The best air purifier cleans your air, eliminates household odors, and is easy to operate. The Winix C535 fits the bill with auto fan speed, a HEPA filter, allergen remover, carbon filter, remote control, replacement filters, and sleep mode.\r\n\r\nYou can enjoy a home rid of mold spores, pet dander, smoke, airborne particles, and other allergens while enjoying the white noise and effortless operation of the air filters.\r\nPerformance\r\nThe Winix Air Purifier C535 is easy to use, thanks to the auto feature. While other air purifiers will remain on the speed to choose, the Winix rated air purifier is smart enough to accommodate for how clean or dirty the air is. It will adjust its level of performance based on the number of contaminants in the air. Compare this with another purifier by reading our review titled are HEPA purifiers enough for allergies - as we debunk some HEPA myths.\r\n\r\nThe system does make some noise, but levels 1 and 2 are relatively quiet. You\u2019ll notice more noise if you turn on level 3, and even with the increased noise of level 4, the clean air is noticeably worth it.\r\n\r\nThanks to the auto adjustable performance, the Winix doesn\u2019t waste energy cleaning air that\u2019s already clean, but you\u2019ll also be sure to keep up with the cleaning that does need to be done. Change filters out easily every three months by sliding them in and out of the slot. Clean the rest of the unit with a wet cloth.\r\n\r\nThe Winix C535 can clean rooms as big as 350 square feet, and the real HEPA filter traps particles at 0.3 microns. That includes pollen, mold, odors, smoke, and plenty of other allergens.\r\n\r\nThe fan\u2019s auto feature controls the fan speed and output based on the current air quality, so you don\u2019t have to fiddle with it when it starts running too fast or too slow. In addition to the auto fan speeds, the PlasmaWave feature can filter out things like viruses that other air purifiers can\u2019t.\r\nDesign\r\nOne of the great things about the Winix C535 is that it doesn\u2019t produce ozone, so you\u2019re safe from high ozone levels, unlike many other purifiers. If you do choose to adjust the fan speed manually, the buttons are positioned on the front of the unit. The UV-C light component is entirely safe, too.\r\n\r\nLights on the front of the unit display air quality so you can make better decisions about how to run your fan. It will indicate when you need to check your filter and will adjust the LED sensors automatically based on the brightness in the room.\r\n\r\nThe curved edges and neutral colors will blend in with almost any d\u00e9cor, and it looks sleek and modern rather than big and industrial.\r\nValue\r\nThe value of the Winix C535 comes from less noise and more effortless operation, not to mention the efficient HEPA filter. You can enjoy clean air with minimal effort, and sleek design lets you place it anywhere in your home or office. The Clean Air Delivery Rate, or CADR ratings, are genuinely noticeable and it is on par with the award-winning IQAir HealthPro.\r\nConclusion\r\nFor busy people who continuously struggle with the air quality in their home, the Winix C535 adds a lot of value. Auto mode, sleep mode, and light indicators make everything easy, leaving you to worry about more important things.
