Awhile back, I had purchased glass storage jars at Ikea and just today I have found out they store the same capacity as my water distiller polycarb bottle. So try looking for glass storage jars. I also would never use the charcoal filter if you want to filter it use a countertop carbon filter with a kdf post filter to control bacteria, its expensive and I don't bother with it. Charcoal filters condition the water which I am going to start doing by adding clay salt and oil oregano shaking in and setting it in the sun
You can filter or treat water all you want prior to the distiller, the distilled water to mh is best with zero filter. He has seen that all filters will pollute the pure water.
Always just leave out the charcoal, you should be able to do this with all models
