What happened
A $760 Dyson humidifier–air purifier was purchased with a 2-year manufacturer warranty.
From early on, the unit experienced repeated malfunctions.
During initial support interactions, Dyson advised that the product should be used only with distilled water, suggesting that water quality could affect performance.
The owner followed this guidance and used distilled water exclusively, purchasing it separately and continuing use as instructed.
Despite this, the unit continued to fail. Eventually, the main control board failed, rendering the product unusable.
Replacement details
Dyson replaced the unit after the main board failure.
However:
- The replacement unit came with only a 1-year warranty, rather than the original 2-year coverage.
- The replacement was later confirmed to be refurbished, not new.
No option to retain the original warranty term was offered at the time of replacement.
What happened next
After continued use — still following Dyson’s guidance to use distilled water only — the refurbished replacement unit failed again, exhibiting further reliability issues.
At this point, Dyson declined additional repair or replacement, stating that more than two years had passed since the original purchase date, placing the product outside the original warranty window.
Current status
- The product is completely non-functional
- No further repair or replacement was offered
- The customer incurred ongoing costs for distilled water, as instructed, despite the failures continuing
Key facts (summary)
- Original warranty: 2 years
