Best pillow protectors
Your pillowcase gets washed weekly and your pillow almost never does, which is what a pillow protector is for.
I earn a commission if you buy through some links on this page. It never changes what I recommend, and I publish negative verdicts on brands I earn from. Editorial independence.
A pillowcase is washed with the sheets. A pillow is washed once or twice a year at best, and many pillows cannot be washed at all: foam and latex cannot go in a machine, and most down and feather pillows should not be washed hot.
Meanwhile the pillow is the item closest to your face for eight hours a night, and skin, sweat, oils and dust accumulate in the fill rather than in the case.
A pillow protector sits between the two: under the pillowcase, over the pillow. It washes with the bedding and keeps the fill clean, which extends the life of an expensive pillow and matters a great deal in an allergy household.
The specification that decides it is the same as for a mattress protector: whether it washes at 60 degrees, and whether it breathes.
The picks
The pick, if you want one answer
The Fine Bedding Company, 7.5 / 10. Washable at the temperature that actually kills dust mites, without insulating the pillow underneath.
| Product | Best for | From | Score |
|---|---|---|---|
| The Fine Bedding Company | Best washable pillow, which is the alternative | Budget | 7.5 / 10 |
| Ergoflex LIFE Protector | Best protector construction | Mid range | 7.8 / 10 |
| Aeyla Bamboo Pillowcase | Best top layer over it | Budget | 7.6 / 10 |
The Fine Bedding Company: Best washable pillow, which is the alternative
Budget · 7.5 / 10
Scores 7.5. The honest first question is whether you need a protector at all: a synthetic pillow that washes at 60 degrees solves the same problem directly. Foam and latex cannot be washed, which is precisely why they need protecting.
Buy it if
You would rather buy a pillow you can wash than protect one you cannot.
Do not buy it if
You own an expensive foam or latex pillow already.

Ergoflex LIFE Protector: Best protector construction
Mid range · 7.8 / 10
The highest scoring protector on this site at 7.8, and a mattress protector rather than a pillow one. The construction principle transfers exactly: a breathable membrane passes water vapour while blocking liquid, where a cheap plastic-backed layer stops air too.
Buy it if
You want a breathable membrane rather than a plastic-backed layer.
Do not buy it if
You only need a simple cotton barrier.

Aeyla Bamboo Pillowcase: Best top layer over it
Budget · 7.6 / 10
Scores 7.6. A protector is invisible in use, and the pillowcase over it is what you actually feel. A polyester case over a good pillow and a good protector undoes both.
Buy it if
You want the layer against your face to be something decent.
Do not buy it if
Your pillow is the wrong height, in which case fix that first.

