Performance & placement tips

- Placement: keep central airflow pathways clear to maximize premium performance potential.
- Value lens: performance can be excellent, but conversion depends on whether premium features matter to your routine.
Filter replacement costs
Instead of guessing from one-time sale prices, treat filter costs as part of the ownership decision. Use this quick pre-buy checklist:
- Review annual ownership cost, not only launch pricing.
- Confirm exact replacement filter options that match your sensitivity priorities.
- Heavy-use environments may require earlier filter swaps than baseline estimates.
- Plan maintenance timing up front to protect premium-performance consistency.

- Need compact bedroom pick: Levoit Core 300P
FAQ
Is this a “True HEPA” air purifier?
Manufacturers use terms like “True HEPA” and “HEPA-grade.” Confirm the exact filtration spec and any test documentation on the listing you’re buying.
Is it good for allergies?
Many people use HEPA-grade purifiers for allergens. Results depend on right sizing (room/coverage), placement, and continuous use.
Will it remove odors or smoke?
HEPA media targets particles; odors/VOCs generally need activated carbon. For smoke/odors, prioritize carbon content + airflow.
