BWT PK Turbo Filter Bag Guide: Fine, Standard & Cartridge Options
Share
Looking for a replacement bag? The full range, OEM part-code cross-reference and fitment detail live on our BWT PK Turbo replacement filter bags page. This guide covers the background: how the PK Turbo's three filter types differ and which micron to choose.
If your BWT PK Turbo's filter bag is torn, stretched, lost its drawcord or just worn out, you don't have to hunt down the original part or wait on overseas shipping. Our Australian debris bag range fits the PK Turbo (EV105TURBO) — from $44.95, with more micron choices than the bags the unit shipped with.
Quick answer: yes, our bags fit the PK Turbo
The BWT PK Turbo uses the 13″ spa-width bag opening — the same size as The Bottom Feeder and the Kokido Vektro-style cordless cleaners. Every bag in our range is that 13″ spa-width size, so they mount on the PK Turbo the same way the originals do: slide the bag over the head and cinch the drawcord tight.
The larger 15″ professional machines — Hammerhead, Riptide, Power Vac — commonly use a wider bag, so we don't advertise our 13″ bags for those machines.
Which micron should you choose?
The PK Turbo ships with a standard bag (leaves and twigs) and a fine bag (sand and grass). The commonly published rating for that OEM fine bag is 75 µm, and for the standard bag 250 µm — though grade names and ratings do vary between BWT documents and model years, so check what's printed on your own bag. Replacing a worn bag is also the perfect moment to match the mesh to what's actually in your pool:
| If your pool has… | Choose | Why |
|---|---|---|
| Fine dust, dead algae, silt | 40 micron extra-long or 57 micron | Both have a smaller nominal opening than the PK Turbo's 75 µm stock fine bag, so they hold back material a stock fine bag lets through |
| Sand and fine silt — a like-for-like fine bag | 80 micron | Our closest nominal micron match to a 75 µm OEM fine bag. To be straight with you: 80 µm is very slightly more open than 75 µm, not finer — it's the like-for-like replacement, and 57 µm is the step up in tightness |
| Sand and general grit | 100 micron | Fine capture with faster flow — the everyday service choice |
| Leaves, twigs, pebbles | 140 micron | The general-purpose leaf bag. Tighter than a 250 µm standard bag rather than an equivalent grade to it |
| Storm debris, autumn leaf fall | 180 micron coarse or Green 3 mm heavy-duty | Maximum flow for big clean-ups without clogging. The 3 mm bag is a leaf catcher, not a filter — 3 mm is 3,000 µm |

A note on grade names
"Standard", "regular", "fine" and "coarse" are not standardised across brands. The pairing most PK Turbo and Kokido owners are replacing is a 250 µm standard and a 75 µm fine, but other suppliers use the same words for very different numbers. Where you can find a published micron rating for your own bag, go by that number rather than the grade name.
One honest note: mesh bags vs the cartridge filter
The PK Turbo's kit also includes a pleated cartridge filter for very fine silt. Our range replaces the mesh bags (standard and fine), not the pleated cartridge. That said, the 40 and 57 micron mesh bags cover most of the fine-debris work the cartridge is used for — with more capacity and easier rinsing between jobs.
Also fits Kokido — and a caveat on the BWT F1 Turbo
The same 13″ spa-width bags fit Kokido drawcord bag cleaners in the Vektro family. Full detail, part numbers and the honest measure-first list is on our Kokido replacement filter bags page.
The BWT F1 Turbo is a closer call than it looks. BWT documents its filter-bag attachment as a Click N' Lock system, and a click-lock mount is a different mechanism from a drawcord bag — so opening width alone doesn't settle compatibility. If you run an F1 Turbo, send us your model and we'll confirm before you order rather than assuming the 13″ measurement is enough. Cross-brand detail is in Will these pool vacuum bags fit my cleaner?
How to check fitment before you order
Measure the opening width of your current bag. Around 13″ (about 33 cm) means our bags fit. Closer to 15″ means you're on the larger professional size. Also check how your bag attaches — ours cinch with a drawcord. If your PK Turbo is an older revision or has been modified — or you're just not sure — send us your cleaner's make and model and we'll confirm fitment before you buy.
Fitting tips (so the bag never pops off)
- Cinch the drawcord tight and lock it before you start.
- Lower the cleaner in gently so trapped air escapes through the mesh instead of ballooning the bag off the frame.
- Rinse fine bags often — once pores below 100 micron clog, flow drops fast.
- Empty at about two-thirds full — a packed bag chokes suction and can spill debris on lift-out.

FAQ
Do these bags fit the BWT PK Turbo EV105TURBO?
Yes — all our bags are the 13″ spa-width size the PK Turbo uses. Measure your current bag's opening if your unit is an older revision, or send us the model and we'll confirm.
Are these genuine BWT bags?
No — they're our own Australian range in the same 13″ spa-width fit, available in more micron options (from 40 micron super-fine up to a 3 mm leaf bag) than the originals — and priced from $44.95.
Can I get a finer bag than the PK Turbo's stock fine bag?
Yes — the 57 micron and 40 micron bags both have a smaller nominal opening than the 75 µm stock fine bag, so they capture silt, dust and dead algae that otherwise passes straight through. Our 80 micron is the closest nominal match to the stock fine bag rather than an improvement on it.
What if I'm replacing the whole cleaner, not just the bag?
The Bottom Feeder cordless pool vacuum runs this entire bag range natively, has a fully repairable aircraft-grade build, and comes with full Australian warranty and Australian-based support.
