There is no PH or wave maker that is anemone safe. You just have to know your anemone so you can provide condition that they are happy. They won't move if they are happy. I use exclusively Vortex MP-60, MP-40 and MP-10, plus Koralia PH for flow in my various tanks. All without any protection of the intake or any screen to keep anemone out (which does not work anyway)
