The Most Important Things When Buying an Inline Water Filter
We are aware that there is a lot being presented to you right now. It can be difficult to choose the right inline water filter. Some require pre-installation, while others can be used with an existing water supply.
We consult with customers around the globe so we can help you choose the best inline filter or point you in the right direction.
When choosing an inline water filter, there are many things to consider. These are the steps to follow and some key facts to consider before making a decision.
What Is an Inline Water Filter?
Inline water filters are thin, long filter cartridges that connect up to your home’s waterline. These filters are space-saving and easy to install. They can be placed anywhere along your waterline, from the point of entry (POE) to the space below your kitchen sink.
Water Use and Filter Life
One thing that we have always looked at when evaluating inline filters is their life expectancy. One of my most frequent questions is “How many gallons can I run through the filter before it needs to be replaced?”
This is a great question. Most filters have an expected lifetime or a general timeframe for when they should be changed. It will differ from person to person depending on how hard or how much they drink. The fact is that your filter’s life span is determined solely by how much water it receives.
Your usage will be lower if you have a smaller family or even a couple. The less you use the filter, the longer it will last. It is important to know how much water the filter can withstand before it needs to be replaced. The filter you are considering may only state “6 Month Filter Live”, but that is not the truth.
I advise people to always have an extra water test kit in case they need it. This will allow you to check the water and determine when the filter is not working properly.
Inline water filters are thin, long filter cartridges that connect up to your home’s waterline. These filters are space-saving and easy to install. They can be placed anywhere along your waterline, from the point of entry (POE) to the space below your kitchen sink.
What Is the Secret to Their Success?
Inline water filters make use of the pressure from your plumbing to force water through a filter, or series of filters that trap contaminants.
If you turn on your cold water faucet or press the water button to get water from your fridge/ice maker, the water will pass through an inline filter and arrive at your refrigerator, icemaker, or faucet as filtered.
From start to finish, this will only take a few seconds.
Most inline water filters use carbon-based technology. They use adsorption, which traps impurities and prevents them from contaminating water or ice.
Adsorption is the process of binding water molecules to solids, in this case, the micropores in the filter. These contaminants stick to the filter, and cannot pass through with smaller water molecules.
What Are the Best Times to Use an Inline Filter?
If you’re looking for an easy and convenient way to filter your water, an inline water filter will be the best choice.
An inline water filter has the advantage that you do not need to replace it once it is installed. In some cases, the filter can last up to five years. You can have clean water and not worry about changing filters or cleaning the system.
High-contaminant water drinking water is best treated with inline water filters.
However, the removal of contaminants varies from one system to another. The best inline water filter systems do a fantastic job filtering chlorine taste and odor. Many of them are NSF certified for chlorine removal so they are a great choice if your water contains high levels of chlorine.
Tip: If you aren’t sure what contaminants your water contains, you can order a test kit to determine if you need a filter.
A water line filter can be connected to your water supply to make it more efficient. This filter is useful for those who don’t have fridge filters and still want to drink tasty and clean tap water cooled in a fridge.
Although you may see the best inline water filter that is meant for use with an icemaker, it is rare to find one that can be used for that purpose.
The filters can be connected to your water line and most homes have the same gauge. You can connect your filter to your water line to use it for any purpose you like – your fridge, freezer, fridge and icemaker, or faucet.
Types of Inline Filters
The exterior appearance of inline water filters is similar. They are cylindrical and long and have fittings on both sides to connect to your water supply. Different line water filters have their own filter materials inside the housing. These are the most popular types of filters used in best inline water filter systems:
Activated Carbon
Most activated carbon filters are used in water filters that are inline. An activated carbon filter uses the process of adsorption in order to trap contaminants within its filter media. This filter is particularly effective in removing chlorine taste from water.
Charcoal
Charcoal filters, which are another type of activated charcoal media, use the same adsorption process as activated carbon media to purify water. The activated charcoal is used to bind the contaminants to the media during adsorption. This prevents them from passing through the system with water.
Carbon Block
Another filter that is similar in sound and performance for inline filtration systems, the activated carbon block filters. Carbon block filters are made from compressed activated charcoal that has been ground finer than granulated activated. This prevents the formation of flow channels and provides a more efficient filtration.
Advantages and Disadvantages Inline Filters
An inline water filter offers many key benefits. They definitely improve the drinking water quality and its taste.
Multiple Appliances Can Filter Water
You may be able to use the same inline water filter on multiple appliances depending on which brand you choose and where you place it. You can use many inline water filters for your refrigerator’s water, ice maker, and kitchen tap. You can also use the filter to filter water from one appliance, such as your refrigerator or tap water.
Option Affordable
Inline filters are the most affordable water filter option when compared to other water filtration systems. Line water filters can be a great option if you are looking for a long-lasting, affordable water filtration solution for your fridge, tap water or ice maker.
