Rather valuable research has been made on the prices of drinking water filters. Unfortunately, most of people think that the more expensive an item is the higher its quality. The same tendency is observed with drinking water filters, but it's not always true. In fact the price of a drinking water filter depends on many factors.
Reverse osmosis is the most expensive among drinking water filters designed for home use. Usually, these filters are used in huge industries and public treatment facilities. Nevertheless, they prove to be efficient for the home usage as well.

The major function of water filters is desalination, but water won't be safe enough for drinking without additional steps. The most expensive drinking water filter systems cost about $420.00. They usually offer carbon filtration in combination with a micron filter and the system balancing mineral content and pH levels. The average cost of drinking water filters is up to $150. The major factor influencing the price is mark-up. Besides, purchasing the drinking water filter directly from the factory may save hundreds of dollars. In this way it's possible to buy a high-quality drinking water filter for less than $150. They're usually placed near the sink and they're more convenient and less likely to leak than the units screwed directly onto the faucet.
In order to extend the filter's life it's better to do dishes or wash vegetables in unfiltered water. In case of cooking though switch on the drinking water filter and enjoy tastier healthier foods! One may also find extremely low prices for drinking water filters that equals to about $40. At first finding such a filter you may think that it's an excellent suggestion for large families whose budget is limited, but later you may find a few problems about such cheap filters.
The matter is that a great number of cheap filters are just chlorine filters, not purifiers. And thus, numerous dangerous contaminants including THMs and VOCs, which may lead to cancer, won't be blocked by the cheap filters. Secondly, many cheaper filters contain toxic metal lead. Nowadays, lead contamination is one of the greatest problems in numerous cities. This situation happens not because the treatment facility is working badly, but because the pipes that running into the houses are extremely old.
Bacterial cysts are one more harmful contaminant of water that can't be effectively removed by a cheaper drinking water filter. These constituents may lead to parasitic infections in the gastrointestinal tract and may even kill little children, the elderly and people with a compromised immune system.
Finally, it's necessary to mention that cheap drinking water filters require more finances while being used - in average more than twenty cents per day in comparison with ten cents per day using an expensive filter. As you can see, an initial lower price doesn't mean further saving money, but spending more money on replacement filtration cartridges. Usually, cartridges of cheaper filters have a shorter lifespan.
