Staying properly hydrated has many health benefits. Daily water consumption promotes cardiovascular health, enhances skin’s elasticity, regulates body temperature, reduces dry mouth, and eliminates waste from the body. Having access to safe, decontaminated water right from the kitchen tap can help make it easier to meet your body’s need for hydration.
Countertop water filters are nonpermanent appliances that typically are placed on the counter adjacent to the sink to remove contaminants, such as chemicals, parasites, and bacteria, from tap water. Countertop models are often preferred because they’re lightweight, relatively easy to install, and don’t require enormous amounts of space for operation. Moreover, water filters help reduce plastic waste due to bottled water purchasing.

What to Consider When Buying a Countertop Water Filter
Before you can determine which is the best countertop water filter for your home, learn about the potential contaminants in your water supply and how best to eliminate them. Many companies offer free water analysis to help you pinpoint the specific compounds or particles in your water to filter from the tap water. Consider a few other characteristics when purchasing a countertop water filter to keep your family safe and hydrated.
Types of Countertop Water Filters
The two types of countertop water filters are water filter pitchers and faucet filters. Understand the pros and cons of each when shopping for the best countertop water filter for your kitchen. Each kind of filter has unique characteristics for storage, filtration volume, and water decontamination.
Water Filter Pitcher
Water filter pitchers help make water filtration easy and relatively affordable. They don’t need to be connected to the faucet and can be stored anywhere—on the counter or in the fridge. Additionally, they work well in office and dorm settings. Their only drawback is that they may need frequent refilling, depending on your household consumption. Replacing the filter monthly is typically recommended. Some pitchers display filter life to let you know when the filter is near the end of its life. To maintain your pitcher, wash it and all its components by hand every week.
A countertop water filter system, which is also called a point-of-use water filtration system, attaches directly to the faucet, usually to the faucet’s aerator. Faucet filters are designed to save space while delivering on-demand filtered drinking water. They use filtration materials like activated carbon to eliminate contaminants, and they typically take minutes to install. Along with replacing the filter, faucet filters require some periodic maintenance.
The size of the water filter is proportional to its filtration capacity. To determine which size will work for your home’s needs, consider the number of people who will be drinking the water and the amount of countertop space you have in relation to the unit’s footprint. Also don’t forget that the water filter must be next to the sink.
Filtration capacity refers to the filter’s life: the number of gallons of water the filter can effectively process and the length of time the filter will last. Not all filters can clean the same contaminants, and some models may remove beneficial minerals, too. Some of the more common contaminants removed from water are chlorine, fluoride, and VOCs. Before purchasing a filter, have the water tested to find out which contaminants are present in your water supply and the ones that are most important to eliminate.
Filter Maintenance Requirements
At some point, the filter on every water filter must be changed. The filter’s lifespan correlates directly to the model; every filter’s capabilities are different. Some have a short life, such as one or two months, while others last a long time, even a year or more. Before committing to a particular countertop water filter, consider the cost and frequency of replacing the filter to determine the overall cost of keeping the filter functioning effectively.
Ease of Use
Countertop water filters are easy to use. Once the filter is installed at the faucet, using the filter is as easy as turning on the water and filling the drinking glass or bottle. Filtration occurs in real time as the water passes through the filter. Because they operate directly at the water source and filter immediately, countertop water filters are more convenient than filter pitchers because there is no need to refill a container or wait for filtration.
When using a water filter, the taste of the water often changes subtly. Unchlorinated water tastes different from water directly from the tap. Some filters remove beneficial minerals from tap water, which could also alter the water’s taste and even change how the water feels. Look for a filtration system that either maintains or replaces essential minerals like magnesium and potassium.
Because not all filters are the same, some filter manufacturers have their filtration capabilities certified by the National Sanitation Foundation International (NSF International) or the American National Standards Institute (ANSI). The purpose of certification is to verify which contaminants a filter can remove from water. The two standards awarded are Standard 42 for Aesthetic Effects and Standard 53 for Health Effects. The standards also are reported along with a classification that defines the percentage or range of each contaminant it can remove.
The Advantages of Owning a Countertop Water Filter
Since the human body is composed of more than 60 percent water, it requires adequate water intake to function and fight infection. Tap water often includes contaminants and, at times, bacteria, which can cause health issues. Owning a countertop water filter can provide fresh-tasting, chemical-free water while protecting the environment from plastic waste.
A few advantages of owning a countertop water filter include:
- Decontamination: Filters purify water from harmful chemicals, sediments, bacteria, and parasites that affect quality and taste.
- Waste reduction: Water filters enable you to have pure drinking water without having to buy bottled water, minimizing the amount of plastics in the environment.
- Health benefits: Removing contaminants from drinking water can enhance immunity and reduce the ill effects that some contaminants are linked to.
Installing a countertop water filter is relatively easy. Here are a few common questions and answers regarding countertop water filter use.
Q. How does a countertop water filter work?
Water filters work by using a filtration mechanism to capture organisms and chemicals. A fabricated surface traps the larger contaminants, while a compound like activated carbon works as a magnet to trap smaller contaminants.
Q. How do you install a countertop water filter?
Use the hardware included with the filtration system to attach the filter to the faucet’s aerator. Though this may get in the way of the faucet’s water flow, it can provide enough water for drinking or cooking.
Q. Do countertop water filters work for all kitchen faucets?
Countertop water filters do not work with every type of kitchen faucet. Specifically, more modern designs and detachable faucets with spray nozzles may be incompatible with countertop water filters.
Q. What common contaminants does a countertop water filter remove?
Most filters can remove chlorine, fluoride, bacteria, and parasites. To know exactly which contaminants a specific filter can remove or reduce, consult the manufacturer’s information regarding filter certification.
Q. Can bacteria grow in my countertop water filter?
Yes, bacteria can grow in your countertop filter, so it’s a good idea to flush the faucet for about 20 seconds after turning on the water and then for an additional 5 to 10 seconds to filter and flush out any bacteria that may be lingering in the faucet.
