If you wake up congested every morning, the problem is usually not your mattress itself — it is what lives inside it. Dust mites and dander settle deep in the padding and stay there. A proper allergen proof cover for mattresses and pillows seals that surface so you are not breathing the contents of your bed all night. The list below covers seven real options, from a zippered encasement that closes a mattress off on all sides to a plush fitted protector that goes on like a sheet.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Some covers encase the whole mattress with a zipper, while others simply stretch over the top like a fitted sheet. Knowing which one suits your bed and your routine is the difference between a cover that helps and one that ends up in the closet.
You will see exactly which covers seal on all six sides, which ones breathe well enough for hot sleepers, and how each one handles washing. Below is a working shortlist of allergen proof covers for mattresses and pillows.
Top Picks
How To Choose The Best Allergen Proof Covers for Mattresses and Pillows
Your first decision is full encasement or fitted protector. A full encasement seals the mattress on all six sides with a zipper, so dust mites cannot get in from the bottom or the edges. A fitted protector stretches over the top and partway down the sides; it is faster to change, but the underside of the mattress stays exposed. If dust mite allergy is your main concern, the encasement is the stronger choice, because mites live throughout the mattress, not just on top.
Encasement versus fitted protector
A zippered encasement takes more effort to install because you lift the mattress or slide the cover around it. Some designs, like the CleanRest zip-off top, let you remove just the quilted top layer for washing without pulling the whole thing off. A fitted protector goes on like a sheet and comes off in seconds. The trade-off is coverage: the fitted style guards the sleep surface, while the encasement guards the whole mattress. Decide which matters more for your situation before you start comparing fabrics.
Fabric weave and breathability
Dust mites are tiny, so the weave of the fabric is what stops them. A tightly woven microfiber or a membrane-backed fabric creates a barrier that mites and their waste cannot pass through. The best covers balance that tight weave with breathability so you do not wake up sweaty. Tencel and moisture-wicking fabrics pull heat and moisture away from your body, which helps if you sleep hot. Look for a cover described as breathable and noiseless if you want to keep the feel of your mattress.
Depth and fit
Measure your mattress depth before you buy anything. A cover rated for 9 inches will not stretch over an 18-inch pillow-top, and a cover rated for 18 inches will bunch up on a thin mattress. Many fitted protectors use elastic all the way around the edge, which keeps them from sliding. Encasements rely on a zipper and a snug fit, so the depth rating has to match your mattress closely. If your bed is on an adjustable base, check that the cover is listed as compatible with one.
Washing and durability
Allergen covers need regular washing to stay effective, so check the care instructions before you commit. Most are machine washable, but the waterproof backing can break down if you use high heat. A cold or gentle cycle with low tumble drying is the safest routine. Zippers are the part that fails first on encasements, so pay attention to how the zipper is built and whether there is a flap covering it. A warranty that runs several years is a good sign the maker expects the seams and zipper to hold up.

Detailed Reviews
1. Dust Mite and Allergen Proof Mattress Encasing
Our pick — 4.5+★ from 300+ verified ratings; the strongest balance of quality and price.
A full zippered seal in a silky microfiber that does not crinkle or sleep hot.
This is the cover that closes your mattress off completely. The zipper runs the full length of the encasement, and there is an interior flap behind it so nothing slips through the gap. That matters because dust mites live on the underside and along the edges too, not just the top surface. A fitted protector leaves those areas exposed; a zippered encasement does not.
The brand behind it is Mission: Allergy, and the encasing is described as designed by a board-certified allergist and third-party tested by Indoor Biotechnologies. The maker lists it as blocking 100% of dust mite and animal dander allergens and as certified bedbug-proof. The tightly woven 100% microfiber polyester is air- and water vapor-permeable, so moisture vapor escapes while liquid stays out. In practice that means the cover feels soft and silky rather than plasticky, and it does not trap heat the way a vinyl-backed pad does.
