Awesome

Pretty standard unit I guess but it worked just fine for our sea ray.

Was a direct replacement from a sealand filter, has only been installed for a week but absolutely no smell coming from my vacuflush holding tank vent.

The product was perfect for a replacement as advertised

If you don’t have a black tank vent filter in your boat or RV, you really need to add this activated charcoal filter! It will almost completely eliminate those embarrassing foul odors when you flush. Very inexpensive and simple to add to your system.. and only 2 minutes to change filters every six months or so afterwards..
