I'd recommend a PAR filter, but you are really going to be hard pressed finding a reasonably priced filter that will (a) filter out that signal AND (b) do so without having a significantly adverse effect on performance on 153 Mhz.
The ~70 dollar PAR filter for 152 Mhz has a notch of 35 db with you still being down about 3 db at 2.29 Mhz +- 152.840.
So, at minimum you'd be 3 db down between 150.55 and 155.15. Of course, 3db down isn't much... but the attenulatioon increases much faster the closer you get to the center freq.

So you'll have to weigh just how much attenuation you are willing to incur at your listening frequencies. If they are strong repeater frequencies, then you likely will hvae no trouble continuing to hear them even with some attenuation.
Dale can center it on any freq you want. He can also create a filter with a narrower notch, but at a significantly increased cost (think commercial filter).
But I do recommend the PARs. He built one for me to wipe out TV Ch 9 . It works superbly.
