space should be left around the purifier to avoid
the blockage of breeze.

caused by damp inside the purifier, however it
does not affect normal operation.

alkaline batteries are recommended.
Note* batteries should be changed every 6
month for best performance

inner parts, do not immerse the purifier into
liquid.
