After researching many dehumidifier, this one was at a great price 119.00, with humidity sensor.
My new semi-detached house has damp appearing on walls downstairs and upstairs (detached side) including a musty smell in the hallway
When I put it on it showed 70% humidity and I could even shut my wooden inner front door. After 2 weeks at having it on during the day, humidity is now 45% and front door shuts/opens no issue.
When you put the dehumidifier on it tells you what humidity is in the room, you then press the humidity button to set your desired humidity between 30 and 40%.
I have ordered another one to use in my living room due to my open plan kitchen as the windows are steaming up. I am happy with my purchase.
