Air purifier and operating method of the same

This invention describes a smart air purifier that protects its internal filter from damage. It uses various sensors to detect specific indoor situations like cooking, cleaning, or heavy pollution. When such a situation is identified, the purifier temporarily stops its air cleaning function and instead activates ventilation to remove the harmful elements, thus extending the filter's lifespan.

Why it matters: Since 2019, advancements in AI/ML algorithms and the widespread availability of IoT platforms have significantly simplified the complex sensor data analysis and real-time decision-making required for this system. This makes the "determining" step more robust and cost-effective to implement.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMultiple sensors, software logic, AI/ML system
