Does Reverse Osmosis Really Work?

Ever heard a friend praising reverse osmosis systems? That they help get rid of contaminants from the water, making it safe, clean, pure, and healthy to drink, but you doubt it?

Or, perhaps you have concerns about water quality in your home and are interested in investing in a reverse osmosis system.

Actually, some people even claim that reverse osmosis is the most effective and economical method to purify water.

In this post, you’ll find out how the system works as well as its benefits. Reading through will help you clear your doubts on whether reverse osmosis really works or not, so stick around.

Reverse Osmosis and How it Works

Reverse osmosis is a water filtration method used to remove contaminants from water when pressure forces the water through a semi-permeable membrane.

Water flows from the side with more contaminants (more concentrated side) of the RO membrane to the side with fewer contaminants(less concentrated side) to provide clean drinking water.

Reverse osmosis is a refined method of water filtration, which can improve water quality and taste. It can significantly reduce dangerous impurities from your water and ensure that you get a constant supply of clean, pure drinking water at all times.

So, how does RO work?

First, pressurized water passes through a sediment filter that removes larger particles like sand, silt, and sediment.

After that, the water passes through an activated carbon filter that removes contaminants and minerals like mercury, chlorine, copper, and pesticides. The first 2 phases are referred to as the pre-filtration stage.

After pre-filtration, the water gets forced through a semi-permeable membrane where the smallest particles get trapped. Only water passes through.

Finally, all contaminants go to the drain in the discharge stage while the treated water gets into the storage tank.

And before it reaches the faucet, the water undergoes the final activated-carbon filtration that helps improve the taste of the water.

Benefits of Reverse Osmosis

Does Reverse Osmosis Really Work

Reverse osmosis offers several benefits for your home. Listed below are the positive impacts it can have on you and your household.

1. Produces Cleaner and Safer Water

Reverse osmosis removes the most contaminants from water. In fact, it stands out from the water filtration systems pack. It’s for this reason that the Environmental Protection Agency (EPA) cites it as one of the most effective in eliminating disease-causing organisms and chemical contaminants.

And did you know that some contaminants can make your water have a nasty smell? Some make it taste bad, and others can harm your health over time.

Reverse osmosis reduces your exposure to contaminants by removing viruses, bacteria, mercury, lead, arsenic, asbestos and other impurities from the water.

2. Improves the taste of your water

If you always host parties at your home, you know that the most important thing is great food and drinks for your guests, right? And you also know that purchasing single-use water bottles is quite expensive.

Installing an RO system in your home ensures that you can offer your guests quality water every time. And not just that, your family is also assured of great-tasting water.

And with tasty water, everyone will slowly start doing away with soft drinks like sodas.

3. Reduces the Need for Bottled  Water

Although most people purchase bottled water since it’s a quick way to get filtered water, it’s not the best. Bottled water is expensive and has negative impacts (because of the water bottles) on the environment.

With an RO system, you’ll receive an endless supply of pure water on demand, decrease your utilization of plastic bottles. It’ll also help you reduce your carbon footprint.

4. Easy to Maintain

Reverse osmosis systems are very easy to maintain. You only need to replace the filters when necessary, which is usually after every 6 months.

Whether you have an under sink, countertop, or whole house filtration system, all you need to know is the time to replace the filters.

So, Does Reverse Osmosis Really Work?

Manufacturers of reverse osmosis systems provide strong support for their effectiveness. Visit Amazon, and you’ll come across lots of very positive reviews on these units, which proves that they do work.

Reverse osmosis is also a proven technology to produce pure water that is not only suitable for drinking but also suitable for many industrial applications that require deionized water.

Water filtered by reverse osmosis is clean, pure, and healthy. It also tastes great, is free of odor, and helps minimize risks associated with taking water with potentially harmful contaminants.

RO is currently the only water treatment system that can remove most contaminants that are difficult to remove by other methods, including arsenic, fluoride, lead, pesticides, among others.

Thanks to reverse osmosis, you won’t have to worry about ingesting harmful inorganic minerals.
