Listing details to confirm

The listed coverage is “2000 square_meters,” while feature text separately claims coverage up to 2000 sq.ft. These units conflict substantially, so confirm the intended coverage before buying. Voltage is listed as both 100 volts and 240 volts, and the title’s 18L agrees with the stated 18 liters capacity.

The rating distribution is largely five-star with some four-star ratings, but that small sample cannot show whether the claimed runtime, coverage or humidity control performs as described.
