Posting this video to help others who are planning to buy one e.g. a second hand one from carousell/ ebay.
Before you pay, make sure you ask the seller for these:
1. photo of the power on switch
2. video of the filter cover snapping close. This is to test that the magnetic closure is active
3. photo of wire
