How is the Rosh Filter protecting me ?

Our research team tested the effectiveness of the ROSH Filter at Reputable Labs in the United States, and we are listing a few chemicals to help consumers understand the ROSH filter's performance.

• Acenaphthylene is produced during the smoking of waterpipe charcoal.
• Toxicity: Acenaphthylene is known to cause oxidative stress, a key factor in the development of lung damage and chronic obstructive pulmonary disease (COPD).

When applying Rosh Filter to Shisha, Acenaphthylene exposure was reduced by 95 %

• Methylnaphthalenes (1-methylnaphthalene and 2-methylnaphthalene) are found in shisha (hookah) smoke.  Exposure to these compounds can lead to chronic obstructive pulmonary disease (COPD), bronchitis, and loss of lung function.

• Methylnaphthalenes are associated with increased risk of  cancers, including lung, oral, esophageal, stomach, and bladder cancer.

When applying Rosh Filter to shisha, 2-methylnaphthalene exposure was reduced by 97% for Ajami and 94% for Moassal. 

Other Harmful Chemicals in Shisha

• Shisha smoke contains over 4,800 different chemicals, at least 69 of which are known human carcinogens
• Benzene: Linked to leukemia; levels in shisha can be over 6 times higher than in cigarettes. 
• Nitrosamines are among the most potent carcinogens found in shisha smoke. These chemicals form during tobacco leaf processing and are released when the tobacco is heated. 
• Volatile Aldehydes which can lead to lung cancer and leukemia.
• Heavy Metals: Arsenic, chromium, lead, and nickel, which contribute to various cancers and respiratory diseases.

Phenanthrene

• Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) that is found in shisha (hookah/waterpipe) smoke. Phenanthrene is a key biomarker for exposure and is studied by scientists as a representative of the concentrations of toxic mixtures that are inhaled by shisha users. 

The use of Rosh Filter will reduce the percentage of Phenanthrene by 95% for AJAMI and 94% for the Moassal.
