Every Oneisall fountain in our database has its own carbon filter: part 9L24WAZ covers the PW13 and PW14 together, while the 7L, 10L, PW03 and PW04 each have a separate one. The manuals say to change the filter every 15 days. Four models also have a replacement pump listed.

Which Oneisall filter fits which fountain?

Oneisall changed its filter design with each new model, so there is no single "Oneisall filter". The table shows what the maker lists. The finder above covers the same data with check dates and links to the product pages.

Fountain Filter Part code Media Pump part
7L Dog Fountain (PWF-002) 7L Carbon Filters PJ17023 Activated carbon, sponge 9D05WAZ
10L Dog Fountain (PW07) 10L Carbon Filters 9L13WAZ Activated carbon 9D11WAZ
PW03 3.5L Corded 3.5L Corded Carbon Filters 9L17WAZ Activated carbon 9D07WAZ
PW04 3.5L Cordless 3.5L Cordless Carbon Filters 9L14WAZ Activated carbon 9D13WAZ
PW13 2.2L Cordless 2.2L/3.2L Carbon Filters 9L24WAZ Activated carbon, sponge not recorded
PW14 3.2L Cordless 2.2L/3.2L Carbon Filters 9L24WAZ Activated carbon, sponge not recorded

Pack sizes vary between six and eight filters per listing. The PW03 and PW04 filters have different part codes despite the same tank size, so check the cordless or corded label on the listing.

How often should I replace it?

The PW03, PW04, PW07, PW13 and PW14 manuals state every 15 days, which we record as two weeks. The PWF-002 manual is looser: carbon every 2 to 4 weeks and the sponge or foam every 1 to 2 months. The PW04 has a filter reminder light. Fifteen days is short compared with a 30-day filter from some other makers, but the media amounts differ, so do not read it as better or worse. The interval page lays the brands out together.

How do I install an Oneisall filter?

Four panels: unplug and remove the old filter, rinse the new one, fit it, refill and restart
The general replacement sequence; Oneisall manuals show the filter box for each model.
  1. Unplug the fountain, or switch off the cordless module, and lift out the old filter.
  2. Soak the new filter in a separate bowl of clean water for about 5 minutes. Oneisall says not to soak it in the fountain tank.
  3. On the 7L, the manual says to place the filter in its box with the flat side up before refitting the cover.
  4. Refill between MIN and MAX and restart.

Pumps and when to replace one

Oneisall says a fountain pump normally lasts around 1.5 to 2 years, and the 7L and 10L manuals describe cleaning the impeller with a small brush under warm water. Replace the pump if the noise comes back right after a clean. The noisy pump page has the diagnostics, and the pump finder lists parts across brands.

What if my model is not here?

Oneisall also sells other designs not yet in our database. See the manuals link on the Oneisall brand page.

FAQ

Do Oneisall filters fit every Oneisall fountain?

No. The 7L, 10L, PW03 and PW04 each have their own filter part, and one shared part covers PW13 and PW14. Match by model number, which is printed in the manual.

How often should I change an Oneisall filter?

Most manuals say every 15 days. The PWF-002 manual gives 2 to 4 weeks for the carbon filter and 1 to 2 months for the sponge, and the PW13 and PW14 FAQ gives 2 to 4 weeks.

Do I need to soak the new filter?

Yes for the 7L and 10L: soak it in clean water for about 5 minutes first, in a separate bowl rather than in the fountain tank. Fitting a dry filter is a documented cause of water spilling over the filter case.

Can I replace the pump on an Oneisall fountain?

For four models, yes. Oneisall lists replacement pumps for the 7L, 10L, PW03 and PW04. We have no pump recorded for the PW13 and PW14.
