Why Is Filtering Tap Water So Important?

You should not underestimate how much you use water from the tap and how much it actually affects your life, health and well-being.Effects of Hard Water

Think about all the things you rely on tap water for.

Cleaning, cooking, washing your hands, washing dishes, drinking, filling up the kettle or coffee maker, washing expensive home appliances, mixing tap water with food and drink etc.

How do you feel about using hard or contaminated water to do these things?

If you’re reading this article then chances are that you’re the type of person that cares deeply about what you put in your body and the quality of your surroundings.

Is Hard Water Bad For YouStill not convinced? Here are some concrete reasons why filtering your tap water is very important:

  • Hard water leaves white residue on your kettle, pots, around your sink and in your expensive kitchen appliances. This not only ruins the appearance of these items but sometimes stops them from working properly.
  • Overtime, your pipes can become clogged and shower heads suffer from residue build up if you don’t filter out water hardness.MyTapScore Home Water Test
  • Water companies and government agencies can sometimes add things to the drinking water supply of a population. Things like fluoride or chlorine. You may want to give yourself the option of not consuming this.
  • No more ugly limescale and residue buildup ruining the look of your kitchen.

The biggest selling point of the advanced PUR faucet filter is that it “installs with just 1 click.”

You can do this without any tools. All you have to do is screw the adapter on your tap. That’s it. The PUR tap filter just snaps on.

It comes with 3 adapters that allow it to fit a range of different tap sizes. This means that it is likely to work with whatever type of tap you already have. mrwatergeek winner badge

However, note that some faucets (e.g. the large pull-out taps faucets) do not work with the PUR.

It can filter around 100 gallons, which will last you around 2-3 months before you need to replace the filter.

One of the best things about this tap system is it uses a 3-stage filtration process. This system removes up to 61 contaminants.

2. Culligan FM-15A Faucet Filter

Culligan FM-15A is by far one of the best selling water filter faucets on the market. And it’s not hard to see why.

This faucet can filter 200 gallons of water before the filter needs replacing.

My only reservation with this faucet water filter is that it does not come with a filter replacement indicator. This means there is no way of knowing when the filter needs to be replaced.

The replacements are easy to find on places like Amazon.

  • White
  • Polished Chrome

3. Protect Plus WFFM350XCH DuPont

I have added the WFFM350XBN to my list because it comes highly rated.

DuPont’s faucet filter is one of the most technologically advanced tap water filters on the market.

As you can see from the picture it even has a screen display telling you how many gallons it has filtered.

But, even though it looks very advanced and technical, it is super easy to setup. No extra tools, no screws, no plumbing knowledge required. All you have to do is screw it over your existing tap.

Q. I have an usual shaped tap faucet can I still use it?

A. Yes, the DuPont WFFM350XBN comes with adapters so that you can fit it onto different types of faucets.

As with some of the other tap filters in this list so far, it let’s you decide whether to have filtered or unfiltered water. This is simply done with a flip of the switch.

DuPont WFFM350XBN comes with a 4 year warranty and it reduces sediments like:

  • Benzene.
  • Lindane.
  • Chlorine.
  • Cysts.
  • Mercury.

The F2BCTU-1ES comes with a 1 year warranty and has an external quality certification from the NSF.

How to Install a Faucet Water Filter?

Here are the basic steps to install your faucet water filter.

Step 1: Turn Off Your Water Supply

Step 1 is to turn off your water supply direct at source. It is unlikely that anything will go wrong but if something does, you don’t want to cause a flood. To turn off the water supply, look for the valve (usually under the sink where all the pipework is) and manually turn the key on the pipe that supplies water to your sink.

Step 2: Remove The Existing Faucet Aerator / Measure The Water Outlet

This is a little screw on spay that is under the tap (where water comes out from). Once you have located this, unscrew it. Keep it in a safe place because you will need it later.

If your tap does not have an aerator then make measurements of the outlet in height and width. This is so you can easily determine which adapter is the right size for your tap.

Step 3: Find And Screw In The Right Adapter

Now that you have your old aerator or at least its measurements sorted, it’s time to fine the right fix. Almost all faucet water filters will come with multiple adapters for you to choose from. So either use the measurements or existing aerator that you unscrewed to determine the right adapter.

Step 4: Screw In The Right Adapter

Once you have found the right adapter from the one’s supplied with the tap filter, screw it on to your tap.

Step 5: Click Your Filter Into Place

Your faucet adapter is now snugly screwed in. Check to make sure that it is tight so that you avoid any leaks.

Which is The BEST Faucet Water Filter?

Mr Water Geek ThinkingThe DuPont WFFM350XBN is the best faucet water filter.

Let me tell you why.

It mounted faucet water filters is a convenient way to make sure you have access to clean filtered drinking water direct from the tap. mrwatergeek winner badge

The device literally filters the water on-demand when you turn on the tap. This makes it some of the fastest filtration processes out there today.

It is one of the easiest to install and has low/no maintenance.

PUR would have been my favourite but it only does 100 gallons, while the DuPont does 200 gallons and costs a similar amount of money.

The on-screen countdown not only tells you that it is working i.e. how many gallons it has filtered. But it also let’s you know how long to go before a replacement is needed.

This means you can pre-order the replacement filter in good time and you can avoid last minute dashes to the store.