Buyers report that this cover is easy to get on alone, even on a queen mattress, and that it stays put without slipping. The one clear trade-off is cost — it sits at the higher end of the mid-range, and the review pages are split on whether that is justified. What holds up is the long-term picture: people who have used it for years describe the sleep surface staying soft and the cover showing no signs of wear. As owners put it, “I’ve had allergies all my life and these products changed my sleeping pattern to the positive.”
What the encasement delivers
- Zipper closure with an interior flap seals the full mattress, not just the top.
- Microfiber polyester is air- and water vapor-permeable, so it breathes without letting liquid through.
- Backed by a lifetime warranty from the maker.
- Easy for one person to install on a queen bed, and it does not slide.
What to expect going in
- Pricier than a basic fitted pad, and reviews are mixed on whether the cost is fair.
- Some static can build up straight out of the dryer, though it settles under a top sheet.
- The 12-inch depth rating will not stretch over very thick pillow-top mattresses.
Reach for this if: you want a full six-sided seal against dust mites and dander and you have a mattress around 12 inches deep.
Look elsewhere if: your bed is a deep pillow-top over 12 inches, since this encasement is rated for 12 inches and a deeper-pocket cover will fit better.
2. Mission: Allergy Barrier II Mattress Cover, Queen
The thinner-mattress specialist from the same allergy-focused maker, with a 9-inch depth rating.
If your bed is a slim mattress or a box spring, this is the version that fits. It is rated for a 9-inch depth, and the outer dimensions are 60 x 80 x 9 inches. Compared with the King Size Premium Tencel cover above, which is rated to 18 inches, this one is purpose-built for a thinner build. Put those two depth ratings side by side and the difference is the whole point: this is the pick for a mattress that does not have a lot of height to grab onto.
The construction mirrors the best-overall pick — bound seams, an interior zipper flap, and an extra-long zipper for easy placement — but the warranty is ten years rather than lifetime. The fabric is the same tightly woven 100% microfiber polyester, described as air- and water vapor-permeable while staying water repellant. It is also listed as third-party tested and certified bedbug-proof. A bunkie-board cover in the four-inch style has been used successfully on a 7-inch IKEA Morgedal twin mattress, where the fit was described as not perfect but not too loose either.
Owners mention the allergy relief wins them over here, followed closely by how simple it is to install. Softness earns its own steady praise, and reviewers describe the cover as silky rather than crinkly. The honest caveats are predictable: value is a split verdict, and the zipper draws some mixed feedback. One detail worth knowing before you buy — the manufacturer calls it “imperceptible beneath the sheets,” and that is a stretch; some buyers still notice it and hear a slight plastic sound when moving around on the bed, though the cover itself is well made.
Where it earns its keep: For anyone managing dust mite allergy on a thin mattress or box spring, this cover delivers effective relief in a soft microfiber build that installs without a fight and holds up over time.
Fit note worth hearing: The 9-inch depth rating is the real constraint. If your mattress is thicker than that, size up to a deeper cover rather than forcing this one on.
The right buyer: a thin mattress or box spring owner managing dust mite allergy who wants a proper zippered seal.
Not the one for: a pillow-top or foam mattress that runs past 9 inches deep, where the fit will be too tight.
3. King Size Premium Mattress Protector
A plush Tencel-topped protector that stays quiet and does not trap your body heat.
Hot sleepers tend to hate mattress protectors because most of them feel like a plastic bag. This one goes the other way. The top layer is Tencel, a fiber made from wood pulp that is listed as breathable and cooling, and the build is a triple-layer design with the Tencel top, a waterproof barrier underneath, and an 18-inch deep pocket. The fabric blend is 69% polyester and 31% Lyocell, and the cover is OEKO-TEX 100 certified. OEKO-TEX 100 means the fabric is tested free of over 100 harmful chemicals, which matters against bare skin all night.
