To maximize the effectiveness of the Dometic Dust Reduction System, it’s necessary to occasionally replace the DRS Air Filter once it has collected too much dust. The filter is made from water-resistant cardboard and synthetic material resistant to bacteria, mould and odour. Designed to maximize air flow into the caravan while effectively removing dust particles, it keeps the caravan interior fresh. The wire-backing ensures a sturdy construction and a pleated design maximizes dust holding capacity. To replace it, simply open the ceiling cover, squeeze tabs on the filter holder and slide the filter out. Thanks to its compact size, you can conveniently store a spare filter in a drawer or cupboard and ensure an optimum performance from your Dometic Dust Reduction System.
