• Figure 16b is a front view of the front face 1602 of exhalation filter cartridge 203.
• Figure 16c is a rear view of the rear face 1604 of the exhalation filter cartridge 203.
• a metal cap may be positioned at the bottom end of the foam core 1630 and HEPA filter 1624 to stop the downward flow of smoke and odor particles before being allowed to exit out the outlet cap 1628, and to force the smoke and odor particles laterally towards the filter casing 1622.
• the foam core 1630 may be infused with a odor capturing substance, e.g., odor absorbing materials such as Ecosorb® odor-absorbing products manufactured by OMI Industries. Citrus, mint and/or cinnamon extracts (or other extracts) can additionally or alternatively be added to the oil to provide a selection of scents.

• the inlet cap 1620 is positioned on the top side of the filter casing 1622 to form the front face 1602.
• the HEPA filter 1624 is positioned inside the filter casing 1622.
• An internal filter cap 1802 is positioned on the bottom side of the filter casing 1622 to support the HEPA filter 1624 and create an exhalation hole 1806 to allow exhaled air to pass therethrough.
• the foam core 1630 is positioned inside the HEPA filter 1624.
• the pipe 2100 includes a mouthpiece 2105, one-way exhalation vents 2215 on the front side 2253, and a flip- top lid 21 10 with one-way inhalation vents 2220 on the top side 2251.
• the mouthpiece 2105 is coupled to an inhalation path (not shown in Figures 22a-22d) and an exhalation path (also not shown in Figures 22a-22d). Each of the inhalation path and the exhalation path are described below with respect to Figures 24a-24f.
• the pipe 2100 may include a shutter 2320 and a shutter insert 2328 within the upper channel 231 1 of the body 2301.
• a shutter pivot clamp 2324, a fastener such as a screw 2326, and other connectors such as a shutter pin 2318 and a shutter spring 2320 may ensure that the shutter 2320 and the shutter insert 2328 are coupled to the upper channel 231 1 and that the shutter 2320 and the shutter insert 2328 are biased to a closed position.
• the shutter insert 2328 may comprise an aperture 2334 which allows a cigarette to pass from the upper passageway 2313 through shutter chamber 2336 to the chamber opening 2332.
• the shutter 2320 When the cigarette 2106 is inserted, the shutter 2320 may be deflected to an open position. As described in detail below, the shutter 2320 assists in limiting airflow to the cigarette 2106 when the cigarette 2106 reaches a predetermined length, such as the length of a conventional cigarette filter.
• Figure 24a illustrates a front view of the pipe 2100, and identifies plane B-B half way between the left and right sides of the front face. Figure 24a further illustrates the mouthpiece 2105 and the one-way exhalation vents 2215 residing on the front of the pipe 2100.
• Figure 24c illustrates an expanded view of the shutter chamber 2336 in Figure 24b.
• a shutter 2320 separates the shutter chamber 2336 from the combustion chamber 2408.
• the shutter 2320 may be positioned to substantially limit airflow through the inhalation path when the cigarette burns to a predetermined length.
• an internal spring (not shown) causes the shutter 2320 to return to a closed position. In the closed position, the shutter 2320 restricts airflow through the inhalation path of the pipe 2100.
• the shutter 2320 may be positioned to correspond to the filter length of the cigarette 2106.
• FIGS 25a-26c illustrate the internal details of an exhalation filter 2412, in accordance with an embodiment of the present invention.

• the foam core may be infused with a odor capturing substance, e.g., odor absorbing materials such as Ecosorb® odor-absorbing products manufactured by OMI Industries. Citrus, mint, and/or cinnamon extracts (or other extracts) can additionally or alternatively be added to the oil to provide a selection of scents.
• the filter body end cap 2508 is configured to enclose the foam filter 2506 and the pleated cartridge 2516 within the filter body 2518.
• the valve spring 2514 biases the valve piston 2512 and O-ring 2508 against the filter body cap 2508, thereby creating a one-way exhalation valve within the filter 2412.
• Figure 25b illustrates a side view of the exhalation filter 2412.
• the filter body 2518 has a length of 2.480 inches.

• the end block 2708 fits into the body 2716.
• a power block 2710 rests on the end block 2708 within the body 2716 for powering a resistive heating element (not shown) for igniting the cigarette 2106.
• Electrical posts 2724 are coupled to a contact block 2718, which in turn is coupled to the power block 2710.
• the electrical posts 2724 extend alongside the cigarette 2106 when inserted.
• the power block 2710 comprises a battery or other power source that supplies electrical energy to the resistive heating element.

• Embodiments of the present invention preserve the commonplace and enjoyable experience of smoking and reduce or eliminate the adverse effects of secondhand and thirdhand smoke. For instance, embodiments of the present invention reduce or eliminate the odors and particulate matter that get into hair, clothing, and other surfaces, related to thirdhand smoke. Further, embodiments of the present invention reduce or eliminate the amount of nicotine, THC, tar, smoke, particulate matter, and/or other chemicals that adversely affect the health of non- smokers who are near smokers. The health of non-smoking friends and family members is therefore beneficially enhanced. Embodiments of the present invention therefore allow smokers to enjoy the recreational, ritual, spiritual, medical, and other purposes of smoking without the environmental and health effects of secondhand and thirdhand smoke.
