Allergist-recommended guidance specifies 4-5 air changes per hour (ACH) for meaningful allergy symptom relief, a specific, checkable target that almost no consumer air purifier marketing states, verify a unit's real ACH against your room size to confirm it meets this threshold.

4 Criteria to Look For Before Buying a Air Purifiers for Allergy
Key buying criteria so you get the right fit the first time.
Target 4-5 ACH for meaningful allergist-recommended relief
This is a specific, checkable target that almost no consumer marketing states directly, verify a unit's real ACH against your room size using its rated CADR.
Ionizer features carry real ozone risk for sensitive allergy sufferers
Some allergy sufferers are also sensitive to ozone byproduct, an 'allergy' purifier with an ionizer feature could exacerbate respiratory symptoms rather than help.
Seasonal allergy sufferers need extra ACH headroom during peak weeks
A unit sized for average year-round need may underperform during peak pollen weeks, consider sizing up or scheduling higher speeds during your worst symptom periods.
Placement and timing matter since settled allergens need disturbance to become airborne
Dust mite debris and pet dander settle on surfaces and are only recirculated into the air by disturbance like walking or cleaning, air purifier timing relative to cleaning activity affects real exposure reduction.
