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.

We have been installing these for a while now and find them to hold up well and dry the crawl space out quickly and hold it at the desired level. like the ability to quickly add duct work if it is needed.

Only 5 days in and the unit has squeezed 35% humidity out of the air. Shooting for a final level of 55RH% and sure it can do it. Unit is surprisingly quiet. Just put it up on some blocks (about a foot from floor), plumbed drain to a condensate pump and plugged it in. No ducting - just as it was delivered. Seems to use about 700 watts when running.
This is in about a 2,300sqft crawlspace (about 42" average height, sand floor) after blocking off all vents with styrofoam blocks and sealing edges. House is in Delaware near the shore where it's very humid all the time (and we have wet lands about 45' from the crawlspace).

Recently bought an old house and had it renovated. Our builder sealed up the crawlspace, but didn't bother to tell us that we needed a dehumidifier in the crawlspace to keep the moist summer air from buckling the brand new hardwood floors and forming heavy condensation on the crawlspace HVAC runs. We live in middle TN and summers are horribly humid.
Installed a Mega Dry and it started to bring humidity down immediately. Noticeable difference within a few days. Hardwood floors started to relax after a couple weeks.
Easy to install, but heavy. Did it myself, including condensate pump. Really like this product. Thanks.

Had new AC and duct work installed earlier in year, after couple months floors started buckle and cup. I crawled under house and it looked like a rain forest with moisture coming off ducts and pudding. Sons came in Saturday and we laid 6 mil. plastic under house and installed CS70 dehumidifier, humidity went from 82% Saturday afternoon to 54% Sunday afternoon. still have a little work under house to seal some vents and drainage around footings to a sump pump. We hung CS70 from floor joists but had to install on concrete blocks because of vibration coming up to living area. I'm well satisfied with this product.

Good instructions, not much in getting it running and working. Only been up a day, so will see how it does.

Bought this to replace a failed unit in my crawl space. Within the first three weeks after install all signs of moisture is gone. As advertised it's very quiet, can't hear it running sitting in the room above where it's installed.

I have used this unit quite a bit lately. I do wish it had a more powerful fan. I'm not sure the 280 CFM is cutting it in some crawlspaces. Also need improvements on the water collection pan and discharge, the pan is flimsy and the area where the 3/4" fitting attaches to it has a weak spot that cracks the pan if you're not careful when doing the plumbing. It is cheaper than other units I have used in the past, but not quite as powerful. I use this one on smaller crawlspaces and larger ones that are going to require 2 units no matter how good the other brand I use is.

The MegaDry was easy to install and certainly moves a lot of air. The air in my crawlspace was significantly dryer after only a few hours of running the unit. I did run into some icing issues, but I think it was because I had the condensate drain improperly installed. Pay close attention to the instructions for installing the drain, I didn't think it was that big of a deal, but it did affect the unit's proper operation. Once I fixed the drain everything has been working great.
I emailed the staff at Crawlspace Depot about my icing problem and the drain. They responded quickly but referred me to the manufacturer. As I was researching the manufacturer online I found the same unit under another brand for $100 less with free shipping. Was a little peeved I overpaid by $100 and spent another $80 on shipping with these guys, but the unit works as advertised.
Based on a couple of the reviews I expected the unit to be quieter. It's fairly quiet, but I can hear it running from the first floor. The reviews sound like someone from Crawlspace Depot is writing them.
Also, in watching the installation video, I assumed it came with the straps to hang it from the joists in my crawlspace. It does not, you need to order them separately.

Our crawlspace was growing mold and mildew until I covered the vents and installed the CS 70 about 6 months ago. The difference was noticeable after about a week. Now, no mold is growing and the air is noticeably cleaner under the house. We will likely install one in the basement of our church as well.
