Personally I love this : Cold Brew Coffee Maker - Coffee Gator Brewing Kit with Stainless Steel Measuring Scoop and Collapsible Loading Funnel - BPA-Free Filter and Glass Carafe - Black - 47oz https://www.amazon.com/dp/B01KZEO6HI/ref=cm_sw_r_cp_api_i_cY.3DbT77X7JF

Get a good burr grinder to get a nice course grind.

My favorite coffee is this: Portland Roasting Organic Dark Sumatra Whole Bean Coffee - USDA Certified - Carbon Neutral and Award Winning Roasters, 1 12oz. Bag https://www.amazon.com/dp/B00PJ8HT5W/ref=cm_sw_r_cp_api_i_tZ.3DbAKTD6ZR.

The only thing is with this you'll get some small fine particles that get thru the filter. I just run it thru my hot coffee maker with the top open through the white filter. It works.
