A Comprehensive Comparison between the Aquasana and the Berkey

Heavy Metal Reduction

The Aquasanaand the Berkey are water purification systems. These systems have one simple objective – to remove as many contaminants as possible. Both the Aquasana AQ-4000W and the Big Berkey BK4X2 are able to reduce contaminants such as lead, mercury, pesticides, chlorine and others. As you noted, some of these contaminants are heavy metals. Heavy metals are notorious for causing a wide variety of problems such as stomach aches and some are rumored to cause cancer. Both the Aquasana AQ-4000W and the Big Berkey BK4X2 are able to remove such heavy metals.

Countertop

Water purification systems can be installed in quite a large number of configurations. Some can be installed under the sink, some are installed over the counter, and some do not need to be installed at all. The Aquasana AQ-4000W and the Big Berkey BK4X2 are both similar as both water purification systems simply require you to put them over the counter and screw them to your faucet to get filtered water right from your tap.

Non-Transparent

Some water purification systems come with the facility for you to see through the casing. This allows you to identify any potential problems and address them with great speed. Both the Aquasana AQ-4000W and the Big Berkey BK4X2 do not have such a design. They are both made from non-transparent materials and this is not a problem as it is quite easy to open them and check if all is well as they are in an easy to reach location. The Aquasana AQ-4000W comes with a white plastic design which is minimalistic and will blend in with your kitchen’s décor with great ease. The Big Berkey comes with a silver finish and this makes it a very stylish accessory to your kitchen.

Ease of Installation

The Aquasana AQ-4000W and the Big Berkey BK4X2 are very easy to setup and install. Since they are used over the counter, you do not need to worry about having to kneel in awkward positions and get a torch to illuminate your environment. They just require you to place them over the counter and if you are using the Aquasana, you screw it on the faucet and if you are using the Big Berkey you simply pour water into the top of the device.

Maintenance

The Aquasana AQ-4000W and the Big Berkey BK4X2 are very easy to maintain. Both these water purification systems come with filters that are small and quite easy to change. The process of changing these filters is so easy that you could assign this duty to your kids and they will be able to carry it out without any problems at all.

Electricity

The Aquasana AQ-4000W and the Big Berkey BK4X2 do not use electricity. The water purification technologies that they use do not require any electricity at all. This results in two things. The first is that you will have very huge cost savings as these systems will not increase your electricity bill unlike other types of water filtration systems.

Noise

Since the Aquasana AQ-4000W and the Big Berkey BK4X2 do not use any electricity, this means that they do not have noisy electric motors and other parts that generate a lot of noise. This results in devices that work very quietly. This will be quite pleasant to homeowners who have young children. Just imagine having your young born crying in the middle of the night because the kitchen’s water purification system woke them up. That would be rather unpleasant. With the Aquasana and the Big Berkey, you do not need to worry about this.

Usage

The Aquasana and the Big Berkey are used for different purposes in different environments. The Big Berkey is able to be used in more environments than the Aquasana. It comes with powerful Berkey filtration elements, a metal outer case and a small tap at the bottom. This allows you to use it in your kitchen, in your office, and even outdoors when camping as the powerful Berkey filtration elements will allow it to purify water from virtually any water source. The Aquasana can only be used indoors.

Flow Rate

The Aquasana is designed to have a much higher flow rate than the Big Berkey. It comes with a flow rate of 0.4 Gallons per Minute. This allows it to process much more water in a given period of time than the Big Berkey. This means that if you have a large family or an office which needs a lot of fresh water to be available at any given time, then the Aquasana will be a very good bet. The Big Berkey comes with a flow rate of just 0.033 Gallons per Minute. This makes it ideal for a small family.

