Water purifier buying guide – Things to watch out for  

Water purifiers promise safe, easily accessible drinking water for a fraction of the money you spend each year on bottled water. However, with so many variants of purifiers promising the cleanest output, how do you go about choosing the right on?

Some of the most important factors to consider before investing in a water purifier are the quality of water and the purification method it requires. Our water purifier buying guide will help you to choose one that is best for your need, without compromising on quality.

Here’s what you need to know before you selecting the water purifier that’s right for you.


Step 1: Understanding water purifier variants 

Water Purifier - Types of filters

Water purifiers with gravity filters

These type of purifiers use the simple technology of pressure filtration to purify water. Water moves down from the higher chamber to the lowest one, and inbuilt filters remove dust particles and dissolved salts in the water.

Our water purifier buying guide recommends: Pureit Classic 23 L Gravity Based Water Purifier

Pros:

  • Inexpensive and does not require electricity for filtering
  • High water storage capacity (Ranging from 7 to 20 liters)
  • Portable and can be moved around easily (in case of picnics or road trips)

Cons:

  • Cannot protect you from germs and microorganisms
  • Cannot filter heavy metals like mercury and compounds like nitrates 

Water purifiers with activated carbon

Carbon granules in these filters are positively charged or infused with silver molecules. This means that they can remove pesticides and herbicides, chlorine, radon and other chemicals. These filters are rated by the size of particles (measured in microns) that they can remove. So, a 0.5 micron filter is more effective than one that measures 10 microns.

Our water purifier buying guide recommends: Livpure Touch 2000 8.5 L RO + UV Water Purifier

Pros:

  • Cost-effective. Some are small enough to be attached directly to the tap
  • Does not require power to operate so you save on the electricity bill

Cons:

  • Ineffective against bacteria, viruses and heavy metals

 

Water purifiers with ultraviolet filters

These purifiers use UV radiation to deactivate water-borne, disease-causing organisms. They are an ideal hybrid between the affordable activated carbon filters and the more expensive RO (reverse osmosis) systems.

Our water purifier buying guide recommends: Aquaguard Classic UV Water Purifier

Pros:

  • Uses the same amount of energy as a 60-Watt light bulb so it keeps your electricity consumption low

Cons:

  • Does not offer storage
  • Unable to remove heavy metals or chemicals like arsenic, nitrates and iron
  • Can’t get rid of the smell of contaminated water

 

Water purifiers with ultrafiltration

UF water purifiers use an ultrafiltration membrane to purify water of all germs, bacteria and viruses, and flush them out completely. The pores of the UF membrane are larger compared to the RO membrane, which means they are effective in purifying water from public supply that does not contain dissolved salts.

Our water purifier buying guide recommends: Kent Gold Star 22 L UF Water Purifier

Pros:

  • Does not require electricity to purify water
  • Best for removing germs and impurities from cloudy and muddy water
  • Low maintenance since UF water purifiers can be cleaned manually by flushing all blocked germs and dirt

Cons:

  • Not as effective as RO water purifiers because they have slightly larger pores that cannot block dissolved solids and salts from water
  • Effective only for water containing low TDS (total dissolved solids) levels, which does not contain dissolved toxic impurities like heavy metals

 

Water purifiers with reverse osmosis (RO) filters:

This form of water purification involves forcing water through a semipermeable membrane, which filters out water contaminants. Such purifiers are known to remove arsenic, nitrates, sodium, copper and lead, some organic chemicals, and fluoride.

Our water purifier buying guide recommends: Whirlpool Minerala 90 Platinum  8.5 L RO Water Purifier

Pros:

  • Effective in purifying water whose contamination levels by chemicals is high

Cons:

  • Not as effective as the ultraviolet filters against bacteria and viruses

 


Step 2: Consider the water quality

Water purifier buying guide

Soft water

Do you live in an area where the water supplied by the municipality is from surface sources (rivers and lakes)? If your answer is yes, chances are it doesn’t have a smell and that its TDS (total dissolved solids) level is low. This means that you need protection from mostly microbiological impurities like bacteria and viruses. Under such circumstances, go for a simple activated carbon or UV water purifier.

Hard water

If the water available for drinking in your area is saline or hard, or if you have to use underground water, choose a reverse osmosis (RO) based water purifier. The membrane it uses measures barely .0005 micron and can remove the minutest of impurities. These purifiers are also capable of getting rid of foreign flavor in the water.

 


Step 3: Find out the contamination level

Water purifier buying guide

Water supplied from lakes, rivers, and harvested rainwater has a lower concentration of TDS. Alternatively, those from borewells or supplied by tankers has a high TDS and chemical concentration. If the total dissolved salts in water exceed 80 PPM, experts recommend RO-based water purifiers. Otherwise, you can buy a standard UV-based purifier. Want to check the water quality in your area? There are labs in almost every city that test it. Click here for a comprehensive list of labs.

 


Step 4: Check the water pressure

Water purifier buying guide

Both UV and RO filters need water to be supplied to the system. If the incoming water flow does not have high pressure, an RO filter will not work optimally. So if you do not have such a facility or if the water supply is erratic, you can attach a pump, such as the BalRama RO Booster Pump Motor to the RO filtration unit to boost the pressure. You may also opt for activated carbon purifiers.

 


Step 5: Think electric or non-electric

Water purifier buying guide

Electric water purifiers

Such purifiers have a greater chance of giving 100% clean and purified water than non-electric ones. However, they cost more and require power 24/7. RO water purifiers are said to be the most effective electric purifiers, but are useless in areas where power is erratic. The same is the case with UV water purifiers.

Non-electric water purifiers

If you are living in an area where electricity is a problem, then non-electric water purifiers are your best bet. They are easy to use, easy to maintain and cost less too. Many models are also portable, which can help of your lifestyle demands that you carry drinking water on the go. However, while they can remove most of germs and impurities from water, they aren’t as effective as electric water purifiers. Opt for an activated carbon water purifier as it is the most compact and needs no electricity to operate.

Step 6: Choose the ideal capacity

Water purifier buying guide

Generally, the storage capacity of purifiers can range between 4 and 25 liters. If you don’t have the patience to wait for a bottle to fill up, ensure that you get a water purifier with good storage and auto refill facility. You can go for carbon purifiers, like the Kent Gold Cool 20 L Water Purifier, which offers storage of 20 liters. If you have a family of four, then our water purifier buying guide recommends a purifier with 6-7 liter of water storage, such as the Kent Maxx 7 L UV + UF Water Purifier.

 


Step 7: Decide the location of your new water purifier

Water purifier buying guide

Your new water purifier requires an electrical point with earthing and should be set up near an outlet of drinking water. Most apartments and homes today come with a special water outlet near the kitchen sink where your purifier can be easily installed. The ideal distance between the purifier and the electrical point should be around 3 feet. Ensure that the location you choose in your home is away from direct heat or sunlight. If space is an issue, or if you would like to keep your counter space in your kitchen empty, opt for a wall-mounted purifier like the Aquaguard Crystal Plus UV Water Purifier
