Quick Buying Tips
Go for True HEPA
Only True HEPA filters (not “HEPA-like”) remove 99.97% of small particles like smoke, allergens, and dust.
Consider the Power Source
- Battery-powered: Portable, flexible, but limited runtime
- AC-powered: Better for continuous use, no recharging hassle
Check the Noise Level
Units under 50 dB are ideal for sleeping or office use. Both the PureZone and Conair fall within that quiet range.
Factor in Filter Replacement Costs
Expect to replace filters every 3–6 months. Check Amazon for filter packs—most range from $10–$25
