Wine Filter Types: Plate, Cartridge or Crossflow?

Choosing between the main wine filter types is a three-variable decision: what level of clarity you need, how much wine you filter per year, and how much labour and loss you can tolerate. Plate filters are the flexible low-capital option, cartridge filters are the precision final step before bottling, and crossflow filters replace multiple passes with one machine — at a much higher purchase price. This guide gives you a decision path you can take straight into supplier conversations.

First, define the job: clarification, polish, or sterile bottling

Filter choice starts with the outcome, not the machine. Wine filtration jobs fall into three broad levels:

• Rough clarification — taking turbid, post-fermentation or post-fining wine down to "clear to the eye". High solids loading, coarser media.
• Polishing — removing fine haze so the wine is bright and stable-looking in the glass.
• Sterile (membrane) bottling filtration — removing yeast and bacteria immediately before the filler, typically with a final membrane cartridge, to protect bottled wine from refermentation or spoilage.

Most wineries need more than one level across the season, which is why the real question is rarely "which filter is best" but "which combination covers my jobs with the least cost, labour, and wine loss". For a primer on the full category, see our wine filtration equipment guide.

A note on ratings: filter media are described by micron ratings, but a nominal rating (retains most particles of that size) is not the same as an absolute rating (retains effectively all of them). When you compare spec sheets, confirm which one the manufacturer is quoting — it changes what the filter actually does.

Plate-and-frame filters: flexible and low capital

A plate (sheet) filter presses wine through a stack of cellulose-based pads clamped between plates. Changing the pad grade changes the job — the same frame can rough-filter cloudy wine one week and polish another lot the next. A 40-plate unit like the plate filter PF40 or the 40x40 plate-and-frame filter is a typical small-to-mid winery format.

Strengths

• Lowest purchase price of the three types- One frame covers many jobs by swapping pad grades
• Simple, robust, easy to understand and repair
• Handles dirty wine that would blind a cartridge instantly

Limits

• Pads are consumables — recurring cost and changeover labour every run- Wine losses at start-up and in the pads each cycle- Open frames mean more oxygen pickup and drips unless carefully managed
• Throughput drops as pads load; large or very turbid lots may need multiple pad changes

Cartridge filters: precision before the filler

Cartridge filtration runs wine through pleated elements sealed inside a stainless housing, such as the cartridge filter housing 10" or the CFH10 cartridge filter. Cartridges come in graded steps down to final membranes for sterile bottling.

Strengths

• The standard final-guard step at the filler on bottling day

• Enclosed flow path: minimal oxygen pickup and low losses

• Absolute-rated membrane cartridges available for sterile filtration

• Membrane cartridges can be integrity-tested and regenerated across multiple usesLimits

• Cartridges blind quickly on wine that isn't already clean — they are a finishing tool, not a clean-up tool

• Element cost is significant if used as a primary filter- You still need an upstream method (plate, lees handling, or crossflow) to get wine cartridge-ready

In practice, almost every winery that bottles its own wine ends up owning cartridge housings regardless of which primary filter it chooses.

Crossflow filters: one pass, one machine

A crossflow (tangential) filter pumps wine across the surface of a membrane rather than straight through it, so solids stay suspended in the retentate instead of caking the media. The result: cloudy wine in, bright and often bottle-ready wine out, in a single pass, with no consumable pads. Compact units such as the crossflow filter CF500 target smaller wineries, while the crossflow filter CF1000 suits higher annual volumes.

Strengths

• Replaces multiple plate/earth passes with one operation
• Very low wine loss and low oxygen pickup in an enclosed loop- No pad or earth consumables; mostly automated operation
• Frees skilled cellar labour during the busiest months

Limits

• The highest purchase price of the three types — often several times a plate setup- Membranes are a major replacement cost over the machine's life- Needs cleaning chemicals, water, and a disciplined CIP routine
• Below a certain annual volume the capital simply doesn't pay back; many small wineries instead hire mobile crossflow servicesFor a deeper cost-and-labour comparison of the two main contenders, see crossflow vs plate-and-frame filtration, and for a plain-English explainer of the technology, what does a crossflow filter do?

The three wine filter types compared

A simple decision path

1. Bottling sterile-sensitive wines (residual sugar, low SO2, ML-incomplete)? You need membrane cartridge capability at the filler — plan for housings and integrity testing whatever else you buy.
2. Under roughly 50,000 litres a year? A plate filter for clarification plus cartridge housings for bottling covers most jobs at the lowest capital cost. Consider hiring a mobile crossflow for big or difficult lots.
3. Above that volume, or short on cellar labour? Run the numbers on crossflow: count your current pad spend, wine losses, and the cellar hours each filtration run consumes, then compare against quotes.
4. In between? Get quotes for both paths and compare total cost over five years, not just purchase price.

This is buying guidance, not winemaking or engineering advice — validate filtration regimes for your wines with your winemaking team or consultant.

Before you request a quote

Put the same questions to every supplier so the answers line up:

• Throughput on your wine types, not just water-rated flow- Nominal vs absolute ratings of the media quoted
• Consumable costs per 1,000 litres filtered, in writing- Expected wine loss per run and hold-up volume of the machine
• CIP requirements: chemicals, water volume, time
• For crossflow: membrane lifespan assumptions and replacement cost## FAQ

What are the main wine filter types? The three main wine filter types are plate-and-frame (sheet) filters using disposable pads, cartridge filters using pleated elements in stainless housings, and crossflow (tangential) membrane filters. Plate filters clarify and polish, cartridges handle final and sterile filtration, and crossflow does one-pass clarification with no pads.

What micron rating do I need to filter wine? It depends on the job: coarse clarification works at several microns, polishing tighter, and sterile bottling typically uses a 0.45 micron absolute membrane as the final step. Always check whether a quoted rating is nominal or absolute — they behave very differently in practice.

Is a crossflow filter worth it for a small winery? Often not on capital cost alone— small wineries usually get crossflow results by hiring a mobile filtration service and owning only a plate filter and cartridge housings. Crossflow purchase starts to pay back as volumes, labour costs, and pad consumption climb.

Can I bottle wine without filtering it? Yes — some styles are deliberately bottled unfiltered. But wines with residual sugar, incomplete malolactic fermentation, or low sulfite levels carry real refermentation and spoilage risk without sterile filtration. Treat unfiltered bottling as a winemaking decision, not an equipment cost saving.

Bottom line

Define the filtration jobs first, then buy the smallest set of equipment that covers them: a plate filter plus cartridge housings is the classic small-winery answer, while crossflow rewards volume and replaces labour and consumables with capital. Compare five-year costs, not sticker prices — and get every throughput and consumable figure from suppliers in writing.
