5 Criteria to Look For Before Buying a 70-Pint Dehumidifiers for Basement
Key buying criteria so you get the right fit the first time.
Pint Capacity vs Your Actual Room Size
Pint capacity describes how many pints of moisture a unit removes per day under standardized AHAM test conditions (65°F and 60% relative humidity), not necessarily your actual room. A 20-pint model suits a small, slightly damp bedroom, while a wet 1,500 square foot basement typically needs 45 to 50 pints. Check the manufacturer's stated square footage coverage against your specific room size and dampness level, not just the pint number alone, since a 'wet' room needs meaningfully more capacity than a 'moderately damp' one at the same square footage.
Drain Hose vs Pump vs Manual Tank
How a dehumidifier gets rid of collected water matters as much as how much it collects: a gravity drain hose is the most reliable option but needs a nearby floor drain or lower elevation to work, while a built-in pump can send water uphill to a sink but adds a component that fails more often than a simple hose. A tank alone requires regular manual emptying, which quickly becomes impractical in a genuinely wet space running around the clock. Check your room's actual layout for a nearby drain before assuming any drain method will work as advertised.
Compressor vs Desiccant Technology
Compressor (refrigerant-based) dehumidifiers work well at typical room temperatures but lose efficiency below about 65°F and can ice up below 40°F, making them a poor fit for an unheated garage or cold basement in winter. Desiccant dehumidifiers use moisture-absorbing material instead of refrigeration, running effectively in cooler spaces where a compressor model would struggle or ice over. Check your space's typical temperature range, not just its humidity level, before choosing between the two technologies.
Tank Size and How Often You'll Empty It
Daily pint removal and tank capacity are two different numbers that both matter: a unit rated to remove 50 pints a day but with only a 10-pint tank will need emptying multiple times daily without a drain hose connected. Check the actual tank size specifically if you don't plan to use continuous drainage, since relying on manual emptying in a genuinely wet space quickly becomes impractical with a small tank.
Auto-Restart and Humidistat Control
An auto-restart feature resumes operation automatically after a power outage, important for basements and crawl spaces where you might not notice the unit stopped for days. A built-in humidistat lets you set a target humidity percentage and the unit cycles on and off automatically to maintain it, rather than running continuously and over-drying the air or wasting energy. Check for both features specifically if the unit will run unattended in a space you don't check daily.

How We Evaluated These 70-Pint Dehumidifiers for Basements
Each pick was assessed across 5 criteria weighted for real-world use.
Pint Capacity vs Your Actual Room Size
Pint capacity describes how many pints of moisture a unit removes per day under standardized AHAM test conditions (65°F and 60% relative humidity), not necessarily your actual room.
Drain Hose vs Pump vs Manual Tank
How a dehumidifier gets rid of collected water matters as much as how much it collects: a gravity drain hose is the most reliable option but needs a nearby floor drain or lower elevation to work, while a built-in pump can send water uphill to a sink but adds a component that fails more often than a simple hose.
Compressor vs Desiccant Technology
Compressor (refrigerant-based) dehumidifiers work well at typical room temperatures but lose efficiency below about 65°F and can ice up below 40°F, making them a poor fit for an unheated garage or cold basement in winter.
Tank Size and How Often You'll Empty It
Daily pint removal and tank capacity are two different numbers that both matter: a unit rated to remove 50 pints a day but with only a 10-pint tank will need emptying multiple times daily without a drain hose connected.
Auto-Restart and Humidistat Control
An auto-restart feature resumes operation automatically after a power outage, important for basements and crawl spaces where you might not notice the unit stopped for days.
How to Choose the Right 70-Pint Dehumidifiers for Basements

|---|---|
| Small room, slightly damp | AIRPLUS Dehumidifier for Basement |
| Standard room or moderate dampness | AIRPLUS 4500 Sq Ft Dehumidifier for Bedroom |

Drain Hose vs Pump vs Manual Tank
Continuous drain (e.g. AIRPLUS 4500 Sq Ft Dehumidifier for Bedroom)
Runs hands-off near a floor drain, the most reliable option if your space has one nearby.
Manual tank emptying (e.g. AIRPLUS Dehumidifier for Basement)
No drain needed, but requires regular emptying, more practical in a less humid space.
Match the drain method to whether your room actually has a nearby floor drain, not to which sounds more convenient.
By Technology: Compressor vs Desiccant
| Priority | Recommended pick |
|---|---|
| Standard room temperature | AIRPLUS 4500 Sq Ft Dehumidifier for Bedroom |
| Cold, unheated space below 65°F | Look specifically for a desiccant model |

Look for
Auto-restart after a power outage and a built-in humidistat, since these spaces often run unattended for days at a time.
In this comparison
AIRPLUS 4500 Sq Ft Dehumidifier for Bedroom is worth checking against its specific auto-restart and humidistat spec before assuming any unit handles unattended operation well.
When to Spend More
Spend more if
You're covering a large or genuinely wet space and want a built-in pump and higher capacity, where Waykar 80 Pints 5000 Sq. Ft 2025 Energy Star Dehumidifier for Basement justifies the extra cost.
Save if
You're covering a small, moderately damp room, where AIRPLUS Dehumidifier for Basement already covers the job at the lowest price here.
Frequently Asked Questions
What size dehumidifier do I need for my room?
As a rough guide, a 20-pint model suits a bedroom or space up to about 1,500 square feet if only slightly damp, while a genuinely wet basement of similar size often needs 45 to 50 pints; match the manufacturer's coverage claim to both your square footage and how damp the space feels.
Should I get a dehumidifier with a pump or just a drain hose?
A gravity drain hose is simpler and more reliable but needs a nearby floor drain or lower elevation to work, while a pump can send water uphill to a sink, which matters most in a basement with no nearby drain; check your room's actual layout before choosing.
Can I use a dehumidifier in a cold garage or basement?
A standard compressor dehumidifier loses efficiency below about 65°F and can ice up below 40°F, so a genuinely cold, unheated space needs a desiccant model instead, which keeps working effectively in cooler conditions.
How often do I need to empty a dehumidifier's tank?
It depends on both the tank size and how much moisture your room actually produces daily; a small tank under 15 pints in a genuinely wet room can fill multiple times a day without a drain hose connected, so check tank capacity specifically if you're not running continuous drainage.
Is a bigger dehumidifier always better?
No. An oversized unit for a small room can over-dry the air and waste energy cycling on and off more than necessary; match the pint capacity to your actual room size and dampness level rather than buying the largest model available.
Does a dehumidifier help with mold?
Yes, keeping indoor humidity below roughly 50% meaningfully slows mold growth, but a dehumidifier addresses the humidity that feeds existing mold, it doesn't remove mold that's already present, so active mold growth still needs direct cleaning or remediation.
