Loved my AirHead but it went when I sold the boat (Flicka20). The new boat (Baba30) has an electric TMC and I hate it so I will be switching again. Here's some points you missed... you may not need the fan vent at all. You can try it first without and then decide. If you have to run the fan vent, you do not need to run it all the way to the outside of the boat, there's no harm or weird smells if you run the exhaust to the inside of a lazzarette or an anchor locker. When you dump the compost, it's best to lay out a double trash bag on the floor and then flip it and shake it out. The first time we used Coconut Coir, it didn't compost. The second time we used it, we poured the packet of enzyme starter and then it was fine. The liquids tank does have to be emptied frequently and keep an eye on the fill window in front, we overflowed two time and had to clean up. Lastly the AirHead is one of the tallest compost heads, best to measure your compartment to make sure you'll fit well. Great videos, thanks.

Great video. Thank you!

I have watched all your videos (most of them twice) as part of my prep for my Sail Canada Basic Cruising Exam. The exam was today and I did well. So, I wanted to thank you again for the content that helped me ace my exam and solidify my basic knowledge. I look forward to watching all your future videos and would absolutely love to take a lesson from you if I'm ever in BC. I do quite enjoy these product reviews as well, even though I don't (yet?) have my own boat.

I have the Air head for a year now. Buy compressed coco bricks (avoiding bugs) and use very little water to soak the dry coco, expanding it. I use two coffe cups of water, about 32 oz.per half brick of coco.I buy a case of flat bricks and use half a brick. Bricks are about 10”/ 2”thick. If you use to much water this will bog the coco and make for moldy poor. I change coco every 10 days. Use pine sole water mixture 5-1 ratio to spray the toilet or funnel after using and then you clean every 10 days. I tied a T into the pee outlet, I use sink water which flushes down a 3/4” hose through the t and back into the sink drain hose , and down a though hole. This flushing along with the pine keeps the pee smell out and you don’t have to keep emptying a pee bucket. I have another t installed after the toilet with a funnel I pee into so I don’t have to sit down and pee. Keep the line flowing downhill like a sewer so the pee solids don’t build up. Close the valve when heavy sailing, I love being able to clean my toiled whenever I want not relying on a pump station. Buy coco grow bricks cheap on Amazon. Follow these instructions and you won’t be disappointed! Cheers!

Love the AirHead, have used it for 3 years now, no smell, easy care, no parts to worry about! Just make sure I stir it daily (with the side handle). A bit expensive but worth not having the hassle and smell. Thanks for your great video

Have been using a Nature Head and would NEVER go back to a pump toilet, plus I can move it between the boat and camper with ease. Never installed the fan and never had a smell or bugs to think it was needed. The area where the holding tank had been could hold a year's supply of peat moss. A three day weekend with two of us results in about 2/3-3/4 filling the urine tank, which is then dumped in a marina toilet and rinsed. I throw a splash of vinegar in before re-installing. To not fill the solids tank with toilet paper and minimize the need to empty the tank we use disposable doggy bags. Before pooping we place a cheapo automatic coffee filter over the trap door and it works GREAT. Open the trap door when done, rotate the crank, and you only do a quick wipe of the bowl with vinegar on toilet paper, rather than needing to extensively clean a brown mess. The use of filters hasn't made a difference in how long we go between emptying the solids tank.

I love my Airhead!

I had a Nature’s Head when I lived on my sailboat. Moved back to land and sold the boat. Back on a boat…now a powerboat. My husband just finished removing the entire vacu-flush head system from our boat today. I can’t believe how janky the marine pump system is. I can’t stand the smell exhausting from the white lines, which they claim never smell or fail. BS. Once the last line was removed from the boat, the smell was gone! We can’t fit a NH in the boat, so we had to go with an Airhead. It isn’t made as well as a NH, but it will do. Your video is very helpful to us for our installation. Thanks!

Excellent job explaining the compost head thank you

we have one and has worked out great! this is a nice (and PG) overview of the function and install!!! Thanks Captain Marco!!

Installed an airhead in the forward head about a year and a half ago. Still have marine head in aft. Airhead is the preferred go to for first mate (female) and myself (male). Will replace aft head with another Airhead soon. A couple of things we have learned: Freeze the medium (we use coir bricks) for a few days to kill any insect larvae that might be present. We haven't had any insect problems. Instruct guests to always be sure to close the trapdoor prior to cranking. Some will crank so vigorously that the medium will be flung into the bowl, causing the screen to the liquids tank to become blocked.

I suggest getting an extra P tank. I have one extra and may get a 3rd one day. I'm in Chicago in a slip. I've had mine about 3 years now. I still haven't installed the fan. I got an extra screen for the 2nd hole. Maybe one day I'll install the fan.

I have one ready to install. Just need a boat now 🙂

That was great, thanks for taking the time. I'm guessing you could just dump everything overboard on a passage? Minus any plastic of coarse

Thinking of installing a music box on the side, any requests? Pop goes the weasel!

Thank you for another useful video. Replacing a traditional marine head with a composting head seems to have many advantages.

Great instructional video for the Airhead composting toilet. Just about to buy one but am still hesitant. As pointed out the pros seem to outweigh the cons but still not sure if it’s the right fit for my Van conversion we’re building. One thing I don’t see people mentioning much is what to do with the toilet paper. I hear some say that they put it in a separate garbage container but this is not absolutely necessary. I assume if you put the TP into the toilet it will fill the solids container much more quickly? Can two people using this toilet everyday go a month between emptying and recharging the composting matrix if they put the TP into the toilet? If I had to dispose of the TP separately that would be a no-go, or if I had to dump every couple weeks because it filled too quickly.

It would be neat if someone came up with a hand pump attachment with a quick disconnect for the liquid container. Something that could reattach to the thru hull making liquid management easier…

I spoke to a coast guard officer at a marine show in Florida yesterday. I have an airhead for 6 months now and love it. I asked the officer what the coast guard thought of composting toilets, but he did not know current rules regarding not having a standard pump out but would look into it and get back to me. Do you know how legal composting toilets are?

Does anyone just divert the liquids to the holding tank? It would seem that a 40 gallon black tank with a whole lot of PEe. Don’t know about the smell?

What’s the holding capacity for each section? You said you bag #2 to dispose of it, but where do you dump #1? Thanks.

Just wondering if it would work on a boat that you don’t live on (wouldn’t be turning it daily). Thanks for sharing!

was this the marine seat version or the standard house seat of the airhead ? do you know what the difference is, thank you for the fantastic video

curious if you have the 1 or 2 gallon liquids tank? thanks

What system does the sink drain into? Does it still need a holding tank and pump?

Have you had any problems with a reddish mold growing on the outside of the toilet?
