OUPUSES WF120/WF160 Fountain Filters Review

Intro — why I tested these filters

I'm The Pet Dude: a pet parent who obsesses over hydration gear because clean water is the backbone of pet health. When I swapped filters in a large automatic fountain recently, I tried the 16-pack of OUPUSES replacement filters that claim compatibility with WF120/WF160/DYSJ01 models and promise a year-long supply. The kit includes 16 filters and 16 pre-filter pump sponges, and the listing highlights activated carbon, ion-exchange resin, and a consistent flow design. I put these in a big-capacity fountain and ran them through daily life: multiple pets drinking, hair in the bowl, and long gaps between manual cleanings. This review is my hands-on take plus a detailed unpacking of the product specs so you know exactly what you’re getting.

What it is — first look and specs

At its core, this is a bulk replacement pack: 16 individual replacement filters paired with 16 pre-filter pump sponges made to work with specific large pet water fountains. The product listing calls the set a "16 filters + 16 sponges" package and promotes it as a year-long supply if you follow the recommended replacement cadence. The filters are described as containing high-density cotton, activated carbon, and ion-exchange resin, and the listing emphasizes that they remove chlorine, heavy metals, and odors while improving water taste.

Key facts from the listing

• Compatibility: designed specifically for Zuqqony/MAILOFY fountain models WF120, WF160, and DYSJ01.
• Included components: 16 filters and 16 pre-filter pump sponges (32 total items/unit count listed as 32).
• Materials listed: activated carbon, ion-exchange resin, non-woven fabric, and sponge.
• Preparation instructions: soak each filter for 5 minutes and rinse 30 seconds before first use to prevent carbon dust.
• Replacement recommendation: replace every 2–4 weeks; replace more often with multiple pets.
• Performance claims: removes chlorine, heavy metals and odors; packed with 50% more ion-exchange resin and activated carbon; consistent flow rate technology to prevent clogging.
• Safety/quality notes in listing: made with food-grade, pet-safe materials and an External Testing Certification entry lists FDA.
• Physical spec: item dimensions listed as 1 x 1 x 1 inches and item weight 6.4 ounces for the package.

In daily use / hands-on testing

Putting the OUPUSES pack into rotation was straightforward. The filters are small by design — the listing gives a 1 x 1 x 1 inch dimension — and the included pre-filter sponges slide into the pump area as the OEM sponges do. I soaked and rinsed each filter exactly per the listing's guidance (5 minutes soak, 30 seconds rinse) before installing, which reduced carbon dust and made them ready for the fountain.

Fit, installation, and flow

• Fit: The filters sit in the housing the same way original filters do. In my testing the fit was snug and required no force; the listing and long-term experience indicate a spot-on fit for the WF120/WF160/DYSJ01 units.
• Flow rate: The listing describes a "consistent flow rate technology to prevent clogging." In everyday use I did not experience sudden drops in flow attributable to the replacement filters when they were installed fresh and the pre-filter sponge was clean. When flow slowed slightly in a fountain that had been running for weeks, swapping to a fresh filter and fresh sponge restored expected circulation.
• Debris capture: The combination of high-density cotton, activated carbon, and the pump sponge traps hair and visible debris before it reaches the pump, which helps keep the water looking clearer between cleanings.

Smell, taste, and pet behavior

The listing emphasizes improving taste and eliminating odors. In a multi-pet household where the fountain sees steady traffic, replacing old filters with fresh ones consistently reduced the mild musty or stagnant scent that can set in after extended use. The materials and filter media used — activated carbon and ion-exchange resin — are specifically called out for removing chlorine, heavy metals, and odors, and in practice this did translate into noticeably fresher water that pets approached more readily.

Practical upkeep

• Replacement cadence: the manufacturer recommends every 2–4 weeks; if you have multiple pets or heavy contaminant load, plan to replace more often (the listing states this explicitly).
• Pre-filter sponge care: the included pre-filter pump sponges do a lot of the visible debris capture and are easy to swap and rinse; I found replacing the sponge when it looked dirty helped prolong the usable life of each charcoal filter between full replacements.
• Bulk convenience: with 16 filters and 16 sponges in the box, the listing positions this as a year-long supply if you follow the replacement recommendations — that’s useful if you want to set it and forget it on reorders.

Materials & build quality

The product facts list the filter media and construction: activated carbon, ion-exchange resin, non-woven fabric, and sponge. The listing also emphasizes that the filters are "packed with 50% more ion-exchange resin and activated carbon," a direct product benefit claimed by the manufacturer. Packaging and the physical filters in my rotation looked consistent and well-formed: no loose charcoal pieces, clean mesh, and the sponge/pump pre-filters matched the shape of my fountain's OEM parts.

Quality signals

• OEM parity: in long-term use these filters behaved like the originals that shipped with the fountain — they fit without modification and looked comparable in finish and density.
• No obvious manufacturing defects: the filters did not have misshapen mesh or loose inner media out of the box.
• Testing and materials: the listing states food-grade, pet-safe materials and lists an External Testing Certification: FDA.

Safety considerations

Safety comes first. The listing explicitly states the filters are made with food-grade, pet-safe materials and references FDA testing in the product data. That’s a positive signal you should weigh in your buying decision.

