Living a healthy lifestyle requires clean water to drink. Water quality varies in every locality, with some areas having hard water. For this reason, many households installed purifiers into their water systems.

Indeed, a water purifier is an important household item that significantly contributes to your family’s health protection. Thus, it is crucial to use a quality and reliable purifier to ensure that you and your loved ones are drinking fresh, clear and crisp water everyday.

If you are looking for a water purifier for your home, here are 7 things you should consider.

7 Features to Consider When Buying a Water Purifier

  1. Purification Process

There are several ways of purifying water, including boiling, chlorination, filtration and distillation. While many people think that the cheapest type is boiling water for at least 15 minutes, just think of the electricity or gas usage when boiling your water.

Here are the most common and energy-efficient water purification processes that you may want to look into.

  • Reverse Osmosis. This uses a semi-permeable membrane that acts as a filter to remove harmful pollutants. The downside to the RO process is that the water tastes bland since even the essential minerals are filtered from the water.
  • Ultraviolet Rays. To date, the use of UV purification has been the most reliable and energy-efficient process of getting rid of bacteria and viruses from water. Unlike reverse osmosis, the use of ultraviolet rays does not remove the essential minerals in the water while minimising water wastage.
  • Activated Carbon. The use of this process involves the absorption of harmful chemicals, sediments, and contaminants in water. In some cases, activated carbon filters are used as supplementary filtration for other purification processes like reverse osmosis and UV purification.

If you are looking for a reliable water purifier, it may be best to check if it is mechanised by any of these three or a combination of these purification processes.

2. Use of Energy Source

Some water purifiers work on electricity, while others function under the pretence of gravity. So, if you live in a place where power outages are rampant, it may be best to choose gravity-toiled water purifiers like ultrafiltration and activated carbon.

If you have an efficient supply of electricity, you may opt for purifiers with RO or UV functionality. Just remember to check the wattage of the unit before buying to ensure cost-effective use of energy.

3. Required Water Pressure

Besides the elevation of your building, water pressure can be affected by blocked pipes and clogged filters. Generally, a pressure of 5 to 40 psi is needed to keep an RO water purifier working effectively.

If you have low water pressure coming from your mains, it may be best to install a pump booster to have the needed water pressure. In case you want to keep the water pressure at a minimum, you may choose a purifier with activated carbon instead.

4. Elimination of Contaminants

The best thing about water purifiers is that they use combined technologies to decontaminate water, so every home can enjoy the goodness of fresh clear crisp water. You may choose from filtration and purification processes depending on the quality and condition of your water supply.

Below are the categories of contaminants that your chosen water purifier should eliminate:

  • Biological. These are bacterial microbes such as protozoa, water-borne viruses and other parasites.
  • Physical. These are impurities visible in the naked eyes that mainly affect the physical appearance of water like blurry hues in water. This type of contamination is typically the result of having sediments or organic materials suspended in water.
  • Chemical. These contaminants include salts, bleach and other chemical contaminants that are categorised as man-made.

When looking for a water purifier, make sure that it is an NSF-certified appliance so you can be sure of its performance.

5. Water Chiller and Heater

The latest innovations in water purifying systems include providing chilled and hot water whenever needed. As the world evolves, time is becoming so precious that waiting 15 minutes to boil water or 30 minutes to chill it is a total waste of time. However, with the latest water purifiers, you no longer need to wait for 15 to 30 long minutes just to have hot or chilled water.

6. Cost-Efficiency

The upfront cost of high-end water purifiers with hot and chilled water systems is, of course, somewhat exorbitant. However, nothing is more priceless than ensuring your family’s health and safety.

Essentially, you can go for regular purifiers that are more cost-efficient such as sediment filtration, activated carbon and other quality filters. You may also choose RO and UV-enabled purifiers for more energy-efficient water purification systems.

7. Plumbing Requirements

Another important factor to consider is the plumbing system that the purifying machine needs to operate productively. Check the size, that is, the hose diameter and length to ensure that connectivity provides functionality and reliability. You should also check that the inlet or outlet of your water supply will not result in water wastage.


These 7 features are important to ensure that you are buying the most efficient and reliable water purifier that guarantees safe, fresh and clean drinking water every day.
