Difference between an electric and non-electric water purifier
Many people think that the only difference between an electric and non-electric water purifier is the usage of electricity. The method of water purification is totally different.
An electric water purifier like UV uses UV radiations and RO uses the RO membrane to eliminate microorganisms. On the other hand, a gravity based ( non-electric) water purifier uses UF, activated carbon, sediment filter to catch the microorganisms, and other sediments.
|Electric Water Purifier||Non-Electric Water Purifier|
|UF Water Purifier|
Electric water purifiers like RO removes dissolved solids and convert hard water into soft water. The UV water purifier kills microorganisms.
You can also find water purifiers available in the market that use RO + UV Technology to give you clean softer drinking water free from contaminants and TDS.
As we all know non-electric water purifiers do not use electricity to purify the water, it uses water pressure or gravity as the power to purify it.
The sediment filter in the gravity based water purifier removes sediments and the activated carbon removes organic compounds, improves the taste of water, removes odour and other contaminants.
One of the major drawbacks of this type is that it does not convert hard water into soft water. If you live in an area where there is a hard water supply, then do not even think about buying a non-electric water purifier.
Who Should Get a Non-Electric Water Purifier?
Non-electric water purifiers are available in two types – gravity and UF which is suitable for tap water with a low TDS.
These water purifiers are cheaper when compared to electric purifiers. before you consider buying one remember that you may need to pour water into the purifier every time to purify it. this could be time and energy-consuming. Make sure to weigh your needs and then make a decision.
We recommend non-electric water purifiers two nuclear families living in areas where water is less contaminated.
Frequently Asked Questions
Do water filters kill bacteria?
Chlorine is used to remove bacteria and microorganisms from water. In the initial stage, water passes through a membrane or microfiber mesh that eliminates solids from the water. A specific quantity of chlorine is then added to this water to eliminate all microorganisms.
Then the excess chlorine in the water should be removed and thus it again passes through the activated carbon filter to remove chlorine to make it fit for drinking.
How can I naturally purify water at home?
Here are a few ways to naturally purify water at home:
- Using iodine tablets, solution or crystals
