We fixed the bug on v3.25! Just testing it, and everything goes according to plan. Select Pure Mode, select Carbon Filtration ... it will maintain 96% all the time. As it should. So here's a question. Do you run v3.25? If so, please let me know via iStillMessage@gmail.com and we will ship you a new computer ASAP. A new computer with the new firmware in place. Under the understanding you will sent back the old computer containing v3.25. "Okay," you may say, "but I don't use the carbon filter, so why change the computer?" If you don't use the filter, disconnect the tube that leads to the filter ... and use it as your hearts collection tube to create a different take-off path for heads as compared to hearts ... Darn, we need to get that tablet functionality in place, so we can sent you new programming digitaly instead of physicaly!
