【Junk Item】Futon Dryer Home Appliances

Purchased 3 months ago, but the warm air has become weak and stops midway. The power turns on as shown in the photos. The ozone function is working.
Only the main unit and hose were used; the rest are unused.
The aroma case was used with aroma oil, so please check the photos. There are 8 spare filters.
This is a junk item, so we would appreciate it if someone who can repair it would take it. M(_ _)m
