Why Use Inline Water Filters?

There’s a time where you don’t need a filtration powerhouse like the Reverse Osmosis system to perform certain tasks, such as basic water filtration for the refrigerator, ice maker, faucet, RVs, boat, washing machine, and dishwasher.

And that’s the reason why you need a single or double stage water filter.

It’s used when a higher direct flow rate and compact size are required.

You can install an inexpensive inline water filter before your refrigerator and ice maker to produce tasty cold water and ice.

You can get a budget one-time-use inline water filter for your RV when you are traveling for a few months, without spending a fortune on an expensive water filtration system.

The list goes on and on, there are so many occasions that you should use an inline water filter because of how great and convenient it is.

Do note that these water filters with a single water filter cartridge are not supposed to be used as a replacement for a multi-stage whole house water filtration system unless your water quality is excellent.

It’s an additional point-of-use water filtration system to further improve the water quality for specific purposes like ice making.

They are used in a wide range of home filtration applications such as faucet, refrigerator, ice maker, washing machine, coffee machine, water cooler, and garden.

How to Choose the Best Inline Water Filter [Buying Guide]

To better guide you in choosing the best inline water filter for ice maker, refrigerator, and faucet for your home, I’ve prepared this buyer guide for you.

This guide is written to help you understand more about different types of inline water filter so that you know which one is the best inline water filter for your house.

To make the right purchase, first, you have to know what you need.

Here are some of the important factors that you should think about before buying the inline water filter:

  1. Know your water quality
  2. Types of inline water filter media
  3. Contaminants removal
  4. Filter capacity
  5. Installation and replacement
  6. Price of the inline water filter
  7. NSF/ANSI Certification for the Inline Water Filter
 

Knowing Your Water Quality

Depending on where you stay, and what type of water source you use, the water quality will be different.

To decide on the best inline water filter for your home, you’ll need to understand the quality of your water, mainly what kind of contaminants are inside your water.

If your water quality is okay, you may choose an activated carbon inline water filter with micron-size 5 to 10.

If your water quality is moderately contaminated, then choose an inline water filter with higher filtration strength of 0.5 to 1-micron rating, such as Frizzlife filter, it’s the best inline water filter for under-sink use.

If your water contains a certain amount of heavy metals, then choose an inline water filter with KDF media.

If you are using chlorinated water, then an activated carbon inline filter is your best choice.

Types of Inline Water Filter Media

There are mainly 3 types of inline water filter media, which are:

  1. Activated Carbon Block (ACB) filter
  2. Granular Activated Carbon (GAC) filter
  3. KDF filter

The activated carbon block and granular activated carbon are similar media in different forms. Both of them are highly effective in removing chlorine taste and odor, chemicals, VOCs, and more types of contaminants.

The KDF filter is effective against heavy metals and many other contaminants. Besides, the KDF media can inhibit bacterial growth.

Types of Inline Water Filters

There are few types of inline water filters which are designed for specific purposes, such as:

  • Under-sink Inline water filters for faucets
  • Inline water filter for ice makers or refrigerators
  • Inline water filter for RVs and campers

Under Sink Inline Water Filters for Faucets

These under sink Inline water filters are designed to be installed on the under-sink area to purify water flowing out from your faucets.

The filtered water can be used to wash food ingredients, vegetables, fruits, and dishes and even drink (if the water quality is good).

You may check out the best under sink Inline water filter here.

Inline Water Filter for Ice Makers or Refrigerators

These types of Inline water filters are made to attach to your ice maker or refrigerator easily to produce clean cold water and ice cubes.

Besides, they are easy to maintain and replace filter cartridges, as the maintenance work needs to be done indoor in your kitchen.

You can check the best inline water filter for ice maker here, and the best inline water filter for refrigerator here.

Inline Water Filter for RVs and Campers

Traveling with your RV? An active camper?

No problem, there are plenty of Inline water filters that are specifically designed for RV and campers like you!

This type of Inline water filter usually contains KDF media, which is great in water filtration and inhibits bacterial growth at the same time, so you can keep the Inline water filter after each use and continue to use it again on the next stop or next trip.

Here is the best Inline water filter for RVs and Campers.

Contaminants Removal

The majority of the inline water filters come in either one-stage or two-stage water filtration.

Since most of them are built with an activated carbon filter which removes a majority of common contaminants like sediments, VOCs, and chlorine taste and odor, so what you need to consider is whether you need to remove certain contaminants like lead, heavy metals, and chloramines.

Next is whether you need a filter that contains KDF media to inhibit bacterial growth, like RV or camping activities which you may not use the filter for some time.

 

Filter Capacity

If you have more family members in the house, it’s better to pick a higher capacity inline water filter to last longer for each filter replacement.

Higher filter capacity means lesser filter replacement frequency.

 

Installation and Replacement

I bet you won’t want to hire a plumber to come over just to install a water filter right?

