The most common filter is made of cordierite. Cordierite filters provide excellent filtration efficiency, are relatively inexpensive (comparison with Sic wall flow filter). The major drawback is that cordierite has a relatively low melting point.

Coating Difference
| With coating | Without coating |
|---|---|
| Noble metals (such as platinum, palladium) or metal oxides (such as CeO₂, ZrO₂) are usually coated as catalysts to promote the oxidation reaction of particulate matter (PM). It can passively regenerate through catalytic reaction at a lower temperature (about 250 - 350°C), convert soot into CO₂ and reduce the frequency of active regeneration (high temperature combustion). It can catalyze the conversion of NOₓ at the same time (such as SCR function) to achieve coordinated treatment of multiple pollutants. | It only relies on physical filtration and needs to actively regenerate and burn soot at high temperature (about 550 - 650°C), which has higher energy consumption and strict requirements on engine operating conditions. It cannot handle gaseous pollutants such as NOₓ. |
| High passive regeneration efficiency and reduced fuel consumption (reduced fuel injection for active regeneration), suitable for frequent start - stop or low temperature conditions (such as urban roads). |
Fully dependent on active regeneration, requiring engine adjustments (post - injection of fuel) to increase exhaust temperatures, potentially increasing fuel consumption and thermal stress. |

Shipping
We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
About Customization
x| First | Please tell us what you want to do (ceramic or metal catalyst or DPF, DOC, DPF) |
| Second | Please tell us the customized material, coating requirements, CPSI, purchase quantity, etc |
| Third | If it is a custom metal package, a custom drawing is required |
| Fourth | If the catalyst is customized, there are numerical requirements for PD, PT, RH, and the minimum sample is 3 |
| Proin Fifth | If you need to customize the three-way catalyst assembly (the whole exhaust pipe) if we don't have a sample, you need to provide a sample to us |
