Designed and manufactured in the UK, the award-winning fan is built specifically to meet the rigours of social housing, where there is a need to remove moisture and improve indoor air quality throughout the dwelling, while offering long-term performance with minimal maintenance.

The innovative exchangeable cartridge system was welcomed by social landlords on release, as it provided the lowest-ever lifecycle costs, saving housing providers hundreds of thousands of pounds in maintenance and replacement fees.

For this reason, the Filterless Infinity Fan is designed to avoid unnecessary disposal. The Filterless Infinity Fan is also known for its whisper-quiet running, ultra-low energy consumption, and variable speed control.

The latest updates to the Filterless Infinity Fan include an integrated data logger function. This helps social landlords monitor fans in residents’ homes, including running conditions, energy usage and operational life.

James Kane, Head of Social Housing (Sales) at envirovent, said:

“We are proud to be celebrating this significant three million milestone for our Filterless Infinity Fan, as it really is one of our most successful products ever.”

“We have innovated on the original model over the years, most recently to meet modern requirements for data logging and monitoring, enabling social housing providers to better meet the requirements of Awaab’s Law.”

“We’re excited to share that this fan is still manufactured in the UK by our people, who are passionate about indoor air quality and providing the very best ventilation solutions to our customers.”

envirovent’s Filterless Infinity Fan has won several top industry and national awards, including the Queen’s Award for Enterprise: Innovation (2009), the H&V News Domestic Heating and Ventilation Product of the Year (2019), and the BCA Innovative Product of the Year (2025).

envirovent created the Filterless Infinity Fan by designing out the requirement for filtration to ensure a smooth, uninterrupted passage of air through the fan.

It uses filterless technology, with a unique patented cartridge system and ultra-low-watt motor technology. The environmentally friendly unit provides exceptional performance and is designed to last the lifetime of a building.

These fans have also helped prevent several tonnes of replacement extractor fans from going to landfill sites, while reducing the amount of plastic used in replacement units and therefore producing less CO2 emissions.
