What To Look For In A Water Filter for Faucet

When shopping for a faucet water filter, you need to be aware of the filtering system and its capabilities. You also need to consider capacity, convenience, and maintenance.

Filtration System

The first thing you need to look at in a faucet water filter is the filtration system. A good filtration system will remove contaminants while leaving behind beneficial minerals. Contaminants include lead, mercury, chlorine, sediment and other pollutants. The filtration systems vary in quality and price as well as in the type of material used for the filter media. The most common include activated carbon, reverse osmosis, ion exchange resins and distillation.


The second thing you need to look at when shopping for a faucet water filter is capacity. Capacity should be one of your top concerns when shopping for a new filter for your home or office. A good water filter has an easy-to-read indicator that lets you know when it’s time to change the cartridge or replace the entire unit. Some filters have a timer that tells you how long it will take before your next cartridge needs to be changed while others have an electronic readout that displays the current level of impurities in your tap water. Capacity can also be a function of your faucet’s water flow. If the tap water is very cold or hard, the cartridge will need to be changed more frequently than with hot or soft water.


The third thing you need to consider in your choice of a faucet filter is convenience. No one wants to spend all day changing cartridges or cartridges that don’t last very long as it can take quite a while and many frustrating experiences before you find the right filter for your specific home or office. Having a higher capacity unit that is easy to clean and change will go a long way towards making your life easier and less stressful.


The final thing you need to look at when choosing a faucet water filter is the maintenance required. Most of the filters on the market are very easy to install, but they are not maintenance-free. You need to check the bottle of cleaner or cartridge you use after every single filter change and ensure it’s still effective before starting to use the system again.

One of the easiest ways to improve your home’s water quality is to install a faucet filter on your kitchen taps. Not only will it eliminate lead and chloramines, but it will also reduce bacteria and other contaminants that can be present in your tap water. Most faucet filters are relatively easy to install and usually require no more than 15 minutes of your time.

Remember, installing a faucet filter is much easier than changing a cartridge. You do not need to take your sink apart or deal with low water pressure at the faucet. All you have to do is connect the unit to your faucet and install it in the dishwasher when you’re done.

FAQs about Water Filter for Faucets

1. How does a faucet filter work?

Filtered water is delivered to your tap via a diverter valve, which sits on top of the faucet and directs unfiltered water down the spout and filtered water up through the filter. When you flip the diverter valve down, unfiltered tap water flows through your faucet as normal. When it’s flipped up, the flow is diverted up through the filter.

2. Which filter is right for me?

Whether you want filtered water for drinking and cooking or just cooking, there are filters designed to meet your needs. Filters designed for drinking and cooking have a greater capacity, allowing them to produce more filtered water than those designed only for cooking. The type of contaminants you’re looking to remove plays a role in choosing a system as well. If you’re looking for basic filtration, there are standard filters that reduce chlorine taste and odor, particulates and sediment, lead and mercury. Premium filters go beyond those standards to reduce or remove additional contaminants, such as lead, cryptosporidium and total dissolved solids.

3. Relation between the filter cartridges and their performance?

The pore size of the filter medium has a significant impact on the performance of a carbon block water filter. The pore sizes are measured in microns. It’s important to understand that just because a cartridge is certified to remove certain contaminants, it may not be able to remove them all. The more pores you have on a carbon block water filter, the more contaminants it can remove. More pores also mean that fewer contaminants can pass through.

4. Can an instant hot water dispenser be used with a faucet filter?

Yes, it’s possible to use an instant hot water dispenser with a faucet mounted carbon filter. However, if the water you’re filtering is colder than room temperature, you may need to run cold water into your sink for a few seconds before you can get hot water from your dispenser. This is because carbon filters must remove some of the chlorine from the incoming water to function properly. Chlorine will evaporate at room temperature so if your incoming cold water is below room temperature, then the less chlorine there will be in the filtered water coming out of your dispenser.
