The filter frustration we’ve all felt
You finally remember to order that new set of filters. They arrive. And then... they don’t fit. Sound familiar?
Whether it’s the wrong size, the wrong material, or the wrong type entirely, buying commercial kitchen filters online can feel like a guessing game. But it doesn’t have to be.
Here’s how to get it right every time.
Why getting the right filter matters
Filters aren’t just there to stop grease from hitting your fans. The right filter:
- Reduces fire risk
- Improves kitchen airflow
- Keeps extraction systems efficient
- Supports hygiene and compliance
The wrong filter? It might trap nothing, fall out of place, or slow your whole extraction system down.
Understanding your options
There are a few key types of kitchen filters:
Baffle Grease Filters
Standard for most commercial hoods. Can be found in stainless steel or aluminium and are often easy to remove and clean.
Mesh Filters
Lightweight, but less durable. Often used in lighter-duty systems.
Carbon Filters
Great for odour control, usually used with recirculating systems.
HEPA & Panel Filters
Found more in cleanroom or specialist environments.
Knowing what your kitchen needs is step one.
How to measure a filter correctly
Don’t guess. Here’s how to measure:
1. Width (side-to-side)
2. Height (top-to-bottom)
3. Depth (thickness)
Most filters are listed in inches or millimetres. Be consistent and double-check. Still not sure? Take a photo and send it to us, we help kitchens identify the right match every day.
Signs you’re using the wrong filter
- Unusual smoke or odour in the kitchen
- Grease buildup on walls and ceilings
- Extraction fan struggling
- Filters warping or rattling during use

Ordering through us means:
- Quick support from real humans who understand commercial kitchens.
- Guided product matching.

We don’t just sell filters. We help you solve filter problems.
A large school catering kitchen recently told us they used to keep "guessing sizes" and ordering backups “just in case.”
Since switching to Just Filters, they now have the right filter sizes saved in their account, a reorder reminder every three months, and zero wasted purchases.
Want to take it a step further? Many clients sign up to our filter exchange service, which means we'll provide you with a free replacement filter set, so when we collect the used ones we install the spare filter set, so we can take away the dirty ones and clean them professionally, ready for the next exchange date. That way, you're always running with clean filters without having to stop and scrub.
