CUE: Stop Filtering Air. Start Washing It.

The Filter Model Has a Hidden Cost

Air purifiers have been a household staple for years, but the filter system they rely on comes with a side of problems most buyers don't consider at purchase. Filters degrade over time, accumulate the very pollutants they capture, and require regular replacement that costs the average household around a hundred dollars a year. Beyond the expense, used filters end up in the landfill. It is a cycle the industry has never had much incentive to solve.

What CUE Actually Does

CUE is a water-based air washer, a category distinct from conventional air purifiers. Rather than passing air through a physical filter, it uses a proprietary system called Rain Tec to spin water rapidly and generate a 360-degree water curtain. Air moves through this curtain, and particles, including dust, harmful gases, and odors, are absorbed into the water instead of being trapped in a filter. The water is replaced regularly, meaning the filtration medium is always fresh.

No Filters, No Chemicals, No Ongoing Cost

The product operates without any chemical agents, relying entirely on water as its cleaning medium. Because there are no filters involved, there is no replacement waste and no recurring purchase required after the initial buy. It also functions as a humidifier simultaneously, adding moisture to the air through natural evaporation as part of the same process.

Where It Stands Commercially

CUE is currently live on Kickstarter, positioning itself in the early adopter market. The company behind it has secured two core patents and filed five additional ones, suggesting a level of technical commitment beyond a prototype stage. The product is available in black and ships to several markets, including the US, UK, Canada, and Australia.
