You can update any Honda GCV mower engine (HRR, HRX) to the better 2-stage air cleaner and filters used on the Honda HRC215, which uses the commercial-grade GSV160 engine. You need the two filters, the screen grid, and the deeper air filter outer cover. The extra foam element acts like a pre-cleaner and can be easily cleaned and re-oiled:

The shop manual says to use regular 10W-30 engine oil on the foam element, but Honda offers a MOTUL oil just for this application. It is more sticky and water-repellent than just engine oil: 4 ounce bottle is part number 08207-MTL-100, $7.56.
