What types of filters should you look for?

• Pre-filter: Catches large particles (hair, lint, pet fur) and protects finer filters. Often washable or replaceable.
• True HEPA (H13 / H14): Gold standard for particle removal — captures ~99.97% of particles ≥0.3 μm (dust, pollen, mold spores, many viruses/bacteria droplets). Look for H13/H14 if you want the highest efficiency.
• Activated carbon: Important to reduce odors, VOCs (cleaning fumes, paint smells), and smoke molecules — essential for homes near wildfires or heavy cooking.
• Specialty filters / tech: Some brands use additional tech (electrostatic charging, photocatalytic filters, antibacterial coatings). These can help with certain pollutants but evaluate lab tests and certifications when choosing.

How to choose the right model for your home

1. Match coverage to room size: Use CADR and manufacturer coverage numbers. If you have an open plan, choose higher coverage (or multiple units).
2. Check filter costs & availability: Replacement filters are recurring costs — check Amazon listings for filter prices and bundles.
3. Look for sealed HEPA designs if you want guaranteed trapping (Dyson & Coway are sealed designs).
4. Smart features vs simplicity: Smart controls (apps, voice) add convenience; simpler models can be more reliable and cheaper.
5. Noise & speed control: If bedroom use is important, prioritize quiet sleep modes and low minimum fan speeds.

Final Thoughts / Conclusion

Investing in a high-quality air purifier is an impactful way to improve day-to-day comfort, reduce allergy symptoms, and protect your home during smoke or high-pollution events.
