Water is the most important element for sustaining life. The human body consists of two-thirds of water & access to clean drinking water is a human right. It is needed to keep you and your family healthy. Unfortunately, the supply of clean drinking water is not abundant, even in a modern city. A best reverse osmosis system or water filter system guarantees that you have access to clear & clean drinking water at all times.
The popularity of the system is mostly because of the undeniable cleanliness and purity that it provides to your home supply and really benefits the human body. But what makes a good reverse osmosis water filter system and what do the best reverse osmosis systems have in common?
Certain minerals and chemicals like excessive amounts of chlorine which are added to the water could pose harm to your body. Reverse osmosis process removes 95% to 99% of the impurities and produces tasty and healthy water. It is effective in getting rid of dissolved chemicals and heavy metals such as nitrates, sodium, fluoride, sulfides, giardia, mercury, arsenic, copper, radium and lead, Bacteria, Pesticides, Viruses and more. It can convert sea water into drinkable water at a fraction of the cost.
What is Reverse Osmosis (RO)
Reverse Osmosis is a process to separate liquids with different concentrations by applying pressure and passing it through a semipermeable membrane. The membrane separates the water with high concentrations of impurities from lower concentration. RO is also energy efficient as it doesn’t require any use of electricity. It only requires sufficient water pressure to power it through the entire process.
It removes metals, bacteria, chemicals and any contaminate greater than the size of a water molecule. Reverse Osmosis is one of the vastly used technique to filter water in the household and also in the industries, irrigation, and military. Reverse osmosis is one of the surest ways to purify clean water out there.
Our review guide will tell you what features to look for to find the best home reverse osmosis system. We will also provide you a list of the best reverse osmosis system.
What to Consider Before Purchasing the Best Reverse Osmosis System?
There are some important key aspects you need to consider when you are going to purchase an RO system.
We have listed below those key aspects to guide you through the decision-making process:
Brand, Manufacturer & Certificates:
When purchasing a reverse osmosis system, you should rely on an American recognized brand and a manufacturer based in the US. Because these US made RO systems can filter out at least 98 percent of water impurities.
You should also pay special attention to FDA (Food and Drug Administration) and NSF certificates. They ensure that the water processed by the system is of high quality. Furthermore, additional WQA (Gold Seal) certificates guarantee that a reverse osmosis filtration unit operates at low noise levels and requires only little to no maintenance.
The Filtration Process:
In a best RO system, the water usually runs through at least 5 filtration stages in the filtration process.
At first step, there is a sediment filter which removes soil particles and dust. Next one or two carbon filter removes chemicals, such as chlorine and fluoride, odors and tastes. The next stage involves the reverse osmosis process itself with a semipermeable membrane to filter out all remaining contaminants. Last but not least, a coconut shell refining filter removes residue taste.
Some of the expensive RO systems have additional processing stages to re-mineralize the water by adding bits of magnesium and calcium. It balances the pH-levels and create a great taste. You should always look for at least 5 stage Reverse Osmosis system water purifier.
System Installation and Filter Replacement:
An excellent water filtration unit will allow an easy installation and part adjustment without complications. Finding an easy replacement for any parts should be an easy task. You should seek for a reverse osmosis system with long-lasting filters that can be installed easily.
If you are looking for a great amount of water per day, you might want to look out for bigger membranes. They extend a unit’s longevity and shorten the time period that is needed to fill up the water tank.
Water Production Rate & Waste Rate:
The reverse osmosis system is by nature, quite a wasteful process. The early units would waste up to 20 gallons of water for every 1 gallon of clean drinking water. But things are better these days. Now it tends to waste around 2-5 gallons of water for every gallon of drinking water.
A best reverse osmosis system will prevent water from being wasted by automatically shutting down the system once the tank is filled completely. They will also provide a consistent flow of clean drinking water and it will help you to save money.
The water waste ratio can be reduced even further to around 1:1 with the addition of a pump to the RO water filter. The pump will also improve the water production rate of your system.
Best Reverse Osmosis System
Now that you have an idea of where to start, you would be looking to get the best RO system for the money. If you are going to find the best model, you have to consider the features it has to offer. Not all models are created the same. Find a model that you come with superior filtration features, compact construction, ease of installation and maintenance, and still affordable.
With the help of this guide, you should be in a position to make up your mind easily on the model to choose. We have chosen 7 best RO system for your convenience. Check them out
