Just FYI, filament can arrive fresh from the vacuum bag with a whole range of moisture contents. Some may print ok and some may need drying before it will print well.
I’m not familiar with the A1 but some let you use the heated bed as a filament dryer. There’s also lots of consumer filament dryers. Just know if your ambient humidity is high, the standard dryers are of limited utility but could get your PLA into good printing.
There’s a number of threads here on filament storage. If ambient humidity is low, some are fine with open storage. Others use sealed plastic bins and cereal boxes. I’ve gotten to like the cereal boxes but they increase space requirements. A lot depends on how big a problem humidity is for you.

Filament moisture is quite a topic and lots of takes here. Just search for filament moisture and filament drying in the search. But it’s not too bad.
