Can I clean and reuse this filter?

Yes. The panel design is cleanable — just tap it out or gently blow compressed air through it. You'll get multiple service cycles before needing replacement.

Does this fit both Civic and HR-V exactly the same way?

Both models use the same air box mounting for these years. Drop it in where your factory filter sits — no brackets or hardware changes needed.

Will this affect my fuel economy or performance?

A cleaner filter lets your engine breathe easier. You'll notice sharper response if your stock filter was heavily loaded. Fuel economy stays the same or improves slightly.
