The filters we are going to talk about today have a different approach to water treatment, and both of these approaches are highly efficient.
The three filters are going to compare today are:
How the fight between AquaRain vs. Berkey vs. AquaTru is going to end up and who is the winner?
Let’s find out together!
All products are classed as the countertop filters which means that they are quite mobile to shuffle around the house or convenient for traveling.
If you are not familiar with countertop filters, don’t worry as especially for you I have written a guide where I explain everything you need to know about countertop filters.
Click here to check out the guide.
What makes the difference between these two products and other common countertop filters is the treatment performance.
Let me explain…
Conventional countertop units usually have a couple of stages, and the overall performance is not as good as for the more advanced systems.
These are different.
Units are quite big, and they use different filtration media type.
So let’s talk about each product individually and at the end pick the winner.
Before we start, I understand that you might not have time to read the whole article, so I have created a quiz to help you out.
Let’s compare these three units in the table below.
I will highlight all the main features so you have them nicely in one place.

AquaRain Model 303
Here is the deal:
The following two products I am going to talk about are both working on the same principle called gravity fed.
Basically, the principle is simple. Water is pushed through the filter by the gravity force, which gives you certain benefits.
The most obvious thing you will get is the fact that such filters are completely energy-free.
Both filters are made of stainless steel, which is my favorite material. I always love to see stainless steel products.
They are durable and likely to last you ages.
Let’s have a look at what AquaRain can offer to you.
The filter comes with two tanks bottom and the top tank with filters, and the capacity of 3 gallons.
It is straightforward to assemble, essentially the only thing you need to do is to screw the whole thing together. The manual is provided.
Here is the best thing:
AquaRain uses three ceramic filters. These have been proven to be very efficient when it comes to the removal of bacteria and cysts.
See the datasheet here.
On top of that, the carbon filter inside adsorbs well-known contaminants such as chlorine, odor, pesticides, and improves the overall taste of water.
The difference is:
We are used to measuring filter lifespan in gallons of water.
What I find interesting is the way that manufacturer measures lifespan of their filters. Well, it more of a shell rather than a filter.
Basically, they measure how many times you can clean the shell of the filter before it needs to be replaced.
What it means is that every time you clean the shell, the wall thickness is reduced.
At some point, you get to the end of the cartridge line because the wall is going to be very thin and this will become a point when you have to replace it.
The manufacturer claims that the ceramic shell will last roughly about 200 cleanings if you are doing it carefully with the light pressure.
Essentially, this should be able to produce more than a thousand gallons with careful manipulation.
The carbon filter inside of the shell should be replaced annually.
However, as to my standards, I suggest you do so no longer than every 6 months.
It will also be a good idea to clean tanks and shells quite regularly if you are continually using the filter.
I would suggest every couple of weeks.
What is disappointing:
Regarding the performance, the filter is able to produce roughly a 1 gallon of water per hour, which is let’s be honest slow.
However, assuming that the filter uses the gravity as the main force, it is not that bad.
When it comes to a warranty AquaRain is offering a great piece of a deal as well. The filter comes with 3-years limited warranty from the original date of purchase.
I must admit I am quite impressed with this filter. If you like to go to the nature for weekends or just like to camp this filter will be easy to take and efficient friend of yours.
With the great lifespan and metal materials combined with a 3-year warranty this filter is definitely worth considering.
Big Berkey BK4X2
I have written the review of the Big Berkey that is slightly bigger than this one in the other article, so make sure to check it out.
However, since we have a comparison article, it would only be fair if I highlight some of the features it offers.
Here is the thing:
The company British Berkefeld offers different types of stainless steel filters.
For this review, however, I have selected a Big Berkey type as I feel like it is comparable size with other products here.
The capacity is 2.25 gallons.
So here it goes:
The whole unit is made of the stainless steel as well as the AquaRain.
Compared to AquaRain, Berkey uses a different type of filtration media.
So, let’s have a look:
Big Berkey comes with 2 filters. There is, however, the option to install 4 filters which will increase the treatment rate and overall lifespan.
Combined lifespan is 6,000 gallons of water which makes it 3,000 gallons per filter.
Although, some sources have shown the real lifespan of about 1,000 to 1,500 gallons per filter.
These filters are called Black Berkey, and basically, they are made of carbon composite combined with 5 other media types.
I am not going into much details about the media as the most essential part of it is, that it works.
The reason why I am saying this is that because there is actual research done where Berkey was tested.
Yes, you are right. The study confirmed the performance of this filter.
