Gravity water purifier is an affordable and efficient solution for clean drinking water. However, if your home’s water supply is not provided by municipal corporation, then we recommend to choose RO water purifier.
These water purifiers use UF (ultra-filtration) technology to remove impurities (sand, dirt, dust and chlorine) and microorganisms like cysts and bacteria. They come in several sizes, require less maintenance, cost effective and work without any electricity.
To choose the best gravity water purifier, we recommend to consider couple of factors…
Water Tank Capacity
It usually depends on number of family members. For couples or bachelors, 10-liter water capacity is enough. For medium families, we recommend to go for 15 liters’ capacity. And for large capacity, 20 to 25 liters’ capacity is suffice.
It varies from one purifier model to another, usually ranging from 5 liters per hour to 120 liters per hour. Typically, a person drinks 2.7 liters per day or 3.7 liters if you include beverages and cooking. Based on this calculate the peak household water usage and choose according to it.
Filter Life Capacity
Filters have to be replaced after processing certain amount of water. So, you have to check the filter life capacity thoroughly and calculate how often you have to replace the filter. Decide if the replacement frequency is ok for you or not. On an average, filter life is around 1500 to 4000 liters of water.
Most popular materials of gravity filters are stainless steel and plastic. Stainless steel is most preferred as it is more durable and safer. However, it is expensive. Plastic material is more affordable but less durable.

How to Choose Non-Electric or Gravity Water Purifier?
Gravity water purifier is most economical way of drinking pure water. But while purchasing a water purifier, you have to consider certain factors and specifications. We have mentioned them clearly in the buying guide mentioned below. Read it thoroughly to make a wise decision.
1. UF Water Purifiers
They are also referred as gravity-based water purifiers or non-electric water purifiers as don’t need electricity for operation. As they don’t need charge-up cost, these purifiers are inexpensive. The term UF represents ultra-filtration which means the filter membrane contains is a lumen of fibers with holes sizing (10 microns, 0.1 micron and 0.2 micron). It can trap impurities like dust, dirt and others within its fibers. Some gravity water purifiers are light in weight and easy to carry, making them travel-friendly.
2. Water Holding Capacity
You have to analyze this factor based on the number of family members and daily water usage. Water holding capacity is usually measured in terms of liters.
- 10 liters is suitable for bachelors and couples.
- 15 liters is good enough for medium families.
- 20 to 25 liters is sufficient for large family.
Gravity water purifiers contain two filters – raw and purifiers which is mostly divided in equal share. For instance, if the water holding capacity is 18 liters, then raw filter will have 9 liters and purifier will have 9 liters.
3. Purification Levels
Usually, gravity water purifiers come with multiple purification stages. Each of these stages has a definitive purification technique. For better quality of purified water, it is better to have more number of stages. Some of the common purification stages are mentioned below…
- Pre-filter or Microfiber Mesh – It is usually present near the uppermost tank. It removes large particles like dust, mud, and sand.
- Activated Carbon Filter – This is an important filter as it removes invisible impurities, minute particles and chemical contaminants. It is capable of removing bad odor, colors of water, pesticides and parasites.
- Post-Carbon Filter or Polisher – It re-filters the already purified water to make sure it is crystal clear.
4. Purification Rate
It provides insights on how much clean water the purifier can provide in one hour. Most of the gravity water purifiers in India have purification rate from 5 liters/hr to 120 liters/hr. Water purifiers with 5 to 10 liters per hour purification rate is the most preferred option.
Most of the non-electric water purifiers are built using high quality ABS plastic or stainless steel. These two materials are widely used, preferred and recommended options as they are more durable compared to others. Some low quality plastic made purifiers are also available in market. If you choose them, we recommend to avoid keeping them away from direct sunlight as it can affect the longevity of the purifier.
6. Tank Type
Having a transparent tank helps you know when the tank is empty or need filling. You can choose close tanks as well like stainless steel, but you have to check the water level regularly by opening its cover. This can be irritating task for some people.
It represents the total amount of compounds both organic and inorganic in contaminated water. Usually, it is measured in terms of PPM (parts per million) or Lg/L. If the purifier is capable of removing enough TDs in water, then you can get pure water free of harmful chemicals. Gravity water purifiers are suitable for localities with low TDS levels below 300ppm.
8. Filtration Capacity
It represents the amount of water a purifier can filter in its lifetime. We recommend to look for a gravity purifier that can filter around 1500 to 4000 liters of water as it will require change of filters every month or 15 days.
9. Microporous Candles
These filters are commonly referred as ceramic candles. They are usually available in stainless steel water purifiers. In most of the gravity water purifiers, they are available in three numbers. These candles are capable of filtering 1 to 2 liters of water per hour, which is slower than UF technology but they are very affordable than other options.
When you are using these candles for the first time, you have to place them in a hot water basket for at least 6 to 8 hours to open their pores. This will ease up the purification process. For a week, the water may move a bit slowly but it will gradually increase. Though, they take some time for filtering, gravity purifiers provide clean and healthy water.
10. Maintenance of Filters
Based on filtration capacity, lifespan of filters ranges from 6 months to 3 years. However, you have to change them before completing their lifespan. If not, you will get unpurified water. Cleaning the filters once in every two weeks will increase their lifespan.
Knowing about the dimension of the purifier or the space it takes is an important aspect. Based on this, you can decide where you can place the gravity water purifier (on the kitchen platform or any other room). Usually, 23 x 56 x 33.5cms is sufficient enough in terms of both space and water filtering.
Some gravity water purifiers come pre-assembled so you can simply place them wherever you want. But some purifiers need to be installed. You can check out the instructional manual or YouTube video provided by the manufacturing for completing the installation process.
