# Water-Based Air Purifiers CUE Air Washer Replaces Filters with Water-Based Air Cleaning System By Amy Duong | Published 2026-05-02 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/cue References: [kickstarter](http://kickstarter.com/projects/watervation/cue-air-washer?ref=99n6iy)  The CUE air washer is a [home air purification device](https://www.trendhunter.com/trends/omnipure) that replaces traditional disposable filters with a water-based cleaning system. The CUE air washer uses circulating water to create a 360-degree curtain that captures dust, pollutants, and odors as air passes through it, removing the need for [replaceable filters](https://www.trendhunter.com/trends/shark-neverchange). This approach eliminates the recurring cost of filter replacements, which can reach around $100 annually in conventional air purifiers. The system follows a “washing air” principle inspired by natural rainfall, where particles are physically removed rather than trapped in a dry filter. Captured pollutants are collected in the water tank, which is emptied and refreshed instead of replaced with new components. Additional features include UV-C sterilization to maintain water hygiene and [evaporative humidification](https://www.trendhunter.com/trends/dyson-purifier-humidify) that balances indoor air moisture.
