What the CPSC Data Shows
Humidifiers (CPSC product code 304, in the Kitchen Small Appliances & Housewares category) generate an estimated 628 emergency-room visits every year in the United States, adding up to roughly 12,568 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 36/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are rising by about 49% over the last five years, with the busiest year on record being 2023 (1,278 estimated ER visits) and the quietest 2008 (209 estimated visits).
The single most common ER diagnosis for humidifiers is laceration to the head, accounting for approximately 843 visits across the 20-year NEISS window, followed by poisoning to the all parts body (792 cases). The 0-4 age group absorbs the largest share of injuries, about 5,133 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 6.7% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 99 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how humidifiers fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Consumer Incident Reports
Reports filed by consumers on SaferProducts.gov.
We woke up in the middle of the night to a strong burning smell which we traced to the humidifier. We immediately put it in the trash suspecting that there may be a risk of fire. Recently we received the "fix" for this problem from QVC, but the product had already been disposed of.
The Safety1st brand Ultrasonic 360 Humidifier was purchased, in blue, for my son last year. It was used off and on for about 14 months. Proper cleaning and care was taken. It soothed my son to sleep many times as he needed the humidity. On the morning of September 25, 2012 I noticed a sickening sweet smell coming from my sons room. I figured it was the humidifier because sometimes it would make the air chalky, but this was different. I also noted that the green light was on but the chamber of water was empty. I turned it off and immediately aired out the room and checked on my son. The product malfunctioned. Somehow the "auto shut-off" mechanism was not triggered. The bottom of the chamber was tinted brown. The black portion of the center well fell and melted through the bottom of the whole thing. My home has this invading smell from the plastic. The fumes emitted from the melting are not pleasant.
I have been using 2 of the Boneco Ultrasonic U200 humidifiers in my childrens room. About 6 months after purchase I noticed a loud screeching coming from the transformer that plugs into the wall. I received a reply from the company stating it was normal. As the dry season is coming I started using them again. After the second night my daughter woke up to a burning smell. Upon examination it was identified to be the U200 Boneco humidifier. It was smoking and the bottom was beginning to melt. I immediately unplugged it took it outside. The smell of burning plastic stunk up my house. I feel there is an issue with these and they need to be addressed as they are in kids rooms across the country.
While cleaning my Vicks humidifier model VUL565 I found black mold growing in the tube.
Respondent reported that the smoke detector alerted the consumers of activity in their child's room, they discovered that there was smoke in the room which was emitting from the humidifier. The father attempted to remove unit but the base erupted flames, he had to use a fire extinguisher to contain the fire. This incident caused the area where the unit located to be burnt including carpet, padding etc. There were no injuries. Estimate property damages are $10,000.
We smelled a strong smell of an electrical fire and detected a bit of smoke in our upstairs also- the smell filled the entire upstairs. We quickly pinpointed that it was a humidifier that had automatically shut off days ago. The device was extremely hot and smelled like melting plastic. We believe that if we were not home, and given the time, this would have caused a house fire
We were using the Walgreens ultrasonic cool mist humidifier half filled with reverse osmosis water. It was on a low setting. I woke up to a strange smell and squealing. I thought it was running low and trusted the auto shut off feature to work. I was pinned down under a sleeping baby and could not check. In the morning, the light was off so I thought it turned itself off, despite a lingering hot plastic odor. I checked to refill it later and it was stuck to the box below. The motor had melted through the bottom, through the plastic lid of the box under it, and through plastic bags, burning the wool roving stored within. (Wool is very hard to burn). If the box had held flammable materials or the unit had been on the floor, I'm sure it would have caught fire and myself and two small children were in a bed right beside it.
Portable humidifier stick powered by [REDACTED] plug in melted the humidifier. I used the power cord that was included in the box and the whole thing burnt up and melted the product and the plug.
