Air Purifier cum Dehumidifier and Ionizer

We have an air purifier which doubles up as an ionizer and dehumidifier in our bedroom. My lips used to get really dry every night in the air-conditioned bedroom but with the air purifier cum dehumidifier switched on, I don’t get dry lips and throat anymore. I think this gadget is really well spent and is a good investment. I may buy another unit for the girls’ bedroom too if the price of the air purifier cum dehumidifier goes down.
