I rated it all 5s simply because I have only had it installed for a week so i really can't say about durability or Quality but so far it seams to be doing a very good job holding my crawl space at 50 HR.

We've had a moisture problem in our 2,000 sq. ft. crawlspace for a long time and it's been getting worse - consistently over 75%. The Moisture Medic - 90 pint unit quickly brought it down to 50% and keeps it there - with very little noise in operation. We are almost right above it when it's operating and can barely hear it run. Plus, it's been very economical - adding little to the monthly utility bill. All in all, an excellent choice.

We only had Moisture Medic 70 for 2 months and it has exceeded our expectations. We are only dehumidifying 600 square feet. The insulation under the crawl space floor was drenched, you could ring it out like a T-shirt thrown into a bucket of water until we installed the Moisture Medic. The insulation was bone dry in 24 hours like it just came from the store. We have many power outages in our area and the Moisture Medic resets itself to the humidifying range you set it at when the power comes back on. Highly recommended.

It was an easy instally done in less than 15 min. Turned it on and moisture started down thw drain in the first 20 seconds. It's been a week now and it's a real work horse. Also installed the sump pump....both units work well. Great products.

 

Product arrived in 2 days. Just installed 2 days ago however it is performing awesome. I cannot comment in durability due to short usage however with a 5 year bumper to bumper warranty where can you go wrong. It is a genuine Aprilaire 1820. Very user friendly. Thanks again Crawl Space Repair.
