What makes people purchase water filters? 

Did you know that a water filter is different from a water purifier? 

Yes, you read that right. People use water filters synonymously with water purifiers, but they cannot be more wrong. While both water filters and water purifiers work on the principle of mechanical filtration, water purifiers eliminate more than dissolved inorganic material like microbes present in the water. To do this, purifiers use chemical or electrostatic methods of purification. 

Though chemicals like Chlorine tablets disinfect water up to a point, the presence of heavy metals like Lead, Arsenic, Mercury, and Cadmium, or the microbes in water cannot be treated effectively by them. That is the reason why there is an ever-increasing demand for water purifiers.

High-end water purifiers available in the market today are powered by more than one purification technology. The beauty of engineering is that these technologies work in tandem to produce clean water safe for consumption.

While the steps being taken to supply water to every household by the Government are a work in progress, the quality of water supplied varies from place to place. The total dissolved solids quotient is the measure of organic and inorganic matter dissolved in water. It is measured in parts per million and measured using a TDS meter. The principal constituents are usually calcium, magnesium, sodium, and potassium cations and carbonate, hydrogen carbonate, chloride, sulfate, and nitrate anions.

Water contamination is still a huge matter of concern for rural and urban communities in India. While the microbes can cause several water-borne diseases like typhoid, cholera, and dysentery, the heavy metals cause more insidious organ damage over a longer period of time.In order to combat this, consumers purchase a water purifier. 

An important thing to bear in mind is that a water purifier is a lot more than an engineering good or an electrical appliance. It is an investment, a cover so to speak, for your health and your family’s health. That is why we urge you to assess your needs carefully and purchase a purifier. The good ones usually last a decade. Those that are serviced on time can last even longer than that. So, make sure you purchase a water purifier that comes with a purifying technology or a combination of purifying technologies depending on the TDS levels of your water supply.

The ideal combination is that of a Reverse Osmosis module that works along with an Ultra-violet module. While the RO module eliminates more than 95% of the TDS present in the water, the UV module destroys 99% of the microorganisms present in water. The result? Ultra-pure water whose quality is not very different from that of distilled water.

However, those of you opting for this high-end water purifier should make sure that the unit checks a few other boxes. For instance, it should have a TDS modulator or a mineralizer cartridge that replenishes the water stream with useful minerals. It should have alerting mechanisms that alert you in time to take action. For instance, Pureit brand has purifiers with digital purity indicator that shows the purity levels of water throughout the day. Similarly, they are fitted with LED indicators to warn you about changing the filter fifteen days in advance. The Auto shut-off feature turns off the water supply in case the filter is not replaced. 

If your heart is set on an RO purifier, make sure that the water wastage is minimized. The Pureit RO water purifier comes with water-saving features that make it a better purifier when compared to its contemporaries.

If the turbidity of your water is low and your TDS is below 300 ppm, you can even try purchasing a UV water purifier. The Pureit UV water purifier has the following features:

 

1. The Pureit filter has a long life of 6000 liters when compared to the 3000-liter life of ordinary filters.

 

2. Lower maintenance cost that works out to just 25 paise per liter.

 

3. 4-liter storage tank that is ready to supply you output even in the absence of electricity.

 

4. Double purity lock with an advanced alert system that warns you 15 days before the purifier starts working.

 

5. The advanced fluctuation guard protects your purifier from voltage fluctuations between 110 and 270 volts.

 

6. Fully automatic tank filling where the purifier senses that a tank is not full and fills it automatically.

 

7. The UV lamp is designed to last typically for 10,000 working hours.

 

Those who are not having a high disposable income and possibly living in the rural neck of the city woods can also safeguard their drinking water by opting for a gravity-based water filter. A gravity-based water filter does not need electricity or even plumbing at home. The gravity-based purifier has two chambers, the upper chamber into which water is filled and the lower chamber into which purified water is collected. They use an activated carbon filter and an ultrafiltration membrane to separate these chambers. An activated carbon filter absorbs impurities that are present in water. The UF filter is a membrane made of hollow fibers, so when the water passes through it, the impurities stick to these fibers.
