- Aurornis 3y ago> Ratings are important. Yes, but they're not binary. Being slightly undersized doesn't mean it stops working altogether. > For allergies, 4x air changes per hour is recommended. If you have an allergy problem, the last thing you want to do is replace the filtered inside air with outside air every 15 minutes.
- SamBam 3y agoI think the implication is 4 full filtrations per hour, not 4 air changes. Air purifiers still sometimes call this "air changes" or sometimes "equivalent air changes" (e-AC/hr).
