In hot and humid climates, homes with basements or crawl spaces particularly need dehumidification to prevent mold from growing in the floor joists and subfloors. When mold grows unimpeded here, it can easily contaminate the air inside the home. No matter how many precautions you take inside the home, allowing hot and humid air to come into contact with subfloors that have been cooled by air conditioners will create the right conditions for growing mold. It is for these reasons that we proudly offer the MEGA DRY CS70 Dehumidifier, a powerful system designed specifically to fit into even the tightest spaces.
This amazing unit provides the dehumidification necessary to dry out even the wettest crawl space, removing up to 70 pints of water from the air each day in a closed crawlspace of up to 3,000 square feet. With a high efficiency filter, this unit cleans the air, removing mold spores and preventing future mold growth. The CS70 is also up to 40% more efficient than a stand-alone dehumidifier, saving you money right away. And it's easy to use, too. With a variety of installation and control options, including whole house ducting, operation can be as simple as setting the humidistat. Because the unit is permanently drained there are no buckets to empty or daily maintenance requirements, just dry, clean, healthy air, protecting your health and property.

I just bought my first MegaDry CS70 for a large crawlspace/basement encapsulation project (approx 2,000 sq ft) and I found the product to exceed my expectations. I deliberated over going with the larger, more expensive SaniDry unit (MSRP $1399), but went with the MegaDry based on Crawlspace.com's strong recommendation.
In no particular order here is what has impressed me about this unit:
- excellent air cleaning capability. This is one of the first things I noticed. When I turned it on the first time there was a lot of dust in the air and within minutes it was gone. I have allergies and have already noticed a marked improvement in air quality throughout the house.
- very efficient dehumidification capability. I was impressed with how fast it brought the RH down from 70% to 50% and it has maintained it +/- 1% RH since being put in operation.
- the unit is very quiet. I have it located in the crawlspace and I cannot hear it on the first floor when it runs.
- ease of installation. This unit is not so heavy that one person can't install it which is nice. It can be hung from the joist or just sit on the floor. Having the option of either side for the condensate return is nice also. Lastly, installing the optional condensate pump was a cinch.
- customer support. I initially thought my unit had a humidistat issue and so I called crawlspace.com. I was given the number for the supplier's customer support line and within minutes I was talking with a knowledgeable tech who then shipped me the needed parts.
Bottom line, I highly recommend this unit.

I was surprised to find it raining under my house due to humidity and condensation from my HVAC duct work. Insulation had to be removed and HVAC ducts replaced. Sealed up crawl space and did encapsulation myself and installed Mega Dry CS70. It works great. This machine dried my crawl space out quickly. Only issue I experienced was with the plastic drain pan. Drain pipe got hit during insulation removal and cracked the plastic drain pain. Crawl Space Depot's staff was helpful and repaired my unit quickly and affordably. Wonderful people and great customer service. I highly recommend the Mega Dry CS70 and Crawl Space Depot to anyone.

So far our company has purchased and installed two of these dehumidifiers in crawl spaces. They are compact and easy to install. We choose to hang them from the floor joists so the condensate will gravity drain without any problems. The 8" duct connections are sized properly for 8" flex duct. The auto-restart works great and the humidistat seems to be accurate. I like having the option to run the condensate drain from either side of the unit. Our installer accidentally overtightened the drain pipe and cracked the plastic drain pan inside the unit. Crawlspace Depot shipped us a replacement pan immediately. Another big plus is the homeowner's claim they don't hear it running. So far, this is an excellent unit for the money.
