Foam pillows made from latex are more hypoallergenic than pillows made with natural fillers such as down or feathers and synthetic fillers such as polyester. But a worn-out foam pillow may cause allergy problems.
Foam is Hypoallergenic
The process of manufacturing foam for pillows is sterile. Most bed pillows undergo lengthy washing procedures before they are sold.
Pillows are Pre-Treated
Good-quality foam bed pillows are sold with certification of anti-mildew treatment, anti-microbial treatment and dust mite resistance. They will be labelled as hypoallergenic.
Avoid Mold and Mildew
Both mould and mildew are potentially dangerous allergens that may develop in foam pillows when they are either damp or overused. A worn or damp foam pillow will lose its ability to ventilate itself.
A foam bed pillow should be covered with the manufacturer's fitted protector, which is designed to filter out dust mites and microbes. Keeping the pillow dry maintains its protection.
Pillows May be Laundered
Most foam bed pillows can be occasionally washed after they are used, carefully following manufacturer's directions. They should be dried in open air and not in a dryer.
