I picked up this washable HEPA filter for my RV50 Pro Omni, and it fits exactly as expected. Swapping it in was quick, and suction seems back to normal after a few weeks of daily runs. Being able to rinse it instead of buying disposables is the main draw for me, though it does need to dry fully before you put it back. Good for anyone with pets or dust, just remember it is a filter, not a magic fix for everything.
