All About Different Types of Water Purifiers

Updated by

Surely, we all know how important water is for our body. But clean water is not readily available everywhere since the purity and other aspects such as hardness, alkalinity, minerals, etc. vary from place to place. In that case, it becomes a necessary task for us to make the water suitable for drinking. The advanced Water Purifiers that we use these days are decent enough to do that for you.

Therefore, if you are planning on purchasing a new Water Purifier for your home, you better research it well before buying one since there are so many good options available out there in the market.

Aside from that, do you actually know how many types of Water Purifiers are there, and how they work to purify the water? If not, then stick around and thoroughly read this whole article as we are going to discuss all that here with you.

Not just that, we will also be comparing the different types of Water Purifiers and find out which one of them does its job the best.

Types of Water Purifiers

Since there are plenty of Water Purifiers available these days, we will go through the one by one and discuss both their advantages and disadvantages alongside. Basically, there are five kinds of Water Purifiers, and all of them use a different approach to attain the same goal, which is to purify the water.

RO & Advantages & Disadvantages

The name RO has been given to this type of Water Purifiers because of the purifying technique it uses, Reverse Osmosis. Such kinds of Purifiers have a thin membrane inside the purifying chamber through which pressurized water is passed through.

Because of the high pressure, the porous membrane only allows the small water particles to pass through only. In the process, the leftover particles that cause water-hardness and other impurities such as fluoride particles, lead, chlorine, arsenic, sulfates, and nitrates either get stuck inside the RO membrane or get left behind entirely. RO purifiers are one of the most well-known kinds of Water Purifiers that the majority of people are using these days.

Advantages:

  • Highly functional in removing hard particles and solids from water.
  • Other impurities such as bacteria, germs, microorganisms, and their residues are filtered well.
  • Significantly removes intoxicants from water and promotes good taste.
  • Maintenance cost is very less.

Disadvantages:

  • Cannot work without electricity.
  • Produces wastewater in a large quantity.

UV & Advantages & Disadvantages

Although RO purifying process is well-capable of filtering out germs and other disease-causing aspects. If you want to be extra sure and rely on some advanced technology, the UV purifiers will serve you the best. As per its name, these Purifiers consist of a lamp that throws UV rays during the filtration process to kill the germs and other microorganisms like cysts, bacteria, and whatnot.

You might wonder what happens to the dead bodies of such germs. Basically, such microorganisms are only harmful to drink when they are active. And, since they are already inactive after passing through the UV rays, there is nothing left for you to worry about. The residues are even filtered out afterwards, so all you will get from the purifier is fresh and ready-to-drink clean water only.

Advantages:

  • The Purification process is very quick as compared to other types of Purifiers.
  • The maintenance cost of UV purifiers is very less as you only need to replace the lamp once or twice a year.
  • Does not separate out essential minerals from water.
  • The overall energy consumption of the UV Purifiers is very less, similar to a light bulb.

Disadvantages:

  • A few of the germs’ dead bodies do remain in the purified water.
  • There is no such improvement in the taste of water.
  • Only works well for purifying low TDS-level water.

UF & Advantages & Disadvantages

In certain areas where the water is generally found to be less contaminated because of chemicals, UF purifiers can do a great job. It is because UF (Ultrafiltration) Water Purifiers use a combination of thin membranes present inside a hollow tube. As the water moves from one membrane to the other, the next membrane usually has smaller pores than the previous one.

Thus, this UltraFiltration technique can easily remove dirt, and other impurities such as viruses, bacteria, and other germs effectively. However, the membrane does allow the chemicals mixed in water to pass through, so it is only advisable to use where water is less contaminated with chemicals. Although the technique used by these purifiers is pretty old, it works against germs. However, since it cannot deal with chemicals, the hardness causing impurities do not get eliminated from the water.

Advantages:

  • Electricity is not needed to run such types of Water Purifiers.
  • Uses the simplest Purifying technique, by flowing the water through various filters.
  • Can easily deal with extremely dirty water, even cleans mud.
  • Germs and their dead bodies are completely taken out of the water.
  • UF membranes persist for a longer time, such as 3-5 years without getting damaged.

Disadvantages:

  • Manual cleaning of the membrane is needed.
  • Fails to remove hardness from water.

Gravity Based & Advantages & Disadvantages

Gravity-based Purifiers are the most affordable and easy to install products as compared to the other ones. As you can judge by its name only, it basically works using gravity, without needing any electricity connection or something.

The phenomenon is pretty simple for using these types of Water Purifiers. Generally, such purifiers consist of multiple filters in the upper section where all the visible dirt and impurities are eliminated as the water reaches the lower levels after filtration.

Once all the heavy particles and dust is removed, the water then passes through a section of an activated carbon filter that deals with all the remaining germs, parasites, and other impurities.

Advantages:

  • No need for Electricity.
  • Very Affordable.
  • Effectively removes germs and other microorganisms.
  • Highly Portable and can be placed anywhere as no running water is needed.

Disadvantages:

  • Struggles to remove hardness from the water.
  • Maintenance is high.

Multi Stage & Advantages & Disadvantages

Multi-stage Water Purifiers are highly recommended in those areas where water is generally hard and has other chemical contaminations too. The name multi-stage is given to this type because it uses various kinds of pre-filters, and thereafter, uses additional features such as UV treatment or adds alkaline chemicals to improve the quality of water.

The purification process is fairly long but effective at last. Although these kinds of Water Purifiers are one of the best and can deal with any kind of impure water, the overall design is usually very bulky that can seem hideous in a modern-kitchen.

Advantages:

  • Capable of removing 99% germs and impurities from water.
  • Maintenance is very low.
  • Easily removes hardness from the water

Disadvantages:

  • Design is usually hideous and bulky
  • Installation is complicated
  • Slightly Expensive

Based on all such facts about these different types of Water Purifiers, here’s a quick comparison table for you to revise them.

Conclusion

Depending on the quality of the water present in your region, you can pick any of the options as per your preference. However, if you ask for our opinion on the same, RO purifiers are a great option to go with since they are relatively cheaper and work well with all types of water.

Although if you have no issues regarding the budget, the Multi-Stage Purifiers do offer cleanest drinking water, and also do not waste much water like RO purifiers.On the other hand, if the water in your region is naturally clean, you can still choose a gravity-based Purifier to be extra sure since they are highly-affordable and work without electricity.
