Use a refillable atomizer according to its device guide and the fragrance's directions. Refilling, spraying and cleaning are different tasks that depend on the actual mechanism.
A HUME Fragrance buying guide

Identify the design
Bottom-fill, cartridge and screw-top systems require different handling. Do not follow a guessed universal procedure.
Keep the scent identified
Label current contents and avoid adding another perfume to unknown leftovers.
Apply considerately
A portable device is still a spray source. Keep application away from shared air and protect the closure afterward.
Try this before you buy
Save the device instructions and record its current contents before making it part of a routine.
