Quick answer: PETKIT identifies the EverSweet 3 Pro (UVC) as model P4108. Its official US listing gives a 1.6 L capacity, Bluetooth app connection and says the power adapter is not included. PETKIT’s Filter Unit 3.0 page identifies replacement filter P4161 and explicitly lists EverSweet 3 Pro (UVC) as compatible. Check the model and the adapter before ordering the fountain, then match P4161 when replacing the filter. (EverSweet 3 Pro (UVC) official page; PETKIT Filter Unit 3.0 page)

Confirm the P4108 model
Use the exact product name and model code together: PETKIT’s US listing names this fountain EverSweet 3 Pro (UVC), P4108. The same page lists 1.6 L capacity and Bluetooth app connection. Those identifiers help separate the item you are considering from other fountains whose names share “EverSweet” or “3 Pro.” (PETKIT official P4108 listing)
This guide is limited to the US-listed UVC version. It does not compare it with, or make claims about the specifications or US availability of, a separate non-UVC SKU. A similar name is not enough to establish a variant’s existence or feature set. If a listing omits “(UVC)” or the model code, resolve that difference with the seller or PETKIT before relying on the details below.
Check app, pump and power requirements
PETKIT lists Bluetooth for app connection and says the power adapter is not included. Its product overview identifies a wireless UVC pump and Filter 3.0 in the package presentation. The important shopping distinction is that a wireless pump does not mean the fountain is battery-powered: check the official setup instructions and package requirements, and budget for the missing adapter. (PETKIT official P4108 listing)
The manufacturer’s product name includes “UVC,” and its listing describes a UVC pump. This article reports that product designation only; it does not independently verify disinfection performance or claim a health outcome. Treat feature labels as information about what PETKIT lists, and decide whether the rest of the fountain’s documented setup fits your needs.
The 1.6 L capacity is a reservoir size, not a fixed number of days between refills. Water use differs by household and pet. If capacity is a deciding factor, compare the stated volume with your normal refill routine rather than assuming the label predicts a specific duration. (PETKIT official P4108 listing)
Match the replacement filter
PETKIT identifies Filter Unit 3.0 as P4161 and its compatibility list expressly names EverSweet 3 Pro (UVC). The same list also separately names EverSweet 3 Pro, EverSweet Solo 2 and EverSweet Solo SE. This is model-specific evidence for the P4161 filter, not evidence that those fountains are identical or that their other components can be swapped. (PETKIT Filter Unit 3.0 page)
The filter listing suggests a replacement cycle of 2–4 weeks per filter. Treat that as manufacturer guidance rather than a guarantee that every filter lasts a fixed time. Check the package for P4161 and match the supported-model list to the exact fountain name. Do not buy a generic “PETKIT fountain filter” based on brand alone when PETKIT provides a specific filter code. (PETKIT Filter Unit 3.0 page)
Keep related model names separate
| Item | What PETKIT identifies | Buying check |
|---|---|---|
| EverSweet 3 Pro (UVC) fountain | P4108 | Confirm this exact version and code on the product details. |
| Filter Unit 3.0 | P4161 | The official list names P4108’s fountain as compatible. |
| EverSweet 3 Pro | Listed separately from the UVC name on the filter compatibility page. | Shared filter fit does not establish identical fountain specifications. |
| EverSweet Solo 2 / Solo SE | Separately listed supported fountains for P4161. | Their inclusion does not mean their pumps, capacity or features match P4108. |
The table separates product identity from replacement-filter compatibility. PETKIT listing one filter for several fountain names does not establish that the fountains share the same pump, tank, app behavior or other accessories. Verify each component against its own model-specific listing. (PETKIT P4108 listing; Filter Unit 3.0 compatibility page)
Use the buying checklist
- Confirm the version and code. Check that the fountain listing says EverSweet 3 Pro (UVC) and P4108.
- Check the capacity. The US listing specifies 1.6 L; decide if that reservoir size fits your refill routine.
- Plan app setup. PETKIT lists Bluetooth, so review the current app and setup requirements for this exact product.
- Budget for power. The adapter is not included. Confirm the required adapter and cable setup before checkout.
- Match the filter. Look for P4161 and confirm that the current manufacturer compatibility list includes your exact fountain name.
- Keep UVC claims in scope. The product designation describes what PETKIT sells; it is not independent proof of performance or a health benefit.
- Recheck the live listing. Price and checkout stock change, so verify them directly when purchasing; this guide makes no current price or availability claim.
P4108 is the model to verify when you want the US-listed EverSweet 3 Pro (UVC). P4161 is the filter code PETKIT names for that fountain. Confirm both identifiers and the adapter requirement before ordering; do not infer a different version’s specifications from a similar product name.
