What Size Dehumidifier Do I Need?
What size dehumidifier do I need? Figuring out just what size dehumidifier you need can be a bit annoying, we know, and unfortunately its not as straight forward as you might hope. You can make a guess at it yourself generally by assessing the room size, but the more important thing to take note off is just how much moisture your need to remove or how high your humidity level is, as well as your current situation.
For example if you have a recurring source of damp, then the most powerful you can afford with a high pint intake is the best possible decision to make regardless of room size. Basically, the higher the humidity, the higher pint size you want.
Our general rule of thumb for room type and location goes by the following:
Bathroom or Living Area: 25-30+ Pints
2nd Floor/Above Ground Rooms: 30-40+ Pints
Utility or Basement: 50-70+ Pints
Multiple Rooms/House-wide Humidity Problem: 60 Pints Upwards to a Whole House Dehumidifier
Warehouse/Large Storage Area/Commercial Area: Commercial/Industrial Dehumidifier
Our general rule of thumb for room/area size goes by the following:
400 square feet: 20-30+ Pint
800 square feet: 35-40+ Pint
1000 square feet: 50+ Pint
1300 square feet: 65+ Pint
Bare in mind though, this does not apply to every persons situation. The above square footage suggestions are based on non coastal areas, if you are living in a coastal area then you can expect that coverage to decrease by as much as 50%. Ultimately the best course of action to take is to assess just how high your humidity level is and what size area you need to dehumidify.
It is always the best decision to purchase a larger pint dehumidifier than you may think you need. Why? First, it will dehumidify the air a lot faster over the same amount of area. For example a 70 pint will remove the moisture in the air a lot more efficiently than a 50 pint in the same area. And second it will save you money, purely because if you use a 40 pint in a high humidity basement that requires 50 pints to be removed for example, it will be cycling on and off on and off, running constantly playing catch up; increasing your energy consumption. Not to mention bigger is always better, the higher pint sizes are more than often much more energy efficient than smaller sizes.
A Good Middle Ground
If you’re not looking for dehumidifiers for a basement or utility room, or if you are just not sure, then around 40-50 pints is a good middle ground to settle on. If worst comes to worst and you want to buy the best and highest pint rate possible, you simply have a more powerful dehumidifier that’s future proof and capable to cater for any problems that may escalate further down the line, and remember bigger is always better and more efficient. And if its energy star rated, you wont have to worry about that extra power costing you.
Where Is The Best Place to Buy A Dehumidifier?
We often find that Amazon always have a great range of dehumidifiers in all shapes and sizes, as well as being cheaper than the manufacturer themselves in some cases. The link below will take you to a list of Amazons best selling units.
How Would I Assess My Humidity Problem?
The easiest way to do this would be use a humidity meter or otherwise known as a Hygrometer. If you dont own or want to have to purchase a hygrometer then the other way is to simply keep an eye out for symptoms of excess moisture. Take a look at our Humidity and Moisture page HERE for the symptoms and problems. If you do wish to purchase a hygrometer, then we recommend this one.
Whole House Dehumidifiers
If you have multiple rooms, and deem that your home is suffering from high humidity as a whole, and you wish to dehumidify your entire house rather than particular rooms, then we recommend a Whole House Dehumidifier. They are by far the best option to take to combat your entire house’s humidity problem.
