how much are they when they are on sale? Is there any sort of pillow i should avoid due to chemicals and such? or can i just buy the cheapest polyester i see w/o being worried about things leeching into my water? (sorry, i've never bought filter floss before)I get the inexpensive poliester pillows from Walmart when they are on sale
the fiber filters well
thanks for the links! do you know if the ones from walmart/michaels will say on the packaging if chemicals were used?
