To find the best countertop water filter, you need to consider several factors. It’s important to understand both what these filters do and what they don’t do.
Despite their similar appearance, countertop water filters work differently from each other. They’re designed to remove chemical and biological contaminants that treatment facilities fail to eliminate.
The top-performing countertop water filters, based on performance data and customer feedback, remove various harmful elements, including chlorine, its by-products (THMs), volatile organic compounds (VOCs), lead (a toxic metal), pesticides, herbicides, micro-particles, and cysts.
After testing unfiltered water with different brands, including Big Berkey, Aquasana AQ-4000W, and Aquatru, the Big Berkey water filter was found to be the best.
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 is a countertop water purifier that removes nearly all harmful chemicals from your tap water. This purifier uses a unique four-stage ultra-reverse osmosis process similar to what is used by popular bottled water brands to eliminate 15 times more contaminants than pitcher filters.
The result is pure, clean water that is safe for drinking and cooking in the comfort of your own home.
The first stage of the process is mechanical filtration, which uses a process called Fickian diffusion. This process absorbs contaminants as the water passes over and moistens fibers.
The other three stages work together to remove unwanted chemicals while keeping beneficial minerals like calcium, potassium, and magnesium intact.
Aquatru’s ultra-reverse osmosis process is capable of removing particles as small as 5 microns. The system is compatible with any 10-inch cartridge, and a larger cartridge provides a wider surface area for more effective filtration.
The filter itself is sleek and stylish, with a chrome finish that looks great on your countertop. The Clear housing unit allows you to easily monitor the filter’s status and know when it’s time for a replacement.
And, perhaps best of all, the value proposition of Aquatru is that you can use the system for 6 months to 2 years and then dispose of the entire thing, making it a convenient and hassle-free choice for clean, pure water at home.
- Dimensions: 18 x 18 x 15 inches.

3. Aquasana Water Filter
Aquasana is a water filter that sits on your countertop, providing a convenient and low-maintenance way to purify your water. It’s a cost-effective alternative to other countertop systems and can produce up to 30 to 90 gallons of clean water per day, making it suitable for larger families.
The unique thing about Aquasana is that it focuses on removing as many chemicals as possible, resulting in really clean water.
It uses a four-stage filtration process to remove contaminants, such as chlorine, arsenic, fluoride, heavy metals, pesticides, sediments, rust, and other microscopic particles. The system is NSF certified to remove over 97% of chlorine and 76 other contaminants.
The filtration process starts with a sediment pre-filter that removes larger particles, preventing the rest of the system from getting clogged. Next, a coconut shell granular activated carbon filter removes unpleasant tastes and odors, cloudiness and colors, and volatile compounds.
Then, the reverse osmosis (RO) membrane removes TDS from the water, with a high rejection rate of 98 to 99%. Finally, another activated carbon filter removes any residual taste that may be left.
Despite removing unwanted chemicals, this filter preserves healthy minerals, such as calcium, potassium, and magnesium, to give you fresh-tasting water. The system can hold up to 2.5 gallons of water, making it easily accessible.
However, it’s limited to 500 gallons of water, which is roughly six months. To maintain water quality, you only need to replace the disposable pre-filters once or twice a year.
- 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.
- Easy to assemble.
- Value for money.
- The filter is expensive.
Undoubtedly, the water flowing from your tap may appear to be clean, but many harmful contaminants cannot be detected by our senses or even some specialized tests.
To ensure the safety of your family, it’s a wise decision to install a countertop water filter in your home. This will provide an effective and affordable solution to keep your family safe from these hidden threats.
It’s important to note that just because the water tastes and smells good, it doesn’t necessarily mean that it’s safe to drink. Even if there are low levels of contaminants present, the long-term effects are difficult to predict. Therefore, it’s better to be cautious and rely on countertop water filters to keep the contaminants at bay.
Thankfully, installing a suitable countertop water filter is a relatively easy and inexpensive way to keep your family safe and give you peace of mind. You can rest assured that the water you and your family drink will be free from harmful contaminants.

Depending on the type of water you use, the pH of the water may change after filtering water with Berkey. Alkaline water is slightly sweeter than pure water.
Pollutants increase the acidity in the water, and if you use Berkey water filter, it will filter out those contaminants and raise the alkalinity of the water providing clean drinking water.
When Should I Change My Aquatru Water Filter?
Use of the pre-filter for six months, the reverse osmosis for two years or 1200 gallons, whichever comes first, and the carbon filter for one year or 890 gallons before disposing of the whole system is needed to realize the value proposition of this water filter.
The Aquatru displays light to keep track of the working condition of the filter. Yellow filters (6 months), green filters (12 months) blue filter (24 months)

How Long Does Aquatru Water Filters Last?
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.
