Filter – It removes chlorine, invisible impurities, harmful pesticides, and chemical contaminants from water. It is capable of eliminating foul odour, colours of water, and also, absorbs taste-causing organic compounds.

  • UF membranes: The UF membrane works just like RO membrane, but it does not remove the dissolved impurities. Therefore, UF membrane helps you get rid of salts, pesticides and heavy metals like lead & mercury, microbial contaminants like a virus, bacteria, protozoa, and cysts as long as they are not dissolved.

  • Carbon post-filter: Also know as a polisher, it re-filters the already purified water by enhancing the taste and removing any foul smell from water.

1.10 Filter life

Filter life refers to the amount of water a purifier can filter in its lifetime, and it varies from filter to filter. Some call for replacement every three months, whereas some work for even a year, depending on usage.

Replacement is required due to clogging of sediment filters and meshes. We suggest, get a water purifier that can filter at least 1500 litres of water.

1.11 Auto shut-off

It is an essential and beneficial feature of the non-electric water purifiers. This feature notifies you when the filter has stopped working, and the leakage of water starts from the purifier. In this manner, it reminds you that it is the filter time.

1.12 Microporous Candles

Microporous Candles are also knowns as ceramic candles, and you will find them in stainless steel water purifiers. Usually, three candles are used at a time to clean water. Together they are capable of filtering 1 to 2 litres of water per hour.

If you are using these for the first time, place them in hot water for at least 6 to 8 hours to open their pores. For the first week, the water flow may be slow, but it will gradually increase.

1.14 Filter maintenance

Not just the water purifier, but the filter placed within it also needs cleaning and maintenance from time to time. However, their cleaning is not possible at home. In fact, they need to be replaced when their time is over. The lifespan of a filter could be between three months to a year or more. However, experts suggest that filters before completing their lifespan.

2. Use Cases: The best non-electric water purifier for you

Which type of non-electric water purifier is best for your use cases?

Which type of non-electric water purifier is best for your use cases?

2.1 I receive hard water at my home. Is gravity-based water purifier right for me?

No. Hard water usually has a high TDS level besides toxins. A non-electric water purifier is not suitable to purify that level of impurities present in the water.

No. Hard water usually has a high TDS level besides toxins. A non-electric water purifier is not suitable to purify that level of impurities present in the water.

2.2 I get 350PPM water at my place. Is a UF filter technology sufficient to clean the water with that TDS level?

UF filters work best when used in combination with another water purification system because they don’t kill any microorganisms or biological impurities in contaminated water. They are capable of removing only suspended solids from water.

If the water in your area has TDS less than 500 PPM, mud but no biological impurities, only then you should get UF filter water purifier.
