The partnership with the Last Prisoner Project will help continue the organization’s mission to expunge records for non-violent cannabis offenses and enact criminal justice reform

San Diego, CAPhilter Labs, Inc. — the first and only technology-enabled filtration company to pioneer a new category of micro-sized personal air filters to eliminate 97% of airborne contaminants and secondhand smoke and smell – announced today they are partnering with the criminal justice reform advocacy group, Last Prisoner Project, to donate a portion of their July and August sales from Philter products purchased to the group to further their mission. 

Over 600,000 people have been arrested in the United States for simple possession of marijuana. Approximately 46.9% of those arrested were Black or Latino people despite only making up 31.5% of the U.S. population. With a focus on personal rights and freedoms, Philter Labs identified a synergy with The Last Prisoner Project which is helping to lead the effort to reform outdated and unjust cannabis laws while helping people get their lives back. 

“We launched The PHILTER Project to partner with organizations that are at the forefront of creating the change our society needs,” said Amanda Byrd, Chief Marketing Officer at Philter Labs. “No one should be behind bars for the simple possession of marijuana – especially as legalization continues to spread through the country – it’s time for our laws to catch up.”

The Last Prisoner Project (LPP) is a coalition of cannabis industry leaders, executives and artists dedicated to bringing restorative justice to the cannabis industry. LPP is dedicated to releasing those incarcerated for marijuana offenses and helping to rebuild their lives. The advocacy group works to release individuals, get their records cleared, provide programs that build pathways to employment and work at the Federal and state level to advocate for common sense criminal justice reforms.

“We are dedicated to releasing cannabis prisoners and helping them rebuild their lives.” said Mary Bailey, Managing Director at Last Prisoner Project. “People are profiting from legal cannabis daily despite thousands of people being incarcerated for the same thing. Our goal is to ensure their freedom and fight for a fair and just society for everyone.”

The PHILTER Project will donate a percentage of proceeds from PHILTER products purchased through August at no extra cost to their customers. The social responsibility and advocacy division of Philter Labs, their goal is to give back and help improve communities throughout the country. Their April partnership with global reforestation non-profit, One Tree Planted, helped to plant over 1,000 trees in the Amazon Rainforest, and in May, provided veterans suffering from combat related PTSD free PHILTER Pockets to reduce the stigma associated with vaping cannabis through a partnership with the Veterans Cannabis Group. Last month, The PHILTER Project donated $1,000 worth of meals via The Okra Project to Black Trans people experiencing food insecurity.

Philter Labs’ next-generation filtration technology, crafted by a team of industry experts, scientists and engineers, is specifically designed to reduce the impact of secondhand smoke and shift the culture of vaping and smoking to one that focuses on collective social responsibility.
