What is a Counterfeit Product?




Counterfeit hot tub products are unauthorized replicas of branded items—often sold online at discounted prices. They range from filters, jets, pumps, heaters, electrical components, sanitizers, to control panels. The most common that is appearing in the past year are the FreshWater Salt System Replacement Cartridges. These products may carry the appearance of genuine parts but lack the testing, certification, and materials that ensure compatibility and safety.

The Dangers of using Counterfeit Products

Starting with the obvious, counterfeit products are not the real thing. These products lack proper safety certifications, are made with inferior materials, and can cause a variety of issues. Using "fake" products in any circumstance will not yield the results you are seeking; in fact, this will often cause further problems down the road. Let's just list some of the issues that can occur: 


  • Equipment Failure
  • Water Contamination
  • Electrical Hazards
  • Costly Repairs
  • Voided Warranties
  • Negative Reviews
  • Health and Safety Risks

One of the biggest counterfeit products that has been circulating in the past year have been the FreshWater Salt System Cartridges. Watkins emphasized the seriousness of this issue by giving the following:

"...there has been an uptick in unauthorized resellers (primarily China-based) selling counterfeit FreshWater Salt Cartridges online. These counterfeit products fail to meet performance standards and can pose serious safety risks to users and jeopardize the operation of their hot tub. Additionally, they have led to a multitude of negative online reviews from unsuspecting consumers who have purchased counterfeit FreshWater Salt Cartridges."

🔍How to Identify

Too Good to be True Pricing

  • Deeply discounted prices compared to the manufacturer’s website are a red flag
  • Counterfeits often lure buyers with deals that seem unusually low

Lack of Certification Labels

  • Genuine electrical components and filters carry certifications like UL , CSA , or CE

  • If these marks are missing, incorrect, or poorly printed— it’s likely a fake


Generic or Poor-Quality Packaging

  • Real parts come in branded, tamper-evident packaging with product codes

  • Counterfeits may arrive in plain boxes or bubble wrap, with no branding or instructions


No Serial Number or Model ID

  • Authentic products have traceable serial numbers or model IDs

  • If a part has no identifiable markings, it may be counterfeit


Unknown Seller or Unauthorized Marketplace

  • Avoid buying from third-party sellers without a proven track record

  • Some online marketplaces host unauthorized resellers—check the seller’s reviews and ratings



How to Avoid

Buy From Authorized Dealers or Directly from the Manufacturer

  • Use the manufacturer’s website or a trusted spa supply store

  • Most brands list official dealers on their websites


Verify Product Codes Before Purchase

  • Look up product numbers on the brand’s site to confirm they’re legitimate


Avoid "Universal Fit" or "Compatible With" Claims:

  • These are often used by counterfeiters to bypass model-specific standards


Ask for Proof of Authenticiy

  • Reputable sellers can provide manufacturer documentation or receipts


Keep All Receipts and Packaging

  • This helps validate your warranty and makes returns easier if you suspect a fake


Consult Your Hot Tub Manual or Technician

  • Use only the parts and chemicals recommended by your spa’s manufacturer



What Steps You Should Take

to have peace of mind in your hot tub




  • Always buy from an authorized dealer
  • Register your spa and components for warranty coverage
  • Keep a maintenance log of service repairs and chemical maintenance
  • If unsure about anything - refer to a spa professional before installing any new part
