Typically, hotels wash their bedding once every week including various kinds of comforters, sheets, and pillows. However, they often swap out the pillowcases and linens between the guests. It's a common practice that the hotel comforters are rarely automatically changed ? unless a guest requests it.

In 2026, the hospitality industry standard for washing the actual pillows (the inner cushion) is generally every 3 to 6 months, or on an "as-needed" basis if they become visibly soiled. However, it is important to distinguish the pillow from the pillowcase and protector. Pillowcases are changed and laundered after every single guest stay as part of the standard room turnover. Most reputable 5-star and mid-range hotels also use a zippered pillow protector beneath the case, which acts as a barrier against moisture and dust mites; these are typically washed every few weeks or whenever a guest checks out. By 2026, many luxury chains have adopted "Hygiene Protocols" that include UV-C light sanitization for pillows between guests. If a pillow has permanent stains, a noticeable odor, or has lost its shape (usually after 18–24 months), the industry standard is to replace it entirely rather than attempting to deep-clean it again.
