Do I need a UV/IR filter?

That sensor is very sensitive in the IR as its sales pitch outlines. Use it without if you are doing planetary stuff with Saturn Jupiter etc as it will pick out the IR emissions in those objects well. Plenty of help for that aspect on the Tube and other forums if you want to have a go. It will change output colours as already mentioned here.
Otherwise strap a filter on and forget it. A filter will sharpen stars if you use the sensor for guiding or deep sky objects as I have. see attached.

clear skies….

I've just bought a new ZWO ASI224MC camera, which doesn't have a UV/IR cut filter, do I need one?

I use this camera for planetary photography. 

Recently used it and wondered why the results were so rubbish, then discovered I’d not put the filter on😬.

So would say it’s essential.
