The Best Reverse Osmosis System Guide For DUMMIES

The world is full of so many different types of water filters. You can get a basic water pitcher jug that simply filters out water contaminants with a carbon filter. This is enough to make water smell and taste good. However, if you want and need complete and total water filtration then you really can’t beat getting the best reverse osmosis system.

You don’t need to fork out a small fortune for a whole house reverse osmosis system. You can simply get an RO filter that attaches to your tap faucet. It will easily fit under your sink along with all the plumbing and that’s it. Just leave it to filter and it will remove all contaminants from your water.

Reverse osmosis is one of the easiest ways to get clean filtered water plumbing into your home. It is very efficient and doesn’t create too much waste and this is why RO is the filtration method of choice for industrial processes.

Let’s take a closer look at the best reverse osmosis water filter systems currently available on the market.

Why Is Reverse Osmosis Water Good For You?

Reverse osmosis is one of the most popular systems for filtering and purifying water. 

The reverse osmosis system is very efficiently able to remove and filter contaminants from water. It is able to radically improve both the quality and taste of your water. But it is also powerful enough to remove minerals from things like saltwater.

Aside from making sea water drinkable, it removes all manner of contaminants. For instance, a variety of contaminants like bacteria, herbicides, lead and other heavy metals.

These types of contaminants dissolve very quickly in water so are hard for other methods of filtration to remove. But unlike the others, RO is better able to handle fully dissolved pollutants.

Idea IconHow To Get The Best Reverse Osmosis System

Getting the best reverse osmosis system means that you will efficiently and quickly purify the water in your home.

Sadly, not all RO systems are built the same. If you are considering purchasing a unit then there are a few things you should consider:

1. Know What Size Filter You Need.

The best reverse osmosis system can come in almost any shape or size. You can get it in a single water filter faucet right up to a whole house filter. However, if you are only worried about improving the quality of your drinking water then getting a single faucet filter is probably enough. On one hand, you might have issues with the quality of water in your whole house. Perhaps you’re finding dirty water in your shower and bathroom sink? If this is the case, then you should get a whole house RO unit.

2. Do You Know What You Want Reverse Osmosis To Remove?

The quality of water is different from one place to another. And there are some places that suffer from high levels of contaminants in water.

Tell the water company to send you details about your water supply. If your water is supplied from a municipal source then you can contact them to find out all the information about what is in your water. They have a legal obligation to fulfill this request and getting the information is usually free.

Alternatively, you can buy a test online that will tell you all the contaminants you have in your water – in a matter of minutes.

Once you know what you’re dealing with, find the best reverse osmosis system that can adequately deal with everything on your list.

It might also be worth testing all the water that comes into your home. The water pipes that take water into your kitchen might be fine but maybe the pipes in your bathroom are corrosive? Leaching lead into your water supply?!?

The only way to know for sure is to test the water that comes from every faucet in your home. This might seem like a lot of hassle but if you find that all the water in your home is perfect except from one source, then you only need to buy a faucet filter. So, checking all the taps is annoying but it could end up saving you money in the long run.

Is Reverse Osmosis Water Good?

Healthwise the reverse osmosis process removes 92-99% of beneficial calcium and magnesium. However, most of the systems mentioned below “re-mineralize” i.e. they add healthy minerals back into the water.

Here are some other issues you might find with RO:

  • Reverse osmosis is one of the most efficient methods for purifying water however, it is not the fastest.
  • Be aware that the RO system can take some time, unless you have something like a faucet filter, which will produce water on-demand.
  • RO will often need a storage tank to store water that has been filtered (this is in the case of a whole house reverse osmosis water filter.)
  • The size of your whole house reverse osmosis tank will determine how much filtered water your home will have access to at that moment in time.

cost symbol Reverse Osmosis System Cost

It is possible to get a good basic reverse osmosis unit for $150-$300 and an extra $100-$200 for replacing filters each year. This makes it one of the cheaper forms of water filtration.

The main thing that causes a difference in price is the features that the includes and if it can cope with a larger capacity.

This is because most reverse osmosis systems do more or less the same thing when it comes to how they filter water and what they are able to remove. However, if you want a faster, more efficient system that will supply water to a larger home – this will cost you more.

Also note that some RO water filters also include other types of filters like solid carbon absorption or activated charcoal filters. You can expect to pay more money if you have a system that includes multiple forms of filtration.

Important Technical Issues To Consider Before Getting An RO System

One of the most important things to consider when selecting your reverse osmosis system is water flow.

RO filter units can sometimes require a minimum water flow rate and pressure to do its job properly.

If your home does not have a water supply that meets its minimum requirement then you may need a water pump to boost the water pressure for the RO unit to work properly.

If you have this issue, make sure you choose a filter that already comes with a water pressure booster pump. This will probably increase the cost but at least you can still use this water filtration system in your home.

Remember that reverse osmosis removes everything from your water. This includes things like the many minerals that can be good for your health.

The Benefits Of Getting An RO System

The biggest advantage of getting a reverse osmosis filter system in your home is that it can filter a greater amount of contaminants than almost any of the others.

This combined with its inherent high efficiency gives you something that is both very powerful and capable of providing you with the highest quality of filtered water.

  • Reverse osmosis systems usually create several gallons of wastewater to filter. However, the APEC RO system uses 3 gallons to make 1 gallon of filtered water. This is pretty low when compared to the others.
