The Winix Signature U450 features our 5-Stage Cleaning System to offer superior air cleaning that captures 99.99% of unseen particles suspended in the air: dust, pollen, pet dander, smoke, mold spores, organic chemicals. Your Signature U450 carbon filters are 3 times more effective, at removing the strongest household odors, than many other disposable carbon filters. The U450 is our largest and most powerful air cleaner and is designed for optimal use in a family room or many other large rooms in your home. Featuring a 5-Stage Air Cleaning System, the U450 uses Washable Pre-Filter to capture large particles like hair, lint and pet fur, helping to extend the life of the HEPA Filter and reduce housekeeping. The U450 Washable Ultimate Filter Cassette and Pre-Filter are treated with CleanCel Anti-Microbial Coating that prevents the growth of odor causing organisms. T he U450 utilizes advanced filter technology to offer you a 99.99% efficient True-HEPA Filter, which captures particles you can't see, including pet dander, smoke, pollen and mold spores. After the air passes through the Pre-Filter and True-HEPA Filter, the Advanced Odor Control (AOC) Washable Activated Carbon Filter traps and absorbs the strongest odors produced from cooking, pets and ammonia. Winix's own PlasmaWave Technology then safely breaks apart odors, chemical vapors, and other pollutants at the molecular level to offer superior all-around air cleaning-without producing any harmful ozone. The Signature U450 also features an Auto Mode, Sleep Mode, Remote Control, and Air Quality Sensor that combine to deliver Set-and-Forget convenience with optimal performance.
