Our Picks: Best Mattress Cover For Dust Mites reviews
1. HOSPITOLOGY PRODUCTS Sleep Defense System: Best for a Deeper Queen Mattress
This zippered encasement is designed for a queen mattress measuring 60 by 80 inches and 12 to 18 inches deep. Its wide depth range makes it a useful option if your mattress is thicker than the standard fit offered by some other covers in this roundup.
The cover has a waterproof barrier on all six sides and uses a polyester knit fabric with a waterproof membrane. It is machine washable and should be tumble dried on low. The product information also lists a five-year limited manufacturer’s warranty.
A full encasement can help keep dust mite allergens inside the mattress rather than allowing them to pass into your bedding. It does not remove dust mites from the mattress or replace other steps for managing allergies. Check your mattress depth carefully, since a cover that is too tight can be difficult to install and one that is too loose may not fit securely.
Compared with the other queen options here, this one stands out for its 12-to-18-inch depth range. That makes it a strong choice for a thicker mattress, though it may be more cover than you need for a shallower bed.
Pros:
- Fits queen mattresses from 12 to 18 inches deep
- Waterproof coverage on all six sides
- Machine washable and low-heat tumble dryable
- Listed with a five-year limited manufacturer’s warranty
Cons:
- Available size information here is for a queen mattress
- Does not eliminate dust mites already in the mattress
Verdict: Choose the HOSPITOLOGY encasement if you have a queen mattress deeper than 15 inches and want a washable, six-sided waterproof cover.
2. Guardmax Queen Mattress Protector: Best for a Secure, Standard-Depth Fit
Guardmax’s encasement is made for a queen mattress measuring 60 by 80 inches and 12 inches deep, with stretch to fit up to 13 inches. Its zipper runs around three sides and tucks under a stitched guard flap, a design intended to close the opening at the zipper pull.
The product combines a knitted polyester face with a waterproof layer underneath. The fabric is described as soft and quiet, and the cover is washable in a warm wash and can be tumble dried on low. The fabric is also listed as OEKO-TEX Standard 100 certified.
This cover is a practical match for a mattress within its stated depth range, especially if you want waterproof protection as well as an enclosed barrier. Its size range is narrower than the HOSPITOLOGY option and the Utopia Bedding 2-pack, so measure your mattress before ordering. It is not the best fit for a mattress deeper than 13 inches based on the supplied specifications.
Pros:
- Six-sided coverage with a guarded zipper closure
- Waterproof layer helps protect against spills and moisture
- Soft knitted face is described as quiet
- OEKO-TEX Standard 100 certified fabric
Cons:
- Fits queen mattresses only 12 to 13 inches deep
- Warm washing and low-heat drying are specified care requirements
Verdict: Consider Guardmax if your queen mattress is 12 or 13 inches deep and you want a zippered, waterproof encasement with a stated fabric certification.
3. Utopia Bedding Queen Mattress Protector, 2 Pack: Best for Two Covers
This zippered queen encasement is listed as a two-pack and fits a mattress measuring 60 by 80 inches and up to 15 inches deep. The stretchy fabric is designed to cover all sides and stay in place, while a wraparound zipper closes the encasement.
A waterproof layer helps block spills, sweat, and other everyday moisture from reaching the mattress. The knitted polyester fabric is described as smooth and non-crinkling, and the cover can be machine washed and tumble dried on low. Those features make it suitable for households that want both an allergen barrier and protection from messes.
The two-pack may be useful if you want a spare cover available while one is being washed, or if you need covers for two mattresses. Confirm the package contents and fit details on the product page before ordering. Unlike the HOSPITOLOGY option, this cover is not specified for mattresses deeper than 15 inches.
Pros:
- Listed as a two-pack
- Fits queen mattresses up to 15 inches deep
- Six-sided coverage with a waterproof barrier
- Machine washable and tumble dryable on low
Cons:
- Only the queen size is specified here
- Not listed for mattresses deeper than 15 inches
Verdict: This Utopia Bedding option is worth considering if you want two queen encasements and your mattress is no more than 15 inches deep.
4. SafeRest Premium Mattress Encasement: A Full-Size Option with Conflicting Depth Details
SafeRest’s option is a full-size zippered encasement with coverage on all sides. Its product details describe protection against spills, allergens, and bed bugs, along with a waterproof barrier and machine-washable care.
The supplied information describes the fabric as soft, breathable, and quiet. These qualities may matter if you are concerned that a waterproof layer could feel noisy or uncomfortable under your sheets. The encasement approach also covers the mattress sides, unlike a fitted protector that covers only the top and edges.
There is an important fit detail to check before buying: the product title specifies a fit for mattresses 9 to 12 inches high, while the description says it fits mattresses up to 15 inches thick. Because those depth details conflict, confirm the current size specifications with the seller before ordering. This is the only full-size option in this group, but the uncertainty makes it especially important to verify fit.
Pros:
- Full-size encasement with six-sided coverage
- Waterproof barrier for spills and moisture
- Machine washable
- Product details describe quiet, breathable fabric
Cons:
- Supplied depth specifications conflict
- Full size may not suit shoppers with a queen mattress
Verdict: SafeRest may suit a full-size bed, but verify the mattress-depth limit with the seller before purchasing.
