Definitions of Warranty

Limited Warranty- 
Mammoth Air Purifiers carry industry-standard limited warranty against defects due to manufacturing and shipping damages. Warranty does not include any use of the product that does not fall into the designed use of the product as intended by the manufacturer.  It is at the sole discression of the manufacture to determine if the warranty is void.   

Causes for Warranty Void-
- Humid environment that leads to corrosion of parts
- Unauthorize tampering of the unit
- Use of non-Mammoth parts (including filter)
- Irrgular maintenance of unit
- Electrical spike and damage due to wrong voltage/current
- Any other damages done not caused my manufacturing defect or poor craftmanship 

Repair and Substitution- 
Your unit will be repaired.  Unless we deem unfit for repair or discontiued item, Mammoth will offer a similar item of at least the same functions or better unit for replacement.   Once again, this is at the sole discression of Mammoth.  We will of course notify you of the problem first. 

Repair that's Outside of the Warranty Period or Limited Warranty Protection-
Should Mammoth deem your unit is beyond the scope of the limited warranty or timeframe of the warranty, Mammoth will notify you by phone (and by email if phone is unavailable) that your unit require repair that's beyond our warranty.  An estimate will be provided for the total cost and charges associated.  You will have 30 days to decide if you would like to proceed with repair or have the unit shipped back at your expense.  After 30 days, we reserve the right to discard your product.  

RMA or Authorized Return Only-
In order to serve you properly, all returns and repairs must have a RMA number.  Each product that we receive must corrospond a case number so we can properly update you and ship the product back to you.  We implement this policy so you can know each step of the process and track your product back to us.  Otherwise, your product runs into the chance of the discard pile (we don't want to throw your purchase away!)  Please contact us first before sending anything back.  We will open a case and give you a RMA number.    If you did not include a RMA number, we will reject the shipment back to you at your cost.
