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.

The Berkey Light is a popular system because it is portable, lightweight, and see-through. The Berkey Light can hold 2.75 gallons which is an excellent capacity. Another favorite feature of Berkey Light is the included base. The base raises up the entire system allowing space between the countertop and the spigot, so filling up a glass or water bottle is easier. Bonus: the Berkey Light LED Base, lights up water droplets so it glows!

No, in 2008 the manufacturer, New Millennium Concepts developed and released a Berkey Light system that is BPA-free. 

Before that, the Berkey Light systems were made of food-grade polycarbonate approved by the US Food and Drug Administration. Some research suggests that polycarbonates leach BPA (Bisphenol-A) when exposed to industrial grade alkaline detergents, or when repeatedly exposed to temperatures over 192 degrees Fahrenheit (88 degrees Celsius). Neither scenario occurs when using a Berkey Light normally. New studies concerning the possible leaching of BPA are ongoing. New Millennium Concepts decided to use an alternative to the polycarbonate previously used to produce the Berkey Light system. Fortunately, 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: 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 uses is also categorized into #7, although it is not a polycarbonate and does not contain any BPA.

It is rare but possible. Excessive pressure from over-handling the spigot could cause a stress fracture. For this to happen it takes extreme strain or force on the Berkey Light so regular use should not cause it to crack. 

Yes, the manufacture made a change in the plugs for the Berkey Light. Any Berkey Light made in 2014 or later will have slightly larger holes in the upper chamber and therefore slightly large hole plugs. This change was made to make the hole plugs universal between stainless steel systems and Berkey Light systems. 

The manufacturing date of your Berkey can be found on the embossing on the bottom of the upper chamber. Look for a circle with a two-digit number in it. A 14 in the circle indicates 2014.

If you notice something green in the lower chamber of your Berkey Light it may be algae.

Berkey water is purified water which means it is free of preservative chemicals that would stop algae growth. The Berkey Light is also transparent, which allows water into the chamber, creating a greenhouse affect. Both can create ideal algae conditions. 

To prevent the growth of algae relocate the system somewhere it where it's not in direct sunlight. Wash the chambers monthly with soap and water. Some customers place a pure silver coin in the lower chamber which prevents the algae from growing. This is due to the natural anti-microbial properties of silver.
