Things to Consider Before Buying Best Water Purifier for Your Home

Water Purifier

Storage Capacity

The purification capacity as listed on the packaged box is always 1500 ppm, and it shouldn’t be less than that. There are purification indicators present in water to warn the customers against the quality of water that the purifier is supplying.

Water purifier manufacturers provide a tank that collects water while purification. For a nuclear family with 5 to 7 members; purifiers with the capacity of 6 liters are sufficient. Thus you get purified water as and when needed.  Popular or reputed companies use high-grade plastics. 

Water Quality

As a customer one should always examine the quality of water supplied by the purifier before even purchasing it. Some of the companies indeed sell pre-owned products that the buyers are not aware of.  

The excellent quality of the water ensures proper health and keeps you safe. The cartridges present in the water purifier helps in softening water.


  • E. Coli Virus: – This bacterium is found in the bodies of birds and animals. E. Coli may be present in water in forms of feces or sewage contaminants. Drinking water infected with E.Coli can cause diarrhea and other series of diseases.
  • Bacteria: – Heavy downpour, wear, and tear of systems are some of the causes for water to be contaminated with Bacteria. Drinking water contaminated with bacteria is considered to be fatal.
  • Pesticides and fungicides
  • Chlorine: – To purify water and make it suitable for drinking; chlorine is often mixed with water. Drinking chlorinated water can cause severe joint pain. 
  • Nitrates: –   Nitrates promote plant growth and are thus excessively used in agriculture. Drinking such water can lead to Blue Baby Syndrome; reducing the ability to carry oxygen in the blood.

Water Pressure

Testing for water pressure is necessary before purchasing a purifier. Most of the purifiers need pressure between 5 to 40 (pounds per square meter) to work efficiently. You can check the pressure just by calculating the distance between your floor and the terrace where water is uniformly distributed by gravity. If you are residing in an apartment or a 10 story building and you live on the 7th floor then the pressure on your tap will be 15 PSI (for every 10 feet from the terrace PSI is equal to 5 PSI,)

For homes having low pressure, it’s better to buy a booster pump or UV water purifier like Alfaa UV’s e-Water Purifier that works on low tank pressure

Power Supply

Power Supply or Electricity is another metric that the customer needs to think of before buying a purifier. If there are regular power cuts in your area; you may choose a purifier with storage. These water purifiers work on gravity rather than electricity.

Reverse Osmosis

It includes a stream of water or other solvents through a semi-permeable membrane. That blocks the dissolved solutes present in the water/solvent.  Solutes include ions, pesticides, and some other chemicals. Many plants that deal with water filtration follow this mechanism. 

Ultra Filter

This process involves the application of hydrostatic pressure to force water against a membrane. This membrane can filter harmful microorganisms and bad odors in the water. The concept of Ultrafiltration is closed to RO except in the size of the molecules that it retains or holds.  Colloids, bacteria, and pathogens that are larger than the pores of the membrane get filtered by this membrane. 

Ultra Violet Filtration

It involves the application of a UV lamp; that purifies water and makes it suitable for drinking. The UV light used in this process is termed as UV-C or germicidal UV. The UV radiations modify the genetic materials of the microorganisms such that they can’t multiply. The pre-treatment process maximizes the effectiveness of the treatment process.

The pre-treatment process allows the passage of water through sediment/carbon filters. Silt gets removed through the sediment filters; organic impurities are removed by the carbon filters. 

Frequently Ask Questions

What is water purification?

Water purification is the process that involves the filtering of unwanted chemicals, toxins, suspended solids, and gases from water. It is done to make the water fit some specific purposes.  Mostly it is done to disinfect water for human consumption (for consumption). Water purification can be done through medical, pharmacological, and chemical ways. 

With the use of modern technology like RO, UV, and UF water can be purified and made suitable for drinking.

Why do you need Water Purifier?

You can survive without food for days, as your body will start utilizing stored fat and protein to prepare its energy. But if you cut off the water supply, you’ll be dead within days.

Even our bones contain about 25% of water. On average, we need 2.4 Liters of water per day. Water being so vital to our lives, it’s not surprising that we like it clean, tasty, and pure.

One reason for which people spend money on purifiers is that they remove bacteriological contamination from water.

There are different kinds of water filtration processes –like RO Filtration, Ultra Filtration, UV Filtration, and so on.

You need to choose a water purification system depending on the quality of the water. It is helpful to know how these systems operate. So let’s learn them in detail.

How does Water Purification System Work?

RO or Reverse Osmosis Filtration System is a simple water filtration mechanism. It includes a passage of water and other solvents through a semi-permeable membrane.

This removes contaminants like ions, pesticides, microorganisms, and other chemical compounds from water. These are the elements present in the RO System. An RO Purifier is best suited for industrial as well as domestic usage.


Sediment filters and carbon filters are commonly used ones. These remove chlorine, dirt, and other sediments present in water.

RO Membrane

These help in removing contaminants from water. Water enters into the storage tank after this stage of purification.

Storage Tank

This purifies treated water. The storage capacity of the tank varies, so you need to check usage before choosing a water purification system.

Post Filter

This is a carbon filter. These filters are used to remove bad odor and improve the taste of water.
