It helps you \u201csee\u201d and \u201cchoose\", turning passivity into action. In AUTO mode, it automatically adjusts fan settings based on air quality, making your life even more convenient.<\/li><li>Extending Lifespan of Filter: Experiments have found that our purifier has added water-washed filter elements, reducing the replacement frequency by 30%. This has effectively controlled the usage cost for customers.(We suggest replacing the filter regularly to ensure the filtration effect.)<\/li><li>Enjoy Fragrant Air: Add 4-5 drops of essential oil to the top aromatherapy pad and enhance your indoor air with your favorite scent. The fragrance will circulate indoors with the fresh air, providing you and your family with a healthy and comfortable environment and a pleasant aroma.<\/li><li>True H13 Filtration: The advanced H13 four-layer filtration system achieves a capture rate of 99.97% for particles as small as 0.3 microns and also has an excellent interception effect on particles as small as 0.1 microns. Choose our purifier and make your living space purer and more vibrant.<\/li><li>Choose Your Sleep Mode: We have noticed that not only the sound of the fan can affect sleep quality, but also the light and button sounds of the purifier can seriously affect sleep. A more flexible combination of sleep modes, one-click mute and light off, choose the sleep state that suits you.<\/li><\/ul>        <\/div>\n    <\/div>\n\n    <div class=\"aawp-product__footer\">\n\n        <div class=\"aawp-product__pricing\">\n            \n            \n                    <\/div>\n\n                <a class=\"aawp-button aawp-button--buy aawp-button aawp-button--green\" href=\"https:\/\/www.amazon.com\/dp\/B0FM3ND4J3?tag=romanceunivers-20&#038;linkCode=osi&#038;th=1&#038;psc=1&#038;keywords=open%20air%20filter\" title=\"View Product\" target=\"_blank\" rel=\"nofollow noopener sponsored\">View Product<\/a>\n            <\/div>\n\n<\/div>\n\n            \n            \n<div class=\"aawp-product aawp-product--horizontal aawp-product--style-standard aawp-product--bestseller aawp-product--ribbon\"  data-aawp-product-asin=\"B000BO68BU\" data-aawp-product-id=\"5143817\" data-aawp-tracking-id=\"romanceunivers-20\" data-aawp-product-title=\"Frost King Air Conditioner Filters 15 in x24 in x3\/16 in  Open Cell Foam\" data-aawp-geotargeting=\"true\">\n\n    <span class=\"aawp-product__ribbon aawp-product__ribbon--bestseller\">Rank No. #4<\/span>\n    <div class=\"aawp-product__thumb\">\n        <a class=\"aawp-product__image-link\"\n           href=\"https:\/\/www.amazon.com\/dp\/B000BO68BU?tag=romanceunivers-20&linkCode=osi&th=1&psc=1&keywords=open%20air%20filter\" title=\"Frost King Air Conditioner Filters, 15 in. x24 in. x3\/16 in. , Open Cell Foam\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41xVrpR4BOL._SL160_.jpg\" alt=\"Frost King Air Conditioner Filters, 15 in. x24 in. x3\/16 in. , Open Cell Foam\"  \/>\n        <\/a>\n\n            <\/div>\n\n    <div class=\"aawp-product__content\">\n        <a class=\"aawp-product__title\" href=\"https:\/\/www.amazon.com\/dp\/B000BO68BU?tag=romanceunivers-20&linkCode=osi&th=1&psc=1&keywords=open%20air%20filter\" title=\"Frost King Air Conditioner Filters, 15 in. x24 in. x3\/16 in. , Open Cell Foam\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            Frost King Air Conditioner Filters, 15 in. x24 in. x3\/16 in. , Open Cell Foam        <\/a>\n        <div class=\"aawp-product__description\">\n            <ul><li>Manufacturer: THERMWELL<\/li><li>Manufacturer Part Number: F1524<\/li><li>Frost King Washable Foam Air Filter For Air Conditioners, 24X15X1\/4 In. -
