50 Pint Portable Commercial Desiccant Dehumidifier for Whole House, Bedroom, Bathroom, Crawl Space, Basement and Garage

I purchased this unit in mid September 2020. Where we live the humidity is never stifling but consistent throughout most of the year between 40-80% (summers being the highest relative humidity. We have a fully built out (Including closed cell foam insulated) lower level living area where two walls are under ground and two walls are above ground. It has three doors; to garage, to outside, to main living area upstairs. We keep all closed most of the time (unless it’s dry and warm outside) as we have a dual zone HVAC system managing that area. The HVAC keeps the lower area “OK” but struggles in summer months to keep dry without causing more mildew with the cooling air and high dew point. Total area about 500 sf. I decided to get the desiccant dehumidifier because the water tanks, pumps. and all that stuff for a standard system is a pain and a hassle to maintain. I went with the larger unit here to handle this area "no problem” vs. coming close to max space of this company’s smaller unit. The installation was fairly easy. The only drag (which I knew I was doing prior to purchase) was drilling through brick facia, concrete block, and the inner walls for the exhaust. The 1.5” PVC tube is a simple, non-water forming warm air exhaust that works great without anything leaving the room except humid air. Because the unit has been working while outside the worst months of humidity here are past and since it’s still early in our ownership, the decision to rate this 5 stars is pending. However, thus far, the unit has worked great. It’s one-speed fan is about as noisy as a regular box house fan on with a setting of medium or high. It ran for about 10 days straight 24/7 dropping the humidity from inside the area. Humidity at start was 74%. I have the dehumidifier set to ~50% now and it runs a couple of times as day to keep it low. The range before it kicks on is about 2-4% from the set point. The area is finished in almost all wood accouterments comprised of mainly Brazilian and North American Black Walnut so I had expected a long initial drying period. Thus far the unit is working great. We are hoping this was a great investment long term as this living area especially when we have guests down there is now very, very comfortable (includes a full bedroom). The HVAC works very little now and the area is super dry.

Great for basement, do not need to hook up to ventulation system. I installed it as a standalone unit. Humidity levels dropped significantly in 24 hours.
