I have an Humidex system in my own house and install them on a regular basis. I like the Humidex units because they do serve a purpose. However, if you have continued odor, I assume you still have active mold which means you have a leak, high humididty levels or moisture intrusion. A humidex will not cure your problem, only exchange the air so you will not notice the smell.

Did you have an inspection using a Thermal Camera? Often times when a source of moisture cannot be determined, we can identify an area using the camera. There are also times when a source of moisture is just from humidity and the camera would not help, but other equipment may.

Being in the mold remediation business, I notice that most of our competition will not or cannot determine sources unless they are visible. Did the "mold guys" that inspected your house use only visual inspection cues or used scientific equipment?

If you would like to have a Humidex unit installed, send me an email and I can help you out. The email below is not my business email. I purposely do not use my business contact information. I do not contribute to this forum to get business, but since you are local I would be willing to help you determine the source of the odor.

Unfortunately, b-dry sold you some bogus goods. The only way to prevent that moldy-odor is to seal any leaking foundation walls from the exterior...no sump pump in the world is going to stop water from entering your basement and allowing mold to grow.
