In 2022, Yahoo reported on the “tragedy” of an exploding bathroom that caused panic in the Chinese online community. In the photo, the toilet and sink, along with nearby objects, were heavily damaged. From the observation, it can be seen that the explosion was of significant scale. Many people wondered why this situation occurred?
The owner of the photo said that he heard a loud noise upstairs. He ran up and saw the bathroom on fire. Luckily, the fire was quickly discovered and extinguished, with no harm to anyone.
After conducting an investigation, the cause of the explosion was determined. Specifically, the ventilation fan had caught fire. The burning fan fell onto the toilet and caused the explosion.
According to statistics from the Fire Department of Hoa Lien (China), most bathroom fires are not caused by cigarette butts but by ventilation fans. The representative of the Fire Department pointed out that nowadays, bathrooms do not have windows, so the number of people installing ventilation fans is increasing. However, after many years of use, the fans accumulate dust, which can cause electrical malfunctions and eventually lead to fires and explosions.

Therefore, authorities recommend that people regularly check if their ventilation fans are functioning properly. If a fan makes strange noises, it should be checked immediately.
How to clean ventilation fans/odor exhaust fans?
Ventilation fans are usually installed in high or hidden positions. Very few users pay attention to cleanliness.
According to experts, if ventilation fans are not cleaned for a long time, it will affect their effectiveness and pose a fire hazard due to overheating, which will also affect the air filtration process.
Therefore, users should maintain the habit of regularly checking, cleaning, and maintaining their ventilation fans and odor exhaust fans. The appropriate cleaning frequency depends on the weather conditions and living environment. The ideal time recommended by experts is around 6 months per cleaning.
Below are simple steps for cleaning ventilation fans that users can do at home. Firstly, turn off the power to the device. Depending on the installation position and the wiring setup, users can either turn off the circuit breaker or unplug the fan from the socket.
Next, users should remove the outer cover of the ventilation fan. Since it is usually located in high positions, users will need a stable ladder or chair to perform this task. Additionally, it’s good to have something to catch falling dust from the fan.

After removing the outer cover of the fan, users should take out the fan from its holder. This step should be done carefully and gently. Avoid dropping the fan from a high place or hitting it hard, as it can cause the fan blades to crack, break, make loud noises, or reduce efficiency.
Finally, users only need to take the fan to a place where they can remove dust and use a soft cloth to clean it. For dirtier fans, water mixed with soap can be used for cleaning. However, before reinstallation, the fan blades should be wiped or dried.
For the outer casing of odor exhaust fans, ventilation fans, and the outer cover, users can clean them further by using a soft, dry cloth. In addition to cleaning, users can also consider calling professional technicians for in-depth maintenance tasks.
