PURPOSE:To make the ceiling surface look neatly and more attractive and to easily replace a filter from below a ceiling. CONSTITUTION:An air purifier 1 is installed on a W bar 4 arranged on a ceiling 2. The air purifier 1 has an air filter 1b of an air purifying part 1a housed above a slit 4a formed by the W bar 4. The filter 1b is freely attachable and detachable from below the ceiling 2 through the slit 4a, permitting opening work, etc., of the ceiling 2 to be unnecessary, causing the air purifier to be easy to install. The air purifier 1 is hidden in the ceiling (above the W bar), causing the ceiling surface to look neatly and more attractive. The filter 1b is made nearly parallel to the slit 4a formed by the W bar so that the filter 1b may be inserted into the slit 4a and is arranged above the slit 4a. Therefore, the filter is easy to replace from the slit 4a, permitting the replacement work of the filter 1b to be easy. |
