ONGROK Plant-Based Air Filter

Ideal for festivals, concerts, or anywhere smoking is allowed, the ONGROK Plant-Based Air Filter is a personal biodegradable air filter for smokers on the go.
To use this small, handheld filter, take a puff of your cigarette, joint, water pipe, or vape pen and exhale through the filter so those around you aren't bothered by the smoke. This is a fully degradable air filter made almost entirely of corn starch that has a lifespan of about 300 uses for cigarettes, 600 uses for cigar products, and 900 uses for vape pens. 
When disposing of the hepa-grade personal filter, remove the silicone band and mouthpiece first. The filter will fully degrade within 9 months, regardless of whether you discard it in a compost facility or a natural environment.
