Abstract: A method and system for noise cancellation in an air purifier is disclosed. The air purifier employed with a noise cancellation system comprises at least one microphone connected to the air purifier. At least one microprocessor programmable and adaptable to operate with a noise cancellation software is connected in a way to receive signals from the microphone placed inside or near the air purifier. A plurality of speakers connected to the microprocessor outputs the noise cancelled sound waves. The system is adaptable to operate with any conventional air purification filters and is capable to achieve optimum effectiveness without generating undesirable noise. The frequency of the noise cancelling sound waves matches the frequency of unwanted sound.
