Replacement is easy
When it's time to replace your filter (about every six months), start by unplugging your air purifier. Remove the air intake grate on the right-hand side to access the filter. Pull the tabs on either side of the used filter together to close it like a book and remove it. Insert a new filter, opening it like a book inside in the air purifier - the sides should snap into place. Replace the air intake grate and plug it back in. Easy.
