As the name itself suggests, the Non-Electric Water Purifiers doesn’t require electricity to operate, and these water purifiers work only when the TDS levels in the water are low.

If you get water from Public water supply or Municipality water, you can simply install a Non-Electric water purifier and get the Safe Drinking water.

In Case, you get water from a source that contains high TDS levels, and you have to buy an RO water purifier. I have already compiled the list of Best RO + UV + TDS water purifiers.

The Best thing about the Non-Electric Water Purifiers is, the maintenance is very easy, and they can be easily installed by yourself, and there won’t be any water wastage.

List Of Best Non-Electric Water Purifiers

I have the compiled the list based on the real user reviews, the performance of the water purifier, technical specifications, robustness, and cost.

1. Whirlpool Destroyer 6-Litre Water Purifier 

Whirlpool destroyer

Whirlpool is an American Multinational manufacturer of Home Appliances, and now they recently designed a Non-Electric Water Purifier specially designed for Indian Home, and they named it Whirlpool Destroyer.

The Capacity of the Non-Electric Whirlpool water purifier is 6 liters, and the purifiers come with a Ground-Breaking EAT filter technology, and life of the EAT filter is 2200 liters.

The Easy to operate water purifier can be installed and maintained without any hassles. You don’t have to contact the service provider for installing the water purifier at your home.

Whirlpool Claims that their non-electric Destroyer can work with water levels up to 500ppm.

Some of the cheap RO Water purifiers also work with water that contains levels of dissolved salts below 500 ppm only.

The Electro Adsorption technology has the capability to retain natural minerals in the water which is not possible even in some of the Reverse Osmosis water purifiers.

EAT (Electro Adsorption Technology) offers immense power and advantages of 4 filters in one physical filter and provides 5-stage water purification.

In the first stage, the external pre-filter removes the Sand, Silica, Slit, Dirt, and Dust from the input water. The Mechanical filter is the next level removes the suspended solids from water. In the later stages, the EAT filter removes the Harmful Bacteria, Virus, and Cysts.

Ion exchanges take place to the next level, and the specially activated carbon granules remove heavy metals like lead and arsenic. Dangerous chemicals like Chlorine, Pesticides will be washed away from the water in the last stage.

The Best thing about the whirlpool EAT technology is, there will be no water wastage. All the RO water purifiers waste one liter of water when you input 2 liters for purification.

On the top of all these features, the Whirlpool destroyer works without electricity.

If the TDS level of water at your Home is less than 500 PPM, then the whirlpool destroyer is the right choice for you.Button

3. Kent Gold Star 22-Litre Water Purifier

Kent Gold star gravity

The water purifier is recommended only when your water source doesn’t have heavy metals like Arsenic and lead.

I don’t suggest anyone buy a Gravity-based water purifier if you want to use the filter for a longer period. The Gravity based water purifiers are not as effective as Ro or UV water purifiers.

Water purifiers are a one-time investment, and you have to make sure you are investing your hard earned money a product that is worth it.

If you are on a tight Budget, you can buy the Kent-Gold Non-electric Gravity based UF water purifier.

All The Gravity based water purifier are suitable with low TDS water only. Unlike the Whirlpool Destroyer, the Kent Gold doesn’t work with water that contains TDS levels up to 500ppm.

ABS Plastic is the material that is used to construct the water purifier. The Water purifier can be placed on the countertop, or you can mount to the kitchen wall.

The weight of the water purifier is 4.2Kg, and dimensions are 375 x 230 x 330 mm.

Kent claimed that the storage tank capacity is 22 liters, but there is no Home water purifier that is capable of storing 22 liters of water.

Filter Cartridges include stainless steel mesh, sediment, and activated carbon filter. The Kent Gold can remove bacteria and viruses from the water, and you get water that is better than the boiling water.

Kent has also employed a UF membrane to double the purification process and ensure the water is free from all the suspended impurities.

On the whole, the Kent Gold non-electric water purifier is compact and works well with municipal water that is free from dissolved impurities and hard metals.


4. HUL Pureit WPWL100 Classic 23-Litre Water Purifier

Pureit WPWL100 from Hindustan Unilever Limited is one of the best-selling non-electric gravity-based water purifiers in India.

Things to Know about Non-Electric Water Purifiers

Most of the Non-Electric water purifiers are based on the Ultrafiltration technology which does not remove the dissolved impurities. So, these water purifiers are suitable for use where inlet water has low TDS.

The UF water purifiers have a Micro Membrane and the pores of the UF membrane are very small, and they do not allow the bacterium or cysts to pass through. The Non-Electric water purifiers give Pure drinking water that is better when compared with the boiling of water.

No, Matter you buy an RO water purifier or a UF water purifier, you have to spend a few bucks every year on the Maintenance of water purifier. But, the cost of Maintenance of a UF water will be lower when compared with other purification systems.

Boiling of the water also requires cooking gas. Some of us opt for a Bottled Water Can that costs a lot more when compared with the Pureit, Kent or Tata Swach Germ Kill Kits.

If you are looking for a Fully Automatic UF water purifier, you can opt for Kent Smart 7-Litre Non-Electric Online UF Purifier. The Kent Smart UF needs to be connected to running tap water, and you don’t have to fill the water manually.

Water has to be filled Manually 2-3 Times a day for all the other Gravity Based non-electric water purifiers like Kent Gold, Cristella Plus or Pureit Classic.

The Average flow-rate of the Non-Electric Water purifiers depend on upon the Quality of the water and may also vary with the life of the Germkill processor.

The Non-Electric UF Water purifiers remove materials like oil, Sand, Clay, Dirt, pesticides, plant waste and also improve the taste of the water. However, these water filters can not remove Metals like Sodium Chloride, Calcium, Arsenic, Magnesium, and Lead.

Always, Drain out the first batch of the water when you buy a new water purifier. Even though the water is completely safe, it might have a distinctive taste.

The Plastics that are used to build the Non-Electric water purifiers that I have mentioned above are food safe, non-toxic engineering plastics that will not impart a smell to the water.

These are some of the Best Water Purifiers in India that works without electricity. If you have any queries regarding water purifier selection, post them in the comments section below, and I’ll be glad to answer them.




    • First of all, I would like to correct your description about “Kent Smart” where you have mentioned, “Kent Smart uses a very fine 0.1 Micron-sized UF membrane”. The actual pore size of the UF membrane used in Kent Smart is 0.01 micron which is so tiny to pass any harmful micro-organism.

      Both Kent and Eureka Forbes technology is good, but I personally prefer Kent technology used in Gravity Water Purifiers. The reason is:
      1. NSF & WQA gold seal Certification
      2. Fully automatic with auto-on and auto-off functionality
      3. Chemical free purification
      4. Leakage proof and
      many more..

      If your budget is low you can go for Kent Gold Plus which is even cheaper than Kent Smart.
