Loud!
Works ok but is much louder than I expected. Also no way to change or clean the filter that I can see

Dear Customer: Thank you for taking the time to share your feedback. We sincerely apologize that the noise level and filter maintenance did not meet your expectations. To clarify: This oxygen concentrator is designed to operate at around 55 decibels, but we understand that you may still perceive it as louder in a quiet environment. Regarding the filter—clean it periodically, ensuring the air intake is not blocked. We value your feedback and will continuously improve product details to avoid any misunderstandings. Please feel free to contact us if you require any further assistance! Sincerely, Health Beauty Machine customer service team
