There's been some discussion at cpaptalk regarding xPAP warrantees.SthrnRebel posted the Respironics M Series warranty:

"LIMITED WARRANTY
"Respironics, Inc. warrants that the system shall be free from defects of workmanship and materials and will perform in accordance with the product specifications for a period of two (2) years from the date of sale by Respironics, Inc. to the dealer. If the product fails to perform in accordance with the product specifications, Respironics, Inc. will repair or replace - at it's option - the defective material or part. Respironics, Inc. will pay customary freight charges from Respironics Inc. to the dealer location only. This warranty does not cover damage caused by accident, misuse, abuse, alterations and other defects not related to materian or workmanship."

So I dug out my Resmed VPAP Auto (S8) Users Manual to read the Limited Warranty. Its on the last page of the Manual.

And I took the liberty to look up the warranty in the back of my Resmed VPAP Auto manual. It states:

LIMITED WARRANTY
Resmed warrants that your ResMed product shall be free from defects in material and workmanship for the period specified below from the date of purchase by the initial consumer. This warranty is not transferrable.

ResMed flow generators - Warranty Period 2 years

Warranty does not cover:

a] any damage caused as a result of improper use, abuse, modification or alteration of the product;

b] repairs carried out by any service organization that has not been expressly authorized by ResMed to perform such repairs;

c] any damage or contamination due to cigarette, pipe, cigar or other smoke;

d] any damage caused by water being spilled on or into a flow generator.

... Warranty is void on product sold, or resold, outside the region of original purchase. Warranty claims on defective product must be made by the initial consumer at the point of purchase."

And then I dug out the Manual for the PR SystemOne BPAP Auto w/Bi-Flex. Shades of the M Series integrated humidifier!!! the warranty now reads

"This warranty does not cover damage caused by accident, misuse, abuse, alteration, water ingress, and other defects not related to material or workmanship."

*The bold emphasis is mine. I thought it was an interesting addition to Respironics' warranty given their experience w/their M Series integrated humidifier and their current touting of their new PR S1 "Drybox humidifier technology".

Anyway, neither of the above is the full limited warranty from either company. But it would be worthwhile and possibly of interest for everyone to actually read their PAPs Limited Warranty. WHEN does the Limited Warranty go into effect for your PAP?
