When you are buying a faucet mounted water filter, there are a few important aspects that you need to understand.
Faucet mounted filters are not water purifiers. They just filter water. For example, the advanced filtration techniques such as reverse osmosis, ion exchange etc., are not used in faucet mounted water filters. Once you are clear about this difference your buying decision will be easy.
So what does this mean to everyday folks? This means that, if your water is microbiologically unsafe then any amount of filtration using a faucet mounted filter will not help you.
Typically your faucet filter will contain a mesh filter followed by filtration by carbon block and zeolite. The carbon blocks have millions of micro pores which act as the filtration mechanism.
They can effectively remove chemicals such as chlorine and sulfur.
There are also several advantages in using a faucet mounted filter.
- They are very easy to install by any average user. Due to this they are very popular with renters and apartment dwellers.
- Most faucet mounted filters provide a bypassing mechanism to choose between filtered and unfiltered water enabling to use the filter only when drinking water is required. This will help you extend the life of your filter.
- Finally these filters are the least expensive among other types of in-line filters.
