Easy setup and connects easily for me, though I am always within 20 feet.

These things are awesome. But if it’s priced anything over 30$ your better off just buying a hole new unit that comes with the filter.

I bought the studor doodads for my stink pipe. This is the filter that goes in it. It works wonderfully. Before we had this the odor from the septic would be omnipresent. With this we have been in the clear for over 2 years. Only problem is the filters are hard to find. Update: filter still hard to find. This price is insane. The whole studor contraption is cheaper than the filter.

Make sure it will fit your pipe, and that your pipe will allow removal and replacement of whatever cap is covering it as it leaves the ground. But if you have those covered, this will radically reduce odors, down to zero. For me, they have consistently lasted 18 – 24 months before beginning to pass some (very minor) odor again.
