Inā ua uhi ʻia ka DPF me ka metala makamae (e like me Pt, Pd a me Rh), e hele ka uahi ʻeleʻele me nā ʻāpana kalapona mai ka mīkini diesel ma o kahi paipu kūikawā a komo i loko o ke kānana. Hoʻopili ʻia ka ʻāpana uahi kalapona i ke kānana i hana ʻia me ka fiber metala, i ka wā e hele ana i ka hoʻonohonoho paʻa o loko a me ke kānana ʻano ʻeke. Ke hiki ka omo ʻana o nā ʻāpana i kekahi kekelē, e hoʻā ʻia ka mea puhi huelo e puhi aunoa. I kēia hihia, ua puhi ʻia nā ʻāpana i omo ʻia a hoʻolilo ʻia i CO2 ʻawaʻawa ʻole a laila hoʻokuʻu ʻia. Ua hoʻolālā ʻia ka hāmeʻa piha e like me ke ʻano lumi pālua, a ke hele nei ka kānana a me ka hana hou ʻana ma nā wahi like ʻole, e hoʻolilo iā lākou i mea ʻaʻole hoʻopilikia ʻia. Hiki i ka ʻōnaehana ke hana aunoa i kēlā me kēia kūlana hana o ka mīkini. Hana kūikawā ʻia ka kānana ʻāpana keramika honeycomb, hana ma ke ʻano he mea hopu i ka ʻāpana i kekahi ʻano.
