The Mechanism: How Do Inline Water Filters Work?

Inline water filters are placed to sit directly on waterline or appliance so that the water passes through it before reaching the tap or appliance.

Considering the compact size, these filters are commonly used in household settings and are installed under the sink. One installed, the filter will run water safety checks and remove pollutants and contaminants in the water.

While different models of inline water filters may use different mechanisms to filter the water, the basic principle they follow remains the same. Here’s how they work in general.

When the water enters the filtration system, it first reaches a sediment pre-filter. This filter works to get rid of the large particles, such as sand, debris, rust, silt, or sediment. Apart from this, it is also responsible to keep the other filters working in optimal condition for long periods of time. So, basically, if there’s no sediment pre-filter, the next filters will warrant more frequent repairs and replacements.

After the water passes through the sediment pre-filter, it reaches the activated carbon filter. This is a crucial step because most of the contaminants in the water are removed here. This filter has a large porous surface that is lined with nooks and crannies, which attract the contaminants through a natural process called adsorption.

The activated carbon filter is responsible to remove most of the particulates, including chlorine, sediment residue, and any volatile organic compounds. It also takes care of any unpleasant smell and taste in the water. Sometimes, this filter is also treated with special substances to have different effects. In some models of inline water filters, a small amount of silver is added to the carbon filter to give it amazing antibacterial properties.

After the carbon filter, the water passes through the copper-zinc and mineral filter. At this point, any remaining contaminants are removed in the water, including chlorine and heavy metals. It also fights bacteria and other microorganisms found in the water as well as diminishes the scale in the water.

The next step is optional and some inline water filters may not have this but in some models, water goes through a water softener or a descaler. Manufacturers usually use ion-exchange technology for this. In this filter, the water passes over some resin beads, which are packed with sodium ions. These ions make the water soft and a bit salty. In some models, the natural taste of water is maintained through a salt-free softener.

Now comes the post-filter. This is where the quality of water is ensured. When the water reaches this filter, only tiny particles remain. The job of this filter is to make sure none of those particles reaches your water. This mesh-like filter is full of holes that are usually of 1-micron.

That being said, some inline water filters also have a UV filter to kill any escaped bacteria, virus, or microorganisms.

After passing these highly functioning filters, the water reaches your faucet. The entire procedure guarantees that the final water is pure, safe, and healthy for your everyday use.

9 Amazing Benefits of Inline Water Filters

Here are the top nine reasons why you should use inline water filters.

1.     No-fuss Filters

Users prefer inline water filters over other conventional filters because of the convenience it offers. These filters can easily be attached to existing kitchen taps, eliminating the cost of buying and the effort of installing a new tap.

2.     Versatile Option

The versatility of inline water filters covers two different aspects: applicability and filter media.

The applications of inline water filters are never-ending. Some models can be attached with kitchen tap, refrigerator, washing machine, and water cooler while others serve as a stand-alone filter under the sink. Many users use these filters for caravans, motor homes, boats, showers, icemakers, and drink machines.

In terms of filter media, they commonly feature a mixture of carbon and ceramic filter spheres, which play a major role in determining their efficiency in removing various kinds of contaminants and particulates.

3.     Unbeatable Filtration

Whether you choose to use an inline water filter in shower filters or caravans, it works beyond just removing unpleasant taste and odor from your water.

Some advanced models boast efficiency level so high that they are able to remove heavy metals, fluoride, and bacteria from your water, making it clean, pure, and healthy.

4.     Maximum Durability

Inline water filters are specially designed to be extra durable and resistant as compared to the standard filters.

Some models may last for up to 12 months without requiring frequent maintenance hauls. If you use them properly, you won’t need to replace them so often!

5.     Cost-efficient

For starters, inline water filters are super affordable that you can buy for your home or office. Apart from this, since it doesn’t require frequent repairs and maintenance, it significantly helps you cut down on your costs.

6.     Easy Replacement

Furthermore, for a seamless replacement process, the filter usually comes with a sign that indicates the direction of the water flow. This makes it easy for you to understand the direction in which you should install the filter without professional assistance and supervision.

7.     Save Space

Don’t have enough space in your kitchen cabinet or counter?

Don’t worry – inline water filters have got you covered!

These filters don’t come with huge, bulky hardware as compared to the majority of water filters. Hence, they are an elegant and efficient way of saving space.

8.     Work Great in Low-pressure Environments

Unlike the standard under-sink water filters, inline water filters don’t have any special water pressure requirements. Thus, they are an ideal choice for low-pressure environments, including caravans, motor homes, and boats.

9.     At Your Service 24/7

Inline water filters are always switched on for your convenience. This means that you get access to clean, filtered water whenever you turn on the water tap.

Unlike the standard under-sink water filters that provide unfiltered hot and cold water and filtered water through an extra tap, inline water filters directly filter the water flowing through your waterline.

3 Important Things to Consider Before Buying an Inline Water Filter

Here are just a few important things you must know before you buy an inline water filter for your washing machine, refrigerator, ice maker, or kitchen sink.

§  Purpose

As explained earlier, inline water filters are placed ‘inline’ with your current water supply line. This means that you’ll get purified water as soon as the direct water passes through the filter.

Is that exactly what you need?

Not to forget, there is no option of switching the inline water filter off. It is always switched on.

Hence, if you want every drop of water coming through your faucet to be clean and purified, you should be prepared to run maintenance checks and replace the filters often.

§  Location

Before you purchase an inline water filter, you should ensure that you have proper and enough space for it at your home.

Typically, it isn’t such a big problem because these filters are rather compact in size and can adjust anywhere. But of course, you need to have a specific location in mind beforehand.

Most inline water filters are around 10 inches long and they’re considerably heavy as well, which means you’ll need a sturdy, reliable mount for them. Please note that some filters do come with their own mount, so check all the pieces included in your package.

In addition to the 10 inches for the filter itself and some extra space for its mount, you’ll need to be proactive and leave a few additional inches around the unit. This extra space will make it easy for you to replace the filter without too much hassle in the future.

§  Replacement Costs

Since the inline water filter will be working 24/7 to provide you and your family with clean, filtered water, you’ll obviously have to replace it after every few months.

It’s important that you consider the replacement costs before buying one and find out how often the manufacturer says you’ll have to replace the filters. Based on that, calculate the estimated annual replacement costs if you’re following a budget.

It’s noteworthy that some inline water filters have a low upfront cost that may be tempting but in the long run, they offer very expensive filters.

Oftentimes, it is better to invest in a high-quality filter that may be a little expensive but may have lower replacement costs. This will work out best for your budget in the long haul.

If you think this is confusing, you can simply follow the instructions that come with the filter’s mounting kit – and it’ll make it easy for you to set up the connections.

Step 4: Place the Filter

Next, it’s time to drill holes on the compartment walls where the filter is supposed to be placed.

You’ll be provided with a bracket to help you place the filter. You’ll then have to use a screwdriver to fix the screws for attaching the water filter on the wall.

While you’re on it, make sure that you leave enough space near the screws so that filter replacement won’t be a problem in the future. Congrats – your filter has been installed!

Test 5: Test and Enjoy!

Once the installation is complete, don’t forget to test it by running the water. This will help you check for any leaks. If you notice any, fix it then and there.

That being said, to get the most of inline water filters, you should consider buying one that is certified and has a good water flow rate.
