Filters should be inspected monthly and given a light vacuum to remove dirt and dust. Filters will eventually become blocked with residual debris and should then be replaced. Typically, blocking will occur every 6 – 12 months depending on the location (near busy roads or inner city areas tend to block more quickly than remote country settings).