Fit is the other strong suit. The closure is a 360-degree elastic fitted-sheet style, so it pulls on like a sheet over mattresses up to 18 inches deep. People report it sliding over a 14-inch Beautyrest without slipping, and one described stretching it over a thick Tempur-Pedic without any bunching. The depth rating is the same 18 inches as the Bedgear below, so both will handle a deep bed — the difference is the Tencel top here versus the Dri-Tec fabric there.
Buyers keep coming back to quality and fit, along with cooling and value. The one honest split is water resistance — some customers note it is fully waterproof and others say it is not, so treat that claim with a little caution and do not rely on it for a major spill. The noiseless claim, though, holds up well: people describe it as moving with you without any chip-bag crinkle. It is also machine washable and dryer safe, which keeps the maintenance simple.
The cooling case: A breathable Tencel top over a triple-layer waterproof barrier means you get spill protection without the sweaty plastic feel that sends most protectors back to the store.
The water-resistance caveat: Feedback on waterproofing is genuinely divided, so this is a better pick for allergen and dust-mite protection than for guarding against a full glass of juice.
Best suited to: hot sleepers on a deep mattress who want allergen and dust-mite protection with a cool, quiet surface.
Think twice if: heavy liquid protection is your main reason for buying, since the waterproof rating draws mixed reports.
4. CleanRest PRO Presto! Quilted Zip-Off Top Mattress Encasement
The encasement with a top that unzips and comes off in 45 seconds for washing.
Most encasements make you strip the whole bed and haul the mattress around every time you want to wash them. This one solves that with a quilted top that zips off and goes straight into the machine. CleanRest rates the top removal at 45 seconds for one person, with no mattress lifting. The MicronOne fabric is described as blocking bed bugs, dust mites, and allergens without harsh chemicals, and the zipper is a patented Zip-N-Click 2X locking design that closes 360 degrees around the mattress. For bed bug protection specifically, that full closure with a locking zipper is what you want.
The listed fit is 38 x 75 inches for a twin, for mattresses 7 to 15 inches deep, and the encasement is backed by a 10-year warranty. A quilted top also gives you a bit of padding under the sheet, which some people prefer over a thin membrane. Reviews on comfort are mixed, with some finding it soft and luxurious and others noting it feels more functional than plush. The install experience varies by bed size — a queen on a 12-inch mattress is reported to fit perfectly, while a larger size on a thick memory foam bed can take two people and some effort.
This is the pick for someone who wants hotel-grade hygiene and plans to wash the cover often. The quality is the standout, and the removable top makes the laundry rotation genuinely practical. The trade-off is the install: the two-piece zippered design can be a wrestling match on a big foam mattress, and the stretch fabric can compress a very soft bed more than you would like. Size the depth carefully and go in expecting a firm fit.
Why it stands out
- The quilted top unzips and comes off in 45 seconds for washing.
- Zip-N-Click 2X locking zipper closes 360 degrees for full bed bug protection.
- MicronOne fabric blocks dust mites and allergens without harsh chemicals.
- 10-year warranty and a machine-washable, high-heat-washable build.
Worth knowing first
- Installation on a large thick foam mattress can take two people.
- Comfort feedback is mixed — some find it plush, others more functional.
- Stretch fabric can compress a soft mattress tighter than you expect.
Ideal for: anyone who wants to wash the cover weekly without stripping the bed, and bed bug protection is a priority.
Skip if: you have a very soft memory foam mattress and want to keep its exact feel, since a firm-fitting stretch encasement will change it.
5. MALOUF Sleep TITE Hypoallergenic 100% Waterproof Protector
A fitted protector built for extra-deep beds, all the way up to 22 inches.
The depth range is the headline here. This cover fits mattresses from 6 to 22 inches, which covers everything from a slim foam bed to a towering pillow-top with a topper stacked on it. That is the widest span on this list. The other fitted options here top out at 18 inches, so if you have an unusually deep mattress, this is the one that is actually built to reach around it.
