Who complains about a 30MB memory usage increase these days? Who even notices? This is not Mac OS 9, it doesn't matter what your app's memory footprint is (within reason).
I expect Core Image is caching stuff for future use - blurs for example are expensive to set up. Might be worth comparing the time taken to execute the first time this is called with subsequent times - if there's a worthwhile speed up you can claim it as a feature - classic speed vs. memory tradeoff.
