| UV/Ion | Usually none | Yes — kills pathogens |
| Smart Sensor | None or inaccurate | PM2.5 real-time + Auto |
| Coverage | 15-25 sqm | 30-60 sqm |
| Quiet Mode | 40-50 dB | <30 dB |
| Filter Life | 3-6 months | 6-12 months |

True HEPA H13 vs HEPA H11 — why it matters
- HEPA H11 — captures PM 0.3 at 95% — 5% passes through
- True HEPA H13 — captures PM 0.3 at 99.97% — only 0.03% passes
- 5% difference means what? Room with PM2.5 100 µg/m³:
- H11: 5 µg/m³ left (in real recirculation, 10-15)
- H13: 0.03 µg/m³ (near zero)
- Critical for kids, elderly, allergic — most sensitive to PM2.5
10 reasons AP-907 is better value than budget units
1) True HEPA H13 vs H10-H11 — 100× cleaner
0.03% pass vs 5% pass at 0.3 µm.
2) Activated Carbon included — no separate odor unit needed
Budget units typically have no Carbon layer.
3) Built-in UV/Ion — kills airborne pathogens
Budget = mesh filter only, no pathogen kill.
4) Accurate Smart PM2.5 sensor
Budget sensors inaccurate or missing.
5) Coverage 30-60 sqm vs 15-25 sqm
One unit covers a standard living room.
6) Quiet Mode <30 dB vs 40-50 dB
Bedroom-friendly. Budget too loud.
7) Filter life 6-12 months vs 3-6 months
Less frequent replacement saves money.
8) No ozone emission — safe for kids/elderly
Cheap ionizers may emit irritating ozone.
9) Total cost/year is lower
Cheap upfront, expensive over 3 years with filter replacements.
10) WHD Thai team warranty + parts in country
Imported Marketplace units = no parts.
