Testing your water to find out whether there are harmful germs or chemicals in it will help you choose a filter. If your water is free from harmful germs or chemicals, you may decide you do not need a filter. If your water has harmful germs or chemicals, choose a filter that removes those germs or chemicals.
If you get your water from a private well or a rainwater collection system, test your water at least once each year for harmful germs and chemicals. Also consider testing your water if you notice changes in color, taste, or smell.
Contact your health department for advice about what to test for and how to find a state-certified lab to do the testing.
If you get tap water from a public water system, review the water quality report your utility must provide every year. The report will show if there are harmful germs or chemicals in your water.
The pore size is the size of the tiny holes in a filter that let water through. Filters work like strainers or colanders. As pore size gets smaller, fewer types of germs and chemicals get through the filter.
If a filter has an absolute pore size of 1 micron, for example, each one of the filter's pores is 1 micron or smaller. This means that anything larger than 1 micron will be caught in the filter and removed from the filtered water.
Filters with a nominal or mean pore size of 1 micron have an average pore size of 1 micron. This means that some pores are smaller and some pores are larger than 1 micron. These filters will let some things that are bigger than 1 micron through the larger holes.
NSF International is an independent organization that develops public health standards for products. One way to figure out what a water filter removes is to look for an NSF certification on the filter's label. You can look up specific products in the NSF database to see what they are certified to remove from water.
Some of the NSF standards related to water treatment are:
Point-of-use filters usually filter water in batches and deliver it to a single tap, such as your kitchen sink. These include under-sink filters and those that attach to your faucet. Consider point of use filters if you only need to filter the water you drink and cook with, for example.
Whole-home filters, also called point-of-entry filters, filter water as it comes into your home. This means all your water, from every tap, gets filtered.
Consider these filters if you need to remove a harmful substance, such as certain volatile organic chemicals, from all your water. This includes water you use to bathe or clean with, as well as water you drink or cook with.
Keep in mind that if you install a whole-home filter that removes chlorine or other disinfectants, more germs may grow in your plumbing.
You will need to maintain any filter you use to keep it working properly and prevent germs from growing in it. This includes regularly changing the filters according to the manufacturer's recommendations. Wear gloves while you change filters and wash your hands afterward to avoid getting sick.
Some filters also require pre-treating water before you filter it to protect the filter and make sure it works properly. Examples of pre-treating include adjusting pH or adding powdered activated carbon.
