Buying bottled water can be expensive and arduous, and when you run out, it’s time to haul those heavy jugs back to the store or to call your delivery service. A countertop filter provides water on demand, with no waiting, no lift, just clean water.

1. Big Berkey Countertop Water Filter (Best Countertop Gravity Water Filter)
After testing dozens of models over the last 10 years, I am thrilled to recommend the Big Berkey Countertop Filter as our #1 pick for a countertop water filter. This amazing gravity-fed water filter is great for cabins and camping trips and an excellent option for everyday use in your home, especially if you have a small family.
One of the best things about the Big Berkey Countertop Filter is its portability and lack of dependence on a power source. This means you can take it with you on car trips or to places where clean water is not readily available. The kit comes with two purification elements, but it can hold up to four at a time, making it a flexible and versatile choice for any situation.
This filter is also incredibly effective at removing impurities from water.

Plus, with a lifespan of up to 6,000 gallons, you won’t have to replace the purification elements often.

While I love my Berkey, I also tested the King Tank from WaterDrop and found it reliable (filters out almost all the same containments as Berkey) and is a less pricy alternative.
So if you want to save a few bucks on this type of countertop filter, check out the King Tank.

⭐ 2. AquaTru – Reverse Osmosis Countertop Water Filtration System Review (Best RO Countertop)
So I tested the AquaTru Portable Water Filter System for two weeks and can attest to its effectiveness. This countertop water filter utilizes reverse osmosis technology to remove up to 99% of harmful contaminants, including arsenic, barium, cadmium, chromium, fluoride, copper, lead, and radium.
While it may not be my top pick, I still rank it as my #2 rated system in my best countertop filter list this year. The filter has a capacity of up to 90 gallons per day, making it suitable for families, and can be moved around for use in apartments or homes.
The device handles three quarts of water at a time, takes up very little countertop space with a small footprint of 14x12x14 inches, and best of all, the water it produces tastes great.
The AquaTru is designed to removed lead, arsenic, carcinogens, chromium, and drug residue, in addition to the standard threats of calcium, chlorine, and bacteria.
Installation is simple, requiring the system to be hooked up to your faucet and for water to be run through it. It works great for apartments or homes and is portable, allowing it to be moved around. However, it can only be connected to a standard faucet, so those with a hose or sprayer must replace their faucet before using this product.
The system does produce wastewater, called brine water, but this can be repurposed for other household tasks. While the filtration process may slow down water flow, this is common for most filtration systems, particularly those utilizing reverse osmosis.
For those with water pressure ranging from 40 to 80 psi, this is an excellent option for improving the quality of their drinking water. Whether you are an individual or part of a family, the AquaTru Portable Water Filter System is an effective and convenient solution.
- Ideal For: Apartments
- Certifications: NSF 42, 52, 58
- Capacity: 1000 Gallons on average
- Filter Type: Reverse Osmosis
- Tank: .75 gallon
Why I Love It (Pros)
Reverse osmosis is a very effective type of filter. This is easy to set up and maintain and has a good volume output.
Keep In Mind (Cons)
A bit bigger than other models I have reviewed in the past.
The AquaTru is easy to use, with quick-release twist-and-seal filters. The futuristic design can purify a gallon of tap water in just 12 to 15 minutes.Andrew Miles
3. Brondell H2O+ Countertop Water Filtration System Review (Best in-line Countertop Model)
An innovative three-filter design provides quality filtration without the time constraints of smaller reverse osmosis systems.
The Bronell H20 is a continuous flow filtering system that attaches directly to a faucet, providing as much water as you need without the sometimes cumbersome filling and emptying the reservoir from a standalone countertop system.
The three-stage filtering system is a patented Nanotrap technology, a process usually found in much more expensive under-the-counter filtering systems.
The small 11.5×4.25×11 inch design takes up only a little of your countertop space but provides an enormous supply of water.
Simple installation in under 10 minutes and an equally easy replacement filter make this a solid piece of equipment for people worried about the pollutants arriving from their municipal water supply.
The three-step process begins with the composite plus filter. This two-step filter traps rust, fine particles, organic material, and sand. It acts as a pre-filtering agent to screen out all the large particles that can flow into your home.
The nanotech filter is the second stage. Composed of cellulose and alumina fiber, it traps particles down to two microns. This clears your water, reducing turbidity.
The final carbon block filter reduces odor, bad taste, and is the final defense against contaminants such as chlorine, organic compounds, and microscopic particulates.
The composite and carbon filters need replacement every six months, while the recommended replacement interval for the nanotech filter is a year.
The filtering process is effective against bacteria and other waterborne organisms but doesn’t affect hard water.
If you have hard water with heavy iron, calcium, or magnesium content, this three process, the physical filter, will not remove or reduce the hard water levels. That’s the job of a water softener in large quantities or for a reverse osmosis system.
- Ideal For: Home or Office
- Color: White
- Material: Plastic
- Flow Rate: 0.2 – 1.0 gallons/min
- Item Weight: 2.99 pounds
Keep In Mind
This three-filter device does not produce distilled water as a reverse osmosis system does, but it is effective at removing smells, harmful contaminants, and bacteria from a water supply.
The advantages are easy to see. This is a low-cost, high-volume filter that is easy to attach, and provides long shelf life with low-cost replacement filters.
4. RKIN Zero Installation Purifier Countertop Reverse Osmosis Water Filter Review
Seventy-five gallons daily, from a countertop reverse osmosis filtration, is all you need to know about the AlcaPure by RKIN. This high-capacity countertop filtration system approaches the production level of full home units but at a fraction of the cost.
Weighing just 23 pounds, with a footprint of 14.5×9.5×16.25 this compact unit is a workhorse.
It comes in two varieties, one the AlcaPure edition for countertop alkaline water filter, and the OnliPure edition for zero TDS water.
Both units function the same, they’re just specifically designed to handle the additional challenges water in the PH7 to PH8 alkaline range can present.
This system is small enough to work in any kitchen, it fits compactly in apartments, and it’s even small enough to take with you in your RV.
The supply tank of the unit is located in the front for easy access. Its height allows it to fit under most kitchen cabinets on top of the lower cabinets.
This unit removes chlorine, lead, magnesium, and calcium from water. It is also effective at removing fluoride, other heavy metals, bacteria, and dissolved pharmaceutical drugs which by be dissolved in your municipal water supply.
There is no assembly required, the unit is filled with water by a jug from the tap. In about 15 minutes, you’ll have a half-gallon of pristine water. The system works similarly to a coffee maker.
The four-stage process ensures the best-tasting, odor-free water you’ve ever experienced.
Stage one allows the water to pass through a five-micron sediment filter. This removes large particles such as rust, sand, and sediment.
In the second stage, a coconut-based activated carbon block filter removes chemicals, pesticides, and other dangerous dissolved solids floating in your water.
The third stage is the reverse osmosis membrane. The system can produce an impressive 75 gallons of purified water per day.
The final stage applies AlcaPure’s patented post-filtering system. In this final step, calcium, magnesium, and other metals common to highly alkaline water are filtered out via an ion exchange process.
The resulting water is pure, odorless, chemically free PH balanced.
5. WaterChef C7000 Premium Countertop Water Filter System 1,000 Gallon Review
The WaterChef C7000 is the least expensive of the countertop water filters we’ve reviewed here. Its easy-to-use design lets a homeowner connect the filter directly to the kitchen faucet.
Not a reverse osmosis filter, but rather a series of physical filters, this device can still remove many of the harmful chemicals found in municipal water supplies.The C7000 removes 99+% of lead in your incoming water.
Weighing just 3.6 pounds, with a dimension of 6.75×4.75×10 inches, this is the lightest and smallest of the countertop water filters we’ve reviewed.
It has a filtering capacity of .75 gallons per minute. It will slow your faucet flow, but the water coming out of it will be vastly superior to the incoming municipal water.
It comes with a pre-installed filter, a battery, and a diverter valve assembly. The built-in mechanism warns you when it is time to install a new filter.
This is not a reverse osmosis filter so some of the chemicals that the reverse osmosis process filters will get through this system. The most notable is fluoride.
Because of its small footprint, many RV users take this unit on the road. It is even popular with boat owners. The filtering system works well with questionable water while camping or boating, providing clean, safe water for you to use.
Keep In Mind
Another common application for the C7000 is to place one in the kitchen, the laundry room, and every bathroom with a sink. The low cost and high function make it a perfect addition to any home water supply.
All you need is a pressurized water supply, the provided hose, an adapter, and open space on your counter, the C7000 does all the rest. Great tasting, safe water is just a few minutes away after this unit arrives.
6. APEX Quality Countertop Drinking Water Filter Review
The APEX countertop filter has many features that any homeowner would love. The chance to match your new filter to the rest of your kitchen is not always possible with other models, which made this system stand out from the start. We were impressed with the system’s flow rate; many times, with water filtration systems of all types, you will see a large decrease in water flow rate.
While there was some decrease in the APEX system, it was not noticeable enough to mention I had complaints about it.
The most important aspect of a countertop filter is its ability to do what it was made to do, filter. The APEX system removed large amounts of fluoride, chlorine, and other traceable heavy metals like lead. The water smelled and tasted much better than before.
The APEX is a solid solution if you are battling common tap water issues like chlorine smells, limescale build-up, or heavy metal.

