They are colorless and odorless, similar to trace elements in water, and belong to imperceptible nourishment. Of course, negative ions are not completely imperceptible. In actual use, there are two typical scenarios that can help perceive the effect of negative ions:<\/div><ol class=\"auto-hide-last-sibling-br\"><li><div class=\"auto-hide-last-sibling-br paragraph-JOTKXA paragraph-element br-paragraph-space\">When the indoor PM2.5 concentration is greater than 75\u03bcg\/m\u00b3, the human body&#8217;s perception of the purification effect of negative ions is weak; however, with continuous use in an environment with good air quality (PM2.5 &lt; 15\u03bcg\/m\u00b3), it is easier to feel that the nasal cavity is unobstructed and the mind is clear when waking up in the morning. This is closely related to the &#8220;clean air field&#8221; formed after negative ions neutralize positively charged pollutants.<\/div><\/li><li><div class=\"auto-hide-last-sibling-br paragraph-JOTKXA paragraph-element br-paragraph-space\">Negative ions reduce suspended particles in the air through the principle of adsorption and sedimentation, thereby reducing irritation to the respiratory mucosa.

Compared with concentration, the quality of negative ions is the core factor determining their performance. This product adopts advanced ESD (Electrostatic Discharge) protection technology, which can accurately block the path of static electricity generation and fundamentally prevent ozone formation. It should be noted that the static electricity voltage is much lower than the voltage required for ozone generation, and our technology cleverly utilizes this characteristic to achieve excellent dual protection effects.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3ff6ab5 e-con-full e-flex e-con e-child\" data-id=\"3ff6ab5\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-730269a elementor-widget elementor-widget-image\" data-id=\"730269a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"786\" height=\"601\" src=\"https:\/\/www.negative-ion.com\/wp-content\/uploads\/2025\/07\/\u9759\u7535\u6d4b\u8bd5\u4e2d\u6587.webp\" class=\"attachment-large size-large wp-image-5216\" alt=\"\" srcset=\"https:\/\/www.negative-ion.com\/wp-content\/uploads\/2025\/07\/\u9759\u7535\u6d4b\u8bd5\u4e2d\u6587.webp 786w, https:\/\/www.negative-ion.com\/wp-content\/uploads\/2025\/07\/\u9759\u7535\u6d4b\u8bd5\u4e2d\u6587-300x229.webp 300w, https:\/\/www.negative-ion.com\/wp-content\/uploads\/2025\/07\/\u9759\u7535\u6d4b\u8bd5\u4e2d\u6587-600x459.webp 600w\" sizes=\"(max-width: 786px) 100vw, 786px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-511f38b e-flex e-con-boxed e-con e-parent\" data-id=\"511f38b\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-d04f0ad e-con-full e-flex e-con e-child\" data-id=\"d04f0ad\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-f017ece e-con-full e-flex e-con e-child\" data-id=\"f017ece\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-59d73ef elementor-widget elementor-widget-heading\" data-id=\"59d73ef\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Ozone-free verification method<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a4058e1 e-con-full e-flex e-con e-child\" data-id=\"a4058e1\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0760b5f elementor-widget elementor-widget-text-editor\" data-id=\"0760b5f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"flex justify-center flex-1 w-full overflow-y-auto messageListContainer-JWrQdW\"><div class=\"flex flex-col flex-1 gap-12 w-full max-w-848 messageList-Sajyge\"><div class=\"flex flex-col w-full group\" data-testid=\"receive-message-foundation\" data-message-id=\"14290264360425218\"><div class=\"flex w-full\"><div class=\"w-full h-fit show-scroll-bar\" data-testid=\"receive-message-box\" data-plugin-identifier=\"Symbol(default-receive-message-box)\"><div class=\"container-ZYIsnH flow-markdown-body theme-samantha-Nbr9UN\" dir=\"ltr\" data-testid=\"message_text_content\" data-show-indicator=\"false\"><div class=\"auto-hide-last-sibling-br paragraph-JOTKXA paragraph-element br-paragraph-space\"><div class=\"auto-hide-last-sibling-br paragraph-JOTKXA paragraph-element br-paragraph-space\">Bring your nose close to the negative ion release end and smell it.
