No, it is a concentrator. See penultimate bullet point under main heading:
"�¤ ã€�Molecular Sieve Oxygen Generator】 Molecular sieve oxygen generator
is an advanced gas separation technology. The physical method (PSA
method) directly extracts oxygen from the air, which is ready for use,
fresh and natural. No atomization function. "
