By installing a kitchen faucet water filter, you can enjoy clean drinking water right from your faucet with fast water flow, quick and simple installation, and take up virtually no space (just make the faucet head look bigger overall).

Below are some of the benefits of having a faucet mount water filtration system.

Healthy Tap Water

While municipally treated tap water may look clean with bare eyes, it’s, in fact, contain many harmful contaminants that can’t be seen such as lead, cysts, fluoride, bacteria, and mercury.

These harmful contaminants can cause serious damage to the human body if taken in excess amount for a long period of time.

Thus, it’s crucial to install a water filtration system at home for safe and clean water.

When I’m moving home, a water filter is always on my compulsory list.

Save Money

Did you count your annual expense on bottled waters?

I hope you did.

You’ll be surprised how much money you can save by using a faucet filter instead of buying bottled waters, and the figure gets bigger with the numbers of your family members.

Great Water Taste

The filtered water has much greater taste compared to unfiltered water. It can make your freshly brewed coffee and tea taste better and richer.

Since you are drinking water every day, why not make it taste better at the same time when quenching your thirst?

Protect The Environment

Do you know that a single faucet filter cartridge can replace 1,000 to 3,000 plastic bottled waters at 16.9 oz each?

By installing a simple kitchen faucet water filter on your faucet, you can contribute your little help in protecting the environment by reducing plastic bottle waste.

Easy and Fast Installation

In terms of installation, most faucet mount water filters are quick and simple to install with no tools are required.

Just buy and attach on your faucet for clean tasty water.

Some faucet filters have even more options, like spray water or high-pressure water.

There’s also a handful of benefits by using a faucet mount water filtration system over other common types of filtration system:

  • Compared to pitcher: Faster water filtration rate, more convenient as no fill-ups is needed, and no tabletop or fridge space is required.

How to Choose the Best Faucet Water Filter for Your Home (Buying Guide)

There are several factors I took into account when preparing this list of best faucet water filter for well water and city water, and I think this is how you should choose your faucet water filter as well.

They are:

  • Filtration performance
  • Filter lifespan
  • Cost
  • Design

Filtration Performance

This is the main point of getting a faucet water filter, so if the filtration performance is low, you should never consider it even if it’s cheap.

Depends on your water source quality, some may have more lead content, fluoride, or other contaminants. So, pick a kitchen faucet water filter according to your water quality.

Filter Lifespan

Filter lifespan determines how frequently you need to change a filter cartridge.

If you’re just one person, it’s alright to choose a faucet filter with standard capacity, which is 100 gallons of water filtration or 2-3 months of usage.

But if you have more family members, it’s better to pick a faucet filter that lasts longer.

Filter Cost

The price point is always one of the main factors in purchase consideration, no doubts about that.

There are two types of cost you need to consider here. First is the upfront cost to get a faucet filter, and the second is the ongoing cost for filter cartridge replacements.

For instance:

Filter A: Upfront cost is $30 and the ongoing cost is $7

Filter B: Upfront cost is $20 and the ongoing cost is $11

So, which one is better in terms of cost?

To make it simple for you, just calculate the cost for one year with the assumption of 2 months replacement frequency will do.

Results:

Filter A: $30 (last 2 months) + $7 x 5 times = $65 annual cost

Filter B: $20 (last 2 months) + $11 x 5 times = $75 annual cost

Thus, Filter B is better for you in terms of cost.

In short, the cheapest faucet filter doesn’t mean giving you the best value, if you are looking for the best value faucet filter , I’ll recommend you to get the Waterdrop WD-FC-01.

Filter Design

Yes, since everyone walk into your kitchen will have a high chance of seeing this little guy, therefore it has to be nice in terms of aesthetically, right?

As a faucet water filter, the Engdenton faucet water filter does its job perfectly by providing a basic water filtration to supply clean and tasty water constantly to you and your family.

The good about using a faucet water filter is there’s no extra space needed to store the water filter system, just install it to your faucet (few minutes) and get your filtered water.

Also, the nice-looking robust 304 stainless steel faucet filter housing is definitely worth the additional top-up as it can sustain high water pressure and prevent you from the trouble of water leakage issue due to filter housing crack (it makes your kitchen look classy).

FAQ for the Best Faucet Water Filter

Here’re the answers for the frequent asked questions about faucet mount water filter:

1. Why my filtered water is black in color and has many black dots?

Simple, because the most common material used in a water filter is carbon, so it’s completely normal if your first few rounds of filtered water is black color (that’s the color of carbon isn’t?) or have black dots (that means the carbon is newly manufactured from the factory, it’s a burned wood right?).
 
I know, a lot of bad product reviews is talking about this matter, just ignore those reviews unless they mentioned after a few hours of usage is still the same (and with proof).

2. Why my filtered water TDS meter reading is high?

TDS meter is only used to estimate the total dissolved solids in the water, based on the conductivity in water. 
 
That means the minerals in the water will contribute to TDS value too, and most faucet water filter is not designed to remove those.
 
In short, the TDS meter is only suitable to use to estimate effectiveness of Reverse Osmosis water filter.
 
There are many bad reviews are given because of this matter, due to the lack of correct understanding about TDS meter readings from users.
 
Really, I feel pity for the seller who received those unfair bad reviews.

3. Can a TDS meter really measure the Total Dissolved Solids in the water?

The answer is no.

I have seen many people used a TDS meter or TDS pen to measure Total Dissolved Solids in their water without knowing what is really being measured.

In short, what TDS meter measured is the electrical conductivity (EC) in water (pure H2O has virtually zero EC), and then times the EC value by a factor between 0.5 to 1 (set by the manufacturer) to estimates the TDS (which is not the real Total Dissolved Solids in water).

For instances, dissolved organic solids (eg: sugar) and microscopic solid particles (eg: colloids) are not measurable by the TDS meter because they do not affect the water conductivity significantly.

The accurate way to measure the actual TDS in water is to evaporate the water and then weighing the dissolved residue left.

4. Is the water filter brand important?

Not absolutely but is recommended if it’s a reputable brand in term of product safety, quality control and customer support.

As we discussed earlier, the important parts of considering a water filter are about the material of the components, where the components are manufactured, and the functionality of the filter system.

So more importantly, choose a water filter which all its components are manufactured by reputable companies with strict material control and strict quality control (eg: US-based manufacturers).

5. Is NSF certification required?

The answer is no, but it’s recommended to have NSF certified for all components that have contact with water (especially for smaller brands).

NSF is a certification system and not a quality control system, so it can’t guarantee the filter performance in the long run and the quality of your filter when it’s manufactured (since thousands of filters are being manufactured and shipped to customers directly without going through NSF).

6. How to know whether the filter cartridge is clogged or it’s time to replace?

You can measure the pressure drop by installing pressure gauges before and after the filter.

When the filter cartridge is new, run the water filtration system and write down the difference of pressure reading (let’s say 2 psi). Then measure again after a few months, you’ll notice the pressure difference is increasing, let’s say to 7 psi.

When the difference of 2 pressure gauges reading reach about 15, it’s time to change the filter cartridge (or wash if it’s washable).

Conclusion: The Best Faucet Water Filter Is Filter That Fits Your Needs The Most And Priced Reasonably
