Berkey Light Water Filter FAQ

The Berkey Light Water Filter system has a holding capacity of 2.75 gallons of purified water.  This Berkey system is a lower-cost, lightweight alternative to the stainless steel Berkey Water Filter systems. The Berkey Light System is perfect for small to medium-sized families ranging from 2-6 people.

To prevent the growth of algae, we recommend keeping the Berkey Light out of direct sunlight. The only other maintenance we suggest is to wash the lower chamber once per month with soapy dishwater. Calcium scale may build up on spigot and chambers after prolonged use using a hard water source. To remove scale build-up, soak affected part(s) in vinegar or a 50-50% mix of vinegar and water for about 15 minutes. Finish by cleaning with soapy dishwater. After regular use, the flow rate of your system may decrease. To speed up the flow rate, scrub the exterior of each purification element with a stiff brush or Scotch-Brite® pad and re-prime elements.

What makes the Berkey Light such a popular system is that it is portable, lightweight, and see-through. The Berkey Light also has a great amount of storage capacity at 2.75 gallons. A favorite feature of Berkey Light is its base. The base allows some space between the countertop and the spigot. In addition, when used with the Berkey Light LED Base, the water droplets light up and glow, which results in soothing patterns of light onto the surrounding area.

In the past, the Berkey Light systems were made of food-grade polycarbonate approved by the US Food and Drug Administration. Some research suggests that polycarbonates have been known to leach BPA (Bisphenol-A) when either exposed to high-strength industrial grade alkaline detergents or when they are repeatedly exposed to temperatures over 192 degrees Fahrenheit (88 degrees Celsius), neither of which occurs when utilizing the Berkey Light system. New studies concerning the possible leaching of BPA are ongoing. There has also been a wealth of misinformation circulated over the airwaves and the Internet. The FDA stated in April 2008 that it was not recommending anyone discontinue using products that contain BPA while they continue their risk assessment process. Even with such statements from the FDA, New Millennium Concepts determined that it was in the best interest of our customers to utilize an alternative to the polycarbonate previously used to produce the Berkey Light system. Fortunately, in 2008, a new product was developed that is BPA FREE. New Millennium Concepts, Ltd. replaced the polycarbonate material with this new material to alleviate any concerns our customers might have. Not only is this co-polyester highly durable and dishwasher safe, but it is also scratch, stain, shatter, and odor-resistant. PLEASE NOTE: Over the past year, there has been an increasing concern over containers that contain recycle code #7. The recycle code found on the bottom of plastic containers is called Resin Identification Codes. Polycarbonate is simply one type of plastic that falls under code #7. Code #7 is a catchall code that means “Other” most products that do not fit into categories #1 through #6 are placed into category #7. It is also for products made from more than one type of plastic in categories #1 through #6. The new co-polyester that the Berkey Light system utilizes is also categorized into #7, although it is not a polycarbonate and does not contain any BPA.

This is not something that happens very often. However, it is possible that if there is excessive pressure put on the spigot, it may cause a stress fracture. There would need to be a great deal of strain or force placed on the Berkey Light for it to crack or break.

The manufacture has made a change in the plugs utilized in the Berkey Light systems. The exit holes in the upper container of the Berkey Light systems have slightly increased. Accordingly, we have also somewhat increased the diameter of the hole plugs. This change was made so that the hole plugs used for the stainless steel systems are universal and can be used with the Berkey Light systems. The new larger-size hole plug will fit into all Berkey Light systems with the production year of 2014 or later. All Berkey Light systems with the production year of 2013 or earlier will require smaller hole plugs. The manufacturing date on the system can be found on the embossing on the bottom of the upper chamber. Look for a circle with a two-digit number in it. If the number in the middle of the circle is 14 or larger, then larger hole plugs are needed. If the number in the circle is 13 or lower, then smaller plugs will be required. If you require replacements for the smaller hole plugs, please get in touch with customer service for availability at 1-800-350-4170.

When the water has been purified, it is stripped of chemicals that would typically prevent algae growth. This is one factor that can allow algae to occur potentially. The second is light. Placing a Berkey near a window and in the sunlight, combining the purified water and heat from the sun provides ideal conditions for algae to grow. The LED Light of the Berkey Light Stand can create the same effect if left on too long. The growth of algae can be avoided by relocating the system away from direct sunlight or by not using the LED lights as frequently. It is also essential to wash the plastic housing monthly with soap and water. Our customers have reported that by placing a pure silver coin in the lower chamber, the algae cannot grow. This is due to the natural anti-microbial properties of silver. An American Eagle coin (99.999% pure silver) will work well if you prefer this option. While we would not know the exact type of growing algae, most blue-green algae are healthful food sources. We suggest Googling spirulina for more information about blue-green algae being healthful.
