Our purifier and ionizer with IOP4 technology

IOP4 technology is based on a chemical-free decontamination technique that has been proven and approved in the medical community for over ten years.


What is the difference between Defender7 and
Protect ?

Defender7 and Protect do not use the same technology to clean the air. The Defender7 uses OXP technology based on photocatalysis and the Protect uses IOP4 technology based on cold plasma.


The features and their designs are different, as well as their facilities. The Defender7 is installed on VMC double flow systems and ventilation ducts. The Protect is installed on air conditioning system cassette and split, truck and refrigerated container. See Defender7 product sheet and See Protect product sheet.

Should the windows and doors be kept closed for the Protect to be effective ?

To optimize the use of the device, keep the windows closed. Protect purifies best when the rooms are not exposed to other sources of pollution. However, we advise you to open the windows in the morning and evening to ventilate the rooms, knowing that you are bringing in sources of external pollution. Once the windows are closed, the Protect can effectively neutralize them.

What is the noise level of the Protect ?

The Protect does not produce any sound.
