FAQ
AeroPress Steel Coffee Maker
Is AeroPress Steel dishwasher-safe?
Yes, AeroPress Steel is dishwasher-safe. If you don’t have a dishwasher, you can also clean it by hand
with lukewarm water, 8entle soap, and a gentle cloth every week.
Does the stainless steel chamber get hot?
No, because the chamber is double-wall stainless steel, it does not get hot.
Does AeroPress Steel lose significant amounts of heat due to its all-Stainless-Steel design?
No. In fact, AeroPress Steel retains heat better than other AeroPress coffee makers. In brewing,temperafure is typically lost in two ways. First, when hot water is added and first contacts the chamberwall, then second, while the coffee is brewing during the immersion part of the process, heat is lost to thesurrounding air. Due to AeroPress Steel’s unique vacuum-insulated double-wall design, less heat isabsorbed by the brewing chamber when the hof water is first added, resulfing in a higher initial brewtemperature. The double-wall design also provides insulation, which keeps the coffee hot longer duringthe brew process. Note: Preheating any chamber will raise the starting brew temperature, but it does notsignificantly change the rate of heat loss.
Is the Steel meant for travel?
Yes, because it’s made from durable stainless steel, AeroPress Steel is a great option for travel, yourhome kitchen, or anywhere you need great
My Steel filter cap gets hot after brewing. What do I do?
You can let it sit for just a few moments, run the filfer cap under cool water before removing if from the
chamber or you can use a cloth to remove it.
What materials go into making AeroPress Steel?
The chamber, plunger, filter cap, scoop and stirrer are made of professional-8rade 304 stainless steel.
The plunger seal is made of LFGB-grade silicone.
What is 304 stainless steel? Is it the same as 18/8 stainless steel?
304 stainless steel is a professional-8rade, food-safe stainless steel alloy known for its strength,durability, and corrosion resistance. It contains approximately 18% chromium and 8% nickel – which iswhy you may also see it referred to as “18/8” stainless steel. In fact, 18/8 and 304 are often usedinterchangeably; 18/8 simply describes the minimum chromium and nickel content within the 304specification range. Because of its excellent resistance to rust and staining, along with its ability tohandle repeated heating and cooling, 304 stainless steel is widely used in food and beverageequipment, commercial kitchens, medical tools, and other demanding everyday applications. It’s stron8,stable, and built to last – making it an ideal material for brewing exceptional coffee.
Why is AeroPress Steel manufactured with professional-grade 304 stainless steel?
We chose 304 stainless steel because it delivers the ideal balance of durability, corrosion resistance, food safety, and manufacturability for a precision coffee press. 304 is exceptionally resistant to rust and staining, making it perfect for repeated exposure to hot water and daily use. It’s also strong and impact-resistant, helping the AeroPress Steel stand up to years of brewing at home or on the go. Just as important, 304 stainless steel is easier to form and weld than many alternative alloys. That matters in a product like AeroPress Steel, where tight tolerances and precise assembly are essential to ensuring a consistent seal and dependable performance. You may see other brands describe their stainless steel as “18/8” or even “aerospace grade.” In practice, 18/8 is simply another way of describing 304 stainless steel. While 304 can be used in certain non-structural aerospace components, it is not typically selected for high-stress aircraft structures because aerospace engineering prioritizes extremely high strength-to-weight ratios and specialized alloys. For a coffee press, however, 304 stainless steel is exactly the right material — durable, corrosion-resistant, food-safe, and built for everyday performance.
Why does AeroPress Steel use vacuum-insulated double-wall construction instead of standard double-
wall construction?
A vacuum-insulated double-wall chamber reduces heat transfer far more effectively than a standarddouble wall because the air between the walls is removed, minimizing conductive and convective heatloss. This helps maintain a higher, more stable brewing temperature throughout immersion, supportingbetter brew control.
What is the capacity of AeroPress Steel?
The Steel chamber holds up to 12 oz, 20% more capacity than AeroPress Original, Clear, Premium and Go Plus.
I noticed that my AeroPress Steel seal stays compressed inside the chamber when I store it with the
plunger inside. Is that a problem?
No – this is completely normal and won’t damage your seal. Early AeroPress models used naturalrubber seals that could wear out faster if stored compressed inside the chamber, but the currentAeroPress Steel uses a durable silicone seal that doesn’t fatigue under compression. You can safely storeyour plunger inside the chamber without affecting the seal’s lifespan.
Can I use the standard-size AeroPress Flow Control Cap with AeroPress Steel?
Yes, AeroPress Steel is compatible with the standard-size AeroPress Flow Control Cap

The paper filter sticks to the filter cap. How do I remove it?
Gently brush the end of the stirrer across the paper filter in the cap. This makes the paper curl up for easy removal.