Luckily, there are plenty of inline water filters that use Quick-Connect or Twist-in Twist-out installation design, which make the filter installation and replacement process a breeze for all people.

All inline water filters featured in this review are easy and quick to install and replace.

Measure Your Pipe Diameter

Generally, there are 2 sizes of pipe, which are 1/4 inch and 3/8 inch in diameter.

So make sure you have measured the size of your pipe before ordering to avoid additional work and cost to buy additional fittings and adapters.

 

Price of the Inline Water Filter

The price factor is always a factor for purchase decisions, and no matter how cheap it is, consumers tend to get the best value off their bucks.

Sometimes, it’s not solely about the price tag (unless you really can’t afford it), it is more on the value.

The filtration performance, features, and capacity you get per a dollar spent is a more precise indicator for which inline filter you shall go with.

NSF/ANSI Certification for the Inline Water Filter

The two most common NSF standards for water filters are Standard 42 (for more than 90% reduction of chlorine taste and odor) and Standard 53 (for reduction of volatile organic chemicals, inorganic compounds, and heavy metals). 

I can’t say the inline water filters without NSF certification are bad in quality or worse than those certified by NSF, because it’s not always true.

It’s not cheap to get NSF certification for a water filter, so the high cost may stop some water filter manufacturers from getting their products certified so that they can price their products cheaper.

But anyhow, the filtration capabilities of the NSF certified inline water filters are proven with official test results, which are safer and trusted choices for your family.

How Long Can Inline Water Filters Last?

Most water filter manufacturers stated the expected filtration capacity in gallons, which indicates how many gallons of water it can filter before replacement.

Some manufacturers only stated the expected lifespan in time, like 3 months, 6 months, and 12 months, which are less accurate because it didn’t factor in the water usage.

Some Inline water filters come with both lifespan indications like 1,000 gallons or 6 months, whichever comes first.

But the actual filter lifespan depends on the water quality as well, especially if you do not install a sediment filter before the inline water filter.

A more accurate way is to monitor the pressure drop and test the water with a test kit to decide when to replace the filter.

Should You Buy Inline Water Filters?

The answer is yes. Most water sources are contaminated, it is just a matter of more or less.

For your health, your family, your home appliances, fixtures, and pipes, this little investment is worth it.

Aside from being more affordable compared to other filtration systems like RO system, multi-stage filtration system, and whole house filtration system, inline water filters are also smaller in size and easier to install and replace.

Just make sure the Inline water filter you buy is good quality.

For quality assurance, you can pick from the top 10 list of best Inline water filters.

How to Install Inline Water Filters for Ice Maker, Refrigerators, and Faucet

Most inline water filters are designed to be installed easily on existing piping lines, but if you have no prior plumbing experience, it’s recommended to watch the instruction manual or online video before you start installing.

For some inline water filters, you just have to cut the existing line that connected to your faucet or refrigerator, install the inline water filter, and connect the lines to its inlet and outlet.

Here are the basic tools you need:

  • Pipe cutter
  • Wrench
  • Screwdriver
  • Drain bucket
  • Drill
  • Fittings like converter and elbow
  • Screws
  • Cloth

Have everything ready?

Follow these steps:

  1. Shut off your main water supply.
  2. Do marking on where you want to install the holder for the inline water filter.
  3. Drill a few holes and install the Inline water filter together with its holder.
  4. Cut the pipe and connect it to the inlet and outlet of the water filter so that the water must flow through the inline water filter.
  5. Tighten the nuts to prevent leaking.
  6. Clean the spilled water with a cloth and a bucket.
  7. Double-check every connection is tight.
  8. Turn on the main water supply and test run the Inline water filter to check is there any leaking.
  9. Let the water run for 20 to 30 minutes for flushing.
  10. Done!

What Are Essential Minerals?

Essential minerals are something your body cannot produce naturally but are required for your body function to work correctly and stay healthy.

The water filter will remove most contaminants in the water while leaving the essential minerals.

These essential minerals are dissolved solids, which increase the total dissolved solids (TDS) value of water.

Some of the essential minerals are calcium, potassium, magnesium, sodium, phosphorus, and chloride 

Calcium – Essential minerals in the body to build strong bones and teeth. It’s required in the physiological and biochemical processes of organisms and cells.

Potassium – It plays a vital role in maintaining a normal heart rhythm of your body and the pH balance of the blood. It’s also required to build proteins for your body.

Magnesium – Essential to support muscle and nerve functionalities and maintaining your heartbeats. It is also used by your body to support various biochemical reactions and boosts immunity.

Sodium – Required to maintain the right balance of fluid in the cells and stimulate muscle and nerve function. Sodium also supports the absorption of nutrients like glucose, amino acids, and chloride.

Phosphorus – Required to build strong bones and teeth, repair cells, and produce proteins for the body.Chloride – plays a vital role in the production of the digestive fluid in the stomach and balances the fluids in the body.
