Compatible Shark HP100UK HP102PET HC450 HC451 HC452 Air Purifier Filter

This replacement filter fits Shark air purifiers across the HC and HP model ranges and is supplied singly.

A purifier filter does its job by loading up. Every particle it captures is one more restriction in the airflow path, so performance falls away gradually rather than failing outright. The machine compensates by running the fan harder, which is why the first sign is usually noise rather than poor air, and a unit sitting on a higher speed setting than it once needed. Filters of this type are not washable unless the handbook specifically says so, as rinsing destroys the media and leaves the machine circulating unfiltered air while appearing to work normally. Switch the unit off at the socket before opening the housing.

Key Features:

• Restore The Purifier To Full Output - A blocked filter is why the unit sits on a higher fan speed than it used to need and still takes longer to clear a room than it did when new
• Noise Is The First Warning - Performance falls away gradually rather than failing outright, so the machine gets louder long before you notice any difference in the air around you
• Worth Doing For Pets And Allergies - A restricted purifier is quietly doing far less than the panel suggests, which undermines the whole reason for running one in the house at all
• Do Not Wash This Filter - Rinsing destroys the media and leaves the machine circulating unfiltered air while looking like it is working. Replace rather than clean unless the handbook says otherwise
