Looking for quality colour filters (for use on Monochrom)

[Sjak]

I've been using the Monochrom for 1.5 year now as my main camera. I notice that I tend to use an orange filter most of the time on sunny days.

Unfortunately, I have not been able to find high quality filters locally. The main issue is that dust tends to stick on it and is hard to remove, even with a lens-brush or microfiber lens cleaning cloth.

What brand has (coated?) colour filters of good quality?

Thanks so much! Didn't know B+W still made colour filters, these didnt show up at my local dealers. Will order a selection for my most used lenses (I hate fiddling with step-up/down-rings)
