So Pure Air KT 3 Mobile Air Sterilisation Purifier (KT III Plus)

What size rooms can the KT 3 effectively purify?

The KT 3 is designed for spaces up to 90m² (968 sq ft), delivering 8 complete air changes per hour in rooms of this size. For smaller spaces of 45m², it provides 16 air changes per hour for even more thorough purification. The unit's powerful 100W motor and advanced airflow design ensure effective coverage throughout the entire space, making it perfect for offices, meeting rooms, retail spaces and other commercial environments.

How does the UVGI sterilisation technology work?

UVGI (Ultraviolet Germicidal Irradiation) uses UV-C light to destroy the DNA and RNA of bacteria, viruses and other pathogens. The UV-C light operates within a sealed chamber inside the unit, ensuring safe operation without ozone production. Air passes through the HEPA13 filter first to capture particles, then through the UV-C chamber where remaining pathogens are sterilised. This dual approach achieves 99.99% bacteria removal and 99.9% virus elimination.

What maintenance does the KT 3 require?

The KT 3 requires minimal maintenance with its 5-year warranty coverage. The medical grade HEPA13 filter should be replaced when the system indicates, typically every 12-18 months depending on usage and air quality. The activated carbon filter may need replacement every 6-12 months. The UV-C bulbs have long lifespans but should be replaced according to manufacturer guidelines. The app provides filter replacement notifications to ensure optimal performance.

Can I control the unit remotely through an app?

Yes, the KT 3 connects to the TUYA smartphone app for complete remote control. Through the app, you can monitor real-time air quality data, adjust fan speeds, set operating schedules and receive maintenance notifications. The app works on both iOS and Android devices and allows control from anywhere with internet connection. You can also use the touch controls on the unit itself or the included remote control.

How quiet is the KT 3 during operation?

The KT 3 operates at just 25dB at its lowest fan setting, making it one of the quietest commercial air purifiers available. This noise level is comparable to a whisper and won't disrupt office work, meetings or customer interactions. The precision-engineered motor and sound-dampening design ensure peaceful operation even during continuous 24/7 use in commercial environments.

What do the colour-changing displays show?

The unit features colour-changing displays for PM2.5 (particulate matter) and TVOC (total volatile organic compounds) levels. Green indicates good air quality, yellow shows moderate levels and red warns of poor air quality requiring immediate attention. These real-time displays help you understand your indoor air quality at a glance and determine when to increase fan speeds or activate automatic mode for continuous monitoring.

Is the KT 3 suitable for continuous commercial use?

Absolutely. The KT 3 is specifically designed for commercial environments requiring 24/7 operation. It features robust construction, a powerful 100W motor and medical-grade components built for continuous use. The 5-year warranty demonstrates the manufacturer's confidence in its durability. Independent testing by Airmid Health Group confirms its performance meets commercial air quality standards for offices, schools, retail spaces and healthcare facilities.

What particles and contaminants does it remove?

The KT 3 removes particles as small as 0.1 microns with 99.99% efficiency, including bacteria, viruses, allergens, dust, pollen, smoke particles and fine particulates. The medical grade HEPA13 filter captures these particles, while the activated carbon filter removes odours and volatile organic compounds. The UVGI technology then sterilises captured pathogens, providing comprehensive air cleaning that goes beyond simple filtration.
