4 factors to think about before buying a water purifier

1. Water Quality

Mostly the water supplied to your house is water which means your home water features a high amount of TDS. Total dissolved solids in water contain inorganic salts like calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates. the simplest water purifier to urge obviate these inorganic compounds is an RO (reverse-osmosis) system. An RO membrane’s pore size is .0005 micron and makes it impossible for the dissolved solids to exist in your beverage .

2. Contamination

Contaminated water contains heavy metals like lead, arsenic, magnesium, copper and iron, and that they are often toxic if taken in large amounts. thanks to the rise of factories and growth of city infrastructure, these metals are found more in abundance in water. Nitrate contamination is additionally a cause for nice concern. Not only is it a results of agricultural processes but also where fishes generally live. In reverse osmosis, the dissolved and suspended impurities get reduced hence, it's advisable to urge an RO system. another quite filter you'll check out is an ultraviolet (UV) filter where the water gets disinfected. during a UV filter the harmful microorganisms cannot multiply with the radiation from the UV lamp. you'll also search for an RO based UV purifier. There also are some RO systems with mineral cartridges for areas with high TDS content.

3. Water Pressure

The incoming water system flow determines which filter you ought to get. Water pressure depends on the elevation of your building and other factors like blocked pipes and clogged filters. Water purifiers generally need a pressure of 5-40 pounds per sq in (psi). A booster pump also can be attached with an RO system if the water system in your home has less water pressure. Otherwise, you'll choose an activated charcoal purifier if your water system has less TDS.

4. Electricity

Electricity plays an important role when it involves water purifiers. Many don't work without electricity and that they are useful for homes with bad power shortages. An ultraviolet (UV) filter wouldn't work if there's no electricity, because it uses electricity to supply ultraviolet that eliminates bacteria. An RO system wouldn't work without electricity because it uses electrical power to supply enough water pressure for the RO membrane. activated charcoal purifiers don’t require electricity a bit like sediment filters and ultra-filters (UF). While RO and UV systems remove TDS and bacteria that cause water borne diseases, the non-electric purifiers can only get obviate a number of the chemicals dissolved in water, along side germs and sand. it's advisable to choose water purifiers that run on electricity.
