Anywhere with this Dehumidifier by Alorair

The Sentinel HD55 is the perfect device for crawl spaces and basements. With an updated compact design and size, this unit could be easily installed in a low-clearance crawl space or tight basement. Don't be fooled by its appearance; it can remove up to 120 pints at saturation (55 PPD at AHAM). Moisture remains the greatest threat to your home’s structural integrity. Increased indoor humidity levels could cause the growth of mold and mildew and an increase in dust mites, all of which are known allergens that could cause respiratory problems and asthma. This is why you should invest in a dehumidifier today!

Suitable for basements and crawl spaces

Designed for modern homes, the Sentinel HD35P dehumidifier can quickly and efficiently remove 70 pints of moisture per day at saturation, up to 1,000 square feet. With GLGR technology, you'll save 30% energy with precise humidity control, granting us the Energy Star certification!
