What the CPSC Data Shows
Air Purifiers (CPSC product code 307, in the Kitchen Small Appliances & Housewares category) generate an estimated 136 emergency-room visits every year in the United States, adding up to roughly 2,583 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 34/100 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 79% over the last five years, with the busiest year on record being 2024 (367 estimated ER visits) and the quietest 2008 (15 estimated visits).
The single most common ER diagnosis for air purifiers is internal injury to the head, accounting for approximately 508 visits across the 20-year NEISS window, followed by poisoning to the all parts body (262 cases). The 55-64 age group absorbs the largest share of injuries, about 620 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 5.1% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 43 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how air purifiers 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.

Honeywell Electrostatic Air cleaner in which we were using paper media and not metal cells caught on fire. Switch to cleaner in off position at time of fire. Air Cleaner, Cold Air Return and Gas Furnace damaged. All have to be replaced. Greenwood Heating & Air Conditioning doing a dx analysis for insurance said they have seen this problem before and now cut the power supply to the units.
I purchased the EdenPure Oxileaf II Plug-In Air Purifier August 1 2019. I gave it to my sister, for her basement, a few weeks later. Sunday (9/22/2019) she smelled smoke, went down stairs and saw fire coming out both sides of the Air Purifier. The fire was not from the electrical outlet. Fire was inside the unit. She said the unit was not hot to touch, and she was able to carry it outside with the fire coming out of the unit. EdenPure Oxileaf II Thunderstorm Technical Specifications. Model: A5941 Demensions: 5 1/8 in X 4 3/8 in X 2 in Weight: 9.7 oz Voltage Rating: AC 110-240 V/ DC 5 V Power: 6 W Ambient Noise 26 dB SPL to 34 dB SPL Recommended Room Size: Medium Ozone Concentration: 0.4 - 0.8 ppm Made in China I called EdenPure(9/24/2019), and was concerned they were not going to report this product issue, only replace the unit. They said I had to pay to send it back to them, because it was beyond the 30 day return policy, and under the 1 year warranty. I asked are they going to investigate this hazard and tell me the results. I did not feel comfortable that this would be done. I asked if they were going to report this to the Consumer Product Safey Commission, because if they were not I was going to. She put me on hold , then said she would send me a prepaid label to return the unit..I had to provide the box. I feel this product needs a thorough review to ensure it is not a fire hazard The unit states it shuts down every hour for a few minutes to prevent over heating. It states on the box 100% safe & Pet Friendly.
I was sitting in my living room when my air purifier made a weird sound, and then it started to smoke and smell like an electrical fire. I jumped up and quickly turned it off and grabbed my fire extinguisher, but it went out on its own. I ordered it in April; got it in in June; and it's now mid-September. I don't even use it all day--I always turn it off at night and when I sleep (I have a different air purifier from a different company in my bedroom), so it hasn't been used that long. Luckily I was sitting right next to it when it happened so that I was quickly able to turn it off and unplug it. I shudder to think about what could have happened had I been napping on the couch when this happened. I called the company right after it happened, Honeywell, but they said that they didn't manufacture it so I needed to call Kaz, which doesn't open 'til the morning. I bought it from Honeywell and it says Honeywell on the product, but I guess that's how things work these days. i asked to speak to a supervisor because I was concerned that they didn't have an emergency number for things like this, so that others could be warned right away. I also worry because I can't keep it for investigation. I live in an apartment building in NYC and so can't leave it outside safely or the evening to preserve for the company to test; I called my local fire department to see if maybe they could take it but they are only open for emergencies tonight. I don't feel safe keeping it in my apartment, even though the fire seems out. I just bought another one cause I thought it was great and it was recommended by my allergist, but I'm also nervous have it in my apartment, so I'm putting it out on the street as well.
I purchased a Honeywell Air Genius 4 Air Purifier at Walmart. I read all directions and operated the purifier as directed. Within 24 hours of turning the air purifier on I began to cough and had a tightness in my chest. I did not associate the symptoms with the air purifier until the next day. The coughing got painful, my chest and lungs felt inflamed, my sinuses felt burned. I searched the internet to see if there was any problems with using an air purifier when I discovered the ionic air purifiers have been identified for years to have caused similar symptoms, and are banned in some states. Why is there not warning labels required on these product? Why are they still for sale to the public? I took the produce back to Walmart and complained to the store manager and she said that there was nothing she could do to remove these dangerous products for there store and that it had to be removed by the manufacturer. How many more consumers have to have their lungs destroyed before this product is removed? It's now been over ten days since I stopped using the air purifier and all of the symptoms have remained. How many others have had their health effected because if these products?
Tabletop air purifying fan stopped working. We were using it to clean the air and make white noise to sleep. No injuries.

The consumer indicates that her and her children were in the room when she heard the air purifier was making noises and was also sparking. The consumer immediately moved her children to a different room, and when she came back, the unit was engulfed in flames. The consumer quickly grabbed a blanket, wrapped the air purifier in it, ran outside her home, and threw the unit in a metal dumpster. The consumer notes that there were damages to her familys clothes and shoes, as well as a blanket; everything totaling over five thousand dollars. The consumer contacted the Manufacturer and explained the situation; the representative she spoke to informed her that they would remove the product from the website, refund her the price of the unit, and reimburse her for the damages incurred however none of these things have happened. We were refunded not compensated. The consumer indicates that the air purifier was only used twelve to fifteen hours prior to the incident. Been promised by Amazon for 6 months that we would receive compensation for damages. Amazon removed all Toyuugo products on July 14th 202 6 months after the fire.
I am reporting a safety problem with the Holmes Small Room 3-Speed HEPA Air Purifier with Optional Ionizer, White. I purchased this purifier on March 14, 2016 and last week it caught fire. I have had this purifier in my 5 year old daughter's bedroom since it was purchased. Last Thursday when I turned the unit off in the morning, I heard it turn back on. I looked down and saw a spark flash in the top of the unit. The unit then started smoking. I quickly unplugged it and took it outside. Her bedroom smelled of burnt plastic. I have already thrown the purifier away but my husband suggested that I report it to Consumer Reports. Let me know if you have any questions. Below is a link to the product on Amazon which is where I bought it. Thank you. https://www.amazon.com/gp/aw/d/B0000DK35B/ref=oh_aui_i_sh_in_o0_img?ie=UTF8&psc=1
