PROBLEM TO BE SOLVED: To reduce loss due to flow velocity difference by balancing flow velocity of outlets. (EN) An air purifier in which the flow velocity of an air flow is balanced and the loss due to the flow velocity difference is reduced. [Solution] The loss was reduced by making the lateral width of the flap arranged at the position where the outlet flow velocity was slower to be the same size as the outlet and making the lateral width of the flap arranged at the position where the outlet flow velocity was faster than the outlet.