The build is a five-sided design that protects the top and sides of the mattress, with a moisture-wicking Tencel fabric, a temperature-regulating Omniphase material, and the Sleep Tite H2Pro membrane for waterproofing. Malouf lists it as repelling perspiration and urine, and backs it with a 15-year warranty. The material is described as ultra-thin and breathable, quiet, and unlikely to change the feel of your mattress. A cotton top gives it a soft surface rather than a slick synthetic one.
Quality is the thing that stands out most in the feedback, and complete mattress protection comes next. Comfort also earns steady praise. The cooling effect is the genuinely split point: some say it keeps the bed cool, and others find it traps body heat by morning. Fit is also mixed — the large side band fits extra-deep mattresses snugly, but a few find it slimmer than expected. If cooling is your top priority, the Bedgear below leans harder into that; if you need the deepest possible fit, this one leads on depth.
What you are paying for: a 6-to-22-inch depth range, a five-sided waterproof build, and a 15-year warranty make this the most accommodating fitted protector here for an extra-deep bed.
What to plan around: the cooling claim is divisive, so if you overheat easily, look at a cover with a stronger cooling reputation rather than counting on this one to run cool every night.
The fit for: a deep or extra-deep mattress where a standard 18-inch cover cannot reach around the sides.
Consider another pick if: you sleep hot and want cooling to be the main feature, since feedback on heat here splits both ways.
6. 23 Threads Plush Waterproof Zippered Mattress Encasement
A plush-topped encasement that closes on all six sides and goes on without lifting the mattress.
This is the pick for anyone who wants the feel of a padded cover but still wants the full six-sided coverage of a zippered encasement. The top is a plush quilted surface, and the barrier underneath is a bio-based TPU layer that keeps spills and sweat out. It fits mattresses up to 15 inches deep, and the butterfly-style design is patent-pending and lets you put it on and take it off without fully lifting the mattress. It uses GRS and Oeko-Tex 100 certified materials plus the maker’s Ctrl+Z technology, described as helping the polyester break down as fast as natural fibers to cut plastic waste.
Reviews here are the most divided of the group. Some buyers find it easy to install solo and say the soft top padding adds comfort, with no crinkly noise. Others feel it is not worth the price and find it light on firmness. That split likely depends on what you expect — a plush encasement is not a mattress topper, and it will not add support to a bed that lacks it. If you go in wanting allergen and dust-mite protection with a softer top surface, the feedback lines up well.
The brand supplies hotels, and that shows in the overall construction quality. The catch worth naming is price and padding expectation: a plush encasement adds a soft layer, not firmness, so do not buy it to fix a sagging mattress. And because it zips on all six sides, the 15-inch depth rating is firm — measure before you order.
The six-sided case: You get complete coverage on all six sides, a plush quilted top for a softer surface, and a TPU underlayer (a thin waterproof film) that keeps liquids out. Together they make a strong allergen and dust-mite shield with more padding than a bare membrane.
The expectation to set: Do not read the plush top as added support — it is a soft surface layer, and some buyers expecting firmness have been disappointed.
Worth it for: a bed up to 15 inches deep where you want six-sided protection with a softer, padded top.
Probably not for: anyone hoping the plush layer will firm up a soft mattress or add support.
7. Bedgear Dri-Tec Waterproof Mattress Protector, King
The moisture-wicking protector for anyone who wakes up hot and sticky.
Dri-Tec is the fabric here, and the job it does is pull moisture away from your body and spread it out so it evaporates faster. If you sweat at night or sleep with a partner who does, that is the whole reason to choose this over a plain encasement. It is waterproof and breathable, fits mattresses up to 18 inches deep with a fully banded elastic edge, and is machine washable on cold with low tumble drying. It is also listed as hypoallergenic and adjustable-base friendly.
