Does the filter material in Xiaomi Smart Air Purifiers contain OIT components?

OIT (Octylisothiazolinone) is an organic biocide primarily used in coatings, paints, inks, lubricants, shoe polishes, leather chemicals, wood products, and conservation materials. It can cause skin and eye allergies and prolonged inhalation will harm human health.
If this biocide were used in air purifier filters, it could help kill bacteria and prevent mold growth. However, its components can be released into the air along with the purifier’s airflow, potentially causing allergic reactions in people.
All Xiaomi Smart Air Purifiers' filter materials do not contain OIT, so you can use them with confidence.
