If you want to purchase a truly hypoallergenic pillow, memory foam is the way to go. Memory foam can fight allergens like dust mites and pollen. It’s also resistant to mold and bacterial growth as long as you keep it dry. What’s more, memory foam is not an animal product, so it won’t trigger those with animal allergies.
The onlye time memory foam might be more irritating to your allergies is when you have sensitivities to chemicals. Memory foam is synthetic, so it may increase your allergy symptoms if you’re bothered by chemical smells or artificial ingredients.
