Where AirPro Leads
Medical-Grade HEPA 14 Filtration
Most purifiers in this price range use HEPA 13 filters or loosely labeled “True HEPA” filters that only meet HEPA 11 standards. The AirPro’s HEPA 14 filter meets the EN 1822 standard, capturing 99.995% of particles at 0.3 microns — the hardest particle size to trap.Built-In UV-C Sterilization
UV-C light neutralizes airborne bacteria and viruses after they pass through the HEPA 14 filter. Competitors either omit this entirely or sell it as an expensive add-on.1,200 Sq Ft Coverage
The AirPro purifies 430 sq ft in just 10 minutes and handles rooms up to 1,200 sq ft in 30 minutes. Many competitors in the same price bracket top out at 300—500 sq ft.Whisper-Quiet Night Mode
At 25 dB, the AirPro’s Night Mode is quieter than a whisper. Competing models rarely drop below 30 dB, and some exceed 55 dB on their lowest settings.Lifetime Warranty Option
Subscribe to replacement filters (with a 20% discount) and the standard 2-year warranty extends to a lifetime warranty. No competitor in this price class offers a comparable program.Multi-Pack Value
Outfitting multiple rooms is significantly cheaper with AirPro bundles:- 1-pack: 219)
- 2-pack: 124.50 per unit — 43% off)
- 4-pack: 114.75 per unit — 47% off)
