How Can You Tell the Best Crawlspace Dehumidifier From All the Rest?
Choosing the correct dehumidifier for your crawlspace can be so confusing because there are many different brands, types and sizes of dehumidifiers. When dealing with crawlspace moisture, it is important to choose a unit that is made specifically for use in crawlspaces.
The unique thing about your crawlspace that makes it completely different from any room in you home, is that humidity levels are always greater down there and temperature is always colder than any other room above in the main part of your house. That’s why you find mold growing down there before you see it anywhere else in your home. The colony starts below your house and sends its spores airborne, to float up, into and throughout your home until they find a moist place to grow. Drying out crawlspace moisture with the correct dehumidification equipment is the most direct way to solving many air quality issues in your home. And because of the unique conditions in your crawlspace, only a unit specially equipped will function properly down there.
We performed a study to determine the BEST VALUE in the product class of crawlspace dehumidifiers. We compared products side-by-side in simulated crawlspace conditions.
At the conclusion of our testing and product reviews, we chose to produce an unmatched line of crawlspace dehumidifiers, custom made to our specifications that will provide ideal performance in your crawlspace environment. We call these the Dri-CrawlSpace® COMPACT and Dri-CrawlSpace® PLUS available only on this website from OscarAir. The primary difference between the two models is the amount of moisture they can remove from the air. The Dri-CrawlSpace® COMPACT can pull 31 pints of water per day from the air, while the Dri-CrawlSpace® PLUS can remove 51 pints per day. Refer to the chart on our blog “How to Size a Crawlspace Dehumidifier” to determine the right size unit for your crawl space.

As you may have learned from our series of informative blogs, the American Lung Association and the American Medical Association recommend that your home maintains a relative humidity level of 30% – 50%. Using a properly sized dehumidifier with a vapor barrier will protect your health from mold and dust mites and will protect your home from the devastation of wood rot and termites.

High quality commercial grade crawlspace dehumidifiers like the Dri-CrawlSpace® COMPACT and PLUS when used in crawlspace conditions, will outperform any Energy Star rated appliance grade dehumidifiers found in local retail stores. Those cheap units are not made for harsh crawlspace demands and environments. Their compressors will become over-worked and will cause your electric meter to spin fast enough to slice ham. To make sure you are getting a unit that will work in your crawlspace, check the operating temperature. Don’t be fooled by dehumidifiers that advertise Energy Star efficiency at 80°F. Go with a dehumidifier built for low temperatures found in crawlspaces. And here’s the kicker – our Dri-CrawlSpace® units come with a performance guarantee. If it does not solve your humidity problem, you get 100% of your money back. Just call 1-800-564-0667 to activate your Performance Guarantee. A technician will revue your situation to ensure you are getting the right equipment and give you your activation code. Then order your unit online by clicking BUY-NOW in the menu above.
