Knowsmoke is a California-based technology company dedicated to establishing a universal standard for residual smoke detection in all shared, indoor spaces. Since its inception in 2021, Knowsmoke has secured a dominant position in the residual smoke detection industry by offering safe, user-friendly products for vehicles and common living spaces. Trusted by thousands of customers, Knowsmoke products are distributed by the largest and most reputable online retailers worldwide.
Knowsmoke's founders recognized the challenge rental companies faced in enforcing smoking violations without substantial physical evidence and set out to develop a solution for smoke residue detection. During their research, they discovered a body of work defining this residue as thirdhand smoke, which significantly shaped their approach.
Thirdhand smoke contamination and exposure represent a public health crisis. More than 1.2 billion shared, indoor spaces globally are vulnerable to exposure without consequence, jeopardizing the health and well-being of billions. The health risks associated with thirdhand smoke disproportionately affect our most vulnerable communities, highlighting the urgent need for protection.
