Drinking tap water and using it for cooking and for washing the food can seriously affect your health. Tap water’s level of quality varies across the globe and only by making a chemical analysis of your water can you know just what type of contaminants it contains. The best way of protecting yourself from these contaminants is by installing a water filtration system. If a whole house water filter sounds too expensive, you can at least consider a countertop unit. The Aquasana countertop water filter is one of the best models on the market and it only costs $79.99.


As the name suggests, countertop systems are usually placed on the counter near the sink. As such, they are in plain sight so their design is very important. Furthermore, they must also be relatively small and have a compact size in order not to take too much useful countertop space. Given these facts, we were happy to discover that the Aquasana satisfies all these design requirements. It is very small and compact, it has a modern design and comes in three finish choices: black, white and gray. All you have to do is pick the one that best suits your kitchen decor. Moreover, they don’t interfere with a home’s pipe structure nor do they require a hole in the counter, so they can comfortably be used by renters.


It uses the highly efficient and NSF certified Claryum filtration technology. It has been independently tested by the NSF and it has proved that it can, in fact, remove over 60 water contaminants. This makes it 10 times more efficient than the leading drip pitchers. It uses catalytic carbon in order to target chlorine and chloramine, and it uses activated carbon in order to trap herbicides, VOCs, pesticides, and other organic chemicals. It also uses Ion-exchange in order to remove heavy metals. Last but not least, the sub-micron mechanical filtration captures even the smallest of contaminants such as giardia or cryptosporidium.

What we most like about Aquasana systems is their filtration technology. Unlike other competitive water filters, the Aquasana products remove solely the dangerous contaminants, without trapping beneficial minerals such as calcium, magnesium, and potassium. Thus the water delivered by this system is not only healthy but it also tastes great (demineralized water usually has a rather flat taste). This filter has a 450-gallon capacity. For an average household, a single filtration cartridge will last for about six months. This means that you will only need to replace the cartridges twice per year. Considering the fact that drip pitchers can need as much as 25 replacements per year, it has a capacity of 11 times more than the leading pitchers. By using it, you will be able to enjoy healthy, great tasting water at only 11¢ per gallon. The whole unit is certified under the NSF/ANSI Standards 42 & 53. The filter replacements cost $59. However, if you sign up for Aquasana’s replacement program, you will get a 15% discount on all cartridge replacements as well as free shipping benefits. It comes with two adapters and is compatible with most faucets except for the 2-in-1 faucets which have detachable sprayers.

Ease of Use

It is easy to install, easy to use and easy to maintain. It doesn’t require any permanent fixtures nor does it need to you drill a hole in your counter. In fact, even without any plumbing skills whatsoever, you can still install it in a matter of minutes.

Other considerations

Not only does it excel in efficiency but it is also environmentally friendly. Its design uses very little disposable parts. In order to recycle it, all you have to do is decompose it and put the plastic parts in your plastic recycling bag. You can put the carbon parts in your garden.

When considering various water filtration system, it is always better to choose certified products. Aquasana’s NSF&ANI certification is the best proof of this system’s efficiency. Moreover, according to countless customer reviews, it is also very durable. However, if you don’t believe us, you should know that this filter comes with a one year warranty and a 90-day satisfaction guarantee. Given the fact that it only costs $79, we consider this to be a very good deal.

    I live alone and I have bought this water filter approximately one year ago. Up to this point, I haven’t replaced the filters, and it hasn’t had any issues when it came to performance. I’m pleased with it, and I recommend it to others as well!
