6. Best hypoallergenic: National Allergy 10027 Duvet Cover

- Price: starting from around $38
- Material: cotton
- Pros: hypoallergenic, comes in a range of sizes, and individuals can use this as a duvet or cover

This cotton duvet protector features a patented tight weave that provides a barrier to allergens. An autolocking zipper with an extra fabric shield provides further protection from bed bugs.
According to this 2020 study, dust mite allergens usually go on particles of 10 microns (μm) — the manufacturers of this duvet protector state that this product has a gap of just 3.44 μm. This means the dust mite allergens will be too large to penetrate the duvet cover, meaning a person lying beneath it can sleep free of allergy symptoms.
Although its design allows for use as a protective layer between the duvet and a decorative cover, it can act as a cover alone. It comes in a range of sizes, but the only color option is white.
