7 parameters to consider before buying a water purifier

Water is a basic necessity for sustenance of life. But today, the consumption of water from natural sources has become a question due to the widespread pollution. Another danger is the increase in the number of water-borne diseases, which increases the need to consume water that is purified.

So the demand for water purifiers has dramatically increased in the past few years, and the market is filled with different types of water purifiers. With different types available today, the consumer needs to consider 7 parameters before investing in a water purifier that is discussed below.

Water Quality

The quality of water at home should be evaluated first before deciding to install the kind of water purifier system. In some areas, the water is loaded with sediments, while in other places, the water has a high amount of pathogens. The odor and taste of water can detect the dissolved impurities that are present.

If the water has heavy sediments, then RO is a good choice because it comes with a semi-permeable membrane of pore size 0.0005 microns.

Daily Usage and budget

The average daily consumption of water in the family should be analyzed. One must decide whether the purified water is needed only for drinking purposes or for the Usage of the entire household, and choose a model accordingly. Ideally, the water from the water purifier for one hour cannot be less than the number of persons in the household.

It is necessary to decide the amount of investment in a water purifier. For UV-UF purifiers, good models are available under 12K, and for RO systems, there are models under 16K.

Purification process & Technology

A good way to choose a good water purifier among the many brands present is to compare the purification technology employed. This ultimately affects the water’s quality. To filter the contaminated water, every water purifier has some mechanisms. In RO systems, a semi-permeable membrane is employed, and in UV water filters, ultraviolet rays are used to kill the pathogens. Another type is the UF that uses hydrostatic pressure to remove the bacteria and viruses from water.


The RO and UV water purifier types require electricity to function. So, if the residence is in an area with insufficient power supply, it is good to invest in alternate water purifiers that can cope with the power shortages.

Maintenance Cost

All water purifiers will require regular maintenance at an interval of 3 to 4 months, and the filters are required to be changed yearly. The cost of maintenance can vary from 2K to 5K, depending on the models. So it is wise to consider the cost before investing in a water purifier.

Buy registered product

Since there are numerous companies that market water purifiers, it is mandatory to check for the registration of the appliance before buying. Some companies sell water purifiers of cheap quality with no quality check. Make sure to buy water purifiers only from registered franchises.


Based on the level of contamination, it is advisable to select a water purifier to address that issue. For killing pathogens, a UV water filter is a good choice, and for removing salts, an RO system will do the job.

The wellness of the family is entirely dependent on good water purification technology. It is necessary to collect details about the product and invest in a water purifier system that meets the family needs.
