Indoor air quality plays a crucial role in creating healthy and comfortable living and working spaces. Mitsubishi Electric’s Plasma Quad Technology is changing how we think about air purification. With its ability to neutralise six key indoor pollutants and inhibit 99.8% of SARS-CoV-2*, it is a reliable and advanced solution for improving air quality in homes, businesses, and public spaces.
What Makes Plasma Quad Technology Stand Out?
Plasma Quad Technology is designed to effectively target and neutralise common indoor air pollutants, including:
This bolt-on device significantly enhances the performance of Mitsubishi Electric’s M Series, Mr Slim, and City Multi indoor units. It is a practical way to upgrade both new and existing air conditioning systems, providing a cleaner, healthier environment for all.

How Plasma Quad Technology Works
The system operates in two key stages:
1. Neutralising Harmful Substances
Plasma is produced to break down allergens, inhibit mould, and neutralise viruses and bacteria. It also charges tiny particles like dust and PM2.5 to prepare them for removal.
2. Capturing and Removing Pollutants
A strong electrical field attracts and absorbs these charged particles, ensuring they are no longer circulating in the air.
