ATHIA Portable Siphon Coffee Maker, 400 mL

The ATHIA Portable Siphon Coffee Maker is a 400 mL manual travel brewer for hot coffee, cold brew, and loose-leaf tea. I’d choose it for keeping a hands-on coffee routine on the road without packing a bulky machine.

Why I like it

I like that this is built around portability rather than trying to turn a kitchen setup into travel gear. At a stated 180 g, the lightweight, stackable design makes sense for a hotel stay, road trip, or camping kit. The BPA-free Tritan construction also avoids the fragility of a glass brewer when I’m packing a bag.

ATHIA calls its brewing system Airsiphon. It uses gravity and pressure differences to guide coffee through an internal flow path, with no pumping or pressing. I’d think of it as siphon-inspired manual brewing rather than assume it works like a traditional heated glass vacuum pot. The visible flow gives me something to watch while I take a break and make my coffee.

The removable, reusable metal filter is another reason I’d consider it for travel. I can build a routine around cleaning and reusing the filter instead of keeping track of paper filters. I’d start with the manufacturer’s recipe, then change one variable at a time to find the cup I prefer. Being able to switch between coffee and loose-leaf tea also gives this one compact setup a little more flexibility.

Good to know

Does it heat water?
This is a manual brewer, not an electric kettle. I’d plan a separate way to prepare water for hot coffee and follow ATHIA’s temperature guidance.

Do I need paper filters?
No. It uses a reusable metal filter. I’d clean it after brewing so residue doesn’t carry into the next cup.

Is 400 mL the finished coffee yield?
That is the stated bottle capacity. I’d use ATHIA’s fill guidance and recipe rather than assume every brew produces that exact volume.
