10 Best Crawl Space Dehumidifiers

Best Crawl Space Dehumidifiers

You might not think a lot about the small spaces in your home, but you should. Crawl spaces are famously damp little dark spaces in the house that are left behind for electric wires, pipes, or duct-work. If the humidity levels in these small pockets of space are left unchecked, it could easily cause rot, mold, and bacterial infestations, not to mention wreak havoc on your home’s structural foundation.

The solution? Getting a Crawl space dehumidifier, of course. You’d be forgiven for not knowing a thing about them; most people don’t. What’s certain is that you do need a dehumidifier for your Crawl space and basements.

#10 BaseAire AirWerx55 Crawl Space Dehumidifier

The AirWerx55 Crawl space dehumidifier is slightly smaller (and lighter) than your typical Crawl space dehumidifier. It’s designed to handle up to 1,300 square feet and includes features like HGV defrosting (allows it to work efficiently in low temperatures) and remote-controlled functions.

The dehumidifier is capable of generating 55 pints per day (PPD) at AHAM, and 125 PPD at saturation. This water is expelled via continuous gravity draining through a 6.5-foot drain pipe, so you don’t need to have a pump.

It comes with a nifty digital touch control panel where you can track humidity levels. This is also where you can access stats and information from its in-built humidistat. Other features include noiseless performance, coated coils, auto-error detection, dent-resistant housing, and auto-restart after power interruptions.
