Mitre 10 has reissued its recall notice for a dehumidifier after it is suspected to have caused a house fire from which a mother and her three children escaped unscathed.
Waikato senior fire risk management officer Kevin Holmes said it was the family's smoke alarms which saved their lives on May 22.
It is suspected the fire started at about midnight in the dehumidifier which was in the hallway of their Melville, Hamilton, home.
The mother and her three children, aged 4, 8 and 13, safely escaped, with the oldest child even remembering to close the hallway door which helped limit the damage to one end of the house.
Mr Holmes said if the house didn't have its five smoke alarms, it likely wouldn't have had such a successful outcome.
