Abstract
Disclosed are washcoated ceramic honeycomb filters. The ceramic filters exhibit a relatively high level of washcoat loading while exhibiting minimized levels of backpressure. Also disclosed are methods for manufacturing the washcoated ceramic honeycomb filters. The method comprises providing an cell geometry derived from a predetermined level of washcoat loading to be applied to the ceramic honeycomb article.
