I blew my back out at 28 years old had to have a lumbar surgery. 

All dry food stuff is sealed in packaging and plastic containers.

There are other options, like adding a small vent fan to vent the crawl space to the outdoors, putting a dehumidifier in the crawl space, and having the crawl space "sealed" - basically spreading out big sheets of plastic on the ground and running them up the inside walls.

Often this isn't a paper throwaway filter like a central A/C has, but a section of wire or plastic mesh in the front grille that you can pull out and wash. 

They have industrial fans running in multiple rooms including the bedroom, kitchen and hallway and they are sectioned off with floor to ceiling plastic.

They may include painting the rooms for example but not to repair the plastic or to tape off the trim or scrape / clean walls.

The fan blade is relatively thin aluminum (older models) or plastic (newer), so don't go crazy when cleaning it.Tip: If you take the cover off, put the screws in your pocket, or put them in a plastic bag up on the kitchen counter. 

Prior to having to go on this program,   due to having had a newborn baby boy,  Whom had to have multiple surgeries within the first few weeks of his life, I was a *Typical Renter* and had never even heard of the Program before,  in fact the Hospital staff introduced me to the program, as I had basically lost everything from having to stay in Baltimore at the Ronald McDonald house to be close to my son for a rather extended period of time...

It's like debating various surgery options before diagnosing the patient.Money saved on taxes from selling his rental can only be rolled into an investment property, and he is looking for money to fund his residence.
