Neareal Oval 74oz: problems, parts and running costs

Checked: 2026-10-06

Summary

The Neareal Oval 74oz is a 2.2 L stainless-steel cat fountain that usually goes wrong in two ways: expensive official consumables and biofilm buildup in plastic parts. Following Neareal’s filter replacement schedule literally costs roughly $71–143 per year. At $20 or less it is a good buy for a small cat; above $30 it is hard to justify.

Common problems and fixes

Expensive official consumables — Neareal recommends replacing the filter and sponge every 1–2 weeks; its 12-pack is $32.99, so following that schedule literally costs roughly $71–143 per year. Workaround: rinse weekly and replace by condition, as owners of related Neareal fountains describe. [1] [6]
Biofilm and mold in plastic/silicone crevices — family-level Neareal reports flag biofilm or mold in small plastic and silicone parts; continuous fountains require frequent physical cleaning regardless of filtration. [7] [8]
Pump failures and clogging — reported in 108 oz and VB-01 discussions; no exact-model replacement pump is sold separately, so pump repairs are unclear. [7] [8]
Unverified performance claims — ≤28 dB pump noise, seven-day water capacity and filtration effectiveness are manufacturer claims, not independently measured. [1] [4]
Revision mapping unresolved — the exact listing is documented as Oval/Oval Mini, while Neareal’s current page calls its 74 oz fountain Oval Duo and describes upgrades; the exact listing’s relationship to the current page is not proven. [1] [4]
Conflicting dimensions — the spec table gives 8.07 × 5.9 × 6.89 in, while a graphic shows 7.87 × 5.31 × 7.48 in including the spout. [4]

Parts and consumables

Replacement filter (triple-layer: non-woven fabric, ion-exchange resin, activated carbon) — 6-pack $22.99 or 12-pack $32.99 from Neareal direct; replace every 1–2 weeks per Neareal. [1] [2] [3]
Pre-filter sponge — sold alongside filters in Neareal’s packs; replace on the same 1–2 week interval. [1] [2] [3]
Pump (5 V) — no exact-model replacement pump listing was found; pump repairability is unclear. [1] [4]
Power adapter — included with the fountain. [1]
Cleaning brush — mentioned in exact-listing documentation. [4]

Yearly running cost

At Neareal’s official 1–2 week replacement interval, the 12-pack at $32.99 covers roughly 12–24 weeks, so annual filter spend is roughly $71–143. This excludes electricity and cleaning supplies. Owners who rinse weekly and replace by condition spend less, but that is not Neareal’s official schedule.

When it is a good buy

Price thresholds from the September 2026 research pass:

$20 or less — excellent hardware value: stainless steel, visible water level, low-voltage pump. [1]
$20–25 — good, still competitive for stainless steel. [1]
$25–30 — average; larger 95–108 oz alternatives become more attractive. [1]
Above $30 — weak for the 74 oz base fountain unless extra filters or accessories are included. [1]

Alternative: the Veken C1 stainless 108 oz at around $27.99 is a better choice when you want more capacity. [1]
