What Size Dehumidifier for a 2,000 Sq Ft Space?

By the WhatSize editorial team 5 min read Standards-reviewed

TL;DR

For a 2,000 sq ft space, you need at least a 50-pint dehumidifier. For basements, very damp conditions, or high ceilings, go with 70 pints.

Why 2,000 Sq Ft Requires 50+ Pints

A 2,000 sq ft space is roughly the size of a medium house or a very large basement. At this square footage, a 35-pint dehumidifier is insufficient for all but the driest conditions. The AHAM standard calls for 30-42 pints of daily moisture removal at moderate dampness, which means you need a unit rated for at least 50 pints under the modern standard.

Frequently asked questions

What size dehumidifier for 2,000 sq ft?

A 50-pint Energy Star dehumidifier typically uses 400-500 watts when running. At the national average of $0.14/kWh, running 12 hours per day costs about $20-25 per month.

Will one dehumidifier cover a 2,000 sq ft house?

One dehumidifier can cover an open 2,000 sq ft space, but it won't effectively cover a multi-room house. For whole-house dehumidification, consider a whole-house dehumidifier that integrates with your HVAC system.

Should I get a dehumidifier with a pump for 2,000 sq ft?

A built-in pump is highly recommended for larger spaces. It automatically pumps collected water to a sink or drain, so you don't have to empty a heavy tank.
