Several factors must be considered when looking for the best countertop water filter. It is just as vital to know what countertop water filters do as it is to know what they do not do.

Even if they all look nice on your sink, they don’t all work the same way.

Countertop water filters should block chemical and biological impurities that the treatment facility does not eliminate.

The finest countertop water filters, according to performance statistics and customer ratings, filter out chlorine, chlorine by-products (THMs), volatile organic compounds (VOCs), lead (a hazardous metal), pesticides, herbicides, micron particles, and cysts.

After testing unfiltered water with Big Berkey, Aquasana AQ-4000W, and Aquatru countertop water filtration systems, the Big Berkey water filter was determined to be the best water filter.

Here are the outcomes.

Unfiltered tap water:

  • Arsenic: 2.0 parts per billion (ppb).
  • Uranium: 240: 3.0 ppb.
  • Aluminum: 94ppb.
  • Fluoride: 0.8 ppb.

Filtered water with Big Berkey water filter

  • Arsenic: less than 1ppb.
  • Uranium238: less than 1 ppb.
  • Aluminum: 19 ppb.
  • Fluoride: 0.4 ppb

This analysis shows that the Big Berkey Countertop water filter provides perfectly clean drinking water.

AquaTru, Berkey and Aquasana Countertop Product Reviews

1. AquaTru Water Filter

Aquatru eliminates virtually all toxic chemicals. The countertop purifies water in a completely different manner, removing chlorine, sediment, rust, and sand as well as herbicides and pesticides.

It mimics the complete four-stage ultra-reverse osmosis process used by bottled water brands that have proven to eliminate 15 times more contaminants than pitcher filters, so you are guaranteed to get quality water right at home.

With Aquatru ultra reverse osmosis, particles as small as 5 microns are removed, and water is left very clean and pure. The system is compatible with any 10-inch cartridge. A larger 10-inch cartridge allows a wider surface area for more effective filtration.

The first step is mechanical filtration. Mechanical filtration takes advantage of Fickian diffusion. That diffusion process causes the absorption of contaminants whenever contaminated water passes over and moistens fibers.

As water passes over solid absorbent, particles in the water adhere to the surface. The other three filtration stages combine to cleanse unwanted chemicals while preserving healthy minerals such as calcium, potassium, and magnesium.

The stylish chrome filter sits atop your counter and filters water from your kitchen faucet. You are able to observe the filter status clearly thanks to the Clear housing unit, which allows you to see when the filter needs to be changed.

The value proposition of this water filter is that you use the system for 6 months to 2 years and then dispose of the whole thing.

Product information

  • Dimensions: 18 x 18 x 15 inches.
  •  NSF/ANSI certified to remove 82 contaminants.
  •  You can use any 10-inch filter cartridge when it comes time to replace.

  • Fragile.

2. Big Berkey Water Filter

In comparison to other filtration systems, Berkey’s water filter system is the best water filter for home use. Its filtration system is more of a purification process than a filtration method.

This large cylindrical housing tank has two black Berkey water filters, two fluoride elements, and a spout for water flow. In addition to being a top quality water filter, it generally comes with an extended manufacturer’s warranty.

With this stylish chrome filter, you will have clean drinking water available at any time from your kitchen tap. Berkey’s fame comes from its ability to permanently eliminate pathogenic bacteria.

Its 1.0 Micron reliable block filter cartridge removes even super tiny particles of impurities, including things like rust, chlorine, and other materials, from the water.

After removing contaminants, the filter also includes a remineralization phase, which adds calcium back to the water to improve its pH and offers a more enjoyable taste.

This massive stainless steel water filter lasts significantly longer than other filters on this list with a capacity of filtering 1000 gallons and can hold up to 2.25 gallons.

This is a major appeal as it will ensure that you will have plenty of water on hand when you’re thirsty. The filter also comes in a variety of colors, allowing you to personalize it for your kitchen.

