Ensuring that the replacement parts of an air purifier are replaced as per the manufacturers instructions is vital to maintaining efficiency and performance.
Both air purifiers that we stock from the Blueair Blue Pure range (411 & 221) advise changing the main filter every six months depending on operating conditions. Please note each pack contains one filter.
The change filter indicator on the machine will turn red when you should change the filter. This is activated 6 months after operation. When the filter has been replaced, in order to reset the filter alert press the button down for a duration of five seconds. Please see the manual for further information.
The change filter indicator will turn yellow after 5 months of operation indicating that it is time to order a new filter. When the indicator turns red (after 1 extra month of operation), the main filter should be changed. To reset the filter alert, press the button for three seconds.
