FAQs
Does this 2‑pack cover my model?
Yes. 900 MAX uses two pre-filter, so the pack covers one complete change.
How often should I replace it?
When you notice a considerable decrease in air suction. In heavy smoke/fine dust, the filter can reach its limit in weeks.
Do I replace the prefilter at the same time?
Recommended. The prefilter sits inside the particle filter and protects it; replace it if visibly loaded or when suction drops.
Is this a HEPA filter?
No. The 900‑series particle stage is MERV‑13 per the manufacturer’s operating instructions.
Any safety tips?
Yes—remove any accessory hose/duct before opening the top, and keep humidity ≤50% for best overall system performance. Do not use in flammable atmospheres.
