Getting fresh, healthy water is all about starting with the right water filter systems. If you’ve dabbled in a bit of research on water filters, you know that there are a few options that you can consider for your filtration methods such as filter pitcher, general carbon water filter, under sink water filters, countertop water filters. One of the most popular options is reverse osmosis. However, what is it, how does it work, and why should you consider it? Let’s have a closer look into the Reverse Osmosis Water Filtration Systems.

 

 

 What is reverse osmosis? 

 

Traditional osmosis is when water is absorbed along with its minerals, etc into, say, a plant. The keyword here is that it is absorbed. In contrast, reverse water is when water is forced through a membrane (pushed rather than absorbed willingly) so that it can be separated from its contaminants. Think of it as a strainer for your water source!

 

Defined by Wikipedia(2021), reverse osmosis is a typical water purification process that uses a RO membrane with extremely high filtration accuracy to separate undesired particles and elements as well as contaminants from water. Certain degree of pressure is needed to overcome osmotic pressure, normally driven by a embedded pump in the RO system. Therefore, most of RO systems requires a pressure tank and a powerful pump to trigger the RO effect. Electricity is thus needed.

 Why and how does a reverse osmosis system work? 

 

Reverse osmosis, in the case of water filtration, works by the water being forced or pushed across a membrane (the RO filter) that will push the water through it and strip away its contaminants, which are then disposed of through a drain. The clean and stripped water is collected in a holding tank to be used for drinking water, etc, as needed. Different from general activated carbon filters, it could eliminates almost all of the contaminants from raw water due to extremely high filtration accuracy.

 

Normally, a reverse osmosis membrane would have a relatively high price according to its capacity (50G ~ 800 G). There might be several stages of sediment filters or activated carbon filters before RO stage to filter out the larger particles from raw water so as to prolonged the service life of RO membrane. A/Several post filters might also be attached to RO membrane so as to polish the water taste of pure water or restore minerals back into pure water.

 

In order to work, the reverse osmosis filter needs to be installed in the right place with a general electric socket (not for garbage disposal one) and, of course, maintained regularly. Amongst the things to think about are the size of the filter, the price, the ease of installation and replacement, the psi requirements, even the flow rate (if you are a large family) and most importantly, the price of replacement filters. Since the RO water filter is for point of use, you’d hypothetically need a filter installed at the use point for every water source.

 Is it the right choice for me? 

There are a lot of perks to relying on a reverse osmosis filter for your home, which is part of why it’s such a popular choice for many home owners trying to do what they can to protect their loved ones with clean and healthy water. Some of them include:

    • ●Plenty of choice in products: There are all sorts of under counter and countertop reverse osmosis water filters out there that are going to give you the best selection of filtration options. It’s nice to have options when looking at prices, amongst other criteria such as size, ease of installation and working capacity, etc.

 

    • ●Simple, timely maintenance: Relatively simple when compared to other filtering systems, reverse osmosis filters are going to be simple to maintain, as well as give you the best cost effectiveness for their maintenance. Once being installed, normally it would require you to change once per 1-2 year.

 

    • ●Better water: Then there’s the fact that you’re getting better water quality, too. Different from ACF(activated carbon filter), the reverse osmosis water filter could generate water that is extremely close to pure. You’ll be able to have less contaminants in your water and it’ll taste great -- even better than bottled water that you purchase in the store! All for pennies a day.

 

Are there other water filtration options to consider? Yes, for sure, general water filters would be much budget friendly at first glance. However, between its breadth of options, cost-effective installation and maintenance, and most importantly, the overall water quality, you’ll find reverse osmosis water filters to be the leaders.
