The filter allows the oils to pass through. AFAIK, the benefit of an Aeropress , using the inverted method, is this: the hot water is in contact with the grounds for 15 seconds before being pressed out into your cup, which is long enough to get all the goodness of the ground beans, but not too long to extract the bitterness.

(Inverted method (look it up on youtube): you put the 2 halves of the Aeropress together, turn it upside-down, pour in the grinds, add hot water, stir for 15 seconds, screw on the filter lid, turn the whole thing carefully over to the top of your cup, and press. Then fill your cup the rest of the way up with hot water. Enjoy! see less I've been using the Aeropress for many years ("inverted" method), with a fine stainless steel mesh filter.

Hi, Connie. Every Aeropress is made almost entirely out of plastic. It is, however, BPA free.

No. It's plastic so it doesn't show up on their screens. Most baristas will travel with it and I've never heard of anyone having problems. In fact check out #milehighaeropressclub on Instagram/twitter for baristas using it on airplanes.

I use a regular coffee cup to press the coffee into. However, first test the cup to make sure it's big enough! I have an extra giant mug that I press the coffee into and then add the water.

I hope this answers your question and didn't confuse you!
By the way, I have to turn mine upside down so the coffee doesn't filter our before I'm ready to press. The plunger is on the bottom and then when I'm ready to press, I turn it over on to the cup I'm going to use. I saw a barista do that and it made sense after I did it the way the Aeropress video...and it didn't work for me. see less I use a regular coffee cup to press the coffee into.
