With the right inline water filter for your family’s needs, you can have a satisfying experience and feel rewarded in the purchase. After reading this guide, we’re hoping you can pick the right inline water filter with the qualities for which you’re looking.

  • Filtration Technology: Most inline water filters (sediment and carbon types) only remove common contaminants and improve the water’s aesthetics. Meanwhile, more advanced units (RO systems and ultrafiltration devices) can eliminate other impurities.
  • Filter Capacity: Nobody wants to replace water filters more frequently than they should. Hence, homeowners must pick an inline water filter with a high filtration capacity (i.e., 50,000 gallons instead of 20,000 gallons).
  • Space Requirements: Inline water filters connect to a section of an existing water supply line. The space should be enough to accommodate the water filtration system without requiring additional modifications.
  • Installation: Some inline water filters require expert installation (i.e., RO systems), while others are suitable for DIYers. Choose an inline water filter that you can install yourself to save on labor costs.

What Is An Inline Water Filter/ Who Is This For


In the past, a kitchen water filter system would entail having a separate filter right next to your main water tap in the kitchen. However, things are quite different now that there is an inline water filter.

An inline water filter removes this hassle as it enables the user to install this water filter underneath their sink. With this, the kitchen sink would not look as crowded, nor would it take up a lot of space.

Compared to other filter water systems, an inline water filter is also the most direct way to filter out your water supply. Since it’s right there under your sink and is installed directly into your main water line, it effectively filters out all the water that passes through it. With this, you’ll get cleaner and safer water for your household.

Moreover, this water filter will also improve the smell and taste of your water as it removes chlorine and other chemicals and substances.

An inline water filter is also the right choice if you are looking for versatility. Aside from your kitchen sinks or refrigerator lines, an inline water filter can be installed in other water lines and even in washing machines and other home appliances.

How Does It Work


An inline water filter provides a direct and very effective way of filtering out and removing toxins and substances from your water supply since it attaches directly to your main water line. After you install it, the filter will work immediately. Like all water filters, the inline water filter also comes with the mechanical and chemical filtration stages.

The first stage revolves around the use of a particle barrier. Depending on the type of filter medium, it can remove numerous particles, toxins, chemicals, and other impurities in your water. With this, you will get cleaner water.

The second stage is the chemical filtration process which is the most important. Tap water contains a lot of chemicals and other substances that are dangerous to our health. As such, to avoid contracting any diseases and sickness, there is a need to filter out the water supply.

The chemical filtration stage is responsible for improving the taste and smell as well as the cleanliness and toxicity levels of the water supply. Depending on the type of filter medium your water filter has, it can effectively filter out and remove various contaminants, viruses and bacteria as well as volatile organic chemicals and other toxins and substances.

What are the different types of inline water filters?

An inline water filter comes with its filter medium, which is responsible for the whole filtration process. Some models even have filter mediums that act as both mechanical and chemical filters. Due to the numerous mediums in the market, inline water filters differ from each other in this aspect. This section will list the different types available.

Charcoal Filters

Charcoal is a popular choice and is known for removing numerous toxins and other substances. Since charcoal contains carbon, it naturally attracts similar elements as well, which in turn, gets them filtered out of your water supply. This includes chlorine, fluoride, volatile organic chemicals, and other impurities and contaminants. These substances will then stick to your filter, which enables easy filtering and removal.

Carbon-Activated Filters

Carbon filters work in the same way as charcoal filters in that they sense that they also attract carbon-based chemicals and substances to them. With this, these impurities will stick to the filter medium for easy filtering and removal. As such, you will get cleaner and safer water.

Carbon-activated filters are also known to have excellent pores which can filter out sediments, sand, rust, particles and other substances. With this, the filter also improves the taste and smell of your water supply. Aside from this, the carbon-activated filter is also useful in filtering out chemicals, contaminants, viruses and other bacteria.

