Greatly improved efficiency of my 90 pint dehumidifier. Can hardly tell these are running when under crawlspace.

Excellent. I have installed these fans in the past to remove crawlspace odors for encapsulated crawlspaces. I discovered that I had a 88 avg. level of 7 picos in my basement. I ordered this fan and connected it to our 88 pipe. Within 48 hours our 88 average level is now 1.1. Awesome. Easy to install, quiet, and it works! This company is also a five star company to work with.

Website information made it clear that I should add circulation assist to the Moisture Medic purchased. My main reason was to “balance” the humidity in our 1,850 sq.ft. area. Our home has a lot of piers and is not a wide open square. Using a few hygrometers I noticed a couple of areas in the space where the % was higher or uneven throughout. This fan kit seems to have helped with circulation of the air.

Glancing over the installation instructions at first seemed very confusing but if you will follow the written instructions line by line it will make sense and go without a hitch.

I also added some ductwork to inlet and outlet of dehumidifier to assist in directing the airflow so that I get a better circular movement of conditioned air. Very happy with results.

I had my crawl space encapsulated a year ago, and several months later I started noticing a strong odor after a hard rain. The odor would work it way through the air vents into the living space. I called Larry after reading his blog on the web, and he suggested this fan. I installed about 65' of thin wall pipe under the plastic on the ground and vented it out of an existing vent. The smell was gone within 12 hours! I also like the fact that it comes with a 5 year warranty. Thanks!

Ordered two fan packs, and they arrived in 2 days. Instructions were clear and the fans and wiring with transformer installed quickly without any problems. Called the tech line with one question and they were super friendly and helpful. The fans are extremely quiet and perform the job well. It is a pleasure doing business with this company!
