Black Berkey Filters

Basic Specifications of the Black Berkey Filters

Flow Rate: Each filter will have an approximate flow rate of 1 gallon per hour under optimal conditions. Filtration rates may be faster depending on the size of unit used (i.e. larger units will have more water pressure available to force the water through the filters due to the added weight from more water). The rates listed on the website are faster because they were calculated when water is continuously and simultaneously removed from the lower chamber and added to the upper chamber. Size: T...

Lifespan of the Black Berkey Filters

Each Berkey filter element has a life of 3,000 gallons: That’s an incredible 6,000 gallons for a two-filter system (less than 2 cents per gallon of water). This is possible because of the Black Berkey filter elements’ unique ability to be cleaned up to 100 times using a 3M Scotch-Brite pad.

Black Berkey® Purification Element Filtration Specifications

BLACK BERKEY®PURIFICATION ELEMENTS FILTRATION SPECIFICATIONS Black Berkey® Purification Elements are more powerful than any other gravity filter element currently available. The Elements have a unique purification capability that is due to their unique structure. The micro- pores within the Black Berkey® Elements are so small that viruses and pathogenic bacteria are simply not able to pass through them. Many water filters on the market may claim to be a water purifier, but do not meet the per...

When and how do I clean the Black Berkey® Purification Elements?

Black Berkey® Purification Elements don’t necessarily need to be cleaned every time one cleans their Berkey® unit. However, this can vary depending on your area and water source. In certain areas, the water contains a higher number of contaminants. In this case, it is necessary to clean the elements more frequently. If your water is muddy or really dirty we advise pre-filtering your water by running it through some type of cloth, ie: shirt, bed sheet, bandanna, cheese cloth etc. before putting i...

How to correct a slow filtration rate.

If you recently purchased your Berkey® System and water is passing through the filters very slowly, or not at all, the problem is typically due to high water tension. High water tension prevents air from being purged from the micro pores of the new purification elements. Your Black Berkey™ elements need to be primed to purge this air out of the micro pores and allow water to flow through them. Included with your Black Berkey™ elements is a tan priming button and instructions for priming. Please ...

Storing the Black Berkey Filters

We recommended storing the Black Berkey Filters if they will not be in use for 4 or more days. Below you will find the proper method of storing the Black Berkey Filters depending on the amount of time the filters will not be used. It is best to empty both chambers before storing because anytime water sits it becomes stagnant, which means it can grow bacteria. You may consider washing your chambers with soapy water before leaving them to dry. Short Term: If the filters will not be used between...

Why is my PH level higher after using the Black Berkey® Purification Elements?

When water is filtered through our system, the Black Berkey® Purification Elements increase the PH level of the water. This is healthful because pathogenic bacteria and viruses thrive in acidic environments and have difficulty surviving in alkaline environments. An environment with more alkalinity does have a higher PH level. The PH level will depend on various factors including what the PH level of the pre-filtered water is.

Can I use the Berkey® system with softened water?

The Black Berkey™ purification elements are designed to remove heavy metals, but will not remove mineral salts, which are added by a water softener. The salt in softened water has the tendency to clog the pores of the Black Berkey™ element. You can use one of our purification systems on a regular basis by bypassing your water softener to get your drinking water. Most water softeners have a bypass valve or way to get water before it passes through your softener. Therefore, we highly recommend tha...

Can I use my Berkey® system to purify water from my dehumidifier?

Dehumidifiers that use refrigeration will have cold metal tubes to turn water vapor from a gas to a liquid. According to the EPA, stagnant condensate water can harbor biological contaminants, including mold, mildew and algae, especially if the collection bucket isn’t cleaned regularly. These contaminants have the potential for causing diseases such as hypersensitivity pneumonitis and humidifier fever. Evaporation trays in air conditioners, dehumidifiers and refrigerators should be cleaned freque...

What is the Micron rating of the Black Berkey® Purification Elements

With respect to the micron rating, the manufacture does not use or publish a micron rating for the Black Berkey® elements for the following reasons: There is much confusion with respect to nominal and absolute micron ratings. An absolute micron rating is one that states the maximum pore size expected within an element. The nominal micron rating is the average pore size within the element. This means that if 90% of the pores are .02 microns and ten percent are 2 microns, one could claim the nomi...

The water in the upper chamber of my Berkey system does not drain all the way. Is this normal?

Yes it is normal and not unusual for the last 0.5in. to 1in. of water to remain in the upper chamber. By design, the water must pass through very fine micro pores within the filtration elements in order to pass from the upper chamber to the lower. The lower the water level in the upper chamber, the lower the pressure available to force the water through the micro pores. You may have noticed that the system purifies much faster when full than when half full. That’s because there is more water pre...
