Four things to keep in mind before purchasing a water purifier

Depending on the quality of your water source, a number of purification processes necessary to provide your household with the cleanest possible drinking and cooking water can be estimated. Many toxic sediments must be removed from the water before it is purified. Hence the procedure is multi-step. A water filter can come in various shapes and sizes, each with a specific function and set of specifications. They can remove inorganic compounds and the unpleasant smell of tainted water. Some filters that use activated carbon and sediment cartridges remove bad odour and sand but can not remove inorganic salts. Before making a purchase of a water purifier, here are four things to consider.

Quality of the water

Because most of the water in your house is hard, it has a high total dissolved solids (TDS) level. Inorganic salts such as calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulphates make up water’s total dissolved solids (TDS). An RO (reverse osmosis) system is the finest water purifier to remove these inorganic chemicals. The pore size of a RO membrane is .0005 micron, making it impossible for dissolved solids to be present in your drinking water after the purification process.

Contaminated water or soil

Water that has been tainted includes dangerous heavy metals, including arsenic, lead, arsenic, magnesium, copper, and iron, all of which should be avoided. These metals are found in water due to the rise of industrial and city infrastructure. Concerns about nitrate contamination are also warranted. This is a common occurrence because of agricultural practices. The dissolved and suspended pollutants are removed by reverse osmosis. Hence a RO system is recommended. Another water filter to consider is an ultraviolet (UV) disinfection filter. The hazardous germs cannot grow in a UV filter because of the UV lamp’s light.

An RO-based UV purifier is another option. Ultra-filtration (UF) can be used with a RO or UV filter to remove microorganisms from the water supply, which is ideal if TDS levels are low. RO systems that use cartridges containing minerals are also available for locations with high TDS levels.

The amount of pressure in the water

Depending on how much water enters the system, you need the type of filter. High water pressure is not a problem for a reverse osmosis system. Elevation of harmful chemicals and other variables like blocked pipes and clogged filters might affect the amount of water pressure in your home or business. Pressures ranging from 5 to 40 pounds per square inch are commonly required for water purifiers (psi). If the water pressure in your home is low, a RO system can be paired with a booster pump. If your water source has a low TDS, an activated carbon filter is another option.


Water purifiers can’t function without electricity. The ultraviolet radiation that kills bacteria is generated by an ultraviolet (UV) filter, which cannot function if electricity isn’t present. Without electricity, a RO system would not be able to deliver the RO membrane with the necessary water pressure. No energy is needed for activated carbon purifiers, such as sediment and ultra-filtration filters (UF). Some of the chemicals dissolved in water can be removed by RO and UV purification systems, while the non-electric purifiers only remove germs and sand from the water. Electric-powered water purifiers are the best option.
