How to Choose the Right Air Purifier for Allergies
1. Check for True HEPA Certification
Not all filters are created equal. Look for “True HEPA,” which captures 99.97% of particles ≥0.3 microns.
2. Match Size to Room Coverage
Bigger isn’t always better. Choose a model with CADR ratings and square footage that matches your room size.
3. Consider Additional Filtration Layers
Activated carbon is crucial for odors and VOCs, while UV or plasma tech can help neutralize microbes and mold.
4. Noise and Energy Ratings
If it’s too noisy to run overnight, it’s less effective. Seek models with quiet modes and Energy Star certifications.
5. Smart Features vs Simplicity
Do you want app controls, scheduling, and voice activation? Or do you prefer plug-and-play functionality? Decide what suits your lifestyle.
