10 Best RO Water Purifiers [RO Water Filters] To Buy In 2023

So, you are in the market for the best RO water purifier. Let’s help you choose well with a detailed list of top 10 brand recommendations, alongside other useful information.

An RO purifier is more than a luxury. It’s, rather, existentially useful. Per WHO, contaminated water accounts for over 80 percent of diseases and 50 percent of child deaths globally. Think Hepatitis A, Malaria, Typhoid, Cholera, Amoebic Dysentery, and the list of waterborne diseases goes on.

Wondering how an RO water purifier can help? Well, to comprehend that, you need to know what RO is. Read on, as we walk you through the nitty-gritty of RO, from history to applications and more.

What is RO technology in the best RO water purifier? 

Well, RO stands for Reverse Osmosis. Herein, the contaminated water is bombarded on a semi-permeable membrane at high pressure. The pores of the membrane are just wide enough to allow the entry of water molecules while restricting that of the contaminants. Simply put, the pure water passes through the membrane, and the dissolved solutes are held back and eliminated.

Although Jean-Antoine Nollet discovered the osmosis phenomenon in 1748, it took the University of California to apply osmosis to desalinate seawater in 1950 for the first time. However, it was only with the improvements in the membrane that RO became commercially viable. Come 1977, Cape Coral adopted the technology for filtration at scale, becoming the first municipality to do so.

Wondering why they call it reverse osmosis? Well, the answer lies in the concentration gradient. In osmosis, the water molecules go with the concentration gradient while in reverse osmosis, they go against it. Guess what? Osmosis is a natural process associated with the movement of water within plants and animals. Rather, they rely on the phenomenon to achieve homeostasis.

How does the Best RO Water Purifier work?

The best RO water purifier forces water through a thin-film composite membrane. However, brands incorporate multiple filters to increase effectiveness and draw attention. Specifications may vary, but any decent RO purifier features the following steps, not in the same order though.

  1. Sediment Filter 1: Captures heavy pollutants, such as rust
  2. Sediment Filter 2: With smaller pores, it traps medium-sized pollutants
  3. Activated Carbon Filter: It eliminates chlorine and other chemicals that impart odor.
  4. Ultraviolet Lamp: The chamber exposes water to UV radiations to eliminate microbes.
  5. RO Membrane: Reverse osmosis happens here, getting rid of any impurities left in the water.

Mind you, certain steps are optional, meaning they might not feature in a standard RO purifier system. Also, some brands prefer cellulose triacetate (CTA)r the Sediment Filter 2 to prevent bacterial growth. Obviously, the prices tendtendincrease with the number of filtration steps. Some even have a mechanism to add minerals in water that are eliminated during reverse osmosis.

Why does the best RO water purifier matters? 

With nitty-gritty of reverse osmosis out of the way, it’s time to know why an RO purifier matters.

  • Complete Filtration: No other filtration system can match RO technology when it comes to effectiveness. It can eliminate almost all types of contaminants, from pesticides, viruses, and bacteria to fluorides and other heavy metals. On the other hand, water pitchers and filtration bottles feature filters made up of granular activated carbon. The filter soaks up contaminants that give water a bad taste or odor but is ineffective against disease-causing microbes.
  • A feasible option: The municipal water supply and underground water are both polluted. You cannot trust them for your and your loved one’s health. Likewise, packaged mineral water is not an option due to a variety of variables, such as availability and cost. On the other hand, portable reverse osmosis systems are ideal for home use, whether it’s tap water or fresh water from streams and rivers. Expensive though, they are a one-time investment for all filtration needs.

However, choosing a proper filter will be influenced by your budget and water purification requirements.

We have rounded up the top 10 purifiers from the best water purifier brands. Let’s explore their features:
