Ouch, Luna, that's a dilemma! I am not sensitive but even so, outgassing is bothersome to a LOT of people (me included---I just dislike that smell, ugh!)....

If you can afford a couple of room-sized hepa fitlers, or "air scrubbers" as I have heard them called, that may help. Also wash walls and all else in any solution that doesn't bother your sensitivities---an in-law said that really helped when they moved to a new place that was, like yours, in a place that was that new-built.

Otherwise, I do think if it's that much of a chance, it may be worth it. As for dust... hmmm.... what kind of air filters does the HVAC have or use? We use the super-good filtretes and change once a MONTH. Even tho' manufacturers and landlords say once every 3 months (or once a year if they're cheapo landlords), we find that changing monthly is a huge help with hubby's regular old allergies and with dust. So if you can change out something like that weekly for the first month or two maybe? I Know it's pricey, but these are the only things I can think of, I'm sorry.

Good luck!

Great advice here from Leo.

I think you would have to deal with the dust till the time construction is completed. I would recommend you to try and complete interior work of your house. I had experienced all of this that to in harsh winter. If you want to continue reading visit [url=http://www.kevinbradleyrealtor.com/]my blog[/url].

Can the house can be cleaned until completed? Gerad has a good idea if this is possible. I know ppl who have finished sections of the house and basically close the door on the construction zone. Wishing you the best!

You could probably rent an air scrubber or HEPA Filter for home depot, Lowe's, Sunbelt, United rentals, construction rental place for a month instead of buying.

Hi Luna. I can empathize with your predicament. Over the years, I've developed multiple chemical sensitivities and have had to modify my home as much as possible. Good suggestion on the air filter. There are air purifiers on the market now that help filter chemicals. You can look for ones that say they reduce VOC's (in carpet, paint, etc). Things like opening windows and running fans can help speed up the off gassing. Vaccuming with a HEPA filter can help some. It can also be helpful to have the carpets cleaned. Many companies now offer non toxic cleaning processes. You probably would want to not be there when it's being done and ask that the windows be opened during the cleaning. Also, AFM Safe coat sell products that "seal in" the chemical to prevent off gassing and the used to have a product just for carpets. I think I remember it being a three step process. They have a website but you can also find their items at Green Building Supply online.
The first several months are the worst. Is it an option to wait a little while before moving in?

Hope this helps in some way. Hugs...

Apologize if link doesn't work. Have trouble with that sometimes with my smart phone ;)

Yes, HEPA filters will help, you can also steam clean the carpets, to help with out gassing. The smell of the new carpet is a solvent that is used when putting on the latex backing of the carpet, I cannot stand to be in a room with new carpet, I start getting a headache right away...
One of the main chemicals is 4-phenylcyclohexene. This chemical is also found in water and oil based base paints.

A cheap solution for air purifiers; go to Homedepot or Lowes, buy a $16.00 box fan, they also sell HEPA filters for forced air furnaces, 20"x20,x1" for $22.00, you then duck tape it on the inlet side of the box fan, Walla! A cheap air purifier! I did this, it works as well as the fancy ones, and is a lot cheaper!

Here is a website that explains shows how to make one:

Pretty sure she's figured it out by now as this was posted last summer.
