The AeroPress coffee maker is a really a terrific way to brew coffee. It is inexpensive, easy to use, easy to clean, and most importantly, it makes some amazing coffee.
The complete AeroPress kit can be found at online retailers , coffee shops, and specialty stores. You can also usually find replacement filter packs at these locations.
However, it can be a bit harder to find some replacement parts for the AeroPress. If you want to replace the plunger or chamber, you are stuck with ordering a whole new unit, which can be wasteful.
Thankfully http://www.aeropress.ca/ sells replacement parts that are shipped from Canada.
