You're welcome. As said though only way to tell with any real degree of certainty if they are analogous to M1 is to cut one open for autopsy. SFX description and promo yt in link 'seem' to make it look that way, but the latter are not generally noted for their accuracy. JD's purchase should provide more information. ~$6 looks to be standard shipping cost up $75 purchase, 10 filters, beyond that free. But hey, they will throw in a free pair of disposable nitrile gloves. Wonder if that's one for each filter.
Beyond that it has a different different color, which means next to nothing for me as it's unseen after installation, in my applications at least. Based on a search SFX looks to have very limited availability.
