Well the down became a non issue... I was totally allergic to it.
I did contact Pacific Coast another very popular down company... they gave me some info some of you might find interesting on their Hypoallergenic treatment called Hyperclean:
Thank you for contacting Pacific Coast Feather Company.
We have devised a washing process where detergents and hot water temperatures are used very efficiently at the start of our wash cycles to clean and sterilize the down without damaging the fine filaments. To back up our Allergy-Free guarantee, we thoroughly tested our washing process to find the correct number of rinse cycles to bring pH to 7.0
(neutral) before we dry the down. We do not use perfume agents in any of our washing processes, preferring to make sure the down is simply fully cleaned and naturally fresh-smelling.
Some details of our washing processes are trade secrets and cannot be disclosed for competitive reasons, and unfortunately this includes the exact chemicals used in our detergents. Some companies in our industry used to use formaldehyde, but we never used that, being aware that this chemical has caused some sensitive individuals some trouble even in very low concentrations. We admit that we use one sterilizing chemical in our detergent wash bath approved by the USDA as virucidal, which also kills fungus and molds. This chemical is toxic to humans in high enough concentrations. However, even in our sterilizing wash bath it is never present in concentrations higher than those sold in household cleaning solutions at your local grocery store. Furthermore, it is completely water-soluble, and we are sure that our rinsing process is thorough enough to remove all but the scantest trace of this chemical by the last rinse cycle, as our pH data over many years of production lots support this conclusion.
If we were not sure, we would not offer our guarantee.
I hope this helps you!
If you have any further questions, please let me know.
I might consider the polyester treated with silicone - or I might try to find an organic cotton comforter that will cost me an arm and a leg
Or I might just try to find some nice cotton blankets and quilts and forgo the duvet type look that I like so much. We will see... I have a hard time not having allergies at night so I am trying to come up with the healthiest possible bed. I thought down woudl be nice because is not synthetic but I didnt think about being allergic to down or its dust. DUH
