A spare pre-filter is the sort of quiet household purchase that proves its worth on laundry day, after cooking, or when a room feels a little stale. This Blueair Genuine Pre-Filter for the Blue Pure 511i Max Air Purifier has a soft, lightly textured washable fabric in Sand, giving the unit a calmer look for bedrooms, rented flats and open-plan corners across the United Kingdom. It is not the showiest upgrade, and the pale shade may need more regular rinsing, but it feels practical, neat and easy to live with.
