  >And a less obvious application is in an easy-to-clean filter: stretch this filter and its pores grow, allowing stuff stuck in them to be flushed through when the filter is washed.

  That doesn't make sense to me. If the auxetic threads making up the filter expand, then the negative space between them will shrink, so you'll get smaller pores, not larger ones.
