January 12, 2026 – A consumer has reported a fire incident involving a Dyson Purifier Hot+Cool Formaldehyde HP09 (White/Gold) unit. The incident, which occurred on November 27, 2025, involved a flame erupting from the power cord’s plug area while the device was in normal operation, raising concerns about potential product defects and fire hazards.
Product Details
Incident Overview
On November 27, 2025, a consumer reported a serious incident where a Dyson Purifier Hot+Cool Formaldehyde HP09 unit caught fire. The unit, one of two HP09s purchased in December 2024 and still under warranty, was plugged directly into a standard wall outlet in a living/working area and had been operating on a normal setting for approximately 25 minutes.
The consumer, seated about eight feet away, heard an unusual noise and then observed an actual flame originating from the plug area of the Dyson’s power cord, specifically where the plug connects to the wall outlet. There were no prior indications such as sparking, smoke, or visible damage to the outlet itself before the fire. The flame clearly emanated from the plug, not from inside the wall.
The individual immediately unplugged the unit, at which point the flame extinguished. While no physical injuries occurred, the power cord and plug of the Dyson unit sustained damage, rendering it unsafe for further use. The consumer highlighted the severity of the fire hazard, noting that the outcome could have been significantly worse had they not been present to intervene.
The consumer also emphasized that the outlet in question has never caused overheating, fire, or electrical disruption with any other appliance before or after this incident. Additionally, the second Dyson HP09 unit owned by the consumer (same model) had previously failed internally, displaying repeated error messages and ceasing to function despite troubleshooting. This suggests a broader pattern of reliability concerns with the HP09 model. The consumer expressed heightened concern due to similar complaints from other consumers and Dyson’s past recalls for fire-related hazards, specifically mentioning the AM04 and AM05 Hot+Cool heaters.
Safety Concerns
This incident presents significant safety concerns, primarily revolving around the risk of fire and electrical hazards:
- Immediate Dangers: The direct ignition of flame from the power cord plug poses an immediate and severe fire risk. Such an event can quickly escalate, leading to house fires, property damage, and potential injury or fatality from burns, smoke inhalation, or electrical shock. The lack of prior warning (no sparking or smoke) makes this particularly dangerous, as consumers may not have time to react.
- Long-Term Risks: Unaddressed electrical issues can lead to persistent fire hazards, potentially causing extensive property damage or even total loss of a home. There’s also the psychological impact on individuals who experience such a close call.
- Who Might Be Affected: Anyone using the Dyson Purifier Hot+Cool Formaldehyde HP09, particularly those who leave the device unattended or use it in areas where they might not immediately notice a problem, could be at risk. This includes families, individuals in residential settings, and even businesses.
- Property Damage Potential: A fire originating from an electrical appliance’s plug can rapidly spread to nearby furnishings, walls, and other combustibles, leading to significant and costly property damage.
- Historical Context: The consumer’s reference to Dyson’s past recalls for fire-related hazards (specifically models AM04 and AM05) due to electrical short-circuiting adds a layer of concern, suggesting a potential pattern of thermal and electrical risks in certain Dyson products.
What Consumers Should Do
Consumers who own a Dyson Purifier Hot+Cool Formaldehyde HP09 or similar Dyson heating/purifying products should take the following precautions:
- Immediate Steps: If you observe any unusual noises, smells, smoke, sparks, or flames originating from your Dyson HP09 or its power cord/plug, immediately and safely unplug the unit from the wall outlet if it is safe to do so. If a fire has started and cannot be immediately extinguished, evacuate the area and call emergency services.
- Check Your Product: Verify if you own a Dyson Purifier Hot+Cool Formaldehyde HP09 (White/Gold) or other HP09 models. Locate the model number on your unit.
- Prevention Measures:
* Inspect Cords and Plugs: Regularly inspect the power cord and plug for any signs of damage, fraying, discoloration, or melting. Do not use a damaged unit.
* Outlet Condition: Ensure that your wall outlets are in good condition and not loose or worn. While the consumer in this incident reported no prior issues with their outlet, the manufacturer suggested a loose or worn outlet could be a factor. Loose outlets can cause arcing and overheating.
* Direct Connection: Always plug high-powered devices like the Dyson HP09 directly into a wall outlet. Avoid using extension cords, power strips, or surge protectors, as these can sometimes be overloaded or contribute to overheating if not rated for the device’s wattage.
* Monitor During Use: Be attentive to any unusual noises, smells, or heat emanating from the unit or its plug/cord during operation.
* Unplug When Not In Use: Consider unplugging the unit when it is not in active use, especially for extended periods.
- Reporting Procedures:
* Report any similar incidents or concerns to Dyson, Inc. directly.
* File a detailed incident report with the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report contributes to a database that helps identify potential safety trends and may lead to investigations or recalls.