It Is Easy to Install
The best products have easy-to-install fittings that make it simple to attach the filter to the supply. You don’t need to hire a plumber to help you install the filter, even if you aren’t a DIY enthusiast.
Low Maintenance
Inline water filters are more durable than other water filtration systems that require regular filter changes and weekly cleaning. They can be left alone for many months with no maintenance. Line water filters last at least six months so you don’t have to replace them as often as other filters.
Water Filtration by Discreet
The best inline water filter can be installed in a cupboard or another discrete location. It will filter the water for your fridge and ice maker. You don’t need to display your inline water filter like countertop filters. It’s small enough that it can be installed out of sight.
Drawbacks of an In-Line Water Filter
Installation Is Not for Everyone
Although inline water filters are made to be as simple as possible to install, it is still a difficult task that requires plumbing knowledge to complete successfully.
It’s Not a Complete Home Solution
Even the most powerful line water filters can’t filter water for your entire home. An inline water filter can only be installed in your refrigerator, icemaker, or kitchen sink. The filtration system won’t be powerful enough to supply clean water for all of your home’s appliances.
It Doesn’t Provide the Most Comprehensive Contaminant Removal
Although they are useful for chlorine reduction only, some inline water filters can remove heavy metals. An inline water filter won’t provide you with complete contaminant removal.
There Are Some Things to Consider When Buying an Inline Water Filter
Eliminating Contaminants
An in-line water filter can almost guarantee that your water will be free from chlorine taste or odor. Many filters are NSF certified to prove this. They can also remove sediment, dirt, and sand from your water. This will help to keep your fridge’s icemaker in tip-top condition.
Inline water filters can remove bacteria and microorganisms. Some also remove trace metals such as lead. Although many people who have line water filters claim they no longer have hard water due to using them, it is rare for an inline water filter to be able to soften the water. This would require a completely different process for water conditioning.
Flow Rate
The flow rate of water through an inline water filter system can be a problem because it is connected to the main water line. It is important to have immediate access to your ice maker or your water faucet without waiting for the water to pass through the filter. The system in the best inline water filters doesn’t affect the rate until it reaches the end of its life, at which point it might be too clogged with contaminants to filter water quickly.
Capacity
A typical inline filter has a capacity of 3000 gals (which is roughly 6 months) or a capacity of 20,000 gals (or about 5 years). The capacity of a filter is not necessarily a lower-quality one. It just means that it will be more expensive upfront and will need to replace more often.
It’s usually cheaper to pay $30 to $40 for 5-year filters than $20 for half-year filters. This will save you money over the long term. Many in-line water filtration systems advertised to have a long life expectancy don’t last as long as they should. Customers have complained that their 5-year systems only lasted for a few years. This is a good thing and still a great deal. However, it is something to keep in mind.
Physical Size
Inline water filtration systems are usually small due to their capacity and the ability of the manufacturer to create something that is space-saving. The size of your filter system doesn’t really matter if you have enough space in your basement, kitchen or anywhere else you want to put it.
For example, if you intend to install an inline filter water filter behind your refrigerator or in cabinet space, then you will need something small enough to fit.
Best Inline water filters typically measure around 10 inches in size. The width of filters can vary greatly, with some filters being 2.5 to 3 inches wide and others measuring more than 6 inches. Most filters measure between 2 and 4 inches high.
Filter Certifications
NSF Standard 42 is the most popular certification for inline drinking water filter systems. It reduces chlorine taste and odor in water. NSF 53 certification is rare for the best inline water filters, which can reduce heavy metals such as lead.
A certification on an inline filter system can help you feel confident that it is the best available to reduce a specific contaminant. A filter that has been certified by the WQA to NSF/ANSI Standards has had its filtration claims confirmed by a third party.
This is a simple way to ensure that your money won’t be wasted on a filter that doesn’t work.
Budget
An inline water filter doesn’t require a large budget. However, depending on which filter system for ice makers you choose, you might need to invest in new filters at least every other year. Even the most expensive and the best inline ice maker filter systems won’t last forever. You’ll need to budget for the future.
Ice maker filters cost $20 to $40. Some systems have a longer life expectancy and can cost up to $50. You’ll usually spend more if you buy from a trusted brand.
Although it can be risky to pay less for an off-brand filter, many people find success using them. Don’t be discouraged by the fact that a filter may not be manufactured by a well-known brand. However, it is possible to find great deals even if your budget is tight.
How to Install Your Inline Filter
An in-line water filter can be installed easily by you. This is great if your goal is to save money and avoid the need to hire a professional. Although installation can vary depending on the inline water filter system purchased, the process is generally the same.
- Gather your materials. You will need a utility knife or a pair of scissors that can make clean cuts. A bucket, towel, and work gloves are all you will need.
