I haven’t seen this very often but we had a customer ask us to install this a few weeks ago. After a little research, it looks like Cedar removes moisture from the air, so in humid climates, it will act as a natural dehumidifier and keep your clothes from developing mildew. If you like the smell of Cedar, it will keep your clothes smelling fresh. Cedar oil may repel moths at high concentrations but Cedar Lumber loses most of its oil a few years after cutting. Just because you can smell the cedar in your closet does not mean moths will be repelled by it.
