50-Pint vs 70-Pint Dehumidifier: Which Size Do You Need?

By the WhatSize editorial team 5 min read Standards-reviewed

TL;DR

Choose a 50-pint dehumidifier for spaces up to 2,000 sq ft with moderate dampness. Go with 70 pints for basements over 1,500 sq ft, very damp conditions, or if you need faster moisture removal.

50 Pint vs 70 Pint: The Real Difference

The difference between 50-pint and 70-pint dehumidifiers goes beyond just the capacity number. A 70-pint unit is physically larger, uses more power, and costs $50-80 more upfront. But it can remove moisture significantly faster.

For most homeowners with a 1,500-2,000 sq ft basement at moderate dampness, a 50-pint dehumidifier is the right choice. It's more energy-efficient, quieter, and costs less.

Frequently asked questions

Should I get a 50-pint or 70-pint dehumidifier?

A 70-pint dehumidifier typically uses 200-250 more watts than a 50-pint when running. That's about $7-10 more per month.

Is a 70-pint dehumidifier louder than a 50-pint?

Generally yes. 70-pint units have larger compressors and fans, producing 55-60 dB compared to 48-53 dB for 50-pint models.

Can I use a 70-pint dehumidifier in a small room?

Technically yes, but it's overkill and may short-cycle, which is inefficient. A 70-pint in a small room will cycle frequently, wearing out the compressor faster.
