Limited Warranty Policy

Revised: March 2023

This Limited Warranty Policy applies to the Masimo products (each, a “Product”) listed below and is given by Masimo Americas, Inc. (“Masimo”) only to the original purchaser of the Product from Masimo or any Masimo authorized reseller. Except where prohibited by law, this Limited Warranty does not extend to any subsequent Product owner or other person to who the Product is transferred.

Limited Warranty

Subject to the limitations below and as long as used in accordance with the directions for use, Masimo warrants to the original purchaser of a Product for the time period below (“Warranty Period”) that any new component included with a Product will be free from defects in materials and workmanship (the “Limited Warranty”).

The Limited Warranty gives you specific legal rights and you may have other rights that vary from state to state.

Masimo limits the duration and remedies of all implied warranties, including without limitation, the warranties of merchantability and fitness for a particular purpose to the duration of the Warranty Period. Some states do not allow limitations on how long an implied warranty lasts, so this limitation may not apply to you.

  • Hub: 1 year from date of purchase
  • Boot: 1 year from date of purchase (ordinary wear and tear excepted)

Masimo may change the availability of the Limited Warranty at its discretion, but any changes will not be retroactive.

This Limited Warranty does not apply to (a) any non-Masimo product, even if included or sold with a Product; (b) any software or application used with the Product, even if packaged or sold with the Product or embedded in the Product or (c) any non-Masimo network or system on which the Product operates. You should refer to the Terms of Use for the specific Product for additional details.

If a component of a Product becomes defective during the warranty Period, Masimo will, at its sole option, either repair or replace the defective component or Product, free of charge to you. Masimo will also pay for shipping and handling fees to return the repaired or replacement Product to you. The Warranty Period is not extended if Masimo repairs or replaces the Product. The Limited Warranty will apply to the repaired or replaced component for the remainder of the original Warranty Period, or 30 days from the date of replacement, whichever is longer, or for any additional period of time that may be required by applicable law.

To request Product repair or replacement under the Limited Warranty, please follow the steps under “How to Return a Product or Obtain Warranty Service” below.

What Is Not Covered?

The Limited Warranty above does not apply to: (a) any component of the Product that is: (i) not new or in its original packaging when supplied to you; (ii) modified; (iii) used with non-Masimo supplied or approved devices (including unsupported mobile devices), components, accessories, or software; (iv) disassembled or repaired by anyone other than a person authorized by Masimo; (b) normal wear and tear; (c) damage resulting from accident, misuse, abuse, negligence; or (d) failure to use the Product in accordance with the instructions and warnings provided with the Product or any published documentation.

Limitation of Remedies & Liability

The remedies in the Limited Warranty are your only remedies and Masimo’s entire liability for any breach of the Limited Warranty. Masimo’s liability under any circumstances will not exceed the actual amount paid by you for the defective Product, and under no circumstances will Masimo be liable for any consequential, incidental, special, or punitive damages or losses, whether direct or indirect.

Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. In these states, the liability of Masimo, its licensors, and affiliates will be limited to the greatest extent permitted by law.

If you have questions or want to obtain warranty service, please contact Masimo Customer Support by phone at (800) 916-1270 and email at customercare@masimo.com.

Under the Limited Warranty service, Masimo will ship a repaired or replaced Product to you free of charge. You are responsible for all other shipping costs unless prohibited by law.

Other Important Notices

The rights provided to you under the Limited Warranty are provided in addition to your rights and remedies under consumer protection laws and do not affect your legal (statutory) rights under applicable law.

The Limited Warranty is offered subject to Masimo’s Terms of Service for the applicable Product, which may change from time to time. You can find the latest version of the Terms of Service for each Product in the Product App, in the Product manual or packaging, or by calling Masimo Customer Support at (800) 916-1270. If there is a conflict between the Terms of Service for a Product and the Limited Warranty, the Limited Warranty will prevail. No Masimo reseller, distributor, agent or employee is authorized to make any modification, extension, or addition to the Limited Warranty.

Any product returned to Masimo without a valid warranty claim or without an RMA number may be rejected, returned at sender’s cost (subject to prepayment), or kept for 30 days and then disposed of at Masimo’s option.
