If you have allergies, it is recommended to replace your pillows every 1-2 years. Over time, pillows can collect dust mites, mold, and other allergens, which can trigger allergy symptoms. Regularly replacing your pillows is an important part of maintaining a healthy sleeping environment and reducing your exposure to allergens. Additionally, it's important to wash your pillowcases regularly and to invest in allergen-proof covers for your pillows.
