CARE INSTRUCTIONS Our aquaplush® hypoallergenic polyester pillow and fairfax hypoallergenic polyester pillow can be machine washed in cold or warm water. Wash in cold or warm water on a gentle cycle with a mild detergent in a washing machine large enough to allow movement in the drum. Do not use bleach or fabric softener. Tumble dry on low in a front load dryer until thoroughly dried to kill dust mites and to prevent mold growth. They should be laundered if there are visible stains or noticeable odors. Pillows should be laundered at least every 6 months. The pillows on which you sleep at luxury hotels have been in service and may feel different than those fresh out of the package. Your new pillow may appear flat when it arrives as it has been compressed for shipping.
