Dyson Purifier HP09 Formaldehyde catalytic filters

So I just bought my third HP09 Formaldehyde and this one has the old catalytic filters the metal ones you see on Dyson website and packaging.  My two older machines has the newer filter that is more of a stepped material.


should I be worried I may have a really old machine with older technology?  I know Dyson state the machines are now sealed to H13 inside as well as the filters.  Would the older machines be sealed to H13?


Thank you

@Rainey Absolutely, all of that line has the fully-sealed HEPA standard and the same filtration/purification capacities. Thanks for your post.
