Shop the best water filtration systems that remove chemicals, minerals, and more

Do you know what’s in your tap water? Depending on where you live you might find fluoride, heavy metals, volatile organic compounds, and more. If you don’t want those in your drinking water, you have a couple of options. First, use exclusively bottled water, which is expensive and bad for the environment. Or, second, you can invest in a water filter.

Fortunately, there are a wide range of water filtration systems on the market from pitchers you keep in the fridge to reverse osmosis systems you’ll...MORE want to have professionally installed. Depending on your space and whether you rent or own your home, one of these six options is likely to be a fit.

    APEC Top Tier 5-Stage Ultra Safe Reverse Osmosis Drinking Water Filter System (ESSENCE ROES-50)

    When it comes to wiping impurities out of your H2O, nothing gets it done better than the consumer favorite—and Amazon’s top seller—APEC Top Tier Filter. The American made filtration system gets rid of 99 percent of contaminants like arsenic, copper, lead, and more in your drinking water. It is a reverse osmosis system, which means it forces water through the membrane of the filter to remove impurities.

    Once the system is installed at your kitchen sink, there’s no need to stock up on replacement...MORE filters right away either as three of the five filters only need to be replaced every six months, and the other two filters should be swapped every two to three years. The unit comes with a lead-free chrome faucet for easy drinking. The faucet has two settings one which turns on the tap as long as you're pressing down on the button—ideal for filling your drinking glass, and the other that provides a continuous stream of water until you turn it off, which is perfect for filling up cooking pots or water bottles. Added to all of this are the Leak-Free Fittings, which ensure you won’t be wiping up spills every time you use it.

    Unlike portable filter options, this unit does require installation. But as long as you have the space under your sink for the filters and room on the sink itself for the additional tap, installation is relatively pain-free and takes about 30 minutes.

    APEX Countertop Drinking Water Filter - Alkaline (Clear)
    Courtesy of

    This filter not only removes contaminants, but is also adds some minerals back into the water. With the suggested RF-1050 replacement alkaline cartridges, which are said to adjust the pH level in the water using calcite, this removes chloramines, heavy metals, chlorine, and odors. It also controls microorganisms. The minerals it adds back are calcium, magnesium and potassium. The filters need to be changed after 1,500 gallons of water have been filtered. Since this has a standard-sized housing,...MORE you can also use other types of filters.

    This is a countertop unit, but it connects to the faucet at the nozzle via a flexible tube that fills the filter unit, which then dispenses the filtered water. It’s easier to install than an under-sink unit, and doesn’t need to be refilled like the pour-over countertop or pitcher units, but the tube isn’t particularly attractive and can get in the way of normal sink usage if left to dangle from the faucet.

    Sometimes you just want a simple and inexpensive way to purify water, and that’s where a pitcher like this one from Brita comes in. It’s nice because it cleans your water but you don’t have to install it on your sink. This one can hold 10 cups of water and can reduce the taste and odor of chlorine, copper, mercury, and cadmium, impacting not only the taste but even your health. You’ll need to change the filter out every 40 gallons or approximately every two months. There’s a handy sticker on the...MORE top for you to keep track of when it needs to be replaced. One filter is included with the purchase, but you can buy additional ones in packs of three for less than $15.

    Some people have had issues with it leaking while in the refrigerator, but one said that if you don’t fill it all the way to the top, that should help. A bonus for this product as opposed to the sink versions? Because it sits in your refrigerator, you’ll get extra cold water every time.

    PUR 3-Stage Advanced Faucet Water Filter, 7.7-Inch by 3.2-Inch, Chrome
    Courtesy of

    If you want filtered water right from your tap, but can’t install a reverse osmosis system, you’ll want one that attaches directly to your faucet like this PUR Advanced Faucet Filter. With one click, the unit attaches to your faucet and starts filtering as soon as you turn on the tap. And it filters out nearly 100 percent of all the lead, pesticides, mercury, and 70 other contaminants that might be in your water supply. Made from coconut shells, the PUR carbon filters are treated with hot steam,...MORE resulting in pores within every carbon grain. These grains absorb and lock-in pollutants.

    The filter swivels and adjusts 360 degrees to fit in most sinks, and is available in both a vertical and horizontal option depending on your space. Each filter lasts roughly three months, or 100 gallons, and an indicator light on the unit tells you when it needs to be replaced. While it is compatible with most standard faucets, it won’t attach to those that have hand-held sprayers built into the faucet itself. Reviews are overwhelmingly positive, aside from a few consumers who reported that their filters leaked after a few weeks of operation. But those were generally the exception.

    This high capacity water filtering tank has a bit of a cult following in certain circles, and for good reason. The Berkley Stainless Steel Water Filtration System is ideal for locations where a reliable water supply isn’t a given. No, you probably won’t need it in your urban apartment or house in the suburbs, but in a more remote home that relies on well water, it can be a life saver.

    The drum holds just over two gallons of water and can filter 3 ½ gallons per hour, removing cysts, parasites, and...MORE pathogenic bacteria. It can even handle untreated water from lakes or streams, if necessary. There are two different filtering options—the standard filters can last for 3,000 gallons or roughly 10 years, while the ones that also filter out fluoride should be replaced annually. Yes, this tank is on the expensive side, but for a reliably clean water supply it’s worth the cost.
