XPOWER's current X-3400A lists its third stage as a 16 x 16 x 2 in thick HEPA filter capturing 99.97% — the same size as this filter. CCW's X-3400 listing gives 99.975% HEPA filtration efficiency. Neither figure is published with a test particle size or test standard for this part.
Stage the filtration or you will pay for it
Filters are designed to work in series: a coarse pre-filter takes the bulk, a media filter takes the fines, and the HEPA takes what is left. Running a HEPA without the stages in front of it does not save money — it loads the most expensive filter in the machine with dust the cheapest one should have caught.
A blocked filter does not stop filtering — it stops flowing
Air scrubbers and dehumidifiers work in proportion to the air they move. As a filter loads, airflow falls, and the machine keeps running and keeps sounding normal while its actual performance drops away. Nothing on the machine tells you. The drying log shows equipment on site; the readings show a job that has stalled.
On fire, construction dust and demolition work, check filters daily.
Handle a used HEPA as contaminated waste
Everything the filter captured is still in it. On a mould, fire or sewage job, bag it as it comes out rather than carrying it through the building.
Changing a HEPA Filter
- Switch off and unplug the air scrubber.
- Wear a P2 respirator and gloves on contaminated jobs.
- Have a heavy-duty bag ready, remove the filter and bag it immediately.
- Check the seal and the housing — a HEPA that is not sealed lets air bypass it, and the efficiency figure no longer means anything.
- Fit the new filter with the airflow direction arrow the right way round and close the housing fully.

The X-3400's standard filtration is three stages: a washable nylon mesh filter, the pleated media filter and the thick HEPA. CCW also lists an H35 HEPA and CF35 carbon filter for the X-3400. XPOWER's current US listing does not describe the H35/CF35 pair, so if you are not sure which HEPA your machine takes, measure the one you are removing and ask us before ordering.

Frequently Asked Questions
How long does a HEPA last?
It depends on the dust load and how well the pre-filters are kept up. With pre-filters changed on condition, the HEPA can last many jobs. Without them, it can be loaded in one. The X-3400's filter change indicator light is the prompt to check it.
Can a HEPA be cleaned and reused?
No. Replace it.
Is this the same as the H35?
CCW lists both. This is the 16 x 16 x 2 in thick HEPA. Measure your filter and ask us if unsure.
Tell us the machine or tool and we will confirm the part before you order.