Filtration Method

The Aquasana and the Berkey use different filtration methods. The Aquasana uses carbon filtration. It uses a 3 stagefiltration process in which there is carbon filtration, ion exchange and sub-micron filtration. It has claryum filter technology which gets rid of lots of harmful chemicals while preserving the healthy minerals found in water such as calcium. The Berkey comes with a different purification method. It uses a proprietary purification element. The element uses gravity to move water molecules through the filtration element. To make sure that all the unwanted chemicals are removed, the water remains in contact with the element for a long period of time so that the element absorbs as many contaminants as possible. This is one of the main reasons why the Berkey has a slower flow rate than the Aquasana.

Our Pick

We found the Big Berkey BK4X2 to be highly attractive. This is because it comes with a beautiful silver finish, it is very easy to install, it is highly portable and can be used in a wide variety of environments, and it is very quiet.

Why Do You Need a Water Purification System?

Health

Water from rivers, wells as well as water from taps is polluted with contaminants. These contaminants are not good for the body and they can result in illnesses and some are rumored to even cause cancer. Water purification systems remove harmful contaminants such as pesticides, lead mercury, chlorine, herbicides and more. Both the Aquasana and the Berkey are able to remove such harmful contaminants.

Portability

Due to recent developments in technology, the size of water purification systems has been greatly reduced. In the past, you would need to have large, bulky systems, but nowadays, there are water purification systems that are so small that you can easily carry them around with you and this will allow you to purify your water when you go fishing or camping. The Berkey is a good example of this.

Better Taste of Water

Water purifiers play a pivotal role in eliminating elements that make drinking water to have an unpleasant taste and smell. Such elements include chlorine and bacteria. Through the use of such systems, the taste will be greatly improved. Both the Berkey and the Aquasana give out water that is significantly better tasting than it was before undergoing the purification stage.

Less Consumption of Soap

As you probably know, there is hard water and hard water. The softer water that comes as a result of water purification does not leave minerals. This means that you will end up losing much less soap than you would if there was no purification. This is quite handy when you are cleaning dishes – especially when you are camping. There are usually limited resources present in such environments and stretching each resource will be of paramount importance.

Safety

Just in case you did not know, there is an underground system of pipes that are connected to each other and in many part of the country, these pipes are now old and use designs from a few centuries ago. This means that if another pipe, such as a sewer line gives way, your water can get contaminated. If you have a water purification system you will be protected from contamination.

Factors to Consider When Choosing Between the Aquasana and the Berkey

Design

The Berkey’s design is much better than that of the Aquasana. It comes with a silver finish and from just looking at it, you can see that it was made to last. It looks very stylish and it will blend into any environment in which it is put into. It adds that modern feel and this is what makes us love it so much. The Aquasana, however, is more geared towards minimalists as it is comes in a plain white design.

Flow Rate

The Aquasana beats the Berkey hands down in this category. The Aquasana comes with a flow rate of 0.4 Gallons per Minute while the Berkey has a flow rate of 0.033 Gallons per minute. If you have a large office with a lot of thirsty people coming in and out then the Berkey is not for you. If you have a small family then you may consider opting for the Berkey.

Portability

The Berkey is a portable water purification system. You can use it to purify your water on the go. This makes it perfect for carrying it with you for camps, fishing trips and even when you just feel like having a road trip. You will be guaranteed that you will have clean water as it has powerful Berkey filters that are quite powerful.

Maintenance

The Berkey and the Aquasana are both easy to maintain. However, you probably know that no two devices are equally as easy to maintain. One will be easier and cheaper to maintain while the other may be a bit more complicated to maintain. It would be a good idea to actually look for reviews from someone who actually bought one of each to hear what they have to say about the maintenance procedure.

Space

The Berkey is much bigger and bulkier than the Aquasana. It weighs 9.02 pounds and measures 8.5 x 8.5 x 19.25 inches. Now compare that with the Aquasana which weighs 2.99 pounds and measures 12 x 7 x 4 inches. This makes the Aquasana ideal for situations in which you have very limited space on your counter. If you have unlimited space, then the Berkey could be a feasible option for you to go for.
