Pros and Cons of a Reverse Osmosis Water Filter

Using a reverse osmosis water filter to ensure good, clean, healthy water for the household or working place requires that you have all the basic information necessary on how this system works and what it involves before buying and installing.

Reverse Osmosis in Brief Mode

The porous filter in the reserve osmosis system is mainly a contaminant remover; it is made up of very tiny pores through which the water flows, leaving behind bacteria and other toxic waste. It is also the perfect desalination system as it isolates salts and other natural minerals from the water. All impurities removed are then expelled down the drain.       

Drinking Water

To have safe drinking water, the system has to make use of a complementary carbon filter or ultra-violet light because pesticides and chlorine molecules, which are smaller than water molecules, pass easily from the porous filter. This porous filter unfortunately also removes all natural minerals like magnesium, calcium and potassium which are highly essential for the body. Water stripped of these essential minerals can be noxious to good health. Also the low alkaline content absorbs calcium and other minerals from the body thus depleting it completely from these important minerals.

Water Waste

Water scarcity is being felt all over the world and unfortunately a reverse osmosis system wastes a lot of water that runs through its system before producing purified water. The estimate is of 1:3 gallons of water, which means that 3 gallons of water go literally down the drain for every treated gallon produced. The process is also quite slow, producing not more than 15 gallons a day.

Reverse Osmosis for Other Uses

Bathing water which is free of contaminants helps skin and hair become softer and keep their natural moisture. It also eliminates skin irritations and removes almost all the lead content in untreated water which has affected many children in their cognitive abilities.

Food which is washed and cooked in reverse osmosis water has a better taste. Laundry is softer, colors are brighter and stains are more easily removed.

Things To Consider

You may install an under the sink system or you may install a whole house system; this depends mostly on your budget. If you have to add an ultraviolet light system for further purification this will increase the expense both for installing and for maintenance; every now and again filters have to be changed and the waste acidic water produced after filtration can play havoc on your pipes and plumbing system.                                                                                                                                                            

Take into consideration all the pros and cons before committing yourself and you might even consider looking up other purification systems such as a water softener system which might suit your needs better; you might also consider the suitability of the water condition in your area which will help you decide even better which system you do actually need.


When you have chosen the system you prefer leave it to the professionals to install and maintain, thus you will make sure that it is functioning as it should all year round.
