Berkey Filters - Travel Berkey Water Filter, 5.7 liters

Travel Berkey

The Travel Berkey is Berkey's most compact system but contains the same powerful filters as all other systems. This unit can filter 5.7 liters per hour. We recommend this filter for 1-3 people.

Travel Berkey is perfect for use in areas where counter space is limited, e.g., in small apartments or RVs. It fits easily in a suitcase when traveling. Its capacity to accommodate up to two filters means it can provide drinking water for small groups of people or small families of up to three people.

The lid and the upper and lower chambers are all made from high-quality and durable 304 stainless steel that is designed to last a lifetime.

This water filter system comes with everything you need to start purifying your drinking water within minutes after assembly, including instructions. It comes with 2 Black Berkey Purification Filters.

What is a Berkey Water Filter System?

A Berkey water filter is an efficient, standalone water purification system designed to provide drinking water for daily use or in emergency situations. It requires no electricity as it is gravity-fed. Water from almost any source can be poured into the unit's upper chamber, and when it reaches the lower chamber, it becomes the purest and healthiest water you can drink.

How do Berkey Filters Work?

The Black Berkey filters, sometimes also called Black Berkey Purification Elements, are the real powerhouse of the Berkey system. They function according to different principles: absorption 1, absorption 2, and microfiltration. These methods are combined and blended to create a unique filtration process.

1. Microfiltration

The first line of defense against contaminants is the material that the Black Berkey filters are made of. Each cylindrical filter consists of a composition of more than six different media types, all constructed in a very compact matrix containing millions of microscopic pores. The microscopic topography on the filter elements' surface contains millions of tiny holes that allow water to pass through.

2. Absorption 1

The technology that Berkey uses for this step in the filtration process is ion exchange. Heavy metal ions (chromium, lead, or copper molecules) are extracted from the water through an ion exchange process where they are attracted to and transformed by binding electrically to the media. These molecules are absorbed and permanently bound to the filter.

3. Adsorption 2

Adsorption 2 creates an ionic barrier similar to surface tension. The barrier extending between the micropores blocks water contaminants, e.g., submicron viruses, that are smaller than the pore size itself. Berkey filters utilize the viruses' electrostatic charge and pull them towards the tunnel walls in the filter's "tortuous path". Similar to static cling, it holds the small viruses against the filter surfaces and never lets go.

Due to Berkey's gravity flow, it takes several minutes for water molecules to pass through the filter elements, while molecules in other filtration systems pass through in fractions of a second. The longer contact time results in greater separation of harmful water contaminants.

Filling Capacity:

Travel Berkey can provide 5.7 liters per hour.

Usage:

When you receive your Berkey, first wash all parts with warm water and natural dish soap. The filters should not be washed with dish soap; they can be rinsed with cold water and scrubbed with a sponge. The filter cartridges need to be primed, meaning they should be saturated to remove all air from them.

Each time you fill the upper chamber of your Berkey water filter system, you should fill it up to the top of the filters. If you only partially fill the system, the filters can wear unevenly. Always ensure the lower chamber is empty before filling the upper chamber to avoid overflow.

Maintenance / Cleaning:

What usually causes the filters to drip slowly is turbidity and sediment clogging the micropores in the elements. Simply remove the elements from your system and clean them by scrubbing the outside of each element under running water with a green scrubber (e.g., Scotch Brite) or a stiff toothbrush. It's easy to do and takes less than a minute per element. If they don't filter faster after cleaning, it's time to replace them.

What does the filter remove?

Over 200 contaminants are removed, including:

• Viruses (99.999%)

• Pathogenic bacteria (99.9999%)

• Chloramine (below laboratory detectable limits)

• Trihalomethanes (99.8%)

• Pharmaceuticals (99.9%)

• Most heavy metals

• Pesticides (below laboratory detectable limits)

Regarding fluoride removal: Recent NMCL laboratory tests show that Black Berkey filters initially reduce fluoride up to 99.9%. However, the filter loses this capability quite rapidly. In other words, they don't reduce fluoride for as long as the filter lasts for the other 200 contaminants.

Which Berkey water system should I choose?

Berkey water filter systems come in several different models. The most important factor to consider is how many people will be using the Berkey filter and how many liters of water are needed.

Also consider how the filter will be used - will the purified water be used only for drinking water or also for hygiene and cooking. Do you need a lightweight plastic version or a stainless steel model.

All models produce water of the same high quality. The difference between the models is the amount of water they can produce per hour and the size of the storage container. The most popular model is the Big Berkey in stainless steel, and it is excellent for an average household. Larger Berkeys also accommodate more filter elements, allowing the system to produce water faster due to the higher flow rate and have two extra filters if needed.
