The True HEPA filter in your Winix P450 or U450 air cleaner should be replaced once every 12 months, while the carbon prefilters should be replaced every 3 months for optimal performance. This will ensure that your air cleaner continues to effectively capture allergens, odors, and other pollutants from the air.
