When it comes to filters, Savinelli Balsa takes an out of the box approach. Instead of filtering the smoke as it passes through, balsa filters allow the smoke to pass around the wood, absorbing extra moisture and tars, providing an extra cool, dry smoke. You can even reuse Savinelli Balsa filters several times by simply rinsing them under water. Perfect for smoking moist tobacco, Savinelli balsa filters are easy and effective. Available in 6mm and 9mm.
