I used to use the syringe filters all the time too and it got old. I started using Autofil 250ml .22um full assemblies. I got them on amazon in a 12 pack. If has the nipple you're talking about and it hooks up to a vacuum source. I use a hand pump like you'd use to bleed brakes on a car. I can filter 250ml in less than 10 minutes now. It used to take me a little over an hour to do 200ml before with syringe filters. Just be careful not to use too much vacuum pressure or it will crack the bottom of the bottles.
