Countertop water filters are great when you want to ensure your family is drinking healthy water. In today’s post, I’ll compare three popular brands in market Aquatru vs. Berkey vs. Aquasana countertop water filter.
AquaTru vs. Berkey vs. Aquasana countertop water filter Comparison
Filtration technology used
Most filters use combinations of different elements such as carbon, reverse osmosis and mechanical filtration. The most common elements used by filters carbon filtration, reverse osmosis, and zinc-copper filters. Whereas carbon is the most effective absorbent material known to man, it does not remove some stubon contaminants like chloramine.
In addition, reverse osmosis is a technique used in water filtration where water molecules pass through a semipermeable membrane and get rid of ions and large particles from water. Reverse osmosis is applied is applied in combination with other filtration techniques such as carbon and KDF.
It uses a is a 4 stage filtration process. Mainly, it uses ultra reverse osmosis technology in a process where water is forced to pass through semi-permeable membranes, and all the contaminants are left on the other side. This technology is the same one that is used by most water bottling companies, so You can be sure that the water it produces will be of the same quality as bottled water.
Berkey BK4X2-BB uses a proprietary purification element that is made up of six elements. This element is patented by the mother company that owns Berkey water. This unique element uses gravity to move water molecules through the filtration element. It ensuring that water stays in contact with for a long time so as to maximize absorption of chemical contaminants.
Aquasana uses some four media to remove impurities and harmful chemicals in water. These four elements are activated carbon, catalytic carbon, ion exchange, and sub-micron mechanical filtration.
Which contaminants they remove
Different types of filters remove different types of contaminants depending on which filtration method adapted. To determine which type of model you want, you should consider which is the most appropriate for you depending on the type of water you have. By searching NSF’s database to learn what types of contaminants such model removes. In addition, reading the label on a product can help you know which contaminants it removes.
Some of the common types of contaminants found in water are the following. Sediments which refers broadly to visible particles for example sand, dust, and rust. Sediments are removed mechanically from water using sediments filters. Another group of contaminants is chemical contaminants which are removed using activated carbon filtration and reverse osmosis.
AquaTru is unrivaled countertop water filter when it comes to removing contaminants. The ultra reverse osmosis has been shown to remove 74 types of contaminants.
Purification element uses microfiltration that is able to block many types of contaminants. It is able to remove heavy metals such as lead, copper, mercury, aluminum. In addition, it removes submicron viruses through a process of ion exchange and other chemicals calcium, potassium and magnesium.
Removes herbicides, pesticides, chlorine, chloramines, copper, mercury and lead.
How much water it processes
The capacity of a filter is determined by the flow rate, port size, and the filter size. The flow rate is measured in gallons per minute (GPM). Most countertops have a flow rate of between 2.0 GPM and 2.5 GPM. In addition, the amount of water that it can process at a time which is determined by the size of the container.
This model can hold 3.75 Gallons at a time- It takes 15 minutes to process a gallon of water.
It can hold 2.25 gallons of water at a time- it takes about 9 minutes to process a Gallon of water.
When it comes to capacity to process a lot of water, no other countertop filter can rival Aquasana. It has the ability to process 0.4 GPM. More importantly, it has the capacity to filter 450 gallons per cartridges.
How much space you need
You don’t need to buy a bulky model which you might not have space for. The dimensions of models are as follows.
AquaTru= 18 X 18 X 15 inches
Berkey= 8.5 X 8.5 X 19.2 inches
Aquasana= 12 X 7 X 4 inches
Some home water filters are not safe because they might expose you to dangerous chemicals such as heavy metals like mercury and lead which can result in health problems such as damage to the reproductive system and kidney problems.
When it comes to safety, AquaTru is made of Tritan plastic. It is BPA free. In addition, it has a top lid to prevent airborne germs from getting into contact with the water.
When it comes to safety, Berkey incorporates a self-sterilizer which helps to ensure no germs go through the filter.
It is certified by NSF to standard 42 to remove contaminants.
Power consumption and type of power it uses
Not all home water filter run on electricity some are gravity feed. Whereas electricity run systems are efficient and can purify a large amount of water in a short time, They can’t run when there is a blackout. Gravity feed systems don’t run on electricity but use the power of gravity to push water through the filters.
AquaTru- 120 Volts
Berkey- Does not use electricity as it is a gravity-driven system.
Aquasana- It’s a gravity-based filter
The alkalinity of the water
Alkalinity is the number that measures how acidic water is. It is measured using a pH scale which ranges from 0 to 14. The higher you go on PH scale the more alkaline the water is said to be.
Although it has not been conclusively proved by research, alkaline water is said to have some health benefits such as regulating internal PH levels of the body to reduce the acidity levels. Maintaining low acidity levels is good for the body because it’s claimed that cancer thrives in an acidic environment.
It does not alter the water pH levels. AquaTru just removes contaminants while maintaining the same pH levels.
It does not alter the PH level of water. It simply removes all the contaminants from water. If you need to either increase or lower the water pH, you will need to use other additives such as baking soda, fresh lemons, and Drops.
Aquasana It increases the level of pH making it more alkaline.
According to the Water Quality Association, currently, there are four types of filtration that remove fluoride. This includes reverse osmosis, Anion exchange, activated alumina adsorption, and distillation.
Therefore, between the three countertop filter, the only one able to eliminate fluoride is AquaTru countertop. It uses reverse osmosis (RO) where water passes through a semi-permeable membrane and which eliminates 99% of all contaminants.
Pro and Cons
Big Berkey BK4X2 Countertop Water Filter Review
Aquatru is a 4 stage water filter that uses reverse osmosis to remove 99% of all the contaminants in water. Berkey uses a proprietary purification element that is made of six different media. Aquasana uses four media for filtration which includes carbon, ion exchange, and sub-micron mechanical filtration. Taking everything into consideration to compare AquaTru vs. Berkey vs. Aquasana countertop water filter. Berky BK4 based its performance and price considerations. It is an effective product that is proven to produce high-quality water. Not surprisingly, it has many great customer reviews.
