Q1) Any filter part need to change after 1 year?

A1) Yes. Generally, its recommended to change the filter every 3k hours. Outer particle filter needed to be cleaned in a weekly basis to ensure smooth flow of air into the system.

Based on daily usage of 12-15 hours, the interval of changing new filter is approximately 4-5 months . If pollution is worsen in some areas such as nearby to the industrial area, the lifespan of filter will be shorten too.
