RO water filter should be avoided where not needed

First, try to  avoid using RO filter if water quality not needs it।for canal and deep bore supply generally not needed।

You can safely drink water upto 600 tds if not have harmful content 

If water tds is just 300 range, it is unlikely any contamination has gone into its source।water has salts of many minerals necessary for health like sodium calcium magnesium zinc etc required daily।

300 tds means you get enough minerals if you use 2 ltrs in drinking and cooking daily।

RO output is not healthy having 20 to 50 tds range only।  you should drink 150 to 500 range।

Ro water with 15 to 30 tds is called hungry water it same as battery water.

Not only it may absorb oxygen from tissues it lacks daily needs of minerals . Hence honble NGT has banned selling ro to those having upto 500 tds supply.

Dm water which has 5 ppm tds can eat into steel pipes.

Well RO has several filters starting with first paper or filament filter to check suspended dirt।

Then comes main filter RO Membrane that actually removes dissolved salts and harmful content including bacteria।If you have membrane dont need UV light also।

In fact life of membrane depends on amount of water cleaned and quality of incoming water।

Ensure your incoming water does not have high chlorine।

Normally life of 7000 ltrs or 2 years, is okay।

Dont change yearly if use is less like a couple using it।Suppliers will ask you to change yearly।

When membrane goes bad it will give metallic taste tds will rise high or too low।

It is very costly you will spend 10000 yearly on consumables maintenance power and get bad for health tasteless water ।

So first avoid RO use if not necessary and try to run 7000 ltrs or 2 years if not bad greasy high chlorine water coming in water supply।

For example a couple will use 7trs per day average or 2500 ltrs per year।

So why change filters in a year unless signs exist ?

Remineraling is costly and useless।

Tds controller hardly works। dont blindly follow smooth talks of salesman

Just use 2 filters plus uv tube

Remember it is all business to keep making money for 10 years at least।

New models with fancy names tds control , remineralise , herbal flavor।

None is feasible at ruling price and needed।

Like medicines and other machines use RO water filter if risk to health and huge costs and wastage of water is justified by saving of life and cleaning undrinkable dirty or high salt water like sea water
