How do the filters compare on grade?
IQAir’s HyperHEPA is a genuine high-efficiency mechanical filter that the company states captures very fine particles, and each unit ships with an individual test certificate — a real strength. The AirPro uses HEPA 14, the highest common consumer HEPA grade defined by the EN 1822 standard, capturing 99.995% at 0.3 microns and 99.9% down to 0.1 microns. Both are proven mechanical approaches; see HEPA 14 Filtration.What about UV-C and odors?
The AirPro pairs its HEPA 14 with an activated-carbon stage for smoke, VOCs, and cooking odors and a fully enclosed UV-C (254 nm) germicidal stage — see UV-C Sterilization. IQAir offers carbon/VOC options on some models but does not use a UV-C stage; its focus is filtration alone.Coverage and noise
The AirPro clears about 430 sq ft in 10 minutes and up to 1,200 sq ft in 30 minutes, running at 25–50 dB (25 dB Night Mode). IQAir’s flagship units are physically large, powerful, and rated for big rooms, but they are heavier and generally louder at higher speeds. For most bedrooms, nurseries, and living rooms, the AirPro’s quiet 25 dB night operation is a practical advantage — see Room Coverage.Quick comparison
No air purifier — premium or value — cures, treats, or prevents any illness. These devices reduce airborne particles and some gases in the air that passes through them. The AirPro is a wellness appliance, not a medical device.
Which should you buy?
Choose IQAir if budget is not a constraint and you want a large, powerful unit with per-unit test certificates and a long track record. Choose the AirPro if you want a verifiable HEPA 14 grade, an added enclosed UV-C stage, quiet 25 dB night operation, and a 60-day risk-free trial at a fraction of premium pricing. For most households comparing performance-per-dollar, the AirPro’s HEPA 14 + UV-C at $169 delivers medical-grade filtration without premium cost. SonoHealth is a Google Top Quality Store (sitewide 4.7 stars across 673 verified reviews — a store-wide figure, not this product’s own rating) and backs the AirPro with a 60-day free trial.Related: AirPro vs. Competitors · AirPro vs. AirDoctor · AirPro vs. Dyson · Best HEPA 14 Air Purifier · Buy AirPro
