A faucet water filter is a good way to get pure drinking water from your taps at low cost. There are only a few things you need to know - but knowing them makes a big difference.
If you're considering the most basic, faucet-mounted filter, be wary. This is the kind that looks sort of like a fat bottle. You unscrew the faucet aerator and screw in the filter instead.
This kind of faucet water filter is better than nothing, at least for someone living alone. They are among the least effective water filters. In quality, they're about equal to the carafe filters - the kind that amounts to a jug you store in the refrigerator.
Besides the questionable dependability of the filter, these two types filter the least water, last the shortest length of time, and tend to cost a lot in replacement filters. You can also buy a throwaway faucet-mounted filter, among the poorest choices.
A major improvement is the counter top water filter. This type of faucet water filter also works by removing the aerator from the faucet and attaching the filter there. The big difference is, the counter top filter sits where its name implies, on top of your kitchen counter. High quality counter top filters are available, doing an excellent job of filtering contaminants from your drinking water. They couldn't be easier to install - just as easy as the faucet-mounted filters just mentioned.
The big differences besides the quality of the filtration:
A quality counter top filter will last a long time. With replacement filter cartridges readily available, it can last a lifetime. If you live in an apartment, it's easy to take with you when you move. The cost of clean, pure drinking water from these filters is a few pennies per gallon.
If it's important to you to keep your counter top uncluttered, and you'd like a more permanent faucet water filter, an undersink water filter can be a great choice.
This type requires some installation. Changes in the plumbing, the sink or the counter top are needed. If you're fairly handy, the undersink installation is an outstanding kind of faucet water filter. The filter is under the sink, out of sight. Your counter top remains clear and uncluttered. Many undersink water filters come with their own faucet for drinking and cooking water, leaving your other faucets free for washing.
If you're not a handy person, though - if changing a light bulb is about as complicating an operation as you want to deal with - then you either decide an undersink filter is not for you, or you ask a friend to install it, or you hire a handyman.
Both counter top and undersink water filters can do a great job, last a long time and deliver pure drinking water at very low cost per gallon.