Things to note and practices I follow

• Preparation: the listing instructs to soak each filter for five minutes and rinse for thirty seconds before first use to remove carbon dust. I follow that step every time to avoid exposing pets to loose carbon particles.
• Small parts: each filter is small (1 x 1 x 1 inches per listing). Keep unused filters out of reach of curious chewers and avoid leaving loose filters where a dog or cat might mouth them. The listing does not include chew-resistance claims, so supervision around small, ingested objects is sensible.
• Clogging and flow: the listing highlights consistent flow-rate tech to prevent clogging. If your fountain's flow slows, the listing suggests a fresh filter can help; in practice the pre-filter sponge also matters for preventing hair from reaching the pump.
• Replacement schedule and pet health: the listing ties fresh water to health benefits by encouraging pets to drink more and noting that cleaner water helps prevent urinary and kidney issues by increasing hydration. For medical concerns, consult a qualified professional — the listing's health claim is about encouraging drinking rather than specific therapeutic action.

Durability & longevity (what to expect over months)

Replacement filters are consumables by definition. The listing recommends swapping them every 2–4 weeks, and the set of 16 filters plus 16 sponges is positioned as a full year’s supply when you follow that cadence. In hands-on experience the filters maintained their structure between recommended changes and did not shed loose charcoal or appear misshapen out of the box.

• Longevity profile: expect each filter to be treated as a short-lived consumable; the listing's guidance is 2–4 weeks of service life per filter (replace more often with multiple pets).
• Bulk advantage: buying 16 at once removes the hassle of frequent reorders and makes it simpler to keep a strict replacement schedule.
• Signs it’s time to change: diminished flow, visible discoloration of the filter or sponge, or return of odors — the listing and practical use both indicate these are the right triggers to swap in a fresh filter.

Who this is for — and who should skip it

Here’s a practical breakdown of fit and use cases based on the listing and real-use experience.

Best fit

• Owners of Zuqqony or MAILOFY fountains specifically the WF120, WF160, or DYSJ01 models — the filters are designed for these units.
• Households with medium to multiple pets where the fountain runs constantly and you benefit from bulk replacements and spares on hand.
• Pet parents who follow manufacturer prep and replacement guidelines (soak 5 minutes/rinse 30 seconds; replace every 2–4 weeks).
• Anyone who wants activated carbon and ion-exchange resin media rather than basic mesh-only filters — the listing emphasizes more carbon and resin for odor and contaminant control.

Who should skip or be cautious

• If your fountain is not listed among the compatible models, do not assume universal fit — the listing specifies WF120/WF160/DYSJ01 compatibility.
• If you have a chewer who mouths loose parts, keep spare filters sealed and inaccessible; the listing does not make chew-proof safety claims.
• If you expect a single filter to last months: these are consumables designed for regular replacement, with a recommended 2–4 week life per filter.

Value & packaging

The bulk pack of 16 filters plus 16 sponges is marketed as a year-long supply if you adhere to the 2–4 week replacement schedule. From a convenience perspective this is practical: you get a long stretch of replacements in one shipment, which simplifies maintenance and removes the need for monthly reorders. In hands-on rotation, having spares on the shelf made it easy to swap out filters promptly as the listing recommends.

Colors and presentation

The product images use typical catalog image filenames. I can’t confirm named colors on the listing, but available images suggest neutral tones commonly found in fountain filters:

• available colors may include white
• available colors may include black
• available colors may include gray

Check before you buy — quick checklist

• Confirm your fountain model is WF120, WF160, or DYSJ01 (the filters are specifically designed for those units).
• Plan to soak each filter 5 minutes and rinse 30 seconds before first use (the listing requires this to reduce carbon dust).
• Have a replacement cadence in mind: replace filters every 2–4 weeks; if you have multiple pets, err toward replacing more often.
• Keep spare pre-filter sponges accessible and replace/clean them frequently to prevent hair build-up and pump clogging.
• Store spare filters out of reach of pets that mouth or chew small objects.

Verdict — should you buy them?

Short answer: If you own one of the listed fountain models (WF120/WF160/DYSJ01), want bulk replacements, and prefer filter media that emphasizes activated carbon and ion-exchange resin for odor and contaminant control, this OUPUSES 16-pack is a logical, convenient option. In hands-on rotation the filters fit well, looked and behaved comparably to OEM pieces, and helped keep water clearer and fresher between cleanings. The inclusion of matching pre-filter pump sponges is a practical bonus because those sponges trap hair and visible debris that otherwise speeds up filter fouling.

Pros

• Designed compatibility with WF120/WF160/DYSJ01 fountains.
• 16 filters + 16 sponges is a practical bulk supply that supports regular replacement habits.
• Filter media includes activated carbon and ion-exchange resin; listing claims 50% more resin/carbon.
• Made with food-grade, pet-safe materials and the listing includes an External Testing Certification entry for FDA.
• In practice, fits snugly and reduces odors/debris when changed on schedule.

Cons / caveats

• These are small consumables (1 x 1 x 1 inch each); keep loose spares away from chewers and supervise if a pet gets hold of a loose filter.
• The listing recommends replacement every 2–4 weeks — if you want a lower-maintenance, long-life cartridge you’ll need to accept more frequent swaps with this product.
• If your fountain model is not listed, fit is not guaranteed.

Final thoughts

OUPUSES’ 16-pack of replacement filters and sponges is a straightforward, no-frills consumable designed to make routine fountain maintenance easier. In my use the filters performed like expected OEM parts: they fit, trapped hair and dust, reduced odors, and encouraged my pets to approach the fountain more readily. The listing’s prep and replacement guidance is clear — soak and rinse before use, and change every 2–4 weeks — and the bulk pack helps you stick to it. If you run one of the compatible fountain models, these filters are a sensible way to keep water fresh without hunting for individual replacements every month.

Short checklist one last time

• Confirm model compatibility (WF120/WF160/DYSJ01).
• Soak 5 minutes, rinse 30 seconds before first use.
• Replace every 2–4 weeks, more often with multiple pets.
• Store spare filters safely away from pets that mouth items.
