FAQs
Does this 2‑pack cover my model?
Yes. 900 uses one prefilter, so the pack covers two changes. 900 MAX uses two prefilters, so the pack covers one complete change.
How often should I replace it?
Replace when you notice a decrease in suction or the prefilter looks loaded. In heavy smoke/dust, intervals can be much shorter.
Is the prefilter washable?
The operating guides instruct removal and disposal; no wash/reuse procedure is specified, plan on replacement.
Any safety tips?
Yes, do not use in flammable atmospheres, and turn the unit OFF before plugging in to avoid motor issues.
