The MeeBaa Manifesto: Why We Use Open Standards

Why should you buy MeeBaa S01A-9Bar, S01B-9Bar?

At MeeBaa, we believe that an espresso machine should be a long term use machine, not a disposable appliance. One of the biggest frustrations in the manual espresso world is the "Proprietary Trap"—buying a machine today only to find that you can’t get replacement seals or filters five years from now because the brand changed their design or disappeared.

We are doing things differently.

1. Transparent Engineering, Universal Parts

The MeeBaa S01 series is designed around industrial standards. This means that the most common "wearable" parts—the components that interact with heat, pressure, and coffee oils—are not secret, custom-molded shapes. They are precision industrial components.

• Piston O-Rings: Our piston uses standard FDA-compliant food-grade silicone rings. Fitting the piston, take the ring size as 20mm OD and thickness 1.2mm, 1.5mm to 1.8mm.
• Filter Stacks: Our 34mm and 35mm sintered and woven filters are based on high-tolerance industrial specifications. Spec: Thickness of 1.7mm, 2mm, 3mm, 4mm or 5mm are all good. The other one, spec: the powder sintered, high pore density filters have 34mm, or 35mm, thickness of 2mm, 3mm, 4mm or 5mm, and they are for higher resistance, and therefore a companion for a much coarser grind size coffee ground.

2. The Freedom to Choose

We believe you should own your machine, not just license it. If you are in a pinch or like to experiment:

• Find them anywhere: If we are not currently stocking a specific filter or ring, we want you to keep brewing. Because we use standard dimensions, these parts can often be sourced from high-quality industrial suppliers or specialized marketplaces.
• Our Open Recommendation: Even if you don't buy from us, we will provide the specifications you need to find a "matching" part that fits the S01A, S01B’s tolerances. We would rather you find a part elsewhere than have your machine sit idle.

3. Why Buy From the MeeBaa Listing?

While we embrace "openness," there is a reason most of our users still choose our curated sets. When you buy a filter or a seal directly from the meebaa.store or our eBay listing, you are paying for Curation and Verification:

• Tested for 9-Bar Loads: We have tested every part to ensure it handles the 29kg of downward force required for a perfect shot.
• The Right Micron Rating: Not all sintered filters are equal. We’ve done the to find the exact pore sizes that prevent "choking" while the grind size is too fine and while you are maximizing flavor clarity.
• Precision Fit: We ensure the OD (Outer Diameter) and ID (Inner Diameter) are exact for our high-tolerance pressure vessels, saving you the risk of buying a part that is "almost" right but leaks under pressure.

The Bottom Line

Our goal isn't to lock you into a subscription of parts. Our goal is to provide the best manual espresso platform in the world. By using open industrial standards, we ensure the MeeBaa S01B-9BAR remains a reliable, maintainable, and "future-proof" tool for your kitchen. In general we offer a lower price on the parts in our listing, for now, the ebay listings.

We provide the good product, you buy it, use it for your enjoyment.
