I invested in some higher-end pillows, and started to notice how dirty they were getting (and I'm also sensitive to allergies). I didn't realize pillow protectors were even a thing, until AllerEase! This protector is keeping my pillows clean and allergy-free, which is a tough feat in the Texas hill country! I also was worried that the pillow cover would make my pillows less comfortable, but that is not the case :)
