Spray booth exhaust filters
Paint Pocket vs EU3 Fibreglass Exhaust Filter
If you want the fast answer, pick Paint Pocket when you are dealing with heavier overspray and you want longer change intervals. Pick EU3 fibreglass when you want a dependable everyday exhaust filter at a lower upfront cost.
Quick comparison table
| What matters | Paint Pocket | EU3 fibreglass | Winner |
|---|---|---|---|
| Best for | High throughput booths, heavier overspray, fewer changeouts, steady performance | Everyday booths, moderate usage, simple routine, lower upfront cost | Depends |
| Overspray holding | Very high holding capacity, pockets load slower before airflow starts dropping | Good capture, tends to load faster under heavier overspray | Paint Pocket |
| Airflow stability | Typically steadier deeper into its service life | Stable early, can rise in resistance sooner in heavy use | Paint Pocket |
| Upfront cost | Higher | Lower | EU3 |
| Cost over time | Often cheaper per week in busy booths because you change it less | Excellent value when usage is moderate and change intervals are already healthy | Depends |
| Typical change interval | Often longer in heavier overspray environments | Often shorter in heavier overspray environments | Paint Pocket |
| Best quick pick | If you want fewer changeouts and more consistent booth performance | If you want a straightforward standard option for everyday work | Depends |
Change frequency depends on booth load, coatings, airflow, and inlet filter condition. The goal is stable airflow and clean capture, not squeezing extra days and risking finish quality.
The honest way professionals choose
Choose Paint Pocket if
- Your booth is busy and you are changing exhaust media too often
- You want more stable airflow deeper into the filter life
- You want fewer changeouts across the month
- You care about reduced downtime and less cleaning pain
Choose EU3 fibreglass if
- You want a reliable standard exhaust filter that gets the job done
- Your booth usage is moderate and change intervals are already reasonable
- You prefer lower upfront cost and simple replacement
- You want a practical option for everyday spray work
Exhaust media is cheap compared to rework and downtime. If airflow drops, pressure balance feels off, or capture gets messy, change it.
What Paint Pocket is
Paint Pocket exhaust filters use a layered pocket style media designed to trap overspray efficiently while keeping airflow more consistent. Workshops that run higher volume tend to choose Paint Pocket because it can hold more before performance drops.
What EU3 fibreglass is
EU3 fibreglass is a proven exhaust filter media used in many booths as a dependable standard option. It captures overspray well and is widely used because it is straightforward, effective, and cost friendly upfront.
If you have a solid routine and your booth is not getting hammered all day, EU3 can be a very sensible choice.
How often should you change exhaust filters
There is no single schedule that fits every booth. Change frequency depends on workload, coatings, airflow settings, and inlet filter condition. Many workshops land somewhere between a few weeks and a couple of months, but the better rule is performance based.
Simple signs it is time
- Airflow feels weaker or the booth struggles to hold stable pressure
- Visible overspray build up and uneven loading on the media
- More paint mist or mess downstream than normal
- Finish quality issues that line up with booth performance changes
If you are changing exhaust media way more often than you think you should be, check inlet filters and sealing first. A booth that is breathing badly makes everything load faster.
Ready to choose
Want fewer changeouts and steadier performance. Go Paint Pocket. Want a dependable standard option at a lower upfront cost. Go EU3 fibreglass.
FAQs
Which is better, Paint Pocket or EU3 fibreglass
Paint Pocket is usually better for high throughput booths because it holds more overspray and tends to keep airflow steadier over time. EU3 fibreglass is a strong standard option when you want dependable performance and lower upfront cost.
Which exhaust filter lasts longer
In heavier overspray environments, Paint Pocket often lasts longer before performance drops. In moderate use, both can perform well depending on airflow, sealing, and inlet filter maintenance.
Why does my exhaust filter clog faster than expected
Common causes include higher overspray volume, inlet filters that are overdue, poor sealing causing bypass, or airflow settings that are out of balance. If clogging is frequent, a higher holding option like Paint Pocket can help.
How do I install fibreglass media correctly
For fibreglass media, the green side faces the spray area and the white side faces the outlet. Make sure the media sits flat and seals properly so air does not bypass around the edges.
Which one do most workshops choose
Busy workshops that value fewer changeouts often lean toward Paint Pocket. Workshops with moderate usage often stick with EU3 to keep the routine simple and cost effective.
If you are choosing between two sizes, measure the exhaust frame opening and aim for a clean seal with no gaps. If you want, send us a photo of your exhaust section and we will point you in the right direction.
