The Benefits of Faucet Water Filters

Best Tap faucet Water Filters for your homeThere are many benefits to using a faucet water filter.

Healthier Water

Even though these are just water filters, not purifiers, they will produce healthier water than what usually comes out of your faucet. It doesn’t matter if you are connected to a municipal water source or a tested well, the filters will block many contaminants from entering your drinking water. Consequently, you will enjoy the benefits of filtered tap water.

Also, see our blog post on distilled vs. purified water.

Easy Installation

Some people avoid buying water filters because they’re afraid they won’t know how to install them. This is not a problem for faucet water filters. These filters are easy to install, and most people will be able to install them by themselves in under 5 minutes.

No Chlorine

It doesn’t matter which faucet water filter model you choose, it will remove the chlorine from the water. Chlorine is used as a disinfectant in municipal water filtering facilities. However, chlorine has been linked to a number of diseases in the past decade, so it would be better to avoid ingesting it.

No Foul Smell or Taste

Faucet water filters are very good at removing weird smells or tastes from the water. If you think the water coming out of your faucet has a funny taste or smell, these are the filters for you.

Blocks Usual Microorganisms

A faucet water filter will stop Giardia and Cryptosporidium from reaching your drinking water. Ingesting these microorganisms might lead to a rapid deterioration of your health. People with giardiasis might experience symptoms for up to 6 weeks.

Environmentally Friendly

Faucet water filters do not waste any water during the filtration process. They also don’t need electricity to run, so they don’t have a carbon footprint. These filters are also more environmentally friendly than buying bottled water because they don’t use plastic containers.

No Plastic

Not only will be reducing your plastic consumption good for the environment, but it will also be healthier. Not all mineral water manufacturers use food-grade plastic for their containers, so after some time, the plastic might leak into the water. Drinking this water can lead to some serious health issues.

No Nitrates and Nitrites

These filters are very efficient at removing nitrates and nitrites from your water source. These compounds are usually found in pesticides and insecticides, and they can accidentally leak into your water source. Ingesting these compounds is especially dangerous for the young and elderly.

Blocks Heavy Metals

Faucet water filters are very efficient at reducing the number of heavy metals present in your water. Heavy metals can leak into the water from the contaminated soil, but sometimes even the pipes distributing the water from the municipal source can contain some.

What Features Should I Look For In a Faucet Water Filter?

  1. Filter Change Sensor

    Faucet water filters are low-maintenance units. However, one constant maintenance operation you will need to do regularly for every filter is the filter change. Having clean filters is essential if you want to drink clean water at all times. This is why it’s important to know when to change water filters before they get blocked by filth. A filter change sensor can help with that. Some models use a sensor that will notify you when the filters approach the changing period, while others will only notify you when the filter needs immediate change. It doesn’t matter which of the sensors your filter has, as long as it has one. If you don’t choose a filter with this kind of sensor, you will have to mark every change of filters you do.

  2. Filter Longevity

    The longer your filters will last, the less frequently you will have to change them. This might not seem like a big advantage since the filter change usually doesn’t take more than 5 minutes, but it can be frustrating to have to change the filter every month. If you know you’re not very patient, it might be better to opt for a unit that needs a less frequent filter change from the start.

  3. 360-degree Swivel

    Some faucet water filters don’t swivel at all, and this might be an inconvenience when you do the dishes, especially if you use larger pots or trays. Having a filter that swivels will remove this problem altogether.

  4. Different Finishes

    Getting to pick the water filter’s finish will help you maintain the kitchen’s decor. Choose the same finish as your other appliances and fixtures, and the faucet will blend right into the kitchen’s design.

How do Tap Faucet Water Filters Work?

How Faucet Water Filters WorkBefore we start explaining how faucet filters work, we have to make sure you’re aware of something. Faucet water filters filter the water, but they do not purify it. Many people consider the two terms synonymous, but they’re actually not the same thing.

Just to be clear, water filters like these produce filtered water, while reverse osmosis systems produce pure water. The difference between the two is notable, but here is a quick explanation of what’s different.

When you use a water purifier, you don’t have to use it on treated water. You can simply use it on untested well water, or even on the water you previously know to be contaminated. Water purifiers like reverse osmosis systems will remove up to 99% of the contaminants in the water. Actually, just to be called a water purifying system, a unit has to be capable of removing at least 95% of the contaminants.

Water filters shouldn’t be used on highly contaminated or untreated water sources because they don’t work that way. When you use a water filter like a faucet water filter system, you actually improve the water’s quality by up to 20%. This automatically means the water will be healthier than it was before the filtration, but it doesn’t mean it will be good for you. A highly contaminated water source might still be dangerous for your health even if you filter it.

Faucet water filters usually rely on a cartridge filter. The cartridge has more components that work together to filter out the contaminants in the water. While there might be some differences between models made by various manufacturers, most of them employ the same components and most water filters work in a similar way.

