Frequently Asked Questions
Do I need a HEPA filter?
Yes. True HEPA (or H13/H14) captures particles down to 0.3 µm, including fine dust and smoke that aggravate COPD.
Where should I place the purifier?
Close to where you spend the most time—e.g., bedroom at night, living room by day. Keep 15 cm clearance on all sides.
How often do I change filters?
Most purifiers signal every 6–12 months. If wildfire season is heavy or you live with pets, swap sooner.
Final Thoughts
A quality air purifier won’t cure COPD, but it can reduce day‑to‑day triggers that make breathing harder.
