|-
| Bandana || Better than nothing. Decreases droplets spray from more than 8 feet to about 4 feet. An adequate piece of cloth can be repurposed. Washable, reusable. || "Only reduces the droplets by about 50 per cent and neck fleeces increase the amount of spray, probably by dispersing the largest droplets into many smaller droplets."<ref name="economictimes.indiatimes.com">{{cite web |title=Why wearing a bandana face-mask is a very bad idea |url=https://economictimes.indiatimes.com/industry/healthcare/biotech/healthcare/why-wearing-a-bandana-face-mask-is-a-very-bad-idea/cotton-alternatives/slideshow/77741019.cms |website=economictimes.indiatimes.com |access-date=28 November 2020}}</ref>

| Homemade cloth mask || Better than bandanas. Hand-made cotton face coverings eliminate 70 to 90 per cent of the spray, depending on the layers and the pleating.<ref name="economictimes.indiatimes.com"/> Washable, reusable. ||

| T-shirt mask || They’re comfortable. Effectiveness can be increased by using more than one layer of material.<ref name="healthgrades.com"/> Washable, reusable. || They are one-third as effective as disposable surgical masks.<ref name="healthgrades.com">{{cite web |title=9 Types of Masks and How Effective They Are |url=https://www.healthgrades.com/right-care/coronavirus/9-types-of-masks-and-how-effective-they-are |website=healthgrades.com |access-date=28 November 2020}}</ref>
|-
| Store-bought cloth mask || High quality masks could be 80-95 percent protective.<ref name="healthgrades.com"/> Washable, reusable. || Low-quality masks made of very thin materials could still be 10-20 percent protective.<ref name="healthgrades.com"/>
|-
| Cloth masks with filter || "Adding a polypropylene filter to a two-layer cloth mask can increase filtration efficiency from 35% to nearly 70%."<ref name="healthgrades.com"/> Washable, reusable. ||
|-
| Neck gaiters and balaclavas || Washable, reusable. || Synthetic fabric, which is often used, isn't as effective as cotton in preventing the spread of small particles. Moreover, neck gaiters made of synthetic fleece can be harmful as they essentially aerosolize the wearer's respiratory droplets.<ref name="healthgrades.com"/>
|-
| Disposable surgical mask || Diligent wearing in public spaces can significantly reduce the spread of respiratory infection.<ref name="healthgrades.com"/> || Not designed to be used more than once.<ref name="healthgrades.com"/>
