Water Filter Replacement Cartridges - Why Are They So Important?

Have you ever wondered, what is the most important component for water purifiers? It is the water filter replacement cartridges. They are the driving force which is responsible for the basic performance of the filter.

If you search on the Internet, you will find a few purifier companies claiming that they do not use any water filter replacement cartridges. They even consider this as their USP! But the truth is that "no-replacement" is nothing better than "throw-away". Such filters become useless after some time.

The logic for using water filter replacement cartridges is simple.

A purifier has to face badly contaminated water daily - water which is polluted with lead, chlorine, pesticides, virus, cysts, drugs etc. An efficient filter removes all these impurities through various filtration techniques with the help of its cartridge.

Now, with time, depending upon the quality and quantity of water being filtered, the cartridge loses its efficiency. And hence the efficiency of the filter also drops by.

This usually happens once in six months.

Now while this may seem to be a serious problem to you, it is really not so. An easy way out to this problem is to replace the cartridge of the purifier. And your purifier is up again - performing as nice as ever.

The cost of the cartridge is something which should be considered while buying the purifier itself. Since it is a recurring cost, it is recommended to choose a system which comes with economically priced cartridges. In contrast, there are some purifiers which are available on a low onetime cost but their recurring cost goes up due to the high price of their cartridges. Steer clear from such systems.

Today market has multi stage purifiers which bring a combination of both - economically priced purifier as well as reasonably priced cartridge. These purifiers produce clean and pure water at something less than 10 cents per gallon!

An important thing related to cartridges is that they are designed based on the filtration technique that a purifier is going to use. What this implies is that it is tightly bound to the design of the purifier. So mix-and-match of cartridge and purifier i.e. using cheap cartridge coming from one manufacturer in high performing purifier coming from second manufacturer or other way round is not recommended.

It simply won't work that way. So, while selecting a purifier, take that extra care to check the cost and maintainability of water filter replacement cartridges as well.
