Best Faucet Water Filters in 2021

Have you ever used the tap to get a drink of water and felt immediately turned off by the smell? No one wants to drink water that tastes and smells like treatment chemicals. And still, it’s vital we drink water.

Water filters not only help improve the flavor of your water but also protect you from impurities such as rust particles and harmful contaminants, impurities such as bacteria and lead. Sure, bottled water is easily available as a quick and (initially) cheap solution, but water filters are more sustainable and will save your money in the long run. It’s easy to check your water impurities using an at-home water test kit.

Fortunately, some of the filters can attach right to your faucet to eliminate the unwelcome substances you had to find in regular tap water. In this article, we give you the low down on everything you need to know about the best faucet water filters.

How does Filter work?

It’s a pretty simple concept water filters remove impurities and contaminants from your water. But what if we told you there is more than one type of filter? Before you get overwhelmed, we are here to clear up any confusion.

Activated Carbon

Activated carbon filters are among the most popular and use charcoal to pull out any impurities and contaminants from your water. It does this through adsorption that is when molecules bind to the surface of a compound.

These filters are best for removing unwanted chemicals, contaminants, and impurities. However, they won’t be able to rid your water of limescale, nitrates, and other “hard” factors.

While they will need periodic replacement as impurities clog the pores, they are a good option for anyone looking for a natural and clean way to filter their water. Not to mention, they will last a significant amount of time.

Reverse Osmosis

Osmosis is the channel of water through a semipermeable membrane, from a lower concentration of dissolved solutes to a higher concentration. During osmosis, the liquid is working to reach the equilibrium stage. Reverse osmosis, on the other hand, uses pressure to reverse this process and completely separate a substance from the liquid, rather than finding an equilibrium.

Reverse osmosis filters are a better option because they remove just about any harmful contaminants, impurities from your water supply.

Ion Exchange

When water comes into contact with the ion exchange filter, a chemical reaction happens. This removes dissolved ions such as sodium and magnesium from your water and then replaces them with ones of a similar charge. Ion exchange is best for dissolving sodium and magnesium from water.

Ion exchange water filters are also very effective in softening water. This can really come in handy if you are facing hard water stains that need removal.

These filters, however, require periodic use of a particular unique salt to keep from mineral build-up in the unit. If you want something with less maintenance, these filters may be inconvenient.

Distillation

Distillation is like a process of advanced boiling. After the water is boiled, steam is trapped from the water in a separate container. The trapped vapor then condenses back into water form. Distillation is the least common of the four household water filtration systems, but can still be very effective, and efficient.

This method can prove to be very effective in eliminating harmful bacteria and other contaminants, impurities including both organic and inorganic compounds. However, it’s a time-consuming process.

Why Faucet Water Filter is needed?

Before water reaches your sink/tap, it goes through quite a journey, traveling through a long series of pipes before making it to your home. On the way, dirt and other contaminants, impurities can land up into your drinking water.

Those bacteria and other microscopic organisms can make you ill. With a proper filtration system, you can eliminate those harmful organisms and improve the taste of water.

Here are some of the significant benefits of using a faucet water filter:

Filters remove sediment: No one wants to taste soil or clay in their water. While it is not an immediate health risk, but it can lead to bad-tasting water.
Reduce mineral levels: Minerals are important for the body, but not in excess levels. Minerals like iron and magnesium can also cause a metallic taste in water.
Get rid of pathogens: Filters are useful for keeping unhealthy bacteria from reaching your body. However, you will want to be sure to get a filter listed as micro, ultra, or nano.
Reduce chlorine levels: Most water treatment facilities use chlorine to kill bacteria before they reach the pipeline. Bad tasting water can be a result of this. Chlorine can also react to produce hazardous materials when passing over certain metals.
Removes lead and chemicals: Filters are also very useful in removing lead and pesticides from your drinking water.
