What Is The Best Way To Filter Water

Author: No Comments Share:

Filtering water is the only way by which you can make impure water safe for drinking. There are many ways for whole house water filtration. Here are some of them and why some are better than the other ones.

Activated Carbon Filter

Activated charcoal or carbon is not something new that is used for cleaning and filtration. It has been used for centuries for cleaning the face and it was also used as a traditional toothpaste in the older times as well. Activated carbon filters are great for removing most of the impurities in the water. Carbon is like a magnet and all of these impurities are drawn to it.

Carbon absorbs these impurities in itself and you are left with clean and clear water, which is safe for drinking and use for dishwashing, laundry, and swimming pools.


Deionization is different from the normal ion exchange process because, in deionization, the heavy metal ions are completely removed from the water. Salts have a positive and negative charge and certain chemicals are added in order to attract the salt ions which are unwanted in water and those chemicals can be easily removed from the water, once the process is done.

This was first an industrial procedure for getting clean water, but now it is also used in houses and other commercial places.


Water distillation is the process of condensing the steam which is produced when water is boiled. This process also gives 99 to almost 100% pure water, but the distilled water amount is nowhere near the same as the amount of water being boiled.

For every 1 cup of water you boil, you will only get a quarter of a cup if not less amount of distilled water. This is very impractical and unless you are doing this on a very large scale, it’s not worth it. It also takes a lot of time to distill water.

Reverse Osmosis

You might have heard of reverse osmosis in science class. It is a very effective process and it is used for cleaning water all over the world. It is considered one of the best ways of filtering water and the water obtained by reverse osmosis is almost 99% clean.

A reverse osmosis filter consists of a semi-permeable membrane. It allows the small water molecules to pass through it but larger particles like dirt and dust are left behind. It also filters out most of the harmful chemicals and toxins in the water. It is a great way to get pure and clean water, but it is an expensive investment, so you need to make sure that you are purifying water on a larger scale to its money’s worth.

Ion Exchange Method

The ion exchange method is done to purify water which is extremely hard and has a lot of heavy salts and metals in it. It is treated with certain chemicals which will exchange the heavy metal ions in the water with other neutral ions in the chemical being added to the water. It is an effective way to clean water and filter it, but it does leave some residue at the bottom of the water, so you need to throw that part out, once you reach the end.

Ozone Filters

Think of ozone as a disinfectant. It is a newer technology for purifying water, but it is a great addition to water because it kills the most known microorganisms in water. It is great for people who are sensitive to dirty water and are prone to getting bad stomach sickness because of water.

Ozone is usually added to water and from here, it destroys all of the bad bacteria and other microorganisms in the water. It is also inert when it goes into the body, so you don’t need to worry about being sick because of ozone. It is also odorless and tasteless.


There you have it! Not only do you know the types of water filters you can use to purify water, but you also know which one is better and more efficient. You can now easily decide which one you want to go for. Some water filtration systems Warren are for the whole house while some are only for one tap. The latter is much cheaper.
