Kara Zorn on May 5, 2014 7 Comments Deciding on a dehumidifier can certainly be a difficult task. Not only are there many different brands and types to choose from, but dehumidifiers also tend to throw people off by use of a pint rating, in reference to models. Most know what a pint is and can visualize it but have a hard time understanding the real difference between dehumidifier models with different capacity ratings; say, a 50 pint dehumidifier versus a 70 pint dehumidifier. More importantly, the trouble lies in understanding which one is right for you and your needs. What is a “pint” in dehumidifiers? A dehumidifier’s pint capacity is the amount of moisture (in pints) that it is capable of removing from an area in a 24-hour period. It is important to remember that a dehumidifier’s performance can be affected by both the size and humidity level of a given area. In general, a dehumidifier with a pint capacity rated at 70 pints or less is best for residential use, while dehumidifiers rated over 70 pints are ideal for commercial or industrial applications. Now, to determine which one is right for you… Dehumidifier Pint Capacity Chart The below chart will help you determine how many pints your dehumidifier will need based on the type of room you are trying to dehumidify and how damp the room is. Small to Medium Bedrooms: Areas That Are Damp — 41 Pints or Lower Areas That Are Very Damp — 41 to 59 Pints Garage: Areas That Are Damp — 60 Pints or More Areas That Are Very Damp — Industrial Dehumidifiers Are Recommended Living Room to Large Bedroom: Areas That Are Damp — 41 to 59 Pints Areas That Are Very Damp — 60 Pints or More Bathrooms: Areas That Are Lightly Damp — 40 Pints or Lower Areas That Are Very Damp — 41 to 59 Pints Basement and Crawl Space Areas That Are Damp — 60 Pints or More Areas That Are Very Damp — Industrial Dehumidifiers Are Recommended

Bob Pannemann says August 10, 2017 at 3:36 pm My humidifier seems to have lost efficiency’ When I removed from crawl space and cleaned it up I measured performance over 8 hours of running – 9 pints in an 42 % RH.at 76 deg F, This didn:t seem too bad. I am going to return to crawl space and see what happens , What should I expect in the crawl space at 50 RH and 70 deg F? Reply

joanne stevens says June 1, 2018 at 3:56 pm My dehumidifier runs constantly, but the water bin does not collect any water. I recently cleaned the filter for the first time since purchasing the dehumidifier. I also cleaned the rest of the dehumidifier. Why won’t it collect any water, even though the fan is running? Reply