9. Cleanwater4less Countertop Water Filtration System Review
The unique water delivery system of this countertop unit stuck out to us. By attaching the water diverter to your existing faucet, the water flows up through 5 stages of filtering and out of the chrome faucet. The chrome faucet features a black rubberized endcap that will help stop the build-up of any bacteria that can form when water is tuck in the faucet.
One thing I liked about this countertop filter was how long the water line is from the faucet diverter to the actual unit. This makes it easy to place the countertop filter anywhere you would like and get into the perfect place on your counter.
When it comes to filtering properties, the system removes chlorine with the best of them, and you can expect great tasting water due to the activated media stage of filtration.
- Ideal For: Easy-to-Clean
- Capacity: 10 Gallons
- Material: Stainless Steel
- Flow Rate: 1 GPM
- Stage: 5-stage

10. Home Master Sinktop Water Filtration System Review
The Home Master system is unique to our list because it is the first connected countertop option. If you have just a few extra inches on your countertop and are looking for a simple and affordable water filter, this could be your choice.
Installing the system is extremely simple; the water line attachment makes it quick. Once you have installed the waterline, you only need to twist the included dedicated tap and have a reserved freshwater system on your countertop.
The filter does an admirable job of removing contaminants, and you will see a reduction of about 93% when removing fluoride. It uses three different filter types, and they all have something they specialize in removing. Minerals like calcium, magnesium, and potassium will remain in your water supply while the contaminants are removed.

- Feed Water: PSI 20 – 90 PSI
- Height: 12 inche
