Reverse Osmosis Water Filters

Reverse osmosis water filters are some of the most popular and preferred types of water filter nowadays. Due to its popularity, it is likely that even people considering water filters for the first time have already heard of the term.

But if you are considering purchasing reverse osmosis water filters, make sure you know all there is to know about the process and how they work before you make your purchase.

Understanding how these filters work will help you gauge whether a reverse osmosis filter is exactly what you need. Your knowledge of these filters may also come in handy as you use the filter so you can make the most out of it.

What Does a Reverse Osmosis Water Filter Really Do?

These filters became popular mainly due to the high level of effectiveness of this filtration method. In a nutshell, reverse osmosis filter hinders impurities from going along with water as the water passes through your pipes. It does so using a semi-permeable membrane that effectively remove contaminants from water that enters your household.

They are especially effective because it brings water through two stages of filtration. First, the water passes through a pre-filtering stage, which focuses on removing sediments that may have made their way to flowing water.

Finally, the water then passes through a post-filtering stage, using a post-filter in the form of the semi-permeable membrane, which makes sure any elements not filtered the pre-filter will not escape the filter anymore. The membrane has tiny holes that only water can pass through, so any particles, including really small bacteria, are left behind.

Reverse Osmosis: the Pros

The main advantage of a reverse osmosis system is that it is very thorough, with its two-step process, so you can be at ease that your water is perfectly cleaned. It removes most of the contaminants that can possibly affect the quality of your water.

It is especially effective against lead, calcium, chlorine, copper, pesticides, and most chemical substances. Other types of water filters may work against these substances, but if your water has nitrates, sulfates, and cysts, what you really need is a reverse osmosis filter system.

These filters are also easy to maintain because it can clean itself as the water flows back and forth during the filtration process.

Reverse Osmosis: the Cons

The first thing you have to know about reverse osmosis water filters is that they do not weed out carbons and other organic substances in water. Thus, it would be a good idea to use a carbon filter along with the pre-filter.

However, more important is the fact that they requires a lot of water during the filtration process, so it is not the most efficient water filtration method around. You will need more than a couple of gallons of water to produce a single gallon of pure and clean water.

You cannot reduce water usage since the excess water also helps clean the membrane. Reverse osmosis water filters are also not easy to install. Though most models come with DIY kits, installation may take hours especially if you are not familiar with the process.

This is why you will most likely find the need for a professional plumber. And finally, reverse osmosis are expectedly more expensive than the usual carbon block water filters and other types of filtration systems.

What the Experts Say

The process of Reverse osmosis has been certified by Center for Disease Control, which rated it as the best purification method for cleaning water free of most health-harming substances. This certification sure adds to your reasons to trust only reverse osmosis water filters.