This factor plays an important role in the selection process of gravity water purifier as it represents durability of the product. On an average, most of the manufacturers provide 6 months to 2 years warranty on gravity based water purifiers.
Compared to electric purifiers, non-electric water purifiers (gravity based models) are very affordable. On average, their prices ranges from Rs. 1000 to Rs. 5000.
What is a Gravity Based Water Purifier?
Unlike several water purifier models in the market, gravity based water purifiers don’t use electricity. That is why, they are also referred as non-electric water purifiers. For purification process, they either use activated carbon or UF (Ultra Filteration).
Activated carbon is made up of small carbon granules which are capable of absorbing impurities available in water. When it comes to ultra-filteration, it is a membrane with bunch of hollow fibers. When the water is passed through these mesh or membrane, the impurities will stick to the how fibers and only pure water molecules are passed through it.
They are best suitable for purifying water supplied by municipal corporation water or locally piped water as they have TDS levels less than 300 ppm.
How Does a Gravity Water Purifier Work?
As the name implies, water is filtered using normal gravitation force (higher point to lower point) without any external help or force. This is why, they don’t need electricity for the purification process. Water is poured into top compartment which will flow into bottom compartment through the filters. Some of common filters used in these purifiers are micro fiber mesh, activated carbon and polisher which removes residual chemicals.
- Micro fiber mesh – It removes impurities, dust and visible pollutants.
- Activated carbon module – removes dirt, pesticide impurities and parasites.
- Polisher module – undissolved chemicals and chlorine are removed.
Some gravity based water purifiers come with UF technology which filters water using UF membrane. This membrane contains tiny pores (0.01 microns) which is small enough to remove bacteria, cysts and other microorganisms. We recommend to go for a model with this filteration process.
To conclude, water purified by gravity filters are much better and healthier to drink than boiled or chemically purified water. If you water supply source is municipality or corporation water, then you should aware of that this water is chemically treated. And it is supplied through taps, it doesn’t contain any harmful impurities like arsenic. So, gravity water purifiers are the best and cost-effective option.
Benefits of Using Gravity Water Purifiers
There are several advantages of investing in a gravity water purifier. We have mentioned some of them below for your reference.
1. Easy to Use and Maintain
Gravity water purifiers are very easy to use as they don’t have challenging assembling or installation process. Once you purchase the purifier, place it on kitchen platform or any corner. Add water to its top compartment and it will slowly filter the water.
When it comes to cartridges, they have a very long guarantee. So you don’t have shell out money or time on servicing or maintenance of filters. And moreover, there is no hassle of changing the cartridges frequently. They are suitable for both villages and cities as main water supply will be from municipality corporation. However, make sure the TDS levels in water are less than 300ppm.
2. No Electricity Needed
Gravity water filters usually work based on the water level pressure. This why, they don’t require any electricity for filtering or purifying the water.
3. Ample Storage Capacity
Most of the gravity water purifiers in India come with ample storage space. So, you can happily use them without worrying about the power or continuous water supply.
4. No Water Wastage
Unlike their counter models, gravity water filters don’t waste more water. When you consider RO water purifier, it discards 3 liters of water for providing 1 liter of filtered water. This means that 75% of water is wasted for 12% of purified water.
Some water purifiers use chemicals for providing clean drinking water. However, these chemicals can be harmful to your skin as well. So, we recommend to choose a model that doesn’t use chemicals for purification. UF is such water purification method which is usually available in gravity water filters.
6. Cost Effective
Yes, compared to several water purifier models provided in the Indian market, gravity water purification models are much affordable. Even best and high quality gravity water purifiers are available in price range from Rs. 1000 to Rs. 5000.
Drawbacks of Using Gravity Water Purifier
There is only one main disadvantage of gravity water purifier – it cannot purify water that has TDS levels above 300 ppm. So, they are not suitable for homes where water is not supplied by municipal corporation (as they have less TDS levels).
Important Tips to Consider While Using Gravity Water Purifier
- Once the installation of new gravity water purifier is completed, you have to drain out the first water batch completely as it will have a distinctive taste of carbon granules.
- Every gravity water purifier has notification alert feature which lets you notify about the cartridge refilling. If not, then it will stop working and water will start leaking out from the purifiers. So, we recommend to change it for continuous and proper purification.
- While changing or cleaning the filter, we recommend to check out for leakages. If you see any leakage, then replace with a new one.
- Make sure to clean the storage tank once or twice in a week for clean water.
- If the purified water has not been used in 2 days, then we recommend to discard the water and fill it again with fresh water.
- Never use boiling or hot water for purification. We recommend to use only cold water.
- Make sure to keep the purifier away from direct sunlight as it can damage the plastic and increase the algae growth.
- Avoid scrubbing the tank using metal mesh or fiber scrubber. Use soft cleaning materials like sponge.

You have to follow this procedure at least twice a month. Re-assemble the parts the again. Once the cleaning is completed, discard the first batch of water to remove any impurities left over in it.
UF is a filtration membrane process which uses hydrostatic pressure for forcing the water through semipermeable membrane. It removes all the colloidal particles like 0.01 to 1.0 microns from water and largest dissolved contaminants.
Gravity water purifiers use sedimentary filters or UF filtration for removing particles. Some of them also have activated carbon purifiers which remove impurities. They don’t require any electricity or continuous water supply for working. However, they cannot remove total dissolved salts and chemicals present in water.
When it comes to gravity water purifiers, they have multiple purification layers and RO (reverse osmosis) filter. They are capable of removing all kinds of impurities including total dissolved salts and chemicals like arsenic. However, the water wastage is high in RO systems as it produces 1 liters of water and discards 3 liters of water on an average.