Here is the link so you can read it yourself.
The great thing is:
That additionally you can get the optional fluoride filter, in case you want to remove fluoride from water.
Berkey can purify up to 3.5 gallons of water per hour with the set of 2 filters and twice as much with the set of 4 filters.
Basically, this depends on the quality of water in your area. So don’t panic if its less than that.
Some users have reported that their filter has arrived with dents or with the rust inside tanks.
People also experienced the “rubber taste.”
This, however, might be that the filter wasn’t appropriately flushed before the use.
Here is the tip:
Many people have reported that Berkey has provided them with pure water and improved its taste.
When it comes to a warranty, I am taking a few points down, because there is no information in regards to the warranty.
You will have to contact the manufacturer if you want to claim it.
Big Berkey is the great filter that provides and excellent level of treatment as well as the lifespan.
It can be nested for easy transportation which makes it a perfect filter to take on the trip.
Although, it is not perfect and some users have reported dents when they receive a product, or they have experienced rust after a while.
Here is the deal:
AquaTru is the countertop filter, but the way it filters the water is through the 4 stages of reverse osmosis filter.
What does it mean for you?
Reverse osmosis is known as the most advanced method of water purification currently available.
So, you can expect the fantastic filtration performance of this unit.
The filter has the following 4 stages:
This combination will remove most of the contaminants, and the performance is assured by the NSF Certification.
What I like about it…
Is the fact that it is an RO system built into the countertop block.
There is no hassle with installation as the whole unit comes as the one block with two dispensers.
First one is for the unfiltered water and the second tank hold purified water.
Other two units are both using a gravity fed technology that was explained earlier in this article.
Compared to the other two units AquaTru also requires a connection to the electricity.
Another thing I like:
Is the overall design of the product I mean it’s nice and sleek and is going to complement your overall kitchen design.
Although I prefer the stainless steel material as used in Berkey and AquaRain, this filter uses plastic material Tritan.
So you don’t have to worry about the health impact of Bisphenol as there isn’t one.
In terms of capacity:
The first tank has the capacity of 1 gallon and the second dispenser is able to hold about three quarts of water.
This is enough for drinking and even cooking.
Make sure to clean both tanks regularly to prevent bacteria to spread inside.
The speed of filtration is quite impressive to be fair. AquaTru is able to purify a gallon of water in more less 15 minutes.
Again, this depends on the overall quality of the water in your region. It might be a bit more or a bit less if your water is relatively clean.
What you need to know is that, AquaTru is able to purify 0.75 gallons out of 1 gallon of water leaving 0.25 gallons of water in the first tank.
When it comes to a warranty, the manufacturer offers the 1-year limited warranty.
I have noticed that customers quite often complained that it was hard to claim it. This would be the biggest drawback for me.
Another thing that I would love to see:
I would really appreciate if there is this ability to connect the whole unit directly to the water supply.
It would be much more convenient that way, at least for me.
The way it works now is that you have to take the tank off and pour water from the tap.
I mean it works fine, but it would be a nice option to have.
If you are looking for the great purifier that will remove everything out of your water than AquaTru is the way to go.
It doesn’t require any installation so you can set it up in 5 minutes, and the RO offers excellent performance.
Although, note that you might experience some troubles with customer service.
If I’m honest:
It is tough to conclude which unit is the best as all of these are doing well when it comes to performance.
Although, for Berkey and AquaTru users have reported issues related to quality.
If I compare AquaRain vs. Berkey.
I would select Berkey and here is why:
AquaRain is a great filter as well, but the reason it’s not a winner for me is that there is a lack of information.
Room for improvement:
What both filters are missing, at least for me, is some sort of water level indication.
You know, there is no way to tell how much water is inside unless you open it and check.
So, something that would tell me that there is a low level of water would be amazing, and I am pretty sure that many people would appreciate it as well.
This is the hardest part to compare two filters that are not really comparable.
Bekrey vs AquaTru!
I mean, if I compare the treatment performance then the winner would undoubtedly be AquaTru.
It uses the reverse osmosis filter, and as we know, RO is the most efficient type of filtration right now.
For example, if we compare these two products on the travel suitability, then Berkey would definitely take the win.
It is challenging to compare those two so for this reason, I have created a list with the main benefits of each of them and also there is a table at the beginning of this post.
AquaTru is great if:
I hope I have given you some good information so you can make an informed decision and pick the right product for yourself.
I would also love to hear your experiences with any of the products mentioned here.
