Spruce Eats / Amelia Manley Bottled water is convenient, but having a ceiling filtration system at home is a much more sustainable option that can give you clean, fresh, refreshing water when you want it, without having to go to the store. We tested popular countertop filters to provide you with the best tasting water possible, and some are even certified to remove pharmaceuticals, asbestos and other contaminants. All products included are NSF certified, which is the standard to make sure the products filter exactly what they say they will.

Best Overall Sources iSpring CKC1C Amazon View at Amazon $39 View at Walmart $39 View at Home Depot $39 What we like Compact design Easy to connect Affordable unit and filter cartridges What we don’t like Reduces total dissolved solids iSpring’s compact filtration system has a Modern design that looks subtle yet elegant on any kitchen counter, whether in your home, apartment, camper or RV. The transparent filter housing allows you to see when the filter needs to be changed, but it also comes in an opaque white option. iSpring says its coconut shell carbon block filter lasts six months and removes 95 percent of chlorine, odors, sand, mud, sediment and rust. The company also claims that it is highly effective on volatile organic compounds (VOCs), such as pesticides, herbicides and industrial chemicals. The system does not reduce total dissolved solids; For this, you will need to upgrade to a reverse osmosis system. Although this product is not NSF certified, it has been tested by the Water Quality Association (WQA) to meet NSF/ANSI standards. This product is easy to install. All you have to do is remove the aerator from your faucet (if it has one), connect the diverter valve (two adapters and lock washers are included to match the internal or external threads on the faucet), and turn on the water until it. Goes clear to take out the loose carbon. Turning the diverter handle in line with the connector gives you regular tap water, while moving it perpendicular to the connector gives you filtered water for drinking directly, baking bread, use for coffee, etc. Filtration Type: Carbon CTO (Clear, Taste, Odor) | Filtered contaminants: chlorine, sand, mud, sediment, rust | Preserves minerals: Yes | Certified by: WQA | Dimensions: 9.5 x 14.5 x 16.25 inches | Warranty: 1 Year Best in Fluoride Removal AlcaPure Reverse Osmosis Countertop Water Filter at Amazon View at Amazon $489 What We Like Removes Fluoride, Chlorine Odor and Metallic Taste Reverse Osmosis Filtration No Assembly Needed We Don’t Like Filtron Only a Half Gallon At a time regardless of its size some studies suggest that high levels of fluoride in drinking water can damage teeth and weaken bones. Fortunately, there are several water filters that can remove most of the fluoride present in tap water. This model in particular does an excellent job of this, as the company claims that it removes up to 95 percent of fluoride and up to 99 percent of other contaminants from tap water. We were particularly impressed that it completely removed a heavy clear smell and a slight metallic smell from the city sent toothpaste. It also removed the bitter metallic taste of tap water, replacing it with one that is clean, fresh and light. No installation or assembly required: the filter sits on your kitchen counter and all you have to do is plug it in and load tap water at the front. It filters clean water at the top of the unit through a four-stage process, including reverse osmosis. The process takes about 15 minutes for a half-gallon of water, which in testing meant frequent refills from the unfiltered water drawer in the back of the machine. Note: The reverse osmosis membrane and filters of this device are certified by the International Association of Plumbing and Mechanical Officials (IAPMO) to NSF Standards 42 and 58, but it is not a fully NSF-certified product, according to the NSF database. This modern and stylish water filter takes up little space and counter height, measuring 9.5 x 14.5 x 16.25 inches and is on the higher end of the available products. All three filters should be changed every 12 months and the reverse osmosis membrane should be changed every two years. An LED indicator lets you know when it’s time to change them. Filtration Type: Reverse Osmosis | Filtered pollutants: chlorine, industrial chemicals, pesticides, herbicides, turbidity, VOCs, microorganisms | Preserved minerals: No | Certified by: IAPMO | Dimensions: 9.5 x 14.5 x 16.25 inches | Warranty: 1 year The Spruce Eats / Jennifer May The Spruce Eats / Jennifer May The Spruce Eats / Jennifer May The Best for Easy Installation Brondell Countertop Water Filtration System View at Amazon $130 View at Walmart $130 View at Brondell com Mineral taste No tank, connects Directly to the faucet takes minimal space that we do not like can not be compatible with all faucets Countertop water filters use incredible technology to filter tap water without having to install anything under the sink. This uses a patented three-stage nanotrap technology, which is usually only found in under-the-counter systems. It has been tested and certified by WQA in accordance with NSF/ANSI standards 42, 53 and 372 and will reduce volatile organic compounds (VOCs), chlorine and lead. During testing, we found that it also removed bad tastes and odors, including those of chlorine and minerals, leaving no noticeable odor and producing a clean taste. Measuring 3.75 x 10.5 x 13.5 inches, this model takes up little counter space, and customers agree that it looks sharp with its slim and sleek design. There are three filters included, each corresponding to a different filter stage. The first stage (composite plus filter) and third stage (carbon block filter) require replacement every six months, and the second stage (nanotrap filter) requires replacement about every 12 months. If you have a standard kitchen faucet, the Cypress simply attaches to it with the included faucet adapter. For non-standard faucets, you can buy an undercounter water connection separately. During testing, it took about 30 minutes to install the T-valve and connect the filter to the main cold water line. Once the filter is connected, there is no waiting time – just press a button and voilĂ , you have clean water.
