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

Note that you MUST install a hose to discharge the warm, moist air outside. The pics and descriptions are misleading because they make it seem as though you can just sit the unit in the space and turn it on; not so! That port claims to be 1.5" but in reality it is JUST larger than what 1" PVC fittings will adapt to. Oh, and it can only be 3.3 ft long (seriously?!?). You can also up to a combined total of 10' of duct work, but it has non-standard 5" flanges (U.S. stores stock either 4" or 6").

The dehumidifier worked great to keep my basement dry, until it totally stopped working less than 3 months later. I'm in the process of returning it.

I installed it in a 1,000 Sq. Ft. x 5' high cellar, sealed the foundation's air flow vents (dirt floor already covered with the standard heavy plastic) and vented the Ecor-pro to the outdoors, but it was not up for the task. The humidity in the cellar never reached below 66%. The second thing to know, is that Home Depot (and other hardware store I visited) does not carry any form of a 5" hose, vent, or pipe for the Ecor-pro's intake vent, and I had to Jerry-rig a hose for the 1.5" exhaust vent. Perhaps these are standard Euro diameters?

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.

This dehumidifier is extremely quiet, small, and effective. Since it's only a fan and a small heater, it should be substantially more reliable than compressor-based dehumidifiers. It's also nice to not need to worry about pumping or draining condensate; just gets ducted away as water vapor. The installation was easy. The most difficult part was poking a hole through my exterior wall for the exhaust ducting. The only disappointment I had with this dehumidifier is that it does throw some heat back into the space. I was hoping that 100% of the hot air would be sent outside. It runs cooler than a compressor-based machine, but it does heat the crawlspace up a bit.

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.
