In almost every kitchen in this present time, water filtration systems are a common fixture.  This is because many scientists and heath experts have warned on the pollutants found in our drinking water supply.  These pollutants are manmade found not just at home but in municipal systems, glaciers, rivers, lakes and wells.   It is known to come with its own issues that have severe health and environmental impacts. Installing a good water filtration system is the safest way to make sure that water is safe and drinkable.  This, however, doesn’t end at just installing filters.
PUR Water Filter differ as well as their costs and how effective they can be even though the overall purpose is for safe and quality drinkable water.  When thinking about kitchen renovation it is also of equal timing to think about the available choices in selecting filters.  For selecting the best water filter, some of the much-known filters are discussed below.

Reverse Osmosis

One of the best available filtration techniques in the present day is the reverse osmosis.  This is a very old process which has lasted for more than a century. It was only in the 1950s that the United States built it up as a system the Marines can use to make water drinkable by desalinating it.  Normal osmosis is when there is a movement of molecules through a membrane to balance the concentration of molecules on either side.  Reverse osmosis is the reverse of the normal osmosis process.  Rather than balancing the concentration of molecules on either side of the membrane, water pressure carries clean water one side of the membrane. On the other side, a concentration of pollutants is left. Reverse osmosis usually makes use of two carbon filters as well as other pre-filters that help to wipe contaminants.

Some of these contaminants are arsenic, mercury and lead.  By reverse osmosis, there is an effective removal of medications.  Some are MTBEs, THMs, viruses, VOCs, pesticides, herbicides, chloramines, fluoride, chlorine, percolate, coliform bacteria, E.coli and Cryptosporidium.  There are usual countertop or faucet filters classified as one stage filter because of their single basic carbon filter.  But in comparison, the reverse osmosis system offers a five-stage filtration system.  In addition, countertop filters contaminate less than one micron.  Thus insecticides and asbestos might not be filtered out.  This gives it a 1-5 micron rating. On the other hand, with reverse osmosis filter, it usually has a .0001 micron rating.  Though at the initial stage reverse osmosis can be quite more expensive, replacing the filter is done once in 12 months.  Replacing countertop filters, on the other hand, is done every few months.
Effective reverse osmosis gets rid of a striking collection of harmful contaminants. At the same time, it can also get rid of essential minerals that improve taste and health of the water.
