Hi
Looking for some help.
I have a spare TT prep machine for travelling. Two weeks ago I opened a new filter and used the machine for 3 days and ran an emptying cycle. I have left the filter in the machine but have not used it since. I am due to travel to see family this week coming. Will this same filter be okay to use again if it's been in the empty machine or will I need to install a new one?
Thank you x
