Best Water Purifier Buying Guide
The best water purifier provides safety from waterborne diseases like cholera, dengue, and other viral fever, etc. So before purchasing it is important to focus on the key factors like cleaning technology, capacity, and filters. These factors help in improving the quality of water.
As a vital resource for all life, access to pure water is essential. The knowledge of what type of filter to use can ensure health and longevity. And for this reason, it is important to select the right system of filters based on the source of the drinking water. Let’s look at all three possible sources: municipal water, ground water, and water from mixed sources.
Source of Water
First priority while choosing a purifier will be given to the cleaning technology, which completely depends on the supply of water at your place of existence. This is because different water supply comes with various chemical compositions either can be tap water, borewell, ground or municipal water.
Quality of Water
Quality of water should be safe with the dreadful disease. This could be done by measuring the pH and the TDS level.
Since it is not possible to check all the parameters so one can measure the Total Dissolved Salts by TDS meter.
Technologies Used in Modern Water Purifier
UF (Ultra Filtration) Technology
Water having low TDS is supposed to be suitable. Most of the gravity-based water purifiers have storage tank that can store water up to 13 litres.
- Only Type Of Water Purifier Certified To Remove Cysts
- Works Without Electricity
- Does Not Remove Dissolved Impurities
- Not An Absolute Barrier To Viruses
- Disinfection Recommended
UV (Ultraviolet) Technology
UV rays penetrates the microorganism’s outer cell membrane and passes through the cell body that disrupts its DNA, hence preventing reproduction.
- Does Not Alter Water Chemically
- Sterilized Microorganisms Are Not Removed From The Water
- Does Not Remove Dissolved Organics, Inorganics Or Particles
- Fast Disinfection Process
RO (Reverse Osmosis) Technology
This technology is used to make bottled water. It is also stand alone technology that is capable of desalinating seawater and making it drinkable.
- Most Convenient And Effective Method
- Effective When TDS (Total Dissolved Salts) Rating Is Between 200 And 2000
- Reduces The Hardness Of Water Which Is Caused By Excessive Calcium & Magnesium Salts
- Purifies Water Of Contamination Caused By Fluoride Or Other Harmful Chemicals And Heavy Metals, Such As Arsenic, Lead, Mercury
TDS-Total Dissolved Salts of Water
TDS measures the softness or hardness of the water in PPM. Its major components are phosphate, calcium, mercury, cations, and anions etc. Substances like lead, cadmium, arsenic only are eradicated by RO purifiers.
TDS meter will basically allow checking the level of TDS (PPM) present in the water. The table here gives you a clear thought about the TDS level and range of water. Have a look.
|TDS Value Parts Per Million||Rating|
|50 – 150||Excellent|
|150 – 250||Good|
|250 – 300||Fair|
|300 – 500||Poor|
Types of Water Purifiers
Electrical Without Storage Purifier
Electrical units are also available without a storage tank. This type is quite popular – many units through the ’90s were of this type. Useful in places that have a steady supply of electricity through the year, the filtration quality is the same as of those with storage.
Electrical With Storage Purifier
Electric water purifiers are always connected to the water supply and run on electricity. They use sediment filters and activated water filters with UV or RO purification systems, which require electricity.
Non-Electrical With Storage Purifier
These water purifying units have storage tanks to store water after it is purified through sediment and activated carbon filters. Useful in places where water supply is unreliable.
Non-Electrical Without Storage Purifier
Made of food-grade plastic, these water purifiers are directly fixed to the water tap. They are usually candle-shaped filter units that consist of a resin filter that has to be replaced once a month. They’re UF and Activated Carbon filters that run without electricity.
There are also personal water purifiers – water-bottle-sized, optimal active units that attract and remove waterborne pathogens. They are great for pure water anywhere, anytime, owing to their traveller-friendly size.
Types of Water Purifying Technologies
Without having sufficient information, no one is confident that which purifier is best in the market. So note down some of the features which one should keep in mind before purchasing.
- Reverse Osmosis (RO)
- Ultraviolet (UV)
- Activated Carbon
- Gravity Based or Candle Filter
- Ultrafiltration (UF)
- Warranty and Installation
- Reliable Brand
- Electric or Non-Electric
Water Purifier Features
Below we have given some additional features to keep in mind while buying a water purifier.
Flow Rate: Bacteria easily escape from the purification system, if the flow rate is high and if the flow rate is low then it will consume a lot of time.
Weight: Weight is a major factor that should be considered.
Body: The body should be attractive, rustproof, easily goes with kitchen decor and durable with durable materials like aluminum. But for safety purposes use steel.
Global Certification: The purifier should have a global certification like WQA(USA) and Seal Mark for RO or UV.
Display: Purifiers come with tank full, empty, on/off indicators. Some highly advanced purifiers have fault alert, TDS levels, and filter change, etc.
