Key features
- HEPA Filter - Cleanable HEPA filter that is highly effective filter that will trap 99.97% airborne particles as small as 0.3 microns including dust, mold, pollen, spore and pet dander.
- Germicidal UV Lamp - Remove micro-organisms such as germs, bacteria and viruses that is trapped or manage to sneak through the HEPA filter.
- Activated Carbon Filter - Remove tobacco smokes, odors, chemicals coming from plastic and paint such as volatile organic compounds (VOCs).
- Ionizer - Disperse negative ions to merge with airborne particles and cause the pollutants easily capture by the air purifier.
- Photocatalytic Oxidation (TiO2) Filter - Together with UV light, this titanium dioxide coated filter will produce ions/ electrons to eliminate chemicals molecules and odor-causing compounds through oxidation.
- Air quality sensor - Sensor technology that monitors surrounding air quality.
- Automatic and Sleep modes.
- Filter change indicator - Diagnostic sensors indicate when filter replacement needed.
- Extremely Quiet Operation.
- Low Replacement Costs.

Design and build quality
Surround Air Intelli-Pro 3 air purifier is measured at 48.3 x 40 x 16.5 cm (19 x 15.7 x 6.5 in) with the weight of 5.4 kg (11.9 lbs). This dull color air purifier is conventionally structured with a considerable square shape, our unit is fitted solidly although there are few unlucky users might suggest otherwise. The buttons/ indicators is uninspiringly designed and placed at front with sensors that will detect ambient air quality; air inlet/ outlet is sufficient in covering the airflow circulation. Inside of the Intelli-Pro air purifier consist of Surround Air’s own 5-stage air cleaning technologies and a powerful yet quiet brushless-DC motor.

Airflow performance and applicable area
With its brushless-DC motor that shoots up 180 cfm, Surround Air Intelli-Pro 3 air purifier should cover an impressive 56 m2 (600 sq. ft.). However during our test, Surround Air Intelli-Pro fails to live up to its height and air-filtration capacity at max speed. Nevertheless it is still capable of removing micro-organism allergens and bacteria on its surrounding. Another plus point will be the low noise generated from the motor at all speed.
Final thoughts on Surround Air Intelli-Pro 3
Surround Air Intelli-Pro 3 is well-price, packed with features and filters durability is applaudable, the build quality is not as solid as some of the top brands, the occasional airflow delivery rate and performance “hiccups” might not be so favorable on its side. Still, if you need an air purifier that is able to handle household particles and pollutants, Intelli-Pro air purifier is your answer.
