A growing body of evidence has indicated that its airborne exposure can induce severe lung injury. However, there has been low awareness of other health outcomes in HD users. This study aimed to evaluate health conditions appealed by claimants for compensation in relation with an increased exposure to HD.  \nMethods From survey data of personal HD exposure assessment of claimants for compensation in Korea, we included a total of 4,179 subjects [cases in each dataset were defined by nine reported health conditions, i. e., pneumonia, asthma, cardiovascular disease, respiratory disease, otorhinolaryngologic disease, brain disease (includ‑ ing cerebrovascular disease), dermatological disease, lung cancer, and all cancers] . HD exposures was considered as the following exposure criteria: exposure duration, exposure proximity, exposure direction, chemical type, cumula‑ tive exposure time, indoor air concentration, and cumulative exposure level. Logistic regression models were used to evaluate the associations between HD exposure and health conditions.  \nResults After adjusting for sociodemographic and health behavioral factors and other chemical exposures (house‑ holds, environmental, and occupational exposures), an increase in cumulative HD exposure time was significantly associated with risks of all nine diseases (all p‑trends \u003C 0. 05) . An increase in HD exposure duration was associated with asthma, respiratory disease, otorhinolaryngologic disease, dermatological disease, all cancers, and lung cancer (p‑trends \u003C 0. 05) . Indoor HD concentration was associated with only pneumonia (p‑trend = 0 . 015) .  \nConclusions Our findings suggest that cumulative exposures to airborne HD might potentially increase the risk of various reported health outcomes.  \nKeywords Humidifier disinfectant, Humidifier disinfectant exposure, Reported health conditions  \n†Myeongjin Hong and Min Jae Ju are equal contributors to this work as co‑ first authors.  \n*Correspondence: Yoon‑Hyeong Choi [yoonchoi@korea.ac.kr](yoonchoi@korea.ac.kr)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2023.
