Types of water purifiers
There are a variety of water purifiers available today to meet different requirements and every budget. Their cost can range from Rs.1,000 to over Rs.50,000 and even more based on the one you choose. You will have to do your homework here and find out about the different types available in the market today and which one solves your purpose. Most of the water purifiers today work on the following techniques and some even use a combination of two to deliver better results:
In candle filter, contaminated water is purified by passing it through a candle that sits on top of a plastic.
Candle filters have two reservoirs that sit on top of each other. The top reservoir consists of either one or two ceramic candles upon which contaminated water is poured. The water is passed through that candle which has tiny pores. Any impurity which is bigger than the pores gets blocked out. The clean water is stored in the low reservoir safely. It doesn’t involve the use of electricity. However, you should know that the purified water is not completely devoid of impurities. It still may contain minute impurities like viruses. Also, the filter candle is made up of resin material which needs to be changed on a monthly basis. Some candle filters even incorporate the use of activate carbon to deliver better results.
- Low cost.
- Ideal if you live in an area which requires the lowest amount of filteration
- No high maintenance
- Requires simple operation
- Stores clean water safely
- Needs no electricity
- Requires frequent cleaning of candles
- Not the most effective purification process
- Takes a long time to remove impurities from water
- Candle needs to be replaced frequently
Activated carbon filters
Activated carbon filters work on the fundamental of employing activated carbon to eliminate pesticides, chlorine and other chemical substances to a very good extent. When water is passed over the activated carbon surface, the contaminants get drawn to the surface of the carbon filter and this is how they produce potable water. They are also quite effective in altering the taste and odour. There are filters that combine this technology with UV technology too. Filters that use only activated carbon do not need electricity.
- Ideal for people who live in areas where there are frequent power cuts
- A better solution than Candle filters without breaking your bank
- Low initial cost
- Not as effective as UV filters against bacteria.
- Need to be replaced frequently.
- Alters the taste and odour.
Chemical based filters
Chemical based filters involve the use of chemicals like chlorine tablet and pure iodine crystals for making the water fit for drinking purpose. Since Chlorine is a highly efficient disinfectant, it kills viruses, bacteria and other contaminants too. But the taste of water also gets changed here. However since they do not require electricity for functioning, they should be your ideal choice if you live somewhere which has frequent power cuts.
- Quite effective in killing viruses, bacteria and other diseases causing pathogens
- No need of electricity
- Budget friendly method
- Not the most effective form of purification
- Taste of water gets changed
UV Technology filters
UV-based systems have the ability to destroy 99.9% harmful microorganisms without affecting the taste and odor of water. In UV water purification technique, impure water is exposed to UV rays which kill even the smallest of all molecular impurities such as bacteria, viruses and tiny solids. This is one of disinfection methods which are approved by the FDA, United States. Some purifiers work on the mechanism of bulbs and some on lamps. Usually they also combine activated carbon filter and reverse osmosis technology.
- Eliminates all microorganisms
- Does not alter the taste, odour or pH balance of water
- Not quite effective in killing harmful substances such as heavy metals or Volatile organic compounds.
- Requires electricity and running water for functioning.
- Requires timely servicing
Now comes the most expensive technology for domestic water purifier. A reverse osmosis water purifieremploys two carbon filters and a very thin membrane for the purpose for being used as a third filter. It involves multiple purification stages to provide you potable water that is high in quality. It kills microorganisms and other harmful elements as well as improves the taste and odour of water. However you should know that RO also filters out the essential minerals which are good for health. They should be your ideal choice if where you live receives hard water. They can be fitted under the counter beneath the kitchen faucet and even on wall. The most advanced and popular combination these days is that of RO with UV and UF which gives the purest form of water.
- Provides the highest quality level of drinking water.
- Removes all types of impurities
- Improves taste and odour.
- Very expensive.
- Eliminates minerals which are good for health
- Slow filtration process
- Requires regular servicing
Based on Body type
The material which has been used for construction of a water purifier is also very crucial.
Steel is considered as the best material as it doesn’t interferes in the filtration process or reacts with any impurities. It is extremely safe and durable.
Aluminium is considered as an inferior option here as it reacts with the salts and minerals in water and oxidizes the quality of water, thereby making it even more unsafe.
Based on use of electricity
Purifiers are both manual and electric. If you stay in an area where there are frequent power cuts, it is better that you opt for non-electric water purifiers. There are two types of non-electric water purifiers as listed below:
The online types are usually fixed to the mouth of the tap and contaminated water is purified directly as it runs. Plus since they are portable, they make for a travel friendly option too!
The offline types are also known as water filters and use a mixture of activated carbon and sediment filters. Clean water can be easily store in them.
