This unit does not clear out cigar smoke as well as I thought it would
We purchased four humidifiers and are very happy and satisfied with our purchase.
Do you fill the manual feed model with distilled water only, also will I need an RO unit for the auto feed version?
Yes, use distilled water only for manual feed and an RO water filter for the auto feed version.
What is the difference between auto and manual?
Manual water feed requires you to add water manually and auto water feed need a filtered water line connected to the humidifier. Auto fill humidifier will have a connection on the humidifier for water line feed.
