Best Countertop Water Filter & Best Water Treatment

It can be tough to sort through all the different models of countertop water filters on the market; there are so many of them. But, if money is not an issue, and you are just interested in making your tap water the healthiest, purest, and best tasting, no matter the price tag, then this is the place to look. Even if you aren’t looking to spend a lot of money, these water filters can provide you with a point of comparison against other models that you might be considering purchasing.

When coming up with the countertop water filters on this list, there were several important criteria that were considered. One of the most important features was certification by an independent third party organization to ensure that the filters performed as claimed. In general, these water filters are expensive and are manufactured in various places all over the world, so they might not be all that available in the United States at the moment.

Since water filters are meant to remove as many pollutants and particulates from a tap water source as possible, it was important that each of these filters cover a wide range of pollutants and particulates through their filtration methods. Most of these filters use superior technology compared to the majority of mainstream products. To top it off, a few of these models don’t just remove the pollutants in the water, but they also create positive effects on the water so that the water is healthier, purer, and tastes better than your tap water would have even if there were no pollutants in it. These filters are for cold water use only, in chlorinated public water systems unless otherwise specified.

For the best countertop water filter, don't worry about sorting through all the different brands. Our experts find the best water treatment filters from Nikken, Japin and others to fit your needs.

The Best You Can Get

  • Japin iWater Drinking System

    Anca says: Japin is an Asian company that has recently brought their amazing technology to the United States in the form of the iWater Drinking System. Japin is dedicated to environmental friendliness by ensuring that all Japin bottles and paper packaging are recyclable, and they have an internal team that focuses on reducing their impact on global warming. The product also is eco-friendly in that it produces no waste water, has zero emissions, and uses no electricity. The iWater system is extremely easy to install and can be used as a countertop model, an under sink model, or a wall mounted model. The healthy technology of the system allows the filters to eliminate pernicious materials, while still maintaining the beneficial materials in the water.

    The iWater system uses a ceramic candle, a carbon filter, and a unique HADO magnetization device. The housing is made of extremely durable stainless steel. A nice feature of the iWater system is the iMeter display (visible through the translucent blue iMeter window) that indicates the amount of water energized by the iWATER System. iWater is certified NSF/ANSI Standard 42 to remove chloramines, chlorine, taste and odor, and nominal particulate reduction, and NSF/ANSI Standard 53 to remove asbestos, chlordane, lead, mercury, MTBE, PCB, toxaphene, turbidity, cysts, and volatile organic compounds (VOCs). It has also received the Water Quality Association’s Gold Seal, which is awarded to only select filters.

  • Nikken PiMag™ Deluxe Countertop Water System

    Anca says: The Nikken PiMag™ Deluxe Countertop Water System is based on principles discovered by scientists in Japan more than 30 years ago. It replicates the environmental conditions that transform ordinary water into the “water of life.” PiMag water helps restore the natural balance of fluids that plants, animals and humans are composed of internally, for optimal health. Who could pass up the “water of life”? Using filtration and the PiMag technology, the system is able to have a reduction rate of greater than 90% for over 30 contaminants tested to date. There is a convenient and easy to use LED indicator that takes the guesswork out of filter replacement and lets you know when it is time to replace it. It is certified NSF/ANSI Standard 42 to remove chloramines, chlorine, taste and odor, and nominal particulate reduction, and NSF/ANSI Standard 53 to remove asbestos, chlordane, lead, mercury, MTBE, PCB, toxaphene, turbidity, cysts, and volatile organic compounds (VOCs).

  • Amway eSpring™ Water Purifier

    Anca says: The eSpring Water Purifier combines state of the art technology, with convenient features, and has more certifications than just about any other water filter on the market. This system was the first in-home system to combine ultraviolet light technology with a patented multi-stage carbon-block filter. A patented monitor display lets you know that the system is functioning properly and electronic "smart chips" signals when a replacement is required. The UV bulb switches on only when you turn on the tap, so water flows cold, not warmed by the UV light. Because the bulb is not on all the time, you do not waste energy.

    The eSpring Water Purifier is the first water filter to achieve 3 ANSI/NSF Certifications (Standard 42: Improves taste, odor and clarity, Standard 53: Effectively reduces health-effect contaminants like lead, mercury, pesticides, and more, and Standard 55: Controls microorganisms with UV light). On top of that, it has been awarded the WQA Gold Seal Certification. Even though the filter is greatly effective at removing the contaminants in water, it is still able to keep the beneficial minerals such as calcium, magnesium, and fluoride in your water. The product also comes with a two-year limited warranty on parts and labor, and a satisfaction guarantee.

  • Multipure MP880SC

    Anca says: The Multipure MP880SC is an all around great countertop water filter. It is extremely compact so it doesn’t take up much counter space, and is easy to install. It is certified with both NSF/ANSI Standards 42 and 53. Standard 42 certifies it can remove chloramines, chlorine, taste and odor, and nominal particulate reduction, and NSF/ANSI Standard 53 is for removal of asbestos, chlordane, lead, mercury, MTBE, PCB, toxaphene, turbidity, cysts, and volatile organic compounds (VOCs). It is a durable product since it is made out of stainless steel, and comes with a good warranty. The MP880SC’s replaceable triple-action filter has been formulated using materials that will provide the highest quality drinking water without removing the healthful, natural minerals. Multi-Pure's carbon block filters combine mechanical filtration, electrokinetic adsorption, and physical adsorption to provide the most effective contaminant reduction possible.

  • Wellness Kitchen S-III

    Anca says: The Wellness Kitchen S-III is quite the remarkable piece of technology in terms of water filtration systems. It is manufactured in Australia and uses some innovative techniques to produce one of the best countertop water filters. The S-III not only filters water, but also ionizes. This product meets standards established by the Australian National Health and Medical Research Association (NHMRC), the American Water Works Association (AWWA), and the National Sanitation Foundation (NSF). Included in the unit is an innovative digital meter that monitors water usage.

    A primary filtering process takes the water through a multi stage filtration using several carbon filters. This removes the pollutants in the water. Once that has been accomplished, the water enhancement can take place. One of the most unique features of the water enhancement is that it uses volcanic enhancement and involves all of the following filtration media: Granular coconut shell and activated carbon, SPG 28, Magnetite, Bakuhan, Tenk-Seki, Taicho, and High Gauss Magnets. All of these filters and enhancers combine to create your very own natural spring water producing unit. The filter reduces chorine, chloramines, and by-products such as tri-halomethanes, suspended solids, pesticides, volatile organic compounds (VOCs), heavy metals, and many other harmful dissolved compounds.
