4-Pack Mini Hygrometer Thermometer Indoor Outdoor Round Humidity Meter, Small Digital LCD Monitor Thermometer Temperature Gauge Humidity Sensor (℉) or (℃) for Reptile Thermostat, Jars

My house is typically 50 to 60% RH. In order to reduce or remove a factor that can make a print bad, I always dry my filament and keep it in a cereal box. Here is what I do. Note that there a bunch of options in the cereal box category - choose something that works for you. I use this food dehydrator to dry my filament: https://amazon.com/Elite-Gourmet-Dehydrator-BPA-Free-Stackable/dp/B08BSQZ2LS/ I printed 4 of the "285mm x 180mm x 90DEG" models to be able to dehydrate 2 spools at once: https://www.printables.com/model/344695-parametric-dehydrator-filament-dryer-up-to-10-x-1k I bought these to store the filament after it is dried or between printing: https://www.amazon.com/dp/B0BHVT9PV1 These for monitoring the humidity in the box: https://www.amazon.com/dp/B0DG8ZXZ5D This for keeping the spools dry in the container: https://www.amazon.com/dp/B0F6L7PS6X Print these for holding the silica, spool and hygrometer: https://makerworld.com/en/models/820876-modular-filament-storage-for-dry-box-desiccant-box

I suppose it might depend on what you mean by good. If you live in a place with little humidity, then sure. However, you should still dry your filament before using it. After that, you need to keep it dry. I'm not saying this is what you need to do but consider the concepts.

There are a large number of cereal box solutions that include the ability to print from the box. I have many more than 6 spools dried and ready. https://www.amazon.com/dp/B0BHVT9PV1 These for monitoring the humidity in the box: https://www.amazon.com/dp/B0DG8ZXZ5D This for keeping the spools dry in the container: https://www.amazon.com/dp/B0F6L7PS6X Print these for holding the silica, spool and hygrometer: https://makerworld.com/en/models/820876-modular-filament-storage-for-dry-box-desiccant-box

You can get little hygrometers like this on amazon all day long for pretty cheap. I use a bunch of them installed in cereal boxes for 3d printer filament. Haven't started storing ammo in a humidity controlled box though... Go through it too fast These are the ones I used https://www.amazon.com/Hygrometer-Humidity-Thermometer-Fahrenheit-Thermostat/dp/B0DNKGBW54/ And these are pretty similar to OP's https://www.amazon.com/Hygrometer-Thermometer-Humidity-Temperature-Thermostat/dp/B0DG8ZXZ5D
