What’s the difference between an Electric and a Non-Electric water purifier?
Water purifiers without a doubt have become a fundamental part of our daily lives for clean and healthy drinking water. There are mainly two types of water purifiers in the market. Namely, electric water purifiers and water purifiers without electricity. These two types, as the names suggest, vary in their usage of electricity. But at the same time, also differ on several other factors like – water purification process, kinds of impurities removed, features and aesthetics, maintenance cost and so forth.
Electric Water Purifiers vs Non-Electric Water Purifiers
Electric water purifiers mainly comprise of Reverse osmosis (RO), Ultraviolet (UV) and a combination of both - RO + UV water purifiers. These are more sophisticated in their technology and use various types of water filters to provide pure and clean drinking water. They have better water purification efficiency and come with several other attractive features.
How do water purifiers without electricity work?
Water purifiers without electricity operate using gravity-based or manual filtration systems. Gravity-based purifiers often feature a combination of activated carbon, sediment filters, and sometimes ceramic filters. These elements work together to remove impurities and contaminants from the water as it passes through them due to gravitational force.
Manual filtration systems may involve physically pumping or pressing water through various filter layers. The filters could include materials like activated carbon or ceramic, effectively trapping particles and purifying the water.
In both cases, these systems don't rely on an electric power source; instead, they utilize natural forces or manual effort to provide clean and safe drinking water.
Experience uninterrupted access to clean water with our water purifiers without electricity. Designed for reliability during power outages, these purifiers ensure you have safe drinking water without dependence on electricity.
Let’s understand the key differences between the two.
Stages of Water Purification
Electric: Advanced 6 or 7 stages of purification
An RO water purifier with its advanced stages of purification, provides clean drinking water to you and your family. These purifiers can remove high TDS, chemicals, and heavy metals which cannot be removed using a UV or a non-electric water purifier. A typical RO water purifier includes - Sediment Filter, RO Membrane, Pre-RO Carbon filter, UV Chamber, Mesh Filter, Post RO Carbon Filter, and Micro Filter. A UV purifier on the other hand comes with around 4 stages of water purification, designed to use electricity to kill microorganisms like protozoa, viruses, and bacteria.
Non-Electric:3-4 stages of purification
These come with a much simpler purification process. Water is poured in the device from the top and with the gravitational pull it passes through sediment, carbon and micro filters arranged one below the other.
Purification of Different Sources of Water
Electric water purifier: Suitable for all sources of water
In India, one of the most common sources of water is borewell or ground water. The TDS levels of borewell water are usually higher as compared to other sources like tank or municipal. In cases where TDS levels are more than 300 ppm, RO water purifiers are the best solution as only RO technology can get rid of high levels of TDS.
Non-Electric water purifier: Suitable for only Municipal water
Non-electric water purifiers should be preferred when the TDS levels are under consumable limits and thus water is comparatively less harmful for consumption. Non-electric water purification systems can remove microbes like bacteria and pesticides along with bad odor but are incapable of removing heavy metals that are harmful if consumed in the long run.
Taste of water
Electric water purifier : Enhances taste to make it sweeter
Water collected directly from lakes or rivers is salty mainly because of the presence of minerals, salts and other organic compounds. RO water purification technology is best at treating water with hardness and turning it into soft, sweet tasting consumable water.
Non-Electric water purifier: Doesn’t improve the taste of water
The activated carbon filter present in non-electric water purifiers, remove contaminants and chlorine that can impact and sometime change the taste and color of water but doesn’t sweeten it.
Filter replacement
Electric water purifier: Needs replacement once in a year
Filter replacement in electric water purifiers should be occasional. RO and UV purifiers are built to require minimum maintenance.
Non-Electric water purifier: Needs replacement every 2-3 months
Non-electric filters need replacement every 3 months as they can get clogged easily. The frequent filter replacement can be inconvenient as this requires regular maintenance.
Features and aesthetics
Electric water purifier : Advanced features and aesthetics
Electric water purifiers come with superior aesthetics and newer designs that make your kitchen look more attractive. Pureit RO water purifiers not only offer beautiful looking purifiers but also are laden with best-in-class features like Advanced Filter Alerts, Water Level Indicators, Digital Purity Indicators etc.
Non-Electric water purifier: Basic features and aesthetics
Non-electrical water purifiers require space in the kitchen as most of them are table-top devices. They have only basic purification features and designs
Maintenance cost
Electric water purifier : Slightly higher maintenance cost
As an RO water purifier has a more efficient purification technology, it’s slightly expensive to maintain. The average cost of RO water purification comes to 50 paise per litre. But a UV water purifier on the other hand comes with the lowest maintenance cost at only 30 paise per litre.
Non-Electric water purifier: Lower maintenance cost
Non-electric water purifiers have a low maintenance cost at 35 paise per litre.
Device cleaning
Electric water purifier: Less frequent
Electric water purifier devices are built to require occasional cleaning that is only once in 12- 14 months.
Non-Electric water purifier: More frequent
Non-electric water purifiers require very frequent cleaning that is every 3 – 4 months.
In conclusion, each water purifier comes with its own features and benefits and thus should be assessed basis individual requirement. In places where there is already an effective water filtration system, a non-electric water purifier could do the purification job. Whereas if the TDS levels in the water are excessive or water seems to be more contaminated, electric water purification should be preferred.
FAQs
1) What is a water purifier without electricity?
Non-electric water purifiers are gravity-based water purifiers. They consist of sediment filters, carbon filters, and microfilters to purify the water. Gravity-based water purifiers do not require electricity.
2) What is an electric water purifier?
RO water purifiers, UV and UF filters, and RO + UV + UF are some examples of electronic water purifiers. They are designed with advanced multi-stage purification technology which requires electricity to function.
3) How much power (watts) does a water purifier use?
On average, water purifiers have power consumption between 25 watts to 60 watts depending on the type of water purification technology.
4) Is the water from a non-electric purifier safe for consumption?
The quality of water is the factor you should consider before deciding to choose a gravity-based water purifier or any electric water purifier. If the water has low TDS then a gravity-based water purifier is enough to filter the water. If the water contains a higher percentage of TDS then you must opt for an RO water purifier.
5) Which is the best water purifier without electricity?
Gravity-based water purifiers work based on gravity. The water filtration takes place through different stages in an automated fashion and the purified water settles below. Gravity-based purifiers are the best non-electric purifiers.
