50 Pint vs 70 Pint Dehumidifier: Which Is Best?

50 pint and 70 pint are the most popular dehumidifier sizes in the market. You may be wondering buying which one makes more sense.

What are 50 pint and 70-pint dehumidifiers?

A dehumidifier’s capacity is measured by how much water it can remove from the atmosphere in a day. A 50 pint dehumidifier unit can remove 50 pints of water within 24 hours. Similarly, a 70 pint dehumidifier removes 70 pints of water a day.

Which dehumidifier is the best: 50 pint vs 70 pint

70 pint dehumidifiers are the best choice if the room’s area is close to the maximum a 50-pint unit is designed for. If the room size is smaller, choose a 50 pint dehumidifier.

Given below, I explain why this is so;

Choosing between a 50 and 70-pint dehumidifier can be tricky. The decision depends a lot on your preferences like price, quietness, energy efficiency etc.

In comparison, the dimensions and weight of both 50 and 70-pint units are very similar. Therefore, they are insignificant in this comparison.

So we are left with price, energy efficiency, quietness, and coverage.

Price difference

One significant difference between 50 and 70-pint units is the price. 70-pint units are pricier and this price difference can be anywhere from $50 to several hundreds.


Then there is the noise. Practically the noise levels of both humidifier sizes are not noticeable. However, let’s assume that a 70 pint unit is slightly noisier. Since you will have to run a 50 pint unit for more hours than a 70 pint one to achieve the same results for a given area, the 50-pint unit will make noise for longer hours than the latter.

Energy efficiency

70 pint units tend to have a higher energy efficiency than 50-pint units. Also, the 70 pint unit need to run only for shorter hours to achieve the same results as the latter. Therefore, in practice, a 70 pint unit consumes less energy than a 50 pint unit for the same square feet area.


This is the important bit in this comparison. All dehumidifier units have a maximum coverage area which will be specified in their spec sheets.

Let’s say a 50 pint unit can cover up to 900 sq. ft and a 70 pint can cover 1400 sq. ft.

So, if your basement area is 800 sq. ft, the 50 pint dehumidifier will have to work hard, at its peak performance, to dehumidify the area. But for the 70 pint unit, the same would be an easy job. Therefore, the life span of the 70 pint unit will be significantly more than that of the 50 pint one! So, in this case, it makes sense to go for the 70 pint dehumidifier.


If price is a big concern, go for 50 pint units as they tend to be cheaper in comparison. Otherwise, unless the coverage area is well within the 50 pint unit’s range, go for a 70 pint dehumidifier.
