How Often Should Hotel Duvets and Pillows Actually Be Laundered?

The bit of the bed nobody checks until a guest complains about it.

Sheets get changed every stay, sometimes every day. Duvets and pillows are a different story — most housekeeping teams give them a shake, check for stains, and put them back. That gap is where mould, dust mite allergens and odour build up without anyone noticing until a guest leaves a review about it. Here’s what the schedule should actually look like, and why “whenever it looks dirty” isn’t good enough.

The short answer: quarterly, minimum

Most hotels should be laundering duvets and pillows at least every three months, with protectors or covers inspected and changed between stays. That’s the baseline for a clean room with no spills, no illness and no visible staining. It isn’t a figure set by regulation — there’s no HTM or FSA standard covering duvets the way there is for NHS linen or kitchen cloths — but it’s the interval most hotel laundry contracts settle on once you factor in occupancy and guest turnover.

High-occupancy properties — city centre hotels running above 80% occupancy, or budget chains with fast turnover — should be closer to monthly. A duvet that’s slept under 25 times a month wears differently to one slept under eight times.

What actually drives the interval up or down

Three things change the schedule from the baseline:

Occupancy rate. More guests per duvet means more skin oils, sweat and allergen build-up per month, regardless of how clean a stay looks on the surface.

Whether a protector is used. A properly fitted, laundered-between-stays protector does most of the work. Without one, the duvet itself takes the hit every single night, and the three-month interval should shrink.

Guest profile. Pet-friendly rooms, long-stay guests and anyone travelling with children need pillows and duvets checked and washed more often — pet dander and childhood illness both shorten the safe interval considerably.

Signs a duvet should have gone to the laundry already

Don’t wait for the calendar if any of these show up on inspection:

Yellowing at the edges or in patches — usually sweat or body oil working through the protector and into the filling. Once it’s visible, it’s already been happening for a while.

A musty smell when the duvet is lifted or shaken — a sign of moisture trapped in the filling, often from a room with poor ventilation or a guest drying towels on the bed.

Flattened or lumped filling — not a hygiene issue on its own, but it means the duvet has been compressed and is holding less air, which usually means it’s also holding more trapped moisture and skin cells than it should.

Any visible stain — blood, makeup, fake tan, wine. These need immediate laundering, not a wait for the next scheduled wash. A stain left to set for weeks is far harder to shift and may need specialist treatment.

Pillows need a shorter interval than duvets

Pillows sit closer to the face, absorb more saliva, sweat and hair product, and generally need washing more frequently than duvets — every six to eight weeks is a reasonable target where protectors are used, with full replacement cycled in annually regardless of how clean they look. Filling breaks down with washing faster in pillows than duvets because the fill-to-fabric ratio is tighter and the wash temperature needed to deal with dust mites is higher.

If a hotel is running synthetic fill rather than down or feather, the washing interval can usually stretch slightly, since synthetic fill dries faster and holds up better to repeated commercial laundering. Down and feather pillows need more careful drying — rushed drying leaves damp pockets inside the fill, which is exactly the mould risk you’re trying to avoid.

Why this is one to outsource rather than batch in-house

Duvets and pillows are bulky, slow to dry properly, and easy to under-dry if you’re running a standard in-house machine built for sheets and towels. Under-dried filling is where the mould and odour problems start — not from infrequent washing, but from washing that doesn’t finish the job. A commercial laundry running proper drying cycles and rotation stock means a property never has to take rooms out of service while a duvet dries, because a laundered replacement is already on its way back.

This is also where having a documented schedule matters for insurance and inspection purposes. If a guest raises an allergy complaint or an environmental health visit asks about bedding hygiene, “we launder duvets quarterly and pillows every six to eight weeks, with protectors changed between every stay” is a defensible answer. “We wash them when they look like they need it” is not.

Building it into your par stock

A quarterly duvet wash means every duvet in the property needs a laundered double somewhere in rotation — you can’t take a room’s duvet out of service for 24 hours without a replacement on the shelf. The same logic that applies to sheet and towel par levels applies here: work out your total duvet count, divide by how many you’re comfortable having out of circulation at once, and that’s your minimum spare stock. Restaurants and kitchens run the same calculation for restaurant linen — it’s the same principle, just applied to a bulkier item with a longer wash cycle.

Get this wrong and you end up either over-buying duvets that sit in storage most of the year, or scrambling every time a batch goes out for its quarterly wash. Neither is a good use of a housekeeping budget.
