Sure.
You have some BHO that might benefit from winterization. Pretty sure you’re not going to be impressed with the results of simply winterizing that…
@TheWillBilly’s brita trick might well change that…it’s not conceptually far from @TheLostBiologist’s tek @Akoyeh bought to your attention (might even be DE along with the AC in there…)
Below is an EHO shatter. Essentially a qwet filtered over AC/DE.
insisting on calling winterization “practice” for QWET is not (imo) helping your understanding…but I’ll give up on that one for now.
You could certainly use it as brita practice…
