Frequently asked questions

What is a Corsi-Rosenthal box best used for?

Bedrooms (allergy/dust relief), schools and offices (cheap clean air at scale), workshops, and smoke or pollen episodes where high airflow clears the air fast.

Where is a CR box not ideal?

Smart living rooms and bedrooms where noise and appearance matter — there, an engineered kit gives the same performance quietly and tidily.

Is it good for wildfire smoke?

Yes — its high airflow clears smoke (fine PM2.5) quickly. Run it harder during episodes with windows shut.