Granular Filters

Granular filters feature a blend of various filter media to target a wide range of chemicals and substances effectively. With different-sized pores, this filter can trap and filter out a lot of particles from your water supply.

As such, it’s certainly more effective compared to the other two and is recommended for those who have high water toxicity levels.

Unlike the other two, granular filters are also careful in not to filter out essential minerals in your water.

Advantages And Disadvantages Of Using An Inline Water Filter

Before purchasing a product, one should also consider the advantages and disadvantages it brings to see if it can truly fit your needs. This also applies when it comes to inline water filters. This section will list all the benefits and consequences a water filter may provide.


Save Space

Compared to other filtration systems, inline water filters are the most compact and space-efficient. Their size, design and construction are already smaller and more compact compared to the big and bulky designs of whole house filtration systems.

Plus, you get to save even more space since you can install your inline water filter underneath your sink.


Inline water filters are also quite durable and are known to have a lifespan of around 16 to 18 months. With this, you can save on costs and you won’t be placed in too much of a hassle. However, it is recommended that you always check and monitor the filter’s condition and change it when necessary.


Aside from your kitchen taps or refrigerator lines, you can also install and use your inline water filters in other water lines like your showers and the like. In fact, you can also even use it on home appliances like your washing machines, etc. Inline water filters can also still work in even low-pressure environments like boats, motorhomes, caravans, and the like. It can remove different contaminants from the water.

Inline water filters are also quite easy to maintain. Aside from monitoring and checking their condition and the occasional replacement, you really would not have to do much.


Needs Plumbing Experience

If you plan to install your inline water filter in showers, washing machines, and the like, it’s very easy to do since you just need to clip it or attach it. However, it’s a different story if you plan to install it under your kitchen sink. Here, you might need some prior plumbing experience or enlist the services of a professional since it can get quite tricky for a beginner.

Selective Filtration

While effective, inline water filters can only filter the water at the supply they are at. For example, you installed it under your sink. This means you can get filtered water out of your sink. However, if you want filtered water for your shower, then you might have to install a different inline water filter for that.

Buying Guide


Having an inline water filter is quite advantageous since you can get a consistent and constant supply of clean, filtered water out of your kitchen line. However, inline water filters differ in design, construction and the type of filter medium. As such, you might have a difficult time in choosing one. Luckily, this guide will help you in looking for one as it will list down all the factors you need to consider and look out for.

Type of Filter Medium

As already stated, inline water filters differ in the filter medium they use. Popular ones include carbon-activated, charcoal and granular filters.

Each of these types has different effectivity levels and rates as they target different chemicals, substances and other impurities. It’s most suitable to do your research in this aspect.

Charcoal and carbon-activated filters tend to focus more on carbon-based chemicals and toxins. They are also known for being effective particle barriers.

On the other hand, granular filters are more of an “all-around” choice since it contains a blend of different filter mediums.

Aside from looking at how well they eradicate pollutants and bacteria, it’s also recommended you get a filter that will also improve the taste and smell of your water supply.

Filtration Rate

This refers to how many gallons of water your filter can treat daily. This is usually indicated by a number with the GPD abbreviation, which means gallons per day. With this, you can roughly estimate how much water you can treat for a period.

In a way, this also points to the lifespan of your filter. Filters with high-filtration rates tend to be more expensive but are more effective, especially if you live with large households.

Replacement Costs

Another thing you should consider is how often you are going to replace your filter. This is important since these tend to be quite expensive, especially if you aren’t careful. Aside from this, you should also check the ease and accessibility of the replacement cartridges in addition to being easy to install.

It’s ideal to purchase a filter with a long lifespan and one whose cartridges are easy to find. However, there’s the problem of possible contamination if you leave the filter out for so long. As such, it’s best to monitor and check your filter’s status and change it if need be.

Installation Process

Inline water filters are quite tricky if you are planning to install them underneath your kitchen sink. If you have plumbing experience, then you wouldn’t have to worry.
