The New Nautilus Filter™ OEM model is a perfect fit/direct replacement to replace your Dometic DVF, Sealand, SaniGard, Voker, Yacht Z Marine, Camco and others in this common size format.

Holding Tank Vent Filter - Powered by our refillable Five-Chamber Carbon Helix™ (patent pending), the Nautilus Filter™ OEM has six or more times the air-to-carbon contact time, giving it much extended efficiency in odor removal compared to similar sized conventional holding tank vent filters.

Nautilus Filter™ OEM Model is an great performance upgrade to the common Dometic, Sealand, SaniGard, Voker, Yacht Z Marine, Camco branded models of holding tank vent filters. Unlike these other brands, the Nautilus Filter™ OEM is refillable with the Nautilus Filter™ OEM Activated Carbon Refill Kit. Also, unlike conventional holding tank vent filters.

Please note: The New Nautilus Filter™ OEM is an excellent choice to replace your Dometic DVF, Sealand, SaniGard, Voker, Yacht Z Marine, Camco and others in this common size format, but all of the filters in this OEM conventional size (long and skinny) have a vent airflow restriction compromise - though the Nautilus Filter™ OEM has the least air restriction of any of these conventional OEM format sizes.  If you don't need this exact fit and can fit a Pro model Nautilus Filter™ (slightly shorter and a little larger in diameter) this is the best choice to replace conventional vent filters as it has nearly zero vent restriction unlike these other brands or OEM Model.  If you must have an exact fit replacement to these conventional filters please choose the Nautilus Filter™ OEM model as it is also refillable and has our reverse vent flow bypass valve and less air restriction than the common conventional filters although not as good airflow performance as the  Nautilus Filter™ Pro model.

Nautilus Filter™ OEM Model has a built-in bypass valve to allow free air flow backwards into the holding tank to help prevent tank collapse during aggressive pump outs.

Nautilus Filter™ OEM included 5/8", 3/4", and 3/4" threaded (Dometic fittings) with 316 Stainless Steel Hose Clamps. Other sizes available at no charge - Please contact us to request.
