Replacement Guide
Keep your water pure. Know exactly when and how to replace your filters.
Why Filter Replacement Matters
Your Avida H2O Ultra uses a multi-stage filtration system that captures contaminants over time. As filters reach capacity, their effectiveness decreases — meaning less protection for you and your family.
Replacing filters on schedule ensures you always get 99.9% contaminant removal, great taste, and safe water every day.
Your Filter System
Sediment & Carbon Composite Filter
Removes sediment, chlorine, odor, taste impurities, and large particulates. Your first line of defense.
UF & ACF Composite Filter
Ultrafiltration removes bacteria, viruses, and microorganisms. Activated carbon eliminates remaining chemical contaminants.
100GPD RO Membrane (RO models)
Reverse osmosis membrane removes dissolved solids, heavy metals (lead, arsenic), PFAS, and microplastics at the molecular level.
⚠️ Signs Your Filter Needs Replacing
- Water flow has slowed noticeably
- Water has an unusual taste or odor
- It has been 7+ months since last replacement
- Your dispenser's filter indicator light is on
- You've used more water than usual (high household)
