Why Use Faucet Water Filters
This type of filter is designed as a purification system for hard water where it removes contaminants and improve the quality of water. However, the number of contaminants that a filter can handle will depend on its efficiency and the degree of water hardness. You will also find water filter pitchers that serve the same purpose but in a compact form. Generally, less than 10 percent of the contaminants (harsh chemicals, pathogens, and sediments) flow through the faucet when you install these fixtures. To achieve contaminant-free water, you'll need to use more water filters.
Hard water is a common health hazard and it deteriorates personal hygiene. Health safety is a concern for homeowners that can't stand the sight of hard water. Every family deserves germ-free water for bathing and drinking, hence the need to filter water. Without going through the hassle of installing complicated systems, there are models that can be installed by anyone. Usually, when unfiltered water goes through your city's municipal underground pipes, the carry residues and harsh chemicals from the facility.
However, you are sure to have soft water running through your tap after installing small and high-quality water filters. They work with different layers of filtration media (mesh or activated carbon) that provide physical and chemical functions. As the hard water goes through their screens, they remove contaminants from the water source. So, the multi-stage filtration process ensures clean water supply when you turn on the faucet. Usually, the layer of compressed activated carbon in the faucet water filter is small but efficient. It's composed of lignite, charcoal, nut shells, wood, and other materials.
The porous layer of activated carbon is a chemical filtration process that's effective at killing bacteria. It ensures the removal of over 90% of mercury and chlorine from hard water. Apart from replaceable cartridges, the manufacturers also produce filters for reverse osmosis faucets that have an air gap. Unlike filters that need owners to replace cartridges, this type comes with an ultra-fine membrane that's made from acetate. These types are durable and last a couple of years.
Things to Consider When Buying These Filters
Regardless of your hectic lifestyle or busy schedule, you need to ensure that healthy water runs through your faucet at all times. Here are the fundamental factors to consider when buying your preferred type.
1. Style & Finish
Ergonomics is important because eye-catching yet efficient models sell faster than those with plain designs. As faucet water filters come in different styles and finishes, they can help enhance the beauty of your bathroom and kitchen to a great extent. So, it's a smart decision to choose a finish that blends well with your appliances, fixtures, and the interior decoration of your space.
2. Filter Replacement Sensor
You might need an alert system to help you keep track of its usage. Usually, faucet filters require very little maintenance and simple installation. Also, these sensors can prevent you from over-using the filtration systems.
Most high-end models have green LED light sensors that indicate proper working conditions. Also, the light might turn to yellow or red (depending on the specification) when you need to replace the cartridge or filter. When it reaches its maximum capacity, you'll notice the absence of soft water from your faucet.
Few of the today's models use day-counting sensors. As the name implies, these sensors track your usage from the last date of your filter's cartridge replacement. Simply reset the counter each time you install a new cartridge and wait for the sensor to alert you when it’s due the cartridge is due for replacement.
3. Type & Size
Depending on the space around the waterline of your kitchen sink or bathroom faucet, choose the size that can work well. There are different shapes and sizes, but these features don't make faucet filters effective.
It's common to see faucet filters with built-in activated carbon filtration systems. It includes shafts from coconut shells, charcoal, and other layers of that help to trap sediments. Carbon filters are porous materials that collect impurities as unfiltered water passes through them.
A system that supports reverse osmosis and conventional carbon filtration is a great unit. Usually, the ultra-fine membrane of reverse osmosis filters withstands the sieving of high-pressure unfiltered water. Also, they are made of acetate and they don't need regular replacements like the conventional carbon activated filters.
Generally, filters for kitchen faucets are installed along water lines and above the sink. However, the large units are often placed under countertops for convenience. Regardless of their position, these types are ideal when there's limited space in your kitchen.
Depending on the manufacturer and manufacturing quality, our recommended filtering capacity for cartridges ranges between 100 to 400 gallons of water. It means they can purify hard water of the maximum volume specified on the label before their replacement time. Replacing filters doesn't take longer than ten minutes, but you shouldn't forget to change when necessary. Additionally, you should get filters with built-in gauges to determine the volume of gallons filtered.
The lifespan of a faucet water purifier usually depends on its design. It's important for manufacturers to test cartridges before their products are sent to retail shelves. While the regular ones last for a few months, the high-end choices can serve for two to three years. The lifespan of filters ensures the quality of water from your faucet before their replacement dates. You shouldn't be surprised to see contaminated water from your tap or spout if you fail to change the cartridges on time.
The ease of installation is an important factor to consider. You'll need simple tools like the adjustable wrench to adjust your faucet's aerator. Generally, the good ones are easy to install and sometimes you may not need any tools at all.
On average, the cost of a good faucet water filter is between $15 to $60. They are not really that expensive but can save you a lot of money that you might otherwise spend on bottled water.
There are certain procedures for installing different types of faucet water filtration systems, whether for shower heads or taps . This is necessary so you don't have any issues in near future, like a slow filter rate or the filter leaking for some reason. Most manufacturers have their unique designs like the one-click installation method. Usually, the whole process takes less than 10 minutes. Sometimes, you may need a pair of plastic pliers for the installation; but generally, the process is easy with all the necessary components. Few installation processes involve the use of Teflon tapes.
- Unscrew the faucet’s aerator with an adjustable wrench because the original plumbing installation might be very tight because of your faucet’s age. Also, don't discard the washers in the faucet after unscrewing it. You might not need the washers immediately.
- Clean the threading under your tap's aerator because the source of hard water might have caused build-up around the aerator. You can apply vinegar while cleaning the surface.
- Find the right adaptor for your faucet's aerator; you'll know if they both align. Sometimes, standard male faucets attach to water filters directly. You'll only need adaptors when with female faucets.
- It's time to attach the filter cartridge if it's not pre-assembled. Watch out for the point of attachment when of your filter housing and the faucet. You'll hear a 'clicking' sound that confirms it’s twisted in place properly. Then, insert the filter cartridge into the case, after attaching the mounting collar.
- Allow the faucet mount run its first filtration run for at least 10 minutes before drinking (or using) the water.
- The right time to check for leaks is when the filter is active. By applying Teflon tape around the threads, you'll ensure zero leaks in your kitchen's faucet filter attachment point.
Cleaning & Maintenance
One of the easiest parts to maintain in the water filter is the outside material. By cleaning the exterior surface with vinegar, it ensures effective removal of fingerprints or smudges. Here are the essential maintenance tips that will ensure germ-free drinking water without any clogs or other issues.
- When installing or replacing (screwing or unscrewing) filter cartridges, care must be taken not to over-tighten the threaded plastic portion.
- Avoid the use of harsh chemicals on the surface of a filter change sensor's indicator. The LED light is a bright display, and harsh chemicals from cleaning reagents can dull their brightness.
- Ensure to replace your filter cartridge one at a time, and adhere to the indication on your filtration device. Also, water consumption pattern may vary accordingly. So, the time to replace your filter cartridge depends on consumption.
- Use a piece of clean rag, and few portions of vinegar (or lemon juice) to clear limescale deposits from faucet water filters. Additionally, you can dilute the vinegar (or juice) with a quarter cup of water and vinegar respectively.
