So many of us would love to do the healthy thing, and drink water right off the tap. No more sugar, we say. No more empty calories. But we just can’t commit: the water tastes too bad! It’s time to put an end to this; filter out the bad, right at the faucet level.

How They Work: Best Water Filter for Taps & Faucets

First, let’s clear up a misconception: what these do is filtering, which is not the same as purifying. If you are dealing with contaminated water, the appropriate solution is a reverse osmosis system, or similar; something designed to make water pure. A faucet filter will certainly improve the quality of your drinking water, but to a more minimal degree. Therefore, it should only be used then the water comes already treated.

Generally speaking, a tap filter works in 3 phases: first, a screen around the cartridge blocks out sand, rust, and other types of sediment. Then, the water flows through a block of activated carbon, which traps certain contaminants present in the water. The carbon is called “activated” because it usually includes a chemical that allows it to catch other types of elements that it alone would be unable to deal with. Silver, for example, is often incorporated to prevent the passage of bacteria.

Important to note: most, if not all, of these filters can handle cold water only. They should not be exposed to hot water.

Benefits of The Best Water Filter for Taps & Faucets

Better water quality: Chlorine, microorganisms, heavy metals. Chemicals from pesticides. These are some of the elements that a filter will do away with. Your water will be freed from unpleasant odors and tastes. You will notice the difference, glass after glass.

Zero water waste: Every drop that comes through the filter, comes out appropriately processed. Nothing gets diverted.

No power consumption: They require no electricity, which helps both your utility bill, and the planet!

Filters can be recycled: That’s right! Often, the manufacturer will provide you with a shipping label so that you can send back the used filters. Failing this, there will likely be a recycling campaign in your area.

What Counts


The less often you have to trouble yourself with changing it, the better (not to mention the savings). This is measured by number of months, and gallons filtered.

Filtering speed

The longer the water stays in contact with the filter’s carbon core, the cleaner it comes out. This slows down the flow out of the faucet. Some filters incorporate technologies that allow the water to come out faster, while still cleaning it. This will be measured by gpm (gallons per minute).

What Gets Taken Out

While most filters remove the same range of contaminants from your drinking water, some will be more thorough than others. Fluoride and iron are a few examples of elements that not all filters will be capable of processing. You might want to have a general idea of what it is you’d like removed.

Filter change indicator

Who doesn’t like to be reminded of things we do only every once in a while —like changing a filter cartridge? A change indicator will tell you when it is time to swap. If there isn’t one, then you will need to note when you last did the change, and measure the volume of water you filter in your first week, in order to find out how much the filter works on a weekly basis. This is so you know when the month or gallon milestone has been reached.

Access To Non-Filtered water

You probably don’t want to keep the filter on duty while you’re doing dishes, for example. This will mean, after all, that a lot of filtered water will go straight down the drain. If you can run unfiltered water for certain tasks, your filter will be working only when it’s needed.


1. Housing: Some come in stainless steel; most of them are plastic. BPA-free is most desirable in the latter case, so you don’t have to worry about harmful chemicals eventually making it into your drinking water.

2. Swivel: useful to keep it out of the way so certain chores will be easier.

3. Finishes: Because aesthetics are also important. Getting to choose the right finish to match your kitchen’s scheme is sure to be a boon.


Not all kits are equal: They may come missing some accessories by default, or instructions could be incomplete. These filters are unlikely to require professional help, but we still want the process to be as easy as possible.


Also known as “does it really do what it claims to do”. Some filters will come NSF/ANSI certified, or be backed by organizations such as the Water Quality Association (WQA).
