Okay so in my apartments I tell the previous owner (I recently just bought them) that I plan on going in once a month and changing the air filter.This way the units can be inspected some and also I know the power bill won't be as high for the tenant and the low air flow won't burn out the fan motors faster.The seller mentioned to me that I should also check the toilets as well.The seller stated that tenants like to put those chlorox bleach tablets in the toilets and it eats up the flapper valves.This causes a water leak and runs up the water bill for the landlord.Here the water is included in the total rent payment each month.So should I ban the chlorine tablets from the toilets or should I just replace the flappers all at once??

This is a good system of venting until something (insualtion, birds, stuff in the attic) blocks off the airflow from the soffits.

When something isn't right with airflow, the pressure sensors disable things.

Some good info.I am looking at a REO with a bit of a mold problem and it looked like the kind that was caused by lack of airflow in a bedroom.

I'm telling you this because I am convinced we are getting the airflow we need from the soffit vents.

The panels might have been cut too short.They provide airflow, so the opening is adequate for airflow if it previously was sufficiently sized.

There is the coolness of the air and then the air flow.Is the air flow reaching all vents properly??

all the artwork is here though.) have the front and back doors be across from each other. light will shine all the way through as well as lovely air flow. go with a super pale gray on the walls and crisp white trim. merely sharing what has worked for me in the past; so this is all just food for thought of-course. 

I'd keep the screen doors as it means you can open the front door and get air flow in during warmer days without letting in the bugs. 

And whether you get infected depends on: (a) volume, (b) people, (c) airflow, and (4) time.
