Everything To Know About Reverse Osmosis:

Reverse Osmosis systems are most famous nowadays because RO is considered the best water filtering solution. But does it work the same for all kinds of waters?

To understand how Reverse Osmosis Works, you need to read these first.

Osmosis is when water with low salt concentration moves to words high salt concentration area through a semipermeable membrane.

Let’s say you have two containers; one is filled with high salt concentration water and the other with low salt concentration water, and a semipermeable membrane separates both. After some time, you will notice that water with low amounts of salt decreases and water with high amounts of salt increases. 

And Reverse Osmosis is the process of Osmosis in reverse. In the system, you will see a RO membrane that makes everything happen. RO membranes allow clean water molecules through it but don’t allow salt, bacteria, organic matter, and acidic molecules to pass through it. 

In Reverse Osmosis, we apply pressure on water molecules which is more significant than naturally occurring osmotic pressure.

Generally, most of the RO membrane allows molecules to have a lower molecular weight lower than 200. This means that the RO membrane can filter a lot of micropollutants from water. In the efficiency section, we will deeply discuss the efficiency of RO systems

How ZeroWater Filters Work? 

ZeroWater filter is also the best solution to remove contaminants from water. These filters work differently from Reverse Osmosis systems. ZeroWater filters work on the principle of ion exchange technology which is very easy to understand. The Ion-exchange method is best to remove TDS and micro-level pollutants.  

How Does the Ion Exchange Method Work?

The ion exchange is a chemical reaction that swaps or exchanges all the harmful ions with good ones without affecting water quality.

It’s a reversible chemical reaction where all dissolved ions are replaced with other ions with the same electronic charge.

This reverse reaction takes place immediately and filters all the pollutants from the water. If you want to know more deeply about the Ion Exchange Method, visit here.

Zero Water Filter vs. Reverse Osmosis: Price

In the price department, there is a huge difference between both filtration methods. Reverse Osmosis is a pretty complex process, so it’s a pretty pricey way to filter your water. On the other hand, Zero water filters, pitchers, under-sinks are not expensive compared to RO. 

Zero Water Filter vs. Reverse Osmosis: Efficiency & Performance

What Does Zero Water Filter Remove?

Reverse Osmosis

In Reverse Osmosis, when water is passed through a 0.0001-micron membrane, it can filter all the pollutants nearly equal to 0.00000004 inches. So you can guess how efficient RO is. It only allows water molecules that are so small.

According to research, Reverse Osmosis can remove 99%+ of dissolved pollutants like salt, contaminants, particles, colloids, bacteria, viruses, pyrogen, etc. 

Now you might think RO is the best solution for hard water? Yes, RO systems are perfect for removing hardness from water. But after some time, hard impurities may clog the filter, so you must change the activated membrane after some time to ensure proper filtration.

If you are looking for the best solution to eliminate bacteria and viruses from water, reverse osmosis is ideal. It removes all the micro-level contaminants making your water 100% pure and healthy.

ZeroWater Filters

According to the manufacturer, the Zero Water filter system can remove 99% of dissolved pollutants from water. They claim their filter is twice as efficient as its main rival.

Zero Water filter is also tested on the water with excessive amounts of Zinc and chlorine, and it’s noticed that it can remove these impurities and improves water taste. 

To ensure excellent performance, all the Zero Water filters are tested under different NSF standards. For Example Zero Water filter pitcher is certified to reduce chlorine, lead, and chromium from water.

Thanks to its advanced filtration technology that removes 99.6% of TDS, it’s much better than Brita or any competing water filter. For removing TDS from the water, we strongly recommend a Zero Water filter.

Zero Water Filter vs Reverse Osmosis: Pros And Cons

Benefits Of Zero Water Filter:

Chlorine Removing:

Chlorine is a big enemy of taste; excessive amounts of chlorine in water ruins its taste. But Zero Water filters are the perfect solution for chlorine water. These filters are NSF certified to remove chlorine and all harmful heavy metals so that you can trust their performance. 

Reduce TDS Level To 0

The great thing that I love about the ZeroWater filter is its TDS removing power. No other water filter pitcher can compete with the Zero Water filter in terms of TDS removal.

It can eliminate 99.6% of TDS, removing almost every impurity to leave behind ultra-clean water. This is because of the five-stage filtration technology that Zero Water uses in its pitchers 

Portable Design

Because of the ergonomics design, you can easily hold the water filter pitchers and pour water into the cup. There are a lot of water filters available in the market, but the ZeroWater filter has its own identity and uniqueness. 

If you like a more convenient and lightweight pitcher, we recommend ZeroWater – 6 – Cup Pitcher, easily fitting into the refrigerator. 

Compared to RO systems, Zero Water filter systems can be easily installed, and they don’t require any serious maintenance. 

Disadvantages of Zero Water Filter 

Slow Flow Rate

Compared to other competing brands like Brita, BWT, Mavea, etc., Zero Water filter offers a slow water flow rate which may be its major disadvantage.

And after extended use filter clogged, and the water flow rate further decreased. So you have to change the filter after every 2 months to get a stable flow rate. 

12 Reasons Why Your Zero Water Filter Is So Slow? 

The filter lifespan is too short.

All Zero Water filter systems capture dirt and pollutants through an activated medium, which means you have to change the medium after some time. Change of medium depends on the water quality; if your water has excessive impurities, they will clog the filter sooner. 

But as compared to competitors, Zero Water filters have limited medium life in Spain. You need to change the filter medium after filtering 15 gallons of water. Whereas in the Brita system, you can change filters after filtering 40 gallons of water which is much better.

Also, Remove Useful Minerals

Zero Water filters reduce TDS level to 0. During this process, all other essential minerals are also removed. Naturally occurring minerals are beneficial for our body but Zero Water filter remove all these to achieve 0 TDS level. 

Benefits Of Reverse Osmosis System

Fast Filtration

RO systems offer a fast flow rate compared to Zero Water filters. You don’t need to worry about waiting, and this system immediately fills your cup with pure water. Most of the RO system comes with faucets that give fast flow rate, and you can easily take from faucet anytime.

Effectively Remove Bacteria

When it comes to removing bacteria, RO systems are a perfect choice. The RO membrane is capable of removing all the micro-level contaminants that are nearly equal to 0.00000004 inches. If you face any bacterial or viral infection, you should use the RO system to get germs-free water.

Other Advantages

  • The Maintenance of the RO system is easy
  • RO systems require little space as you can easily install them under a sink. 
  • They have a long lifespan.
  • RO systems are automated and are designed to start and stop on their own.

Disadvantage Of Reverse Osmosis Systems

Clogging Of Filter

If you live in an area where water is full of pollutants and hardness, it affects the RO membrane. Regular filtering of hard water will clogged the RO membrane, so you need to change the membrane after some time. 

Or sometimes low-quality membrane can clog the whole system, and the water flow rate becomes too slow. To ensure proper filtration and flow rate, you should change the membrane after some time. 

Expensive

As compared to ZeroWater filters, RO systems are costly. The price of an under sink water filter system with RO starts from $170 and goes to $500.
