Damp crawl spaces and basements can cause musty smells, condensation, damaged materials, and conditions that encourage mould growth. The Waykar 158-Pint Crawl Space Dehumidifier is designed for large spaces that need automatic humidity control and continuous drainage.
Waykar 158-Pint Crawl Space Dehumidifier — Best for large crawl spaces
The Waykar combines high-capacity moisture removal with a built-in pump, automatic defrost, and adjustable humidity control. Its commercial-style design is suitable for crawl spaces, unfinished basements, garages, and other demanding areas.
The advertised 158-pint capacity is measured under very warm and humid test conditions, so real-world removal will usually be lower in cooler spaces.
Pros
- Built-in pump and drain hose
- Automatic humidity control
- Auto-defrost and restart memory
- Compact commercial-style housing
Cons
- Heavy and relatively expensive
- Headline capacity uses high-humidity testing
- Who should buy it: Homeowners with large crawl spaces, unfinished basements, garages, or commercial areas that need continuous pump drainage.

FAQs
Does the Waykar need a floor drain?
Not necessarily. Its built-in pump can move collected water through a hose to a suitable drain or outlet.
Will it remove 158 pints every day?
The 158-pint figure is measured under unusually warm and humid conditions. Daily removal will normally be lower in an average basement or crawl space.
Can it help prevent mould?
It can reduce the humid conditions that encourage mould growth, but it will not remove existing mould or repair active leaks.
Can it be used in a finished basement?
Yes, but it is a commercial-style machine. A quieter portable home model may be more comfortable in a frequently occupied room.
How often should the filter be cleaned?
Inspect the filter regularly and follow the manufacturer’s maintenance instructions. Dusty crawl spaces may require more frequent cleaning.
What humidity level should I choose?
A setting between approximately 45% and 55% relative humidity works well for many basements and crawl spaces.
Final verdict
The Waykar 158-Pint Crawl Space Dehumidifier is a strong choice for large spaces that need powerful moisture control and automatic pump drainage.
Choose the Waykar 125-Pint model for better value, the Waykar 130-Pint model for improved efficiency, or the Waykar 80-Pint model for a finished basement.
The ALORAIR models offer practical lower-cost alternatives, while the AprilAire E070 Pro is the premium option for a permanent installation.
