Reverse Osmosis Water Filter Reviews And Ratings

Two thirds of the earth’s surface is covered with water, yet we don’t have enough water to drink. Water is a very scarce commodity in so many places; it is almost unbelievable that so much amount of water is just lying there.

Well, the fact is that all that water in our oceans, seas, ponds and lakes is no good for drinking, because of the various things that it contains – dirt, chemicals and many other undesirable entities.

So why don’t we just filter it and make it fit for drinking? The process of doing that is not as easy as saying it out. Much of the stuff that is in that water is a result of days, weeks or maybe even months’ duration of contamination, and you cannot just remove those impurities from the water.

However, a process has been developed that can actually purify even the dirtiest of water, and make it fit for drinking. If you were to enquire about or watch a commercial that advertises water filters, you would probably hear the word “reverse osmosis enabled” over and over again.

Yes, this is the Reverse Osmosis Water Filter process we are talking about, that makes dirty water clean and fit for drinking and other purposes. Let’s see what reverse osmosis is about.

Osmosis Water Filter

What Is Reverse Osmosis?

First, though, you might be wondering why you need a reverse osmosis water filter in your house, when you receive pure drinking water, in stark contrast to the scenarios discussed above.

In that case, just get a sample of your drinking water tested at a lab, and be prepared to get surprised – the water you think is pure and clean is hardly that! All the traveling along pipes, the half efficient municipal filtering techniques and various other external factors make the water contaminated.

Although this impurity is only on a very small scale when compared to seas and oceans, a flaw is still a flaw, and you want nothing but the best for yourself, your kids and your family.

Reverse osmosis helps purify the water and make it absolutely perfect – it desalinates, recycles, treats and makes the final product the purest form of drinking water you can possibly find. How does this happen exactly? Do read on to find out.

The Reverse Osmosis Process

To find out what reverse osmosis is about, you first need to know about osmosis. Simply put, osmosis is the process of movement or diffusion of water from a low concentration solution to a high concentration solution, through a semi permeable membrane.

We will not get into highly technical details about this, so to illustrate in an easy way, just remember it this way – clean water (low concentration of dirty matter) mixes with dirty water (high concentration of dirty matter) through a semi permeable membrane (a partition that isn’t supposed to allow water through it, but it does) so that a balance in concentrations is achieved.

This mixture can take place anywhere while the water is traveling, so the exact location does not matter. What matters is the water that leaves the water treatment plant is not the same which comes out through your tap. It has undergone osmosis midway, and is not pure anymore.

By performing reverse osmosis, using a reverse osmosis water filter, a process just opposite to osmosis is simulated, and pure water is obtained. Again, to illustrate it simply, consider a solution of salty water to be purified by reverse osmosis. We put it in one tank, and have pure water in another adjoining tank, the two separated by a semi permeable membrane.

Now pressure is applied on the salt water solution, and as a result, water goes from this part and joins the fresh water in the next tank, leaving the salt particles in the first tank.

How does this happen? Since the size of the salt particles is too big to get into the membrane, they cannot travel to the other side under pressure, and thus only the water part goes, purified and free of salt and any other contaminants.

Benefits of a Reverse Osmosis Water Filter

By now you know what a reverse osmosis filtered water does to us, so here’s a small recap with a few additions: Reverse osmosis water is:

  • free of any impurities
  • safe for all types of people
  • does not cause any damage to the human body, it only has benefits
  • it tastes much better
  • it is healthy

Conclusion

It makes perfect sense to buy a reverse osmosis water filter. You can check out the various reverse osmosis water filtration system reviews available here, and make a choice for yourself, according to your needs and budget.

There are filters that can handle varying amounts of water for reverse osmosis per day, so choose according to your usage. Drink water that has been RO-ed, and stay healthy! By the way, RO stands for reverse osmosis.

Different types of water filtration

Water filtration is the water purification process to remove unwanted solids, microorganisms, gases and chemicals. The water passes through a medium that retains solids and allows water to pass through. It is important that you get a clean and purified water to prevent waterborne diseases. There are different types of water filtration. These include: ion exchange, distillation, filtration, ultrafiltration and reverse osmosis.

Distillation

In this method of water filtration, water is heated to boiling, where it vaporizes. The steam is condensed and stored after they were collected. It is beneficial because it eliminates a wide range of pollutants.

The main drawback of such filtering is that it can be other harmful chemicals that are sprayed with water and could be ingested by the assumption that water is purified. These are substances that may have the same point boiling water. Distillation also uses too much energy.

ultrafiltration

Ion Exchange

This process involves ion exchange. Water passes through the accounts as spherical resin materials. Water ions are exchanged with the ions attached to accounts. This method is commonly used for deionization and water softening. However, this method of filtration is most effective when used with other types of filtration, such as carbon filtration. Because eliminate many micro-organisms found in water.

Carbon sequestration

In this method, the water passes through carbon filters get rid of bad tastes, odors, chlorine gas, and many chemicals. Sometimes this method becomes rid of microorganisms. This type of filtration water will not affect the hardness of water, heavy metals and solids in the water absorbed. The water collected after filtration method can be improved by using another filtration method.

The ultra-filtration

In this mode of filtration, water passes through an ultrafilter which acts as a molecular sieve. It removes the dissolved molecules by size. It is beneficial in that it actually takes a lot of particles, microorganisms, and colloids above pyroids to its nominal size. It also provides high quality water and uses less energy.

Reverse Osmosis

Reverse osmosis as the name suggests, is the opposite of natural osmosis. Here the hydraulic pressure that is put to the concentrated solution to counteract the osmotic pressure. The purified water is collected in the bottom of the membrane. This type of water filtration products to be purified.

The collected water does not contain salts, sugars, ions and molecules that had dissolved prior to filtration. The filtered water Using this method is not acceptable that the filtered water has carbon. This method is advantageous because it requires maintenance least.

Ultraviolet radiation

This method of water filtration is mainly used to kill germs. Mercury lamps produce 254nm UV light is used. Microorganisms in the water are inactivated when DNA and proteins of cells to absorb ultra violet radiation.

We suggest that you must combine two or more filtration methods to improve water quality.
