What to Consider When Buying a Reliable Countertop Water Filter


Tap water, despite some sources being considered safe to drink, could have dangerously high levels of dissolved organics because it flows through rusty pipes, dirty faucets, and other pathways that may contain decaying or toxic materials. This means that despite how clear the water looks when you drink it, it could easily contain toxic levels of copper and other heavy metals, as well as nitrates, phosphates, chloroform, arsenic and other dangerous waste products. That being said, water filters could easily remove a huge amount of contaminants from your water. In fact, most bottles of water you purchase actually contain filtered tap water. Fortunately, you don’t need to purchase a huge 16-stage filtering system or anything like that; there are countertop water filters that could easily fit under or beside the kitchen sink. You can find the best countertop water filter for your needs by using the following criteria:

Best Countertop Water Filter

Flow Rate

The rate at which tap water is filtered may not matter much if you just need a pitcher of water once in a while; however, if you need water for aquariums or baths, you will need to find a countertop filter with high speed filtration.


Contaminants Removed

While there is no single countertop filter that removes every impurity to date, there may be one that’s better than the other in terms of removing specific types of contaminants in the water. For example, activated carbon can remove heavy metals and certain types of organics, but it cannot remove traces of ammonia or nitrate in the water; it also leaks a bit of phosphate in the process, which means that a water filter that contains only activated carbon and some mechanical filter floss may not clean your water all that much. It’s important to check whether a countertop water filter has been tested by an independent organization regarding the types of contaminants it removes.



A countertop water filter should be easily attached to the kitchen sink. It must be compatible with a wide range of faucets and sinks, or at least the one you have at home.


Top Rated Countertop Water Filters in 2022


While it isn’t possible to choose a single best water filter for everybody’s needs, it’s possible to choose one for yours. That being said, we’ve included some of the best countertop water filter brands that people have tried, tested, and enjoyed. Check them out and see which ones may be a perfect fit for you.


New Wave Enviro 796515300000


1.New Wave Enviro 10 Stage Water Filter SystemThe manufacturer of the New Wave Enviro 10 claim that it can remove major contaminants to below EPA minimum levels, but leaves behind “desirable” minerals, such as potassium, chlorides (different from chlorine), magnesium, and fluoride. In a sense, you’re not producing distilled water from tap; rather, you’re producing mineral water from tap. It can produce about 1,500 gallons of water before needing to replace the filter. That would be approximately 75 5-minute showers or 24,000 cups of water. This would mean only having to replace the filter either once or twice a year unless when used for water-heavy activities.

What a lot of people like about this filter is that it is so easy to install. In addition, the filters don’t need to be changed too often (compared to other filters). It’s also relatively small and won’t eat up too much space. On the other hand, some users have reported that the metal valve that allows you to switch between filtered and unfiltered water quickly breaks. This isn’t too much of a problem as it only affects the automatic turn-off feature, as the valve, when broken, will not automatically turn-off the filter and will therefore require the user to manually turn it off. In the end, this countertop water filer is a great choice if you don’t mind having a few minerals in your water (especially fluorine) and possibly having to manually turn off the filter should the valve break.

Zen Water Systems 4G-MP


2.Zen Water Systems 4 Gallon Countertop Water FilterZen Water System not only filters tap water, but it also claims to be able to convert it to alkaline mineral water. The filter doesn’t require electricity, as it clumps together different layers of filter media inside a dispenser, letting tap water flow through it by the force of gravity. The first filter media tap water flows through is the micro-ceramic filter. This filter has tiny pores, about 0.2-0.5 microns in size, which make for a very good mechanical filtration system, since most microorganisms that cause disease are just about 0.5 microns in size. The next layer of filter media is the popular activated carbon that removes a lot of unwanted organics from the water, causing the water to become odorless and colorless. The next layer of filter media is the silica sand that holds back precipitates that contain impurities. The rest of the filter media mineralizes water, adding into it calcium, zinc, potassium, and manganese. It also turns the water alkaline in the process.

The Zen Water System also makes rather vague claims about being able to improve memory function, increase enzyme activity in the digestive track, etc. However, those claims have not been tested medically and therefore can’t be taken to be absolutely true. This filtration system can only filter 1.5 gallons of water at a time, and it does so slowly, as gravity takes its time. This type of filter is great for those who need clean tap water without fiddling with connections in the sink or plugging into an outlet.

Watts 500315


3.Watts 500315 Counter-Top Drinking Water FilterThe Watts 500315 Counter-Top Drinking Water Filter is one of the cheaper filters available, as its main mode of filtration is carbon filtration. Like most other countertop water filters, the Watts 500315 removes sediments and fragments from the water just fine. Because of its carbon filter media, it can remove chlorine, lead, and other organics and heavy metals.

While not having other layers of filtration available may make this product seem less valuable than other countertop drinking water filters, having fewer filter media actually allows water to be filtered faster, making it possible to filter higher volumes of tap water every day. Also, this makes replacing the filter media relatively cheaper, as you won’t have to buy several layers of filter media. You shouldn’t purchase this filter if you’re expecting to filter microorganisms like viruses and bacteria, or chemicals like arsenic and nitrates, as it won’t remove any of those significantly. If, however, you’re looking for a simple countertop water filter that removes the smell of chlorine, traces of lead and other heavy metals, as well as any possible color in the water, this filter may be a perfect fit for your kitchen sink.