The real-world track record on this one is strong. Allergy and asthma sufferers who need airflow and temperature control keep coming back to it, and a longtime user reports running it on multiple mattresses over about eight years. In that account a wine spill soaked through the sheets and left no stain on the mattress, and a urine incident did not penetrate either. That is the kind of spill protection the fitted Tencel and MALOUF covers are less sure of. The depth rating matches the Tencel cover at 18 inches, but the fabric is the difference — Dri-Tec is built around wicking, while Tencel is built around cooling at the surface.
Feedback is very positive on fit, staying put, washability, and softness, including one buyer noting it does not change the feel of the bed. The one thing to watch is that this is a premium fitted protector, and the value is not universal — some find it cheaper elsewhere. If you have a demanding allergy situation and you want a cover that breathes and stays in place, this is one of the few that does both well.
The case for Dri-Tec
- Dri-Tec fabric pulls moisture away from the body and speeds evaporation.
- Waterproof barrier holds up in real spills, including wine and pet accidents.
- Fully banded elastic fits mattresses up to 18 inches deep and stays put.
- Hypoallergenic and adjustable-base friendly, machine washable cold.
The realistic downsides
- Premium fitted style, so the value is not automatic at every retailer.
- It is a fitted protector, not a zippered encasement, so the underside of the mattress is not covered.
Reach for this if: night sweats, allergies, or pets make you want a breathable, moisture-wicking cover that stays put on a deep mattress.
Look elsewhere if: you need full six-sided encasement for the underside of the mattress, which a fitted protector cannot give you.
Know the Specs
Pore size and fabric weave
Dust mites are microscopic, so the weave is what decides whether an allergen proof cover actually works. A tightly woven microfiber or a membrane-backed fabric creates a barrier that mites and their waste cannot cross. A loose knit does not. The covers here use tightly woven microfiber polyester, Tencel blends, or a membrane layer to close that gap, and most are labeled with a specific allergen-blocking claim. That label is the spec to check first, since a soft comfortable cover that lets mites through is not doing its job.
Encasement versus fitted protector
A zippered encasement covers all six sides and closes with a zipper plus an interior flap, so nothing slips in through the seams. A fitted protector stretches over the top and sides but leaves the bottom open. The encasement offers more complete coverage but takes longer to install, while the fitted protector installs in seconds and is easier to wash. If a dust mite allergy is your main reason for buying, lean toward the encasement. If you want spill protection and easy laundry, the fitted style is more practical.
Depth rating and fit
The depth rating is the number to measure against your mattress before you buy. A 9-inch cover will not stretch over an 18-inch pillow-top, and an 18-inch cover will bunch up on a thin mattress. Fitted protectors rely on fully banded elastic or 360-degree elastic to stay put, while encasements rely on a snug zippered fit. If your bed is on an adjustable base, confirm the cover is listed as compatible. The deepest option here reaches 22 inches, which covers tall pillow-tops and thick foam beds that standard covers cannot grab.
Breathability and cooling
A cover that traps heat is one you will stop using. Breathable fabrics like Tencel and moisture-wicking performance materials pull heat and sweat away rather than sealing them against your skin. A membrane-backed cover can still breathe if the manufacturer designs it to pass water vapor while blocking liquid. The trade-off is that a fully waterproof barrier can run warmer than a porous fabric, which is why cooling features matter for hot sleepers. Look for covers described as breathable and noiseless if you want to keep the feel of your mattress intact.

The Bottom Line
For most people, the allergen proof covers for mattresses and pillows winner is the Dust Mite and Allergen Proof Mattress Encasing. It seals all six sides with a zipper and interior flap, breathes through a tightly woven microfiber, and carries a lifetime warranty. If you sleep hot and want a cool, quiet surface, grab the King Size Premium Tencel Cover. For a deep or extra-deep mattress that needs a fitted protector with room to stretch, the MALOUF Sleep TITE reaches from 6 to 22 inches. And if easy washing is your priority, the CleanRest zip-off top lets you pull just the top layer off in 45 seconds. Do not buy a cover that is rated shallower than your mattress — measure the depth first, and the rest of the choice falls into place.
