the size of the machine is irrelevant, the beam wavelength is what matters. Look for glasses rated for 10.6 um, and I wouldn’t recommend buying the cheapest pair you can find. You only get 2 eyes…
ANy pair of acrylic safety glasses will block the wavelength of a C02 laser. An unfocused beam at 18" away takes approx 6 seconds to burn through the acrylic. If you are staring into the beam for longer than that then Darwin will take care of things for you. 
I bought my from here. https://www.uvex-laservision.de/en/laser-safety-eyewear/

As AB says any pair of acrylic safety glasses will work BUT…
My brain told me that my eyes were precious so I purchased the proper goggles with a 5+ OD rating at the 10.6um wavelength. Are your eyes worth it ?
If you follow proper safety proceduyres such has having lid interlocks in place, the standard glasses should be fine. But as others have said, it is your only pair of eyes, treat them nicely.
