You should wash most standard bed pillows about every 3–6 months, and wash pillowcases much more often (about once a week).

How Often to Wash Pillows (Quick Scoop)

Core Timeline

  • Pillowcases :
    • Wash every 1–2 weeks to keep oil, sweat, makeup, and bacteria off your skin.
  • Pillows (inner) :
    • General rule: 2–4 times per year (about every 3–6 months), depending on how much you sweat, if you have pets, or allergies.
  • If you have allergies, asthma, sweat a lot, or sleep with pets :
    • Aim for every 3 months for pillows.
  • Replacement, not just washing :
    • Many experts suggest replacing pillows about every 2 years (sooner—every 3–6 months—if you have lung or sinus issues).

Why Washing Pillows Matters Now

In the last few years, there’s been more awareness that pillows can harbor sweat, dust mites, dead skin, and bacteria, even if you use a clean pillowcase. Some coverage has gone mildly viral pointing out that unwashed bedding can build up more bacteria than everyday “dirty” surfaces, which pushed people to rethink how often they clean their beds.

That’s why newer guides from cleaning experts and health sites are converging around a more realistic but still hygienic routine: weekly pillowcase, seasonal pillow wash, and regular replacement.

Mini Guide by Pillow Type

Always check the care label first—different fillings need different care.

  • Feather/down pillows
    • Wash about every 6 months (or 3–4 times a year if you’re sensitive).
* Usually machine-washable (delicate or wool cycle), but they’re heavy when wet; dry completely so feathers don’t clump or smell.
  • Polyester / hollowfibre pillows
    • Often the easiest: machine-washable; can be cleaned 2–4 times per year.
* Gentle cycle, less detergent, then a good spin and tumble-dry.
  • Foam pillows (memory foam, solid foam)
    • Usually do not go in the washing machine.
* Spot-clean or sponge with warm soapy water about **once a year** ; air-dry away from direct heat or sun.
  • Special pillows (body pillows, decorative/throw pillows)
    • Clean about every 3–6 months , depending on how often you use or hug them.

Simple Routine You Can Follow

  1. Weekly
    • Wash pillowcases with your sheets.
  1. Every 1–2 months
    • If you use pillow protectors/liners, wash them.
 * Air pillows outside or near a window to freshen and reduce odors.
  1. Every 3–6 months
    • Wash the pillows themselves (follow label based on feather, polyester, or foam).
  1. Every 2 years (or sooner if you have breathing issues)
    • Replace pillows that stay flat, lumpy, or don’t bounce back when folded.
