How To Choose The Best Reverse Osmosis System

It is widely accepted that the Reverse Osmosis (RO) System is the best water filter to use today. But choosing the best among these is not as easy as it may seem. As we pointed out earlier, most RO looks alike and are for the same purpose. But when it comes to getting a purifier for your use you must know how to choose the best Reserve Osmosis System out there.

From the definition of Reverse Osmosis, we learnt about the filtering medium semi-permeable membrane. When it comes to Osmosis membrane the most popular one is the spinal wound.

They exist in two forms – the CTA (cellulose triacetate) and the TFC/TFM (Thin Film Composite or Thin Film Material).

CTA is chlorine tolerant but TFM/TFC is not. The latter, however, has a greater resistance to bacterial attack. Therefore in choosing an RO if the feed water is not chlorinated, it is best to use the TFC form of a membrane, but if the feed water is chlorinated, then CTA is what you should use.

You must note however that most Osmosis systems use TFC membrane, but having a carbon sift support.

The purification of water using ROS usually passes through several stages before passing as safe for consumption. There is first the pre-filtering, to remove large contaminants; the water then passes through a membrane made of TFC. The optional secondary pre-filter, the ultra-violet lamp and carbon post-filter, captures and removes all the chemical in the storage tank.

In choosing the best Reverse Osmosis System, look for the ones with 4 to 5 or more stages of filtration system that comes in counter-top, portable and/or fish tank filter.

What Makes A Best Reverse Osmosis System

It is important for you to know what components make a reverse osmosis system. This helps increase your knowledge about the device and help you in making choices.

  • Purification Stages:  The prominent use of ROS is in the purification of water. To ensure that water is 100% safe, it needs to pass through several stages of purification. The best reverse osmosis system must have up to 4 stages of purification and above. A Higher level of contamination requires more stages of filtration for better purification. However, the budget still plays a role here because the more feature that is in a system, the more expensive.
  • Filter Changing:  The reverse osmosis system should have a very minimal filter change. Quality filters should last a period of 6 to 12 months before changing it. Moreover changing the filters have to be super easy for the user.
  • NSF Certified:  To ensure that you get the best reverse osmosis system, the filter must have been tested and certified to meet the NSF standard.
  • Open Communication:  The producers of best reverse osmosis systems usually have an open lifetime phone/email customer support to assist the buyers all through. In Automatic Shut Off Valve:  The automatic shut off valve shuts the water tank immediately it is full. This is to avoid spillage.

  • Installation:  The reverse osmosis system must be easy to install in homes and offices. They usually come with a Do It Yourself videotapes along with the installation manual.
  • Low Consumption:  Since this system uses electricity, reverse osmosis systems usually have low energy consumption.

Things Need To Be Considered Before Buying Best Reverse Osmosis System

  • The quality Of Your Water:  Reverse Osmosis System functions to remove dissolved salts and impurities from water, including viruses, bacteria, organics, pyrogens and metals. You can only buy a ROS if the water in your area is infected with any of the listed contaminants or any other.
  • The quantity of your water supply: Before buying a reverse osmosis system, you must consider the amount of water supply you have. The RO system is known to waste as much as 2 gallons of water for every 1 gallon of clean and safe water you get. For that, you must have a constant water supply so as to sustain this system.
  • The quantity of clean water produced: Do you need clean, safe water for your home use or for a large number of staff in your office, firm or company. After considering these you now know if to buy an RO system and which type to buy.
  • Features: You may require an RO system with the usual basic features to produce clean, safe water for you, but some ROS with advanced features such as carbon filtration makes the water even safer and also removes any remaining contaminants including odour or taste. However, the feature you chose should be determined by the condition of your water supply. The dirtier the water, the more the need for a ROS with advanced features.
  • Budget Consideration:  This is no doubt one of the major factors to consider before buying a reverse osmosis system. Of course your budget according to your capacity to spend on your choice of ROS. If you are on a low budget, you need to carefully make a thorough research on the cheaper ones to be sure that they will serve your need.

Final Verdict

With this article, you must have been well informed what a reverse osmosis system is, the types, the features, uses, what to expect from an RO system and how to get the best reverse osmosis system in the market.

You have also learnt the basic considerations to make before buying your reverse osmosis system so as to be well prepared before making a purchase.