Sixty degrees, and why forty is not enough
The one specification that matters
House dust mites survive a 40 degree wash. Forty removes accumulated allergen, which helps, and the population returns. Sixty kills them.
So in an allergy household, check the care label before the fabric. A protector that washes at 40 only is doing half the job.
The same rule applies to the pillowcase and the bedding over it. And note the conflict with nicer fibres: bamboo viscose and lyocell do not enjoy 60 degree washing, so cotton that tolerates a hot wash beats a smoother fibre you have to treat gently.
Which type you need
| Type | Buy it for |
|---|---|
| Cotton or poly-cotton protector | Everyday barrier against oils and sweat. The default. |
| Waterproof protector | Children, illness, incontinence. Check it breathes. |
| Fully zipped allergy encasement | Dust mite allergy. A tightly woven fabric or a stated pore size. |
For allergy specifically, look for a fully zipped encasement rather than a slip-on cover, and for a checkable specification: a tightly woven fabric or a stated pore size, rather than the word hypoallergenic, which is unregulated.
Do not insulate the pillow you paid for
This is the same mistake people make with mattress protectors, at a smaller scale that is closer to your face.
A cheap plastic-backed waterproof pillow protector blocks air as well as liquid. Put one over a micro-spring or latex pillow and you have cancelled the airflow that was the reason to buy it.
If you bought a pillow for temperature, buy a breathable membrane or a woven cotton protector rather than a laminated one. And remember that foam pillows are the warmest fill anyway, so a plastic layer on top compounds it.
And check the pillow is not simply finished
A protector extends a pillow's life. It does not restore one.
Fold the pillow in half and let go. If it springs back it still has structure. If it stays folded, it has lost it and no protector helps.
Rough lifespans: synthetic fill one to two years, foam two to three, down two to four, micro-spring three to four, latex four and up. Foam fails invisibly by compression set, losing height while looking identical.
Buy two protectors. They wash with the bedding, so one is always in the machine, and a protector that is never on the pillow is not protecting anything.
What not to buy
A protector that washes at 40 only, if anyone in the house has a dust mite allergy.
A cheap plastic-backed protector over a cooling pillow. You have insulated it.
A slip-on cover for allergy purposes. You want a fully zipped encasement.
One protector. Buy two, because they wash with the bedding.
A protector for a pillow that fails the fold test. Replace the pillow.
Also considered, and why they are not here
A roundup is only as useful as what it leaves out, so here is what was assessed and rejected for this list.
| Product | Why it is not on the list |
|---|---|
| Panda Bamboo Protector | A mattress protector, and worth noting the fibre point: bamboo viscose is pleasant and does not tolerate the 60 degree washing an allergy household needs. |
| Origin Extend Protector | Scores 7.6. A mattress protector where depth fit is the decisive specification, which has no equivalent on a pillow. |
| Simba Hybrid Pillow | The highest scoring pillow here at 7.9, and one that cannot be machine washed, which is exactly the case for protecting it. |
| Eve Microfibre | Scores 7.1. Washable synthetic fill, which reduces the need for a protector at the cost of holding height least well. |
How this list is made, and who made it
Independence
No brand pays to appear on this site and no placement is sold. Some links earn a commission if you buy, which never changes a score, an order or a verdict. Several of the lowest scores here are on products that carry commission, and several recommendations carry none.
Who writes this. Kyle Klinkradt has worked in the mattress and bedding industry for over ten years across retail, distribution and brand partnerships, and has handled, sold or assessed products from every major UK bed-in-a-box brand. Every review on this site is written by one person, so the scores mean the same thing from page to page.
What the assessment is. Construction specifications against what they physically do: spring height and where in the mattress it sits, spring count for the size, gauge, whether the base is sprung or foam, foam density where it is published, comfort layer depth and material. Then the commercial terms that decide what you are actually buying: trial against returns policy, guarantee length against the company's UK trading history at Companies House, and the regulatory record.
What it is not. This is not a laboratory. I do not publish pressure-mapping data or claim to have slept eight years on every mattress here, because nobody has and pages that imply otherwise are not telling you the truth. Where a judgement rests on construction rather than long-term use, the review says so.
What gets a product removed. Leaving the UK market, a specification change that makes the review inaccurate, or a corrected fact. Brands that have withdrawn are kept on the site with the score removed rather than quietly deleted, because people still search for them.

How these were chosen
Every product here has its own review on this site with a score out of 10, and the score is a judgement rather than an average. Nothing appears in a list because it pays more.
A score is against the market, not against its own range. The cheapest mattress in a lineup is usually priced to make the model above it look reasonable, and the flagship of a budget range has risen into a bracket where better brands compete. Both are judged against what else you could buy for the money.
Everything listed can actually be bought in the UK. That is not a given: Casper withdrew in July 2020 and Leesa no longer sells here, and both still appear in current British roundups with affiliate links attached.
I do not pad the list. Where only three or four products genuinely qualify, there are three or four. A list of seven when the category contains four good ones is a list with three bad recommendations in it.
Prices move constantly. Judge the cash price on the day rather than any percentage beside it. See every review on this site or where the real savings are.
Questions people ask
Do I need a pillow protector?
If your pillow cannot be machine washed, yes. Foam and latex cannot be washed and most down should not be washed hot, and the pillow is the item closest to your face for eight hours a night, with skin, sweat and dust accumulating in the fill.
What temperature should I wash a pillow protector at?
Sixty degrees if anyone in the house has a dust mite allergy, because mites survive a 40 degree wash. Forty removes accumulated allergen and the population returns.
Will a pillow protector make my pillow hot?
A cheap plastic-backed waterproof one will, because it blocks air as well as liquid. Over a micro-spring or latex pillow that cancels the airflow you bought it for. Use a breathable membrane or woven cotton instead.
What kind of pillow protector do I need for allergies?
A fully zipped encasement rather than a slip-on cover, with a checkable specification such as a tightly woven fabric or a stated pore size. Hypoallergenic is an unregulated word.
