Mewra Pure Filter — Mega Pack (36 Filters · 3-Year Supply)
Mewra Pure Filter — Mega Pack (36 Filters · 3-Year Supply)
Three years of fresh, filtered water for your cat. One purchase. Done.
Your Pure Flow fountain is only as healthy as its filter. After 30-60 days, an activated-carbon filter stops cleaning water and starts harboring bacteria. The single most overlooked maintenance step in cat hydration.
This Mega Pack contains 36 activated-carbon filter cartridges — enough for three full years of monthly changes for a single cat, or 18 months in a multi-cat home. The most cost-effective way to never miss a filter change again.
What each filter does
- Activated carbon core — removes chlorine, chloramine, heavy metals, and dissolved odors that subtly discourage drinking
- High-density foam pre-filter — catches hair, dander, and food debris before they reach the pump
- Ion-exchange resin — softens hard water, improves taste
- Non-woven outer layer — final polishing for crystal-clear water
Compatibility
Designed for the Mewra Pure Flow 4L Stainless Steel Fountain and the FEELNEEDY 4L / 135fl oz wireless cat water fountain family.
How often to change
- Single cat: every 30 days → 36 filters = 3 years
- 2-3 cats: every 21 days → ~2 years
- 4+ cats: every 14 days → ~14 months
- Hard tap water: shorten by 25% from the above
3-minute change routine
- Unplug or remove batteries from fountain
- Lift the lid and pump assembly
- Pull out the old filter — discard
- Rinse new filter under cold water for 15 seconds
- Drop it in, reassemble, refill, plug in
Why the Mega Pack is the smart buy
Filter subscriptions in the pet industry show 75-85% annual retention — because the math is small and the convenience is large. Skipping a filter change kills your cat's drinking habit (the water tastes "off" before it does to us). Buying 3 years up front means you literally cannot forget — and you save versus buying smaller packs.
