Watts Premier RO-Pure 4-Stage vs WP5-50 Premier Five-Stage RO System

Water goes through a semi-permeable membrane in an RO filtration system.

Water treatment systems are used in tandem with water softeners to make the water from the tap a whole lot better especially when using hot water in the home. People use treated water for a lot of things. Basically, we use it at home for drinking, cleaning veggies, washing clothes and dishes, and watering plants among a host of other things. 

reverse osmosis system

A reverse osmosis system at home ensures that you get great tasting clean water right off the tap. Of course, no one wants to purchase just any sort of RO system you can find out there. In our search for the best water treatment system with reverse osmosis, we came up with three parameters that we can use to check each system that comes our way. These parameters include the quality of the output water, the amount of good water it produces, and how much waste water the system expels. Given those parameters, we can make a reasonable comparison between the Watts Premier RO-Pure 4-Stage Reverse Osmosis System and the Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System.

Main Points of Watts Premier 4-Stage Reverse Osmosis System

  • Watts Premier RO-Pure 4-Stage Reverse Osmosis System Multiple Filter Design

Looking at the specs provided by the manufacturer, we find the design to be quite impressive. There are filters that deal with contaminants and other stuff you don’t want in your water before the water actually gets to the reverse osmosis filtration unit. Other than that, there is also a post filter after the RO unit, which is actually a carbon filter. After all this filtration business, we simply had to taste the water from this water filter system – and the water tasted great.

  • Water Output

The Watts Premier RO-Pure 4-Stage Water Softener works much like any home water treatment system. It produces practically the same amount of good water and waste water as well. It’s pretty much spot on as any other RO unit producing around a 1:3 ratio of good water and waste water. In a nutshell, the Watts Premier RO-Pure 4-Stage Water System is

  • easy to install
  • has a four-stage filtration system
  • produces a relatively standard water output

Watts WP5-50 Premier Five-Stage System  Main Points

  • Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System Five Stage RO System

This Watts water filtration system uses a five-stage filtration system. According to its manufacturers, it can produce a continuous supply of water for the home. The unit comes with a storage tank just like any Watts water filter system you’ll find in the market. The water is pretty good – good enough even for a hydroponic garden. We basically have no complaints about the quality of the output from this unit.

  • Water Output

The amount of clean and drinkable water produced from this unit is good enough for an entire household. However, we think that it has the capacity to produce more if it is put to the test. The only drawback we found about this superb treatment system was that it produced a bit more waste water than what we expected. Other than that, we think it’s a great product. In short, the Watts WP5-50 Premier 5-Stage Water System is

  • easy to install
  • has a five-stage filtration system
  • makes enough water for an entire household

Final Verdict – Water Treatment Systems with Reverse Osmosis

Both of these reverse osmosis systems are quality products.  However, we feel that the Watts Premier RO-Pure 4-Stage Reverse Osmosis System is slightly better since it produces less waste water.
