The Few Steps to Your New Perfect Water Filter
There are several things you need to look for when selecting the next inline water filter. We understand choosing an inline water filter might look like a lot harder task than initially planned, especially with so many good choices like the one above. Starting from simple filters up to ones that need fully pre-installed systems – we are here to assist you.
We will go through each step that you need to take and will add a few key facts that should be of help when bringing your decision. But before we jump with all those filter types, if you are curious to learn more about water purification and its importance, you can read and learn here.
Let’s Start with the Basics
Simply put, the inline water filter represents a filter that is attached to the water system whose job is to purify the water. Usually positioned under the sink, it isn’t taking a lot of space. As the inline water filter is installed directly in the main water line, effective water filtering gives safer and cleaner water for the whole family.
Moreover, the filters improve the water’s taste smell by removing chlorine and other water substances and chemicals. Plus, inline water filters offer great versatility. This is due to their compatibility to be installed to additional water lines from which refrigerators, washing machines, and other water-needed appliances can use clean water.
How Does Your Filter Work
As it is attached directly to the main water line, any inline water filter offers a direct and effective way of filtering out and removing various toxins and foreign substances from the water supply.
After installation, the filter will start working immediately. Like all water filters, the inline water filter also does mechanical and chemical filtration stages.
The first stage is focused on particle barrier use. Based on the type of filter, it can remove numerous particles, toxins, chemicals, or other impurities in your water. With this, you will immediately get cleaner water.
The second stage is the chemical filtration process, which is also the most important one. As any tap water has a lot of chemicals and other substances that can turn out to be dangerous to our health, filtration of this nature is a must. Contracting any diseases and sickness is very limited after the filtration process is over.
The chemical filtration stage is where the improvement of the water taste and smell happens. Additionally, the water’s cleanliness and toxicity levels are being checked as well. During this stage, based on the filter, there is effective filtering and removal of various contaminants, going from viruses and bacteria up to volatile organic chemicals, toxins and substances.
And if your curiosity asks for more, you can check this quick video on how you can install inline filters.
Types of Filters
As you can see from our list of inline water filters, there are many different types and options. And the first thing you need to be sure of before choosing one is to know where the filter will be installed.
Are you looking for cleaner ice coming out of the ice maker? Or do you want clean sink water to drink and clean with? You may have an existing water purification system that needs filters.
As you can see, These are many things that you should consider before making that decision. Here are a few examples of inline filter types:
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.
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.
Granular filters emphasize a blend of different filter media that target a broad range of chemicals and substances efficiently. With different-sized pores, this filter can trap and filter out a lot of particles from your water supply.
Specific Filter for Existing Water Systems
There is a range of home water purifying systems you can find on the market. If you have one of those, make sure you find the filter that works for that specific type. Otherwise, you would just waste your money and add to your frustration.
Refrigerator Inline Water Filters
If you have a refrigerator with a water line attached or an ice maker, you may want to look at adding an inline water filter. Most refrigerators with water lines have an included filter for the drinking water portion, but not all of them.
Under Sink Inline Water Filters
Having clean sink water is one of the most important things to me. For drinking water or washing dishes, it is invaluable. If you want to take a look at what Reddit thinks on what are the best options out there, please check our guide here.
Pay Attention To The Filter’s Capacity And Predicted Lifeline
When you start with your search for the right inline filter, it is expected for you to have questions that you will want to find the answers to before the final decision.
In our opinion, two of the key questions you should always ask need to be connected with the filter’s predicted lifetime, and how many gallons of water can you pump through it before it would be time for a replacement?
Questions like these will already give you the idea of what you are buying. Every filter has an expected lifetime, or also known as a universal time frame. This is the expected time the producer thinks will be needed for a new filter.
However, you know your family the best. The true lifetime will vary from one family to another. It all depends on how much water is being used, or in some cases, how hard the water is in that region.
For example, if you are a couple, or you have a small family, the water consumption will be smaller compared to a bigger family of 5 or 6 people. The life of the filter will be extended, as you will not be using it so often.
You will also need to know how many gallons of water the filter can process before it is time to be changed. And even if the filter has a declaration which says, “6 Month Filter Life,” those 6 months will be a total guess, as again, that might not be the case for your family.
Whenever you can, have an extra water testing kit on hand. You will allow you to test your water and know exactly when your filter is no longer doing its job.
Frequently Asked Questions
What Exactly is an Inline Water Filter?
An inline water filter is a water filtration device that is added to your existing water line.
Why Would I Need an Inline Water Filter?
If you have hard water or are dealing with a well water supply, an inline water filter can clean and purify your water.
Do Inline Water Filters Only Work With Sinks?
No, you can install an inline water filter into nearly any water supply. Refrigerators with icemakers, showers, campers, and RVs, too
How to Maintain and Clean Inline Filters?
Depending on the best inline water you bought, the manufacturer might have specific directions on how to care and clean it. For some models, they don’t need disassembly for cleaning because it is with a filter element that can flush clean in a minute without tools required.
It also does not need to turn off the water supply to clean the filter. For more guidance, you must check the instruction manual that comes with the filter you bought.
How Long do Inline Water Filters Last?
There is no specific answer to this question. The filter’s longevity may depend on certain factors, including water consumption or condition. Some filters may need replacement every year. Nevertheless, you must check for the filter every six months to see if it needs a replacement for optimal function.
Do Inline Water Filters Work With Iron?
Iron is a common element found in water, especially in rural areas. Not all filters can filter iron and other metals, so look for one that is approved by NSI and the WQA. These approvals will tell you exactly what each filter can remove from your water.
Will Any Water Filter that Removes Chlorine also Take Out Trihalomethanes?
No, not all water filters that are certified to reduce chlorine can also remove trihalomethanes. Chlorine is relatively easy to remove from water. But chlorine that has interacted with organic material to form trihalomethanes, and therefore has assumed a different molecular structure than that of chlorine, is extremely difficult to remove.
The only way to be confident that a water filter actually will remove trihalomethanes is to check with NSF or another recognized certifying authority to verify the specific contaminants the product has been certified to remove.
Which Water Filter Removes the Most Contaminants?
It depends on the type of the best inline water you have chosen. Some are selective, and the meaning is only for removing specific contaminants in the water. To get started, you can compare the items that we’ve featured earlier for reference.
Why is NSF Certification Important?
NSF International is an internationally recognized, not-for-profit, third-party testing organization that tests and certifies products to ensure they meet strict public health standards. Certified water filtration products are tested to verify that they meet certain standards for health and aesthetics.
The result for the customer is full confidence in the product’s performance based upon independent verification that the product will do precisely what the literature says it will do.
Certification by NSF® assures the consumer that:
- Claims of contaminant reduction are true.
- The system does not add anything harmful to the water.
- The system is structurally sound.
- Advertising, literature, and labeling are not misleading.
- Materials and manufacturing processes do not change.
To ensure that manufacturers continue to meet these requirements, NSF® conducts unannounced inspections of manufacturing facilities at least once a year.
We know there is a lot of information to take when deciding the best inline water filter for your situation. But remember one thing, it is your situation, so what may be best for you may not be the best for your friends or parents.
