Countertop Water Purifiers

Countertop water filters offer affordability paired with ease of use and filtration efficiency. They are a great option for those looking to reduce both physical contaminants (like silt and sediment) and chemical ones such as chlorine.


Best of all, they do so without the hassle of crawling under your sink or connecting hoses to your faucet. Many models also come with an indicator that alerts you when it’s time to change the filter.

iSpring Countertop Drinking Water Filtration System

The iSpring CKC1C is one of the best countertop water filter systems available. This model comes with a stainless steel faucet that is easy to connect to your sink. It is designed to remove chlorine, odors, and other chemicals as well as sand, silt, sediment, and rust from tap water. It also filters out harmful bacteria and parasites and improves the overall taste of the water. It’s important to note that this model does not filter out particles smaller than 5 microns, so it’s not a replacement for a reverse osmosis system.

This countertop water filter has a 3-stage filtration process that includes a coconut-based activated carbon block cartridge, which reduces chemical contaminants and pesticides. A reverse osmosis membrane then removes 99% of dissolved solids in the water, such as arsenic, lead, nitrates, sodium, and calcium, as well as other heavy metals. Lastly, an alkaline remineralization filter adds essential minerals to the water, making it healthy and taste great.

Countertop water filters are popular because they can be installed quickly and easily, and require no plumbing work. They are usually small and sit on the counter, next to your sink or kitchen tap. Many have a reservoir where clean water collects, which you can then use to fill a bottle or mug. Some have meters that show when it’s time to change the filter media, while others simply require you to follow the manufacturer’s recommended replacement schedule.

Culligan Countertop Water Filtration System

This countertop reverse osmosis system offers out-of-sight filtration with on-demand filtered water from a faucet. It uses five-stage filtration to reduce fluoride, iron, copper, and lead. With a large storage tank, this system is rated to produce up to 50 gallons per day and can easily meet the needs of most households.

Culligan also makes whole house water filters that remove sediment and scale from the entire supply of drinking water in your home.

Most countertop water filter systems require no installation or complicated piping to work, making them an easy solution for renters and homeowners. They’re generally fairly inexpensive and offer decent performance with a high-quality filter that lasts for months before needing to be replaced. They’re also small enough to fit on your countertop and can be used with standard sized kitchen taps.

Drawbacks to countertop systems include limited capacity, inability to be refilled on-demand, and sometimes slow filtration speed (which depends on the water pressure in your home as well as how thorough the filter design is). These systems can also take up counter space and may be more visible than other options.

The best countertop water filters are certified by a third party and have either WQA or NSF International certifications. This guarantees that the system meets specific quality standards. A good water filter will also have a test kit that you can use to get an idea of what exactly is in your water. It is also important to check the water quality report that your local municipality provides every year. The report will provide you with information about how much calcium and magnesium is in your water.
