FAQ

Short answers win on TikTok traffic.
How do I size an air purifier?

Use CADR/airflow and aim for multiple air changes per hour. If in doubt, size up—then run it on low speed.

Do I need carbon filters?

If you care about odors/smoke, yes. For pollen/dust only, HEPA matters more.

What’s the hidden cost?

Filters. Always check availability and yearly replacement cost before buying.

Where do the links go?

Replace every # with your affiliate link. Keep links consistent: one primary CTA per section.
