Bottled & Drinking Water Filtration
Filter Cartridges for Bottled Water & Drinking Water Plants
Clean, clear, safe water at every stage — from source to fill
EcoFiltrone builds food-grade filter cartridges for bottled water, mineral water and drinking water bottling lines. Sediment, carbon and final filtration in true drop-in sizes, at factory-direct prices with free samples before you order.
✔Food-grade & FDA-compliant ✔Sediment to sub-micron ✔ High flow, low footprint
A bottling line is only as clean as its weakest filter. Getting the filtration stages and micron ratings right protects your product, your equipment and your brand — without over-spending on cartridges. Here is how the stages fit together and what to run at each one.
Filtration stages in a water bottling line
Whether you bottle spring, mineral, purified or RO water, the filtration train follows the same logic: remove the coarse solids first, protect the sensitive equipment in the middle, and polish to the final quality just before filling. Skipping a stage doesn’t save money — it just moves the cost downstream to blocked membranes, off-taste or rejected batches.
- Pre-filtration — sand, rust, scale and coarse sediment from the incoming source
- Carbon polishing — chlorine, taste and odor before sensitive stages
- RO / membrane protection — fine pre-filtration to extend membrane life
- Final filtration — a defined sub-micron cut just before the filler
Pre-filtration & sediment removal
Incoming water — from a borehole, municipal supply or storage tank — carries sand, silt, rust and scale. A depth or high-flow cartridge at 5–20 µm protects everything downstream and stops your finer, more expensive filters from blinding off in days. For lines with heavy solids, a filter bag ahead of the cartridge stage lowers the overall cost per litre.
Carbon & taste/odor polishing
Chlorine and chloramine damage RO membranes and leave a taste customers notice. A carbon block or carbon-impregnated cartridge removes them, along with many organic off-flavors, before the water reaches the membrane or the filler. This stage matters most for municipal-source and purified-water products.
RO & membrane protection
If your line uses reverse osmosis, the cartridge directly ahead of the membrane is doing protective, not decorative, work. A 1–5 µm pre-filter keeps particulates off the membrane surface, holds down the SDI and buys you months of extra membrane life. For seawater or high-fouling sources, see our seawater desalination pre-filtration approach.
Final / sub-micron filtration before filling
The last cartridge before the filler sets the microbiological and clarity standard of the bottled product. Pleated cartridges at 0.2–1 µm give a defined, validatable cut. For sterile-grade bottling, an integrity-testable membrane is used — covered on our final & sterile filtration page.
Recommended micron ratings by stage
Use this as a starting point. The right cut depends on your source water and product spec — send us a water analysis and we’ll confirm.
| Stage | Typical micron | Product type | Job |
|---|---|---|---|
| Bulk / heavy solids | 25–50 μm | Filter bag | Protect cartridges, lower cost |
| Pre-filtration | 5–20 μm | Depth / high flow | Sand, rust, scale, silt |
| Carbon polishing | 5–10 μm | Carbon cartridge | Chlorine, taste, odor |
| RO membrane protection | 1–5 μm | Pleated / high flow | Lower SDI, extend membrane |
| Final before filler | 0.2–1 μm | Pleated / membrane | Clarity & microbial cut |

Frequently asked questions
Use this as a starting point. The right cut depends on your source water and product spec — send us a water analysis and we’ll confirm.
What micron filter do I need for bottled water?
It depends on the stage. Pre-filtration is typically 5–20 µm, RO protection 1–5 µm, and final filtration before filling 0.2–1 µm. Send us your source water and product spec and we’ll recommend a full train.
Are your cartridges food-grade and FDA-compliant?
Yes. Our bottled-water media and hardware use materials compliant with recognized food-contact standards
Can you match my existing housing?
In most cases, yes. Our cartridges are built to standard drop-in dimensions, and we build to spec for imported or custom housings. Send us your current model number.
Do you offer free samples?
Yes — we provide free samples so you can fit-test and validate performance on your own line before placing a bulk order.
