Hi Jonnie,
We truly admire your professionalism as an attorney and thank you for bringing attention to this topic.
For Snapmaker, responsibility and safety are our top priorities, that’s why we are taking a step further to make this first air purifier for 3DP and laser in the first place, and we hold every word accountable. However, it doesn’t mean we’re not confident with our products.
Regarding the first question,
- Does Snapmaker believe that its Air Purifier product is safe to use entirely indoors? In other words, does it actually do what it claims to do in terms of filtering the air and “purifying” it?
The reason why we recommend: “connecting the hose on the Enclosure to the Air Inlet, and the new hose to the Air Outlet. Secure all hose clamps. Put the unattached end of the hose outdoors” in the quick start guide is to ensure the ultimate safety for all users and in all situations.
On the one hand, based on our research, every country has different standards of indoor emission, which is hard to align. On the other hand, the emission generated during the process of 3D printing and laser cutting & engraving depends on the material used, and how the user uses the machine. However, we have no control over this, which makes it hard to determine the exact effect they have on the human body even after filtration.
It is not an issue about “if we believe our product is safe to use entirely indoors”, but if we are believers of science and probability.
Regarding the second question,
- Is Snapmaker willing to agree that such use is not “unintended” without the qualifying/liability-limiting language currently in the product literature?
Based on the above-mentioned reasons, our choice of words was careful with the responsible considerations of all possible circumstances.
The Air Cartridge was testified and proven by authoritative third-party organizations, mainly on the main emission generated from 3D printing and laser cutting & engraving process including the VOCs and PM. Among similar products with the same price range in the market, our Air Cartridge has a high 95.9% filtration efficiency (PM0.3-0.5). Feel free to check out the full reports here.
Hope this answers your questions and thanks for your attention and support for Snapmaker.
Best regards,
Team Snapmaker
