List of Unauthorized Sellers

To ensure that you only receive the highest quality Berkey® products, Berkey® Water Systems is committed to selling its products through a trusted network of carefully selected authorized dealers. Berkey® Water Systems strongly advises customers to purchase only from authorized Berkey® dealers, and to be aware of the possible risks that may result from purchasing products through untrustworthy or unverified re-sellers.

There are unauthorized sellers that advertise and sell Berkey® products. These products may be defective, damaged, “B” stock goods, counterfeit products, knock-offs, stolen goods, or products obtained through secondary “gray” market channels. While these products may look like Berkey® products, it is important to know that they are not Berkey® products, and may not protect your loved ones as would genuine Berkey® products. NMCL cannot guarantee the quality or effectiveness of such products and as such, they are not covered by Berkey® Water Systems’ warranty or return policy. Please note that unauthorized sellers may appear on a marketplace site, hosted by companies such as Amazon, Ebay and similar marketplaces. Before purchasing Berkey® products on a marketplace site, consult the list of unauthorized sellers shown above, and then always confirm that the reseller is an authorized Berkey® dealer.

To verify that a dealer is authorized, look for one of the Authorized Berkey® Dealer logos (below) on their website. Note: this method of verification does not apply to third-party marketplace websites (Amazon,, etc.) where multiple sellers can appear on the same product listing.

It is fully your responsibility as a customer to ensure that the retailer you purchase from is an authorized Berkey® dealer.
