Each main type of filter system has its advantages and disadvantages. The question is, how do you choose the system that is right for you? This article will help you to make your choice.
The simplest and most convenient system is a "pitcher" system, which uses a pitcher, or jug or carafe or whatever you prefer to call it, with a built in filter cartridge. All you have to do is fill it up, and wait for the water to come through the filter cartridge. These systems are particularly useful for people who live in apartments or rented accommodation, who are prevented from making any changes or installations to the property. They also tend to be the choice of home owmers who are not inclined to do any installation work in the kitchen. They have the disadvantages that sometimes they can be quite slow in filtering the water, and also the cartridges may need to be changed often, about once a month is typical. It is worth checking on this before you buy one.
The second type of system is the "faucet mounted" system, sometimes called a countertop system. These are fitted to the faucet outlet, and they usually have an option of choosing either filtered water ot water straight from the tap, unfiltered, by turning over a lever. These are often the choice of those who do not want to do a lot of installation work. Most people can install them easily in a short time. They are quite moderately priced, and they work faster in general than pitcher systems. However, here again, the cartridges may need to be replaced quite frequently, and some people do not like the look of an appliance fixed to the tap.
The next type is the "undersink" filter, which as its name suggests, fits on to the supply line under the sink. The main advantage of this arrangement is that it is out of sight. The cartridges for this type of filtration system tend to be more long lasting. The undersink systems produce good filtering results, but they are also initially more expensive to buy than the previous two types of system. If you are not a handy sort of person, you will also have to consider the possibility of having to pay a plumber to install it for you.
Whole house filtration systems do just that - they filter the water as it comes into the house from the main supply, so every tap in your house is giving out filtered water. Naturally these systems are going to be the most expensive in general, because they are filtering a much larger amount of water. However, many people choose them because they feel they represent good value for the money, despite the larger initial outlay. They are hidden from view, and the cartridges last much longer, typically about six months or more. You are strongly advised, if you are looking to purchase this kind of system and you do not have a lot of technical skill, to employ the services of a qualified technician.
