the charcoal filters comprise 0.2 and 0.3 g of BS 44/52, 0.2 and 0.3 g of BS 52/60, 0.15 and 0.2 g of BS 60/72, 0.1 and 0.15 g of BS 72/85, a mixture of 0.2 g of BS 44/52 and 0.1 g of BS 52/60, a mixture of 0.2 g of BS 44/52 and 0.1 g of BS 60/72, a mixture of 0.1 g of BS 44/52 and 0.1 g of BS 72/85, a mixture of 0.2 g of BS 44/52 and 0.1 g of BS 72/85, a mixture of 0.15 g of BS 44/52 and 0.1 g of BS 72/85, a mixture of 0.1 g of BS 52/60 and 0.1 g of BS 60/72, a mixture of 0.1 g of BS 52/60 and 0.1 g of 72/85, and a mixture of 0.1 g of BS 60/ Table 1 shows that the charcoal filter cigarettes mentioned in this invention are very effective for markedly reducing the content of p-BSQ, the major hazardous oxidant present in the mainstream smoke
In their design, an air chamber is added to the acetate and charcoal sections
The S804R is accounted for up to 220 puffs and more than 300 recharge cycles
