Frequently asked questions

What should I look for in a bed bug mattress protector?

Look for a zippered encasement that fully seals the mattress, with a bug-proof zipper and reinforced seams. Certifications like OEKO-TEX or CertiPUR-US indicate material safety. Also consider breathability and waterproofing if needed.

Are bed bug protectors also effective against dust mites?

Yes, most bed bug protectors also block dust mites due to the tight weave and full encasement design. Some are specifically certified as asthma & allergy friendly for additional assurance.

Can I use a regular mattress pad on top of a bed bug protector?

Yes, you can place a mattress pad or topper over the encasement, but ensure the encasement remains sealed. Some protectors are designed to be breathable enough to layer comfortably.

How often should I wash a bed bug mattress protector?

Do these protectors make the mattress feel hot?
