FAQ Regarding Reverse Osmosis in Montreal

Basic reverse osmosis facts

  • Is an effective and thorough method of filtering water
  • Filters water through a semi-permeable membrane
  • Removes 95-99% of all dissolved solids including minerals and chemicals

Do I need to have reverse osmosis?

Yes, if you are located in an area where your water source is from a well, spring, river or any other source not using an officially treated water process.


Note: additional steps may be necessary such as UV light for disinfection of microbes.

How does reverse osmosis work?

A reverse osmosis (RO) system filters your water through a semi-permeable membrane where it removes all total dissolved solids.


It allows 5 to 15 % of the water to pass into your holding tank and flushes out the balance.


The filtered water you drink is taken from this holding tank.

Advantages of RO systems

  • This system takes out 99% of total dissolved solids leaving water without any minerals or chemicals
  • RO water will not produce scale in kettles and coffee makers

Disadvantages of RO systems

  • Eliminates 85 percent of the incoming water
  • Reverse osmosis systems are priced higher than carbon filtration systems
  • Produces water at a much slower rate than Jonli Water Services Inc's other carbon water filters
  • Removes all calcium‚ magnesium and potassium: good minerals required to aid in optimum health

Maintenance requirements

  • Change of the 3 filters once a year
  • Change of the reverse osmosis (RO) membrane every three years
  • Sanitization of the holding tank yearly

What if someone wants to test my water?

Often companies will market their reverse osmosis (RO) systems by using a demonstration that measures the TDS (total dissolved solids).


The TDS Test measures the total of dissolved minerals in the water‚ primarily calcium, sodium and magnesium‚ and has little or nothing to do with contaminant levels.


If you are unsure of the quality or safety of your drinking water, have it officially tested by a laboratory.
