Emission factors on a per-fuel, per-task, and per-energy-delivered basis for PM2.5 and CO from traditional chimney stoves burning wood (n=15) and the THU semi-gasifier stoves burning pelletized biomass (n=16), 6 months post-stove installation.

THU Stove Mean ± St Dev(ISO Tier) |
|---|---|---|
| PM2.5 (g/kg-fuel) | 2.3 ± 1.6 | 0.9 ± 0.9 |
| PM2.5 (g/task) | 3.7 ± 3.3 | 0.5 ± 0.4 |
| PM2.5 (g/MJda) | 0.612 ± 0.457 (1) | 0.123 ± 0.125 (3) |
| CO (g/kg-fuel) | 53 ± 17 | 49 ± 25 |
| CO (g/task) | 88 ± 49 | 31 ± 21 |
| CO (g/MJd) | 14 ± 5 (1) | 7 ± 4 (4) |
