Hi dafunda. It is my understanding and experience that if a company that produces down products cleans the down sufficiently that there will be no smell. Dirt and allergens still clinging to the feathers can cause a funky "birdy" smell and can also cause allergenic reactions.
I've actually had to return expensive down pillows that I bought by mail before because of the same weird smell. The retailer advised me to let them sit outside in the sun to air out or to put them in the dryer with a dryer cloth to counteract the smell. However, for the big $$ I spent for them....I thought that was silly...so they went back for a refund.
I ended up buying some down pillows at a local bedding store. I told the clerk the problem I had had with other down pillows and she opened one to let me smell it....and there was no smell...exept that wonderful new smell. Ha!
So, I think a lot of it has to do with the manufacturer and how well they clean the feathers to begin with. I wouldn't want pillows that smelled funky either. Good luck!
