Best Countertop Water Filters

Countertop water filters use different systems of filtration, with a vast majority being micro porous filters. The filters also operate in different ways; some are fixed directly onto the faucet nozzle while some come as water pitchers. Besides purifying water, filters also help remove unpleasant tastes and odors which may be present in water. Large water pitchers come with a tank that is filled with water, which runs downstream as it is filtered. This type of water filtration system stands out from the rest because it is very efficient at eliminating harmful, disease causing microorganisms such as parasites and bacteria. The other chemical contaminants that can be eliminated using this filtration system Chlorine, radon 222 and organic solvents. Tests also show that countertop water filters have the ability to reduce the levels of nitrites, arsenic, nitrates, fluoride and harmful chemicals like mercury and lead while retaining essential minerals that the body needs to stay healthy. Here are our picks for the best countertop water filter systems:

3. APEX Alkaline

APEX Alkaline

The APEX Alkaline water filtration system is designed to offer a sophisticated, multi-stage filtration system without the installation of a complex, heavy or resource-intensive system. Unlike most filters, the APEX adds dissolved minerals back to the filtered water, which may prove a desirable option for persons who want flavorful water or are not satisfied with the taste put out by other filtration systems.

The core of the APEX is a large filtration column that takes up almost the entirety of the unit. This particular model, due to its clear sides, shows the filter in action, and also permits the user to visually observe if anything has gone wrong with the filter that necessitates its replacement. The filter is a standardized unit that is produced by many companies, which increases availability and reduces long-term running costs. The filter needs to be replaced only once every 1500 gallons, making it more than suitable for most drinking water needs.

Installation is relatively easy and will not require tools in most cases. All necessary attachment hardware is included, and the sink is still available for unfiltered use for cleaning. All components have been certified and tested by the NSF, but the final product has not been tested, nor has it been evaluated for raw effectiveness regarding heavy mineral removal. Therefore, it is not possible to say what percentage of heavy metals and other contaminants have been removed. However, the filtration system is similar in content and chemical action to most high-quality filters, and so it should be more than adequate for removing basic contaminants and improving taste.

Indeed, the primary focus of the APEX is to improve taste, not to eliminate potentially harmful microbes and chemicals, although it has the components necessary to do the latter in most cases. As such, while most taste-affecting chemicals and metals are removed, the pH is increased, and various alkaline metals are added, including calcium, magnesium, potassium, and sodium. Such alkaline additions are common in many forms of bottled water or spring water and give it the unique flavor, although it may not be preferable for everyone. Additionally, these dissolved salts make the produced water suitable only for drinking. Application of the water to fish tanks or in devices intended for use only with distilled water can leave an undesirable residue or unwanted increases in pH. This makes the APEX Alkaline suitable only for the production of drinking water where the normal tap has an unpleasant taste due to contaminants.

4. WaterChef C7000

WaterChef C7000

The WaterChef C7000 is a countertop water filtration system designed to improve the quality of tap water through the use of a “big block” style filter.

While it does not remove all contaminants and is not suitable for humidifiers, CPAP machines, and other devices that require distilled water, it is more than adequate for drinking water. Its removal of almost all metal ions significantly improves taste, especially in areas where tap water is often contaminated by rusting or degraded pipes.

Installation is easy, with no tools required to connect it to most faucets. The machine has a lifetime warranty, and other than the battery and filter no components should need to be replaced during the life of the device. It is competitively priced when compared to other units, and its large capacity should provide enough water for drinking, although it is inadequate for purposes of bathing or washing.