- Turn off the water supply to your tap. It would make installation a mess if you don’t shut off the water supply first. Under your kitchen sink, you will find a water shutoff valve. Turn it in the opposite direction and turn off the water supply. Then turn on your faucets for any excess pressure.
- Unplug your refrigerator. If you are installing an inline water filter for your refrigerator/ice maker, you will need to unplug it and remove it from your wall.
- Install filter mounting hardware. Attach your filter mounting equipment to your wall. This job will require a drill or screwdriver. You will need a drill or a screwdriver to attach the mounting equipment to your filter. Most filters must be installed vertically. Some filters won’t work horizontally.
- Cut the water supply lines. Use a knife or pair of scissors to cut the water supply lines in the area where you want to place your inline filter. To clean the ends of your cut supply line, use a towel.
- Attach the inlet tube. Observe the body of the water filter. One side should be the inlet side and the other side the outlet side. To ensure that the tube is securely connected, push the inlet end from the water line into your water filter.
- Removing any carbon residue. Attach the inlet end to the waterline. Hold the filter at an angle, and place it over the bucket. Turn on the water supply. Wait until at least 2 gallons have passed through the filter into the bucket. Switch off the water supply.
- Attach the outlet tube. Push the outlet end from the water line into your water filter. To make sure the water line is properly connected, tug the filter onto the bracket.
- Verify that your water supply is on and off. To stop water from escaping, push the tubes deeper into the filtration system. Once you are satisfied that the system is functioning properly, plug your fridge back into the wall and push it in place. Turn on the water and taste it. It should be cleaner.
Maintenance of an Inline Filter
Your inline water filter will only need to be maintained by changing its filters. If you are unsure about the filter’s life expectancy, consult your manual. If your water quality has decreased or your flow rate has slowed, you may have to replace the filter less often.
Another easy task is to replace the filter. You will need to replace the whole system and then install a new filter following the instructions. Before you use the system, make sure to flush the filter.
FAQ About Inline Water Filters
What is an inline water filter exactly?
An inline water filter can be added to your existing water supply. An inline water filter is a good option if you have hard water, or are using well water.
Are inline water filters limited to sinks?
You can fit an inline water filter to any water supply. You can also get refrigerators with icemakers, showers and campers.
How often should I change my filter?
The brand and type of filter you choose will determine the filter that you use. Each filter has a different life expectancy, so you should take this into consideration when making a decision.
Are inline water filters compatible with iron?
Iron is a common element in water, particularly in rural areas. Some filters cannot filter iron or other metals. Make sure you get one that has been approved by the NSI and WQA. These approvals will let you know exactly what each filter can do to your water.
What is better an inline water filter than an internal refrigerator filter for a fridge?
Yes, in some ways. Although both filters provide clean water, inline filters have a longer life span than internal fridge filtration systems. An internal filter can be more difficult to fit into your system. However, an inline water filter will work in your fridge or icemaker regardless of brand.
What happens if your inline water filter is not changed?
An inline filter cartridge is limited in its ability to remove contaminants from water. Your filter will stop working after its maximum lifespan and produce less clean water. If your filter doesn’t remind you to change it, it is important to do so.
Most inline filters decrease chlorine. Why is chlorine so important?
Municipal water is treated with chlorine to make it safe for drinking. Consuming small amounts of chlorine will not cause major health problems. Many people dislike the taste of chlorine in their water or ice maker. Too much chlorine can cause health problems. Inline filters filter out the majority of chlorine, making it taste fresher and more pleasant.
What should you do if your inline filter is leaking?
A leaking filter is usually caused by an installation problem and not a fault with the cartridge. It is usually easy to fix the problem. Leakage can be caused by the water line not being pushed in deep enough. It’s best to turn off the water supply, plug in the water filter and push the water line into the filter as deep as possible. Then, switch back on the water supply, turn the water back on, and then check for leaks.
Which inline water filter is best for me?
The majority of inline filtration systems for getting drinking water are similar so the decision is largely based on your budget and the desired contaminant removal. You will see the greatest improvement in your water quality and taste if you have a good idea of what contaminants your water contains. You can choose wisely based on your annual budget when it comes to the price of your filter.
My inline filter is making my water taste strange. What could it be?
Check whether the instructions have been followed correctly and the ice maker water filtration system was flushed with water for at least 2 gallons before you use it. The funny taste you get from the filter is likely due to compressed air bubbles that have made their way into your drinking water. After a few days, the taste should disappear.
What do I need to do to clean my inline filter?
It might seem easier to clean your ice maker water filtration system by hand, but it is not recommended. After the filter’s recommended lifetime, you should throw it away. An inline water filter cannot be cleaned by running water through it. It is packed with small filtration media that traps contaminants and prevents them from escaping. You can clean the filter’s exterior with a damp cloth.