Besides the most optimal performance results, you should look closely at the number of gallons the cartridge has filtered before replacement is needed.

Product information

  • Dimensions: 8.5 x 8.5 x 19.25 inches.
  •  Material: stainless steel.
  •  Holds 2.25 gallons of purified water.

3. Aquasana Water Filter

Aquasana is a countertop-based water filter that offers a low-maintenance, cost-saving alternative to other typical countertop systems.

With a maximum output of 30 to 90 gallons per day, this water filter promises plenty of water even for larger families.

It employs four stages of filtering and removes chlorine and other contaminants. What differs from this water filter is that they focus mainly on filtering out as many chemicals as possible, creating really clean water.

It is NSF certified to remove over 97% of chlorine and 76 other contaminants such as arsenic chromium six copper, fluoride, heavy metals, pesticides, sediments, rust, and other microscopic particles.

In the first stage of the process, a sediment pre-filter is used to filter out larger particles, in order to prevent the rest of the system from getting clogged.

Next comes a coconut shell granular activated carbon filter that absorbs chlorine unpleasant tastes and odors, cloudiness and colors, and volatile compounds.

In the next step, the RO membrane is used to remove TDS from the water with a rejection rate of 98 to 99%. As a last step, another activated carbon filter is added to the process in order to remove any residual taste that may be left.

Although this twin cartridge 4 stage filtration system removes unwanted chemicals, it preserves healthy minerals such as calcium, potassium, and magnesium to give you fresh-tasting water.

A major perk with this filter is that it can hold up to 2.5 gallons of water, making the purified water much more easily accessible.

This water filter is limited to 500 gallons of water. This equates to approximately six months. All you have to remember is to replace the disposable pre-filters once or twice a year to guarantee water quality.

Product information

  • Dimensions: 12 x 7 x 4 inches.
  •  A flow rate of 0.4 GPM.
  • Only 11 cents per gallon.
  •  Certified to remove 97% of chlorine and reduces 76 other contaminants.
  • Easily attaches.

Your Aquatru water filter machine should tell you which filters to change. You are recommended to keep track of the filter when you install it.

Yellow filters (every six months), Green filters (every 12 months), and Blue filter (every 24 months).

Does Aquasana Water Filter Soften Water?

Aquasana EQ-300 can filter out synthetic chemicals like prescription drugs, chlorine, lead, VOCs, THMs, herbicide and many more contaminants, while also softening the water.

The primary purpose of filtration is to make the water as healthy as possible.

When considering the purchase of a whole house water filter and a water softener, you should keep a few things in mind.

1. One of the first things to look for is that a whole house water filter system utilizes a multi-stage filtration process that is certified by NSF.

Typically, if your home is on city water, the whole home system goes before the water softener. This is to remove chlorine before it mixes with the resins inside of the softener.

2. If you use well water, then chlorine is not a problem you have to deal with. In this case, it is a good idea to have the whole house filtration system treats the home after the water softener.

3. The main purpose of a water softener is to remove high levels of “hard” minerals such as calcium.

However, many whole house filters are capable of reducing iron, calcium and other hardening agents down to five microns, yet still, retain healthy minerals.

In other words, your home water filter system won’t be as effective at removing hard water but will still perform similarly to a standard softener.

The big difference being that no sodium is added, which is a lot healthier for you and your family.

Since the water softening process adds sodium, you are not distributing the purest water possible throughout your home.

The water becomes so full of salt that it can be tasted. If your home currently does use a softener, the water you drink must be filtered at the point of use.

4. In addition to removing minerals, some softeners can also reduce other contaminants like heavy metals and sulfates.

They nonetheless don’t even come close to the ultra-filtration capability of a high-quality whole house filtration system.

In conclusion a home filtration system such Aquasana water filter gives a lot of benefits, such as healthy drinking water, filtered showers and baths, longer-lasting appliances and less chloroform gas in the air.