Sediment Removal

This is the first step in the filtration process, and it’s usually done with the help of a non-woven screen wrapped around the cartridge. The screen is specially designed to stop large and small particles like rust, dirt, debris, and sand.

Activated Carbon Block

Now that the water is mostly clear of any sediment and rust, it reaches the activated carbon block. The activated carbon has a porous surface, filled with nooks and crannies. When the water flows through the block, the contaminants in the water are trapped in these crannies through a process called adsorption. Once in a while, the porous surface of the activated carbon gets filled with contaminants so its efficiency will drop. This is why you should always make sure you use clean filters.

Most manufacturers nowadays use treated activated carbon for their cartridges. This means that another substance is impregnated into the carbon to give it some particular features. Sometimes silver is added to kill off any fungi or bacteria that might escape the carbon filter. Other times some other chemicals might be used, but their purpose would be similar.

Chemical Removal

The next step in the filtration process ensures that the chemical contamination level is reduced. Activated carbon filters are very good at removing usual contaminants like chlorine, but they can’t filter out chemicals like heavy metals or even magnesium and calcium. This is why most manufacturers make sure this filter takes out other contaminants that might find their way into your water source, like lead, mercury, or nitrites and nitrates. This filter also blocks out bad odors and tastes. The amount of time the water stays in contact with the cartridge filter determines how many contaminants are trapped. If the water has longer contact with the activated carbon filter, more contaminants will be trapped in the porous surface of the filter. This is why many faucet water filters will produce slower water flow.

best faucet water filtersFaucet Water Filter Installation

Even though they are produced by different manufacturers, most faucet water filters have a similar installation process. Before you begin the installation, make sure you have an adjustable wrench and some Teflon tape close at hand. Most faucet water filters come with all the necessary components for the installation, and some of them will also come with Teflon tape, but it’s better to be prepared. Here’s how you install a faucet water filter.

  1. Remove the faucet’s aerator. The aerator might be very tightly screwed on, so make sure you use the adjustable wrench if you can’t twist it off by hand.
  2. Put the original aerator on top of the inserts that come in the water filter’s box to make sure you find the right one for your faucet.
  3. Screw the new insert aerator on the faucet.
  4. Mount the faucet water filter on the new insert
  5. If the filter cartridge is not pre-assembled, insert it in the filter now.
  6. Turn on the water and let it running for at least 10 minutes before you taste the water.
  7. This will allow the filter to activate.
  8. Check for leaks. If there aren’t any, you’re all done. If anything is leaking, try fixing it by applying some Teflon tape.

Faucet Water Filter Cleaning & Replacement

Faucet Water Filters ReviewsChanging the filter is done differently depending on the model and manufacturer. However, most of the time this operation shouldn’t take you more than 5 minutes.

If you choose a faucet water filter that uses a filter change sensor, you should respect its indication and change its filters appropriately. Some manufacturers will also remind you via mail when it’s time to change the filters. If your faucet water filter doesn’t have a filter change indicator, you should always mark the date you changed the filters on your calendar. Most water filters come with a capacity indicator, so you know that it should last for about 100, 200, or more gallons but you don’t know how long that means.

On average, an American household would consume up to 2 gallons of drinking water per person per day. So if you live in a household of three, that means 6 gallons per day. This means you will have to change a water filter with a capacity of 200 gallons roughly once every 30 days. This period might vary according to your consumption. You may also want to check out our top picks of whole house water filters.

If you notice limescale deposits on your faucet water filter, you can clean them using a clean rag and some vinegar or lime/lemon juice. Just fill a bowl of water with a mix of 1/2 water + 1/2 vinegar or lemon juice, dip the rag in the mix, and use it to remove the limescale.

FAQ’s About Faucet Water Filters

  1. What should I do with the used filters?
    You should recycle the filters. Some manufacturers will send you a return shipping label so you can send them the used filter for recycling. If your filter’s manufacturer doesn’t offer this kind of service, look for a recycling campaign in your area.
  2. How often do I have to change the filters?
    If your faucet water filter has a filter change indicator, you should follow its instructions. If it doesn’t, you should always keep track of how often you change the filters and change them accordingly. You should calculate the amount of water you filter in the first week of using the filter and use that as a reference so you can calculate how much water is filtered each week.
  3. Does my water filter remove limescale?
    Each water filter is different, but usually, faucet water filters do not remove the calcium and magnesium from the water. Since these are the main components of limescale buildup, the answer is no.

Wrap Up

Faucet water filters are nowadays very effective at blocking and removing different contaminants from your water source. Some models are so technologically advanced that they remove more than 70 different contaminants, a thing possible only when using reverse osmosis systems in the past.

Unlike other filtration systems, these models do not produce wastewater, which makes them cheaper to use, and more environmentally friendly. Their good filtering capacity and cheap price make them very valuable units.

The best tap faucet water filters will remove most of the contaminants in your water, producing better-tasting water, similar to that of bottled water.
