How Do Faucet Water Filter Systems Work?
Before we dive head-first into the intricacies and mechanics of water filter systems, there is something else we would like to divert your attention towards. Faucet water filter systems only filter water; they don’t purify it. Most people consider the two terms synonymous, but they’re not the same thing.
Just to be clear, water filtration systems produce filtered water, but even reverse osmosis systems in the past did the same thing. The difference between both is notable, but here is a quick explanation of what’s different between them.
When you’re using a water purifier, you don’t need to use it for treated water. You can simply use it for untested water or water you suspect is contaminated. Water purifiers are similar to reverse osmosis systems, as they can easily remove up to 99% of the contaminants in the water. To be called a water purifying or filtration system, the unit must be capable of removing around 95% of the contaminants.
Water filters shouldn’t be used on highly contaminated or untreated water sources as they don’t work that way. Whenever you’re using a water filter such as a faucet water filter system, you can improve the quality of the water by nearly 20%.
That automatically means the water is going to be healthier than it was before filtration, but it doesn’t mean it is going to be good for you. A highly contaminated water source may still be dangerous for your health, even if you have filtered it.
The Mechanics of Faucet Water Filters
Faucet water filters tend to rely on cartridge filters, but the cartridge has a lot more components that will work together to filter out the contaminants in the water.
There are going to be major differences between the models made by different manufacturers, but most of them employ the same components that end up working in the same way.
The first step in the filtration process is generally done with the help of a non-woven screen that is wrapped around the cartridge. That screen is specially designed to stop large and small particles such as debris, dirt, rust, and sand.
Activated Carbon Block
After the water has been cleared of any rust and sediment, it will reach the activated carbon block, which is a porous surface that is filled with nooks and crannies. When the water flows through the block, the contaminants in the water are trapped in the crannies through a process known as absorption.
Once in a while, the porous surface of the activated carbon will get filled with contaminants, so its efficiency will drop. That’s why you should always ensure that you use clean filters.
Most manufacturers nowadays tend to use treated activated carbon for their cartridges, which means that another substance will be impregnated into the carbon to give it different features. Silver may sometimes be added to kill off any bacteria and fungi that may escape the carbon filter. At other times, some chemicals may be used, but their purpose is going to be the same.
The next step is going to be in the filtration process that ensures the chemical contamination level will be reduced. These activated carbon filters are great at removing usual contaminants such as chlorine, but they can’t filter out chemicals such as heavy metals like calcium and magnesium.
That’s why most manufacturers ensure that this filter removes the contaminants that may find their way into your water source such as, nitrites, lead, nitrates, or mercury. That filter also blocks out bad tastes and odors, and the amount of time the water stays in contact with the cartridge filter will determine how many contaminants are trapped inside it.
If the water remains in contact with the activated carbon filter, more contaminants will be trapped in the porous surface of the filter. That’s why most faucet water filters tend to produce slower water flow.
The Advantages of Faucet Water Filters
Everyone deserves to drink clean water, and there are several benefits to using faucet water filters, which we are inclined to share right here.
Blocks Heavy Metals
Faucet water filtration systems are extremely efficient at reducing the number of heavy metals that are present in your water. These heavy metals can start leaking into the water from the contaminated soil and can sometimes even get into the pipes distributing water from the municipal source that contains it.
No Nitrates and Nitrites
These filters are not only efficient at removing nitrites and nitrates from the water source, but the compounds found in the insecticides and pesticides can start leaking into the water source. Ingesting these compounds can be dangerous for the elderly and the young as well.
Not only is reducing your plastic consumption good for the environment, but it is also healthier as well. Not every mineral water manufacturer uses food-grade plastic for their containers, so after some time, the plastic may start leaking into the water. Drinking that water can also lead to some serious health problems over time.
Faucet water filters don’t waste any water during the filtration process, and they also don’t need electricity to run, so they don’t have any carbon footprint. These filters are more environmentally-friendly than buying bottled water as they don’t use plastic containers.
Blocks Usual Microorganisms
A faucet water filter is going to stop Cryptosporidium and Giardia from reaching your drinking water, and ingesting these microorganisms may result in a rapid deterioration of your health. People with giardiasis may start experiencing symptoms that will last for up to 6 weeks.
No Foul Taste or Smell
Faucet water filters are extremely good at removing weird tastes or smells from the water source. If you think that the water coming out from your faucet has a funny smell or taste, the filters are for you.
It doesn’t matter what faucet water filter model you’ve chosen, they will remove the chlorine from the water. Chlorine is a disinfectant in municipal water filtering facilities, and it has been linked to numerous diseases over the past decade.
Most people avoid buying water filters because they’re afraid they wouldn’t know how to install them. That’s not a problem for faucet water filters as they are easier to install, and most people can easily install them themselves in 5 minutes.
We saved the most obvious benefit for last, and even though these are only water filters, not purifiers, they will start producing healthier water than what generally comes out of your faucet.
It doesn’t matter if you’re connected to a municipal water source or a tested well, the filters are going to block most contaminants from entering your drinking water.
