The Best Faucet Water Filter – Clean Water On Demand

If you do not have the time to go through this entire review and just want to find out what the recommended faucet water filter is, our top choice is the Culligan FM-100-C filter.

A water filter can improve the odor and smell of your water. It can also remove sediments, pollutants, and microbes. Here is what you need to know about choosing the best faucet water filter.

Installing a faucet water filter is an easy and inexpensive way of improving the quality of your drinking and cooking water. These filters are more affordable than other filtration systems, easy to install, and remove most sediments and pollutants. Here are a few recommendations to help you find the best faucet water filter.

How Do Faucet Filters Work?

There are different filtration systems and methods used by manufacturers. Some filters use screens or meshes to catch large particles, while others use carbon. 

Screens and meshes are ideal for removing sediments, sand, dirt, and metal particles. A carbon filtration system is best for removing chlorine, chemicals, and pollutants since the porous surface of carbon can absorb those molecules.

Public water supplies often use chlorine to eliminate bacteria and viruses. Low levels of chlorine are harmless, but high levels can be dangerous. You can remove chlorine from your drinking water with a carbon filter.

Depending on the filter you use, you can also improve the smell and taste of your water and remove metals from contaminated soil or water pipes, get rid of nitrates and nitrites, and reduce the risks of illness-causing bacteria and cysts being present in your water.

What Are the Main Benefits of a Faucet Water Filter?

Compared to other filtration systems, faucet water filters are easy to install. They provide you with clean water for drinking and cooking and tend to cost less than other types of filters.

I installed my faucet water filter in a matter of minutes and noticed a difference in terms of taste and smell right away. I didn’t need any tools for the installation, and the filter has helped me save a lot on bottled water, not to mention that it’s a more eco-friendly way to access clean water since there is no plastic waste.

I think a faucet water filter is an excellent choice if there are no major issues with your local water supply that would justify purchasing a multi-stage filtering system. It’s probably the easiest and most affordable way of improving the taste and smell of your drinking water by removing a wide range of sediments and other particles.

What Should You Consider When Choosing a Faucet Water Filter?

The best faucet water filter depends on the quality of your drinking water. If your main concern is sediments, any filter with a fine screen or mesh will remove those large particles.

If you are worried about parasites and microbes being present in your drinking water, look for a filter with a pore size of one-micron or less. An absolute one-micron filter is a better choice than a nominal one-micron filter since the CDC estimates that nominal one-micron filters still let between 20 and 30% of small particles through.

Microbial cysts can end up in water supplies and cause illnesses. The most common cysts include Giardia and Cryptosporidium. A filter that meets NSF/ANSI Standards 53 and 58 can reduce the presence of those cysts in your water.

Keep in mind that there are no regulations that require manufacturers to test their filters or meet certain standards. Some products do a great job of removing microbial cysts from your water even though the manufacturers chose not to go through the testing process that can be expensive and time-consuming.

You should also pay attention to the location of the diverter valve. You can’t run hot water through most filters because it would damage the carbon element. You will have to use the diverter valve whenever you need hot water or decide that you don’t need filtered water. Choose a filter with a diverter valve that is easy to use.

How Easy Is the Installation Process?

You can watch this short YouTube video to get an idea of how to install a faucet water filter.

The process will depend on the model you purchase, but you should be able to install most faucet-mounted water filters without any tools.

Here are the steps you would typically follow to install one of those filters:

  • Start by removing the aerator on your faucet. You can loosen it by tapping on the side with a wrench or another tool.
  • If you have a faucet with an outside thread, you should be able to screw the filter over your faucet.
  • If your faucet has an inside thread, you will need to insert a washer or O-ring and use the adapter that comes with your filter.
  • Test the filter to make sure there are no leaks. Add a second washer if needed.
  • You will need to change the filter every few months by removing it and installing a new one or changing the cartridge inside of the filter, depending on the product you purchased.