5. Utopia Bedding Premium Six-Sided Encasement: Best for a 12-Inch Queen Mattress
This Utopia Bedding encasement is designed for a queen mattress measuring 60 by 80 inches with a 12-inch depth. A zippered closure surrounds the mattress, while the six-sided construction helps cover the top, bottom, and sides.
The knitted fabric is described as smooth, breathable, and quiet. The cover also has a waterproof barrier to help guard against spills and stains, and it can be machine washed. If your mattress is exactly 12 inches deep, the specified fit is straightforward; if it is thicker or thinner, check the listing for current fit guidance before ordering.
Compared with the Utopia Bedding two-pack above, this model is specified for a 12-inch mattress rather than up to 15 inches. That makes the depth fit less flexible, but its stated size may work well if your mattress matches it. As with any encasement, a snug closure can help keep the mattress enclosed, but it is not a treatment for dust mites or allergy symptoms.
Pros:
- Designed for a 12-inch queen mattress
- Six-sided zippered coverage
- Waterproof protection against spills and stains
- Soft, breathable knitted fabric described as quiet
Cons:
- Depth is specified as 12 inches, with no wider range provided
- Only queen size is described in the supplied details
Verdict: Pick this Utopia Bedding encasement if you have a 12-inch queen mattress and want a washable, waterproof cover with full coverage.
How to Choose a Mattress Cover for Dust Mites
Look for a Full Encasement, Not Just a Top Protector
A fitted mattress protector usually covers the sleeping surface and wraps around the edges, while a mattress encasement surrounds the mattress on all sides and closes with a zipper. For limiting contact with dust mite allergens held in the mattress, look for a design that fully encloses it and has a closure that stays shut. A cover alone does not remove mites or allergens already present.
Measure the Mattress Width, Length, and Depth
Check the mattress size and measure its depth from the bottom to the top, including any permanent padding. Compare those measurements with the product’s stated fit range. A cover that is too small may be difficult to close, while a loose fit may not stay in place. Pay special attention to depth: the options here range from a specific 12-inch fit to queen covers that stretch to 18 inches.
Consider Whether You Need Waterproof Protection
Waterproof layers can help protect against spills, sweat, and accidents, which may be useful for children, pets, or everyday messes. The products in this list offer waterproof protection, but their materials and construction differ. If you do not need spill protection, consider whether the added layer and its care instructions fit your priorities.
Check Fabric Feel and Noise Details
A cover sits directly on the mattress, beneath your sheets, so fabric comfort matters. Several options describe their knitted fabric as soft or quiet, and one describes a cotton fabric. These descriptions can help you compare the designs, but feel is personal. If you are sensitive to texture or noise, check the product details and return terms before buying.
Read the Washing and Drying Instructions
Dust mite allergen management may involve regular cleaning of bedding, so choose a cover you can care for as directed. The products listed here are machine washable, but washing temperatures and drying instructions vary. Follow the specific care label; high heat may not be suitable for every waterproof membrane.
Check the Closure and Any Certification Claims
The zipper is a key part of an encasement because it closes the opening around the mattress. Look for clear product details about how the zipper closes and whether a flap covers it. Guardmax also lists OEKO-TEX Standard 100 certification for its fabric. Certification details apply to the material claim provided and should not be confused with a guarantee that the cover treats allergies.
Frequently Asked Questions
Can a mattress encasement help with dust mite allergies?
A fully enclosed cover can act as a barrier between you and allergens in the mattress. It may be one part of an allergy-management plan, but it does not kill dust mites or remove allergens already inside the mattress. Ask a health professional for advice about ongoing symptoms.
Is a zippered encasement better than a fitted mattress protector for dust mites?
An encasement surrounds the mattress and closes with a zipper, while a fitted protector may leave parts of the mattress uncovered. If you want to enclose the mattress, choose a full encasement with a fit and closure suited to your bed.
Do these mattress covers kill dust mites?
The supplied product details describe covers intended to create a barrier or provide dust mite protection. They do not establish that the covers kill mites. Cleaning and care should follow the product instructions.
Should I choose a waterproof cover?
A waterproof layer can help keep spills and other moisture from reaching the mattress. It is useful if you want that added protection, but compare the fabric and care instructions as well as the fit.
How do I know what depth to buy?
Measure your mattress from its bottom edge to the top surface, then compare that number with the cover’s stated depth range. Include any permanent pillow top or built-in padding in the measurement. For the SafeRest option in this list, confirm the depth range because the supplied product details do not match.
Can I wash a mattress encasement?
All five options are described as machine washable. Follow the instructions for the specific cover, including any limits on water temperature and dryer heat. Several products specify low-heat tumble drying.
Final Recommendation
For most shoppers choosing among these options, the HOSPITOLOGY PRODUCTS Sleep Defense System is the most flexible pick for a queen mattress because its stated depth range covers mattresses from 12 to 18 inches. If your mattress is 12 to 13 inches deep, Guardmax offers a narrower fit and lists OEKO-TEX Standard 100 certified fabric. Choose the Utopia Bedding two-pack if you want two covers and your mattress is no deeper than 15 inches. Whichever you choose, measure first and treat the encasement as a barrier—not a substitute for cleaning or medical guidance.
