Immuune Grey-Water Filtration and Disposal Systems
Immuune is our own range of caravan and motorhome grey-water filtration and disposal products. The systems are designed for suitable wastewater from caravan and motorhome sinks and showers, filtering it before responsible disposal.
Filtered grey water may be released to the ground only where campsite rules and local requirements permit. If ground discharge is not expressly allowed, collect the wastewater and use the campsite’s approved disposal point.

What Immuune does
Immuune provides a practical route for managing suitable caravan or motorhome grey water. Wastewater passes through the system’s internal Japanese matting fish-pond filter material before disposal. The filtering material should not be described as foam.
Immuune is for grey water or suitable wastewater only. It is not designed for toilet waste or black water, and it is not a fresh-water or drinking-water purifier. It does not make wastewater safe to drink.
Who it is for
The range is intended for caravan and motorhome owners who need a clearer way to manage suitable sink and shower wastewater on touring or seasonal pitches. It may support off-grid water planning, but it does not replace site rules, designated disposal points or good wastewater hygiene.
Caravan and motorhome options
Caravan and motorhome layouts use different waste-outlet arrangements, so separate product versions are available where applicable:
- Caravan version: the twin-pipe option shown on the verified Etsy listing is designed for caravan waste outlets.
- Motorhome version: the single-pipe option shown on the verified Etsy listing is designed for motorhome waste outlets.
Check the current marketplace listing and your vehicle’s outlet arrangement before ordering. A caravan product should not be assumed to fit a motorhome, or vice versa.
Choose the right Immuune product
| Product option | Designed for | What to check | Ordering route |
|---|---|---|---|
| Caravan twin-pipe system | Caravans with the matching twin waste-outlet arrangement | Outlet spacing, hose route and the components included with the selected listing | View caravan option |
| Motorhome single-pipe system | Motorhomes with a compatible single grey-water outlet | Outlet diameter, connection arrangement and permitted disposal location | View motorhome option |
| Replacement internal filter | Existing Immuune owners replacing used filtering material | Compatibility with the owned system and current replacement instructions | Check replacement filters |
| Additional hose length | Touring pitches where extra reach is needed | Required length, correct connection and safe routing without trip hazards | Check hose options |
Before ordering: identify whether your vehicle has a caravan-style twin outlet or a motorhome-style single outlet, check the current listing photographs and included components, and confirm how the campsite requires grey water to be disposed of.
How the system works
- Connect the correct caravan or motorhome version to the suitable grey-water outlet.
- Suitable sink and shower wastewater flows through the internal Japanese matting fish-pond filter material.
- Dispose of the filtered water only in the way permitted by the campsite and local requirements.
The system does not create universal permission for ground discharge. Always use an approved disposal point when site rules or local requirements do not expressly permit release to the ground.
What is supplied
The selected Immuune system is supplied assembled and ready to use. Buyers do not have to assemble loose filter sections. Check the chosen product listing for the exact caravan or motorhome configuration included with that option.
Replacement filters and additional hose lengths are separate products. They are not automatically included as free extras unless the current verified listing specifically says otherwise.
Replacement filters
Replacement internal filters are available separately. Replace the internal filtering material in accordance with the product instructions and its condition. Do not assume a spare replacement filter is included with the main system unless the selected listing explicitly includes one.
Hose options
Hose lengths are separate products or options. Choose a hose suitable for the distance between the vehicle outlet, the Immuune system and the permitted disposal location. Check the current listing for availability and exactly what the selected option includes.
Responsible disposal
- Follow campsite instructions and local environmental requirements every time.
- Release filtered grey water to the ground only where this is expressly permitted.
- Use the approved grey-water disposal point whenever ground discharge is not allowed or the rules are unclear.
- Never connect Immuune to toilet waste or black water.
- Keep fresh-water hoses and drinking-water equipment separate from grey-water equipment.
- Do not claim or assume universal legal approval, certification or campsite acceptance.

Important limitations
Immuune filters suitable grey water before responsible disposal. It is not a drinking-water purifier, does not make wastewater potable, does not treat black water and does not guarantee that a campsite or authority will permit ground discharge. The campsite’s instructions and applicable local requirements always take priority.
