Is it Good to Install RO Purifier?

Reverse osmosis is the only process that purifies drinking water which is not safe for consumption.
RO water purifiers with a TDS controller is an ideal way to get pure and healthy water with essential minerals in it. Few things you need to check in term of water quality and purifier component quality:

  1. First, check your water quality in terms of the TDS level.
  2. Purifier parts or filtration level quality – Never install aluminum UV filter. Always prefer good quality stainless steel ultraviolet filter in your water purifier system.


Check your tap water quality in term of TDS level:

If the water supplied to your home is high in TDS (more than 500 ppm), hardness and salinity then RO is the best choice for your home. But installing a cheap RO system may be hazardous because of quality compromise infiltration parts. RO has a semi-permeable membrane that has a pore size of .ooo5 microns. Such tiny pores can remove the tiniest of dissolved salt, metals, and impurities.

For areas where home tap water is soft and has TDS under the permissible limit, ultrafiltration (UF) or gravity-based purifier, and carbon activated filters can work well.

If you are installing RO water system, make sure you really need an RO water purifier by getting the TDS Level checked. TDS level indicator and controller are mandatory if you are installing RO purifier.

What is the function of a TDS level Controller?

TDS controller is a device present in RO water purifiers that adjust the TDS level in the water. A TDS Controller, just like the name suggests, helps in controlling the level of Total Dissolved Salts (TDS) present in water.

Is it Good to Install RO Purifier? – TDS Level in Drinking Water – Acceptable & Unacceptable

TDS Level in Drinking Water – Acceptable & Unacceptable

TDS (ppm) Remarks
Less than 50 Unacceptable because of a lack of important minerals
50 – 150 Acceptable for Drinking
150 – 350 Good – Acceptable for Drinking (Healthiest in regard to cardiovascular health.)
350 – 500 Fair
Greater than 500 Unacceptable for Drinking

Different government has different recommendations for the TDS level. According to WHO, TDS level as follows:

  • Excellent, less than 300 mg/litre;
  • Good, between 300 and 600 mg/litre;
  • Fair, between 600 and 900 mg/litre;
  • Poor, between 900 and 1200 mg/litre;
  • Unacceptable, greater than 1200 mg/litre.

It is recommended that people with kidney problems should drink pure water having a TDS level below 100 mg/L. It will help them recover from their health situation. Water with a very low concentration of TDS is also not acceptable for human consumption.

How to Measure the TDS level of your tap and filter water?

You can measure the TDS level in two methods at your home.

Method 1 – You can use a Digital TDS Meter. You need to buy this meter that may cost around 10USD.

Method 2 – You can use filter paper and a scale. (Easy & economic for home).

NoteNever install RO purifier in soft water, install only when you have saltine water having TDS more than 500 ppm.

Other Investigations:

Scientific research in the New York Times, for instance, found that American tap water contributes to rashes and skin burns, erodes tooth enamel, and often contains lead, arsenic, barium, and other toxic chemicals and bacterias.

An Associated Press investigation found numerous contaminants in every state’s school water. Data from the Environmental Protection Agency (EPA) revealed 1 out of every 5 schools investigated violated the Safe Drinking Water Act during the past decade.
