10 Best Countertop Water Filters 2025 in the United States

The Bluevua RO100ROPOT-UV Reverse Osmosis System is an impressive countertop water filter designed for those seeking clean and safe drinking water. Its standout feature is the advanced 6-stage filtration system, which includes a UV light and a remineralization filter. This means it not only reduces harmful contaminants like lead and chlorine but also adds essential minerals back into the water, enhancing both taste and health benefits. The filter is certified for lead-free performance.

A major strength of this filter is its ease of use. There’s no need for complicated plumbing; just plug it in, and it’s ready to go. The glass carafe is a nice touch as it reduces the risk of plastic pollution, making it a more sustainable choice. Additionally, its power-saving features and impressive water-saving ratio of 2:1 help conserve both energy and water, which is appealing for environmentally-conscious users.

However, it does have some drawbacks. The maximum flow rate of 0.26 liters per minute may be slower than some users expect, especially if you need to fill large containers quickly. This could be a consideration for families or those who entertain frequently. Also, while the filter life of 1-2 years is advantageous, users must remember to monitor the filter status as forgetting to replace it can affect water quality.

Despite its weight of 23.15 pounds, which may make it less portable for some, the system’s design is attractive and functional for countertop use. The Bluevua RO100ROPOT-UV is a solid choice for individuals or families looking for effective, portable water filtration without the hassle of complex installation.

The APEC ROES-50 Essence Series is a reverse osmosis water filter designed to deliver very clean and safe drinking water by removing up to 99% of common impurities like arsenic, lead, chlorine, fluoride, and over 1000 others. It uses a 5-stage filtration process that’s WQA certified, which means it meets high-quality standards for water treatment. This system is great if you want water that tastes much better than typical tap or bottled water and are concerned about heavy metals or other contaminants.

Its flow rate is quite slow, at about 0.03 gallons per minute, so it won’t produce water instantly. Also, this model is meant to be installed under the sink, so it’s not a simple countertop plug-and-play filter and may require some installation effort. The unit is a bit bulky, measuring 16 by 5.25 by 17.5 inches and weighing around 25 pounds, so make sure you have enough space. It includes a lead-free faucet and durable tubing, which adds to the safety and durability of the system.

If you have moderate to high total dissolved solids (TDS) in your water source, this system can handle up to 2000 ppm, which is quite robust. This filter represents a solid choice for those wanting thorough purification and who are okay with slower water output and a bit of installation work. It’s especially suitable for people with concerns about specific contaminants and who prefer a reliable, long-lasting system.

The Big Berkey Gravity-Fed Water Filter System is a solid choice for those looking to improve tap water quality without complicated installation. Its standout feature is the Black Berkey Elements, which use a special blend of filtering media capable of removing over 250 contaminants, including common chemicals and pathogens. This means the water you drink is not only clearer but safer. The system doesn’t require electricity or plumbing, making it easy to set up on any countertop. With a 2.25-gallon capacity, it’s well-suited for daily household use or small offices. The deluxe 7" stainless steel spigot with a water level indicator adds convenience, so you can see when it’s time to refill without lifting the top chamber.

Each filter element can last up to 6,000 gallons, which is economical and reduces frequent replacements, but if your water source is heavily contaminated, you might need to replace filters sooner. The unit is compact and attractive enough to fit in most kitchens, though it weighs a bit over 8 pounds, so it’s not ultra-lightweight but still portable.

The Big Berkey offers reliable, high-quality filtration with an easy setup and long-lasting filters, ideal for individuals or families who want a straightforward countertop solution without plumbing hassles, though it might not be the fastest filter option available.
