To Vent or Not to Vent: Exploring the Venting Options of the Cuddy Composting Toilet

To Vent or Not to Vent: Exploring the Venting Options of the Cuddy Composting Toilet

 

Hi everyone, Michael from CompoCloset Australia here. 

Today, we're going to have a little chat about the Cuddy composting toilet and the venting options it offers. A common question we hear is: to vent or not to vent? Well, let's delve into that and help you make the best choice for your needs.

The Versatility of Cuddy

As many of you know by now, Cuddy is the most versatile, fully optioned composting toilet in the world. One of its standout features is the ability to customize how you manage airflow and moisture, ensuring optimal performance in various conditions.

Default Setup: Internal Recirculation

When your Cuddy arrives, it comes set up for internal air recirculation. The 12V fan at the back, which draws about 0.2 amps, circulates air through the carbon filter inside the unit. This setup is designed to help manage any excess odors, especially during the initial "shock and awe" period. After that, odors are typically minimal.

Many of our customers are perfectly satisfied with this configuration. The fan quietly does its job, and the carbon filter ensures the air inside the Cuddy stays fresh. However, depending on what's inside the unit and the external temperature, you might notice some moisture buildup or condensation on the inside walls. This is normal and can easily be wiped away with a towel or paper towel.

Going Fan-Free

Interestingly, some users choose not to use the fan at all. They simply set up their Cuddy without the carbon filter and use it as is. The design of the Cuddy allows for this level of flexibility, catering to different preferences and situations.

External Venting: Reducing Excess Moisture

If you're looking to reduce excess moisture and extend the life of your solids bin, venting your Cuddy externally might be a good option. Since approximately 70% of what goes into the Cuddy is moisture, removing it can be beneficial.

Switching to External Venting

One of the most remarkable design features of the Cuddy is how easy it is to switch between internal recirculation and external venting:

  1. Access the Internal Components: Remove the screws holding the housing that contains the carbon filter.

  2. Adjust the Airflow Adapter: Underneath the housing, you'll find a piece that directs the airflow. Simply take it out, turn it over, and place it back into the unit.

  3. Reassemble: Put the screws back on, securing the housing in place.

With these simple steps, the fan will now push air out the back of the unit, enabling external venting.

Venting Options for Different Setups

Portable Use

If you keep your Cuddy portable, you can place it outside your living space occasionally. By connecting it to power and venting externally, you can remove excess moisture effectively. This is especially handy if you've gone a week or two without venting and want to refresh the unit while at a campsite.

Permanent Installations

For those installing the Cuddy permanently in a caravan, camper trailer, or similar setup, you can attach a 22 mm wastewater pipe to the exhaust port at the back of the unit. This allows you to direct the venting outside the vehicle, efficiently managing moisture buildup.

Using Existing Systems

If you already have a SOG system installed, you can connect the SOG pipe directly to the Cuddy. Just remember to disconnect the SOG fan and let the Cuddy's fan handle the external venting.

Keeping Bugs at Bay

When venting externally, it's important to prevent insects from entering the unit:

  • Long Pipes: If you're using an extended pipe for venting, consider placing an old stocking or similar mesh material over the end to act as a barrier.

  • Direct Venting: For setups venting directly to the atmosphere, we offer a specially designed midge mesh fly screen available on our website. It fits perfectly under the airflow adapter, ensuring bugs stay out while air flows freely.

The Choice is Yours

Ultimately, whether you choose to vent your Cuddy externally, recirculate the air internally, or not use the fan at all, the Cuddy gives you the flexibility to decide what's best for you. Its versatile design accommodates a range of preferences and needs, reaffirming why it's the most versatile, fully optioned composting toilet in the world.


We hope this guide helps you understand the venting options available with your Cuddy composting toilet. Remember, the key is flexibility. You can experiment with different setups to see what works best for your situation. If you have any questions or need further assistance, feel free to reach out to us.

Happy composting!

    It sure would be great if Cuddy had a vent kit including pipe or flexible tubing options, a hose clamp, and a port to install in a wall to vent to the exterior.
