Reverse osmosis filters :5 things to know before buying

Reverse osmosis filters :5 things to know before buying

Drinking water should be good for you. Unfortunately, this is not always the case, depending on where you get water.

There may be more than 2000 known pollutants in your drinking water. Some of the most common drinking water pollutants can cause incredible damage to your health. Including uranium and arsenic

This is worrying because nearly 77 million Americans violated the federal drinking water protection law in 2015.

If you drink tap water, use the water filtration system. Reverse osmosis filtration is the most powerful and reliable filtering technology you can find.

you need to know the following 5 things before purchasing the reverse osmosis water filter.

Learn 5 things before purchasing a RO filter

Reverse osmosis filters use a range of scientific principles to ensure that your drinking water is as safe as possible. It is a fascinating process when you understand its complexity.

we will help you understand how the reverse osmosis water system works.

What is osmotic action?

Have you ever heard of the word osmotic learning? might be used to justify someone sleeping in class or browsing the web in a speech?

Penetration is the process of transferring solvent from low concentration solution to high concentration solution. In this case, the solvent is water. water passes through the semi-permeable membrane between the two solutions.

this semi-permeable membrane can capture contaminants while allowing solvent passage. When the concentration of the two solutions is equal, the process ends. This process is called passive transportation because it does not require additional energy to work.

How does reverse osmosis work

Reverse osmosis requires energy consumption to move the solvent to reverse the permeation process. Apply pressure to move water from a high concentration solution to a low concentration solution.

Generally speaking, pollutant molecules are often larger than water molecules. Because of this fact, only water molecules can pass through semi-permeable membranes. The pressure of water allows water to pass through the reverse osmosis filter, leaving pollutants.

Reverse osmosis step

<unk1> The reverse osmosis filtration process consists of four main steps.


In the first stage of reverse osmosis, pressurized water passes through the particle filter. This can remove common pollutants such as sand, salt and sediment.

then, water passes through the activated carbon filter. This can remove finer contaminants such as mercury, copper, chlorine and pesticides. These are two steps in the pre-filtration phase.

Reverse osmosis

In the pre-filtration stage, water passes through the semi-permeable membrane. This membrane filters out the smallest particles, so only water can pass through.

Intuitively, the diameter of human hair is about 100 microns. in contrast, the space of the semi-permeable membrane is 1 micron wide.


The water was filtered and the pollutants were washed away. Then put the purified water into a storage container, which will provide clean water for your home.


Before returning the water to the faucet, go through the last filtration stage. It can improve the taste and quality of drinking water and other ordinary household water.

Common Reverse Osmosis System Composition

Although different manufacturers have their own unique designs, this is the basic template for most reverse osmosis water systems.

Cold water piping valve

Cold water pipe valves are connected to municipal cold water supply pipes. Connect the intake valve on the reverse osmosis filter as the water source of the reverse osmosis filter.

Automatic globe valve

Automatic globe valve helps reverse osmosis water system save water. When the tank is filled with water, it closes the globe valve and prevents more water from entering the membrane, thus preventing the production of water.

This can also prevent water from entering the sewer.

When pumping water from the tank, the water will reduce the pressure in the tank. This will open the automatic globe valve. In this way, water can be restored to storage tanks or discharged along the wastewater.

Check valve

The check valve is located at the outlet end of the reverse osmosis membrane cover. This prevents reverse flow or water from the reverse osmosis tank. this reflux destroys the reverse osmosis membrane.

Effectiveness of Reverse Osmosis Filter

Reverse osmosis water filter is almost foolproof. They can remove common pollutants from most drinking water.

In general, reverse osmosis can be effectively removed:

92-96% arsenic

95-98% barium

95-98% cadmium

94-98% calcium

85-92% chlorine

84-92% cyanide

85-92% fluorination

94-98% iron

95-98% Lead lead

Reverse osmosis systems need not be maintained

The water filtration system depends on its components. Other water filtration solutions, such as faucets or refrigerator filters, require continuous maintenance to ensure that they work properly.

Not to mention many commercial water filtration systems are not advanced enough to capture many common pollutants.

Reverse osmosis filters ensure that you and your family can drink the cleanest, safest, purest water in the next few years!

Are you ready to use the water filtration system at home?

Rest assured, this price is impossible! knowing that you and the people you love are becoming clean, pure drinking water can help you focus on the east so that you can focus on more important things.