Buying Guide for Faucet Water Filters
Just because most faucet water filters tend to work similarly, it doesn’t mean they will be built in the same manner. Most of them have features that are vastly different from the res, but how do you know what features are going to be good for you? That’s a riddle we’ll solve right here:
The longer your filters are going to last, the less frequently you’ll have to change them. That may seem like a big advantage as the filter change generally shouldn’t take you more than 5 minutes, but it can still irritate you that you need to change a filter every month.
If you know that you don’t have the patience, it may be better to choose a unit that requires a less frequent filter change from the beginning.
Filter Change Sensitivity
Faucet water filters are low-maintenance units, but one constant maintenance operation you must do regularly for every filter is filter change. Having clean filters is essential if you only want to drink clean water at all times. That’s why you must change the filters before they are blocked by filth.
A filter change sensor will help you with that, but most models use a sensor that will notify you when the filters approach the changing period. However, others are only going to notify you when the filter requires immediate change. It doesn’t matter what kind of sensor your filter has, and if you don’t want to choose a filter with this kind of sensor, you’ll be marking every change of filter manually.
Getting to pick the water filter’s finish is going to help you maintain the décor of your kitchen. You should choose the same pattern and finish as your other fixtures and appliances, while the faucet is going to blend right into the design of your kitchen.
Most faucet water filters won’t swivel at all, and that may prove to be an inconvenience, especially when you do the dishes. If you’ve got larger trays or pots. Having a filter that swivels is only going to remove that problem completely.
Faucet Water Filter Installation
Even though there are different manufacturers producing faucet water filters, most of them have the same installation process. Before you can start the installation process, you should ensure that you have an adjustable wrench, along with some Teflon tape close at hand.
Most faucet water filters come with necessary components for the installation, and some of them come with Teflon tape, but it’s best to be prepared. Here’s how you can install a faucet water filter:
- Remove the aerator of the faucet. That aerator is going to be tightly screwed on, so ensure that you use the adjustable wrench if you can’t twist it off by your hand.
- Now place the original aerator over the inserts that come in the water filter’s box to ensure that you find the right one.
- Now screw the new aerator on the faucet.
- You can then mount the faucet water filter over the new insert.
- If the filter cartridge hasn’t been pre-assembled, you can insert it into the filter.
- Turn on the water and let it run for around 10 minutes before you taste the water.
- That will allow you to use the filter to activate.
- Check for any leaks, and if there aren’t any, you’re all done. If anything is leaking, you should try fixing it by applying some Teflon tape over it.
Faucet Water Filter Cleaning & Replacement
Changing the faucet water filter is going to be done differently, which depends on the manufacturer and the model. However, this operation shouldn’t take you more than 5 minutes. If you’ve selected a faucet water filter that uses a filter change sensor, you should acknowledge what it is indicating and change the filters appropriately.
Most manufacturers will remind you through mail when it is going to be time to change the filters. If your faucet water filter doesn’t have a filter change indicator, you can always mark the date you changed the filters on your calendar. Most water filters come with a capacity indicator, so you should know that it lasts for about 100, 200, or more gallons, but you don’t know how long that means.
On average, an American household should consume up to 2 gallons of drinking water per person per day. So, if you’re living in a household of three individuals, that would amount to 6 gallons per day. That means you will need to change the water filter with a capacity of 200 gallons roughly once every 30 days, and this period may change depending on your consumption.
If you notice any limescale deposits on the faucet water filter, you can start cleaning them by using a clean rag and some vinegar or lime/lemon juice. All you need to do is fill a bowl of water with a mix of ½ water + ½ vinegar or lemon juice, dip the rag in the mix, and then use it to remove the limescale.
Frequently Asked Questions – FAQs about Faucet Water Filters
We understand that not everyone is going to understand how faucet water filtration systems work and how they should go about setting them up. That’s the reason why we have decided to answer some of the most frequently asked questions about faucet water filters. Here are the top ones:
- Does my water filter eliminate limescale?
Every water filtration system is different, but usually, faucet water filters don’t remove the calcium and magnesium from the water. As these are the main components of limescale buildup, the straight answer is “no, it doesn’t.”
- What should I do with the used filters?
You should be recycling the filters, and most manufacturers will send you a return shipping label so that you may send them the used filter for recycling. If your filter’s manufacturer doesn’t provide you with this kind of service, you should look for a recycling campaign in your area.
- How often do I have to change the filters?
If your faucet water filter has a filter change indicator, you should be following its instructions. If it doesn’t have that, you should always keep track of how often you are changing the filters and change them accordingly.
You should also calculate the amount of water that you are filtering in the first week of using the filter and then use that as a reference so you can calculate how much water is filtered every week.
Nowadays, faucet water filters are extremely effective at removing and blocking different contaminants from your water source. Most models are so technologically advanced that they remove more than 70 contaminants, which was only possible through the reverse osmosis system in the past.
Unlike most other filtration systems, these models won’t produce wastewater, which only makes them cheaper to use and more environmentally friendly. Their affordable price and good filtering capacity make them extremely valuable units.
