I suggest you wearing a half-face respirator with two air vents on both sides of your nose. This respirator covers the mouth and nose. It does not suffocate you, allowing you to breathe easily. Yet, you have to avoid the fumes from the spray that may be harmful. The first thing you need to do is to pick up the spray you want to use. After that, you need to read the active ingredients. If you like them, you can buy the product. Only after you purchase it, you can buy a protective mask, considering the compounds of the spray. Organic ingredients do not require extra protection, unlike chemicals.
