The Tjernlund UnderAire Series V1 Crawl Space Ventilator is designed to circulate fresh outdoor air underneath homes and porches. Excessive humidity levels in Crawl Spaces is the leading cause of premature rotting of support columns, joists, floors and beam supports. Humidity can promote fungus growth and increased termite activity. Humidity may also cause plumbing failures due to rust and corrosion. Constant operation helps vent radon gases, treated wood off-gassing and other odors that might migrate into living areas.- Excess moisture can cause mold, mildew and wood rot; under air fans increase air circulation to fight condensation

- 1-fan and small faceplate forventilation openings through brickfoundations (requires switch or dehumidistatto activate)
- 110 CFM to circulate fresh outdoor air underneath homes and porches

Works well but too expensive
Flavor Name: Mint, Size: 230 Count (Pack of 1)
We love these for nightime. Wish they didn’t stop making the cinnamon, but we like the mint anyway. Excellent for dry mouth esp at night! Too expensive though.

Enjoyed this book as one whom can relate to the healthcare maze. The "tip boxes" are really accurate and helpful for anyone to navigate the system and take ownership for the most desirable direction.
