It directly affects the health and well-being of occupants, the durability of facilities and overall energy performance. However, indoor air can be up to five times more polluted than outdoor air, where dust, fine particles, allergens and volatile organic compounds (VOCs).\r\nIn light of these findings, buildings must incorporate comprehensive air treatment and control solutions. At the heart of these systems, the HVAC (Heat Ventilation Air Conditioning) unit plays an essential role: it ensures the circulation, conditioning and filtration of air to maintain a healthy and balanced indoor environment.<\/div>\n            <\/div>\n<\/div><div class=\"ArticleEdito\" data-component-id=\"ArticleEdito\">\r\n    <div class=\"ArticleEdito-content\">\r\n        <h2 class=\"ArticleEdito-title\">Operation of the HVAC unit<\/h2>        <div class=\"ArticleEdito-text AppText AppScrollbar\">An HVAC unit, or air handling unit, is the lifeblood of a building or industrial facility. It circulates, treats and regulates the air to ensure a healthy and comfortable environment. In practical terms, it draws in fresh air from outside or a mixture of recycled air, passes it through filters that trap dust and impurities, and then conditions it as needed: the air can be heated, cooled, dehumidified or humidified. Fans then distribute it throughout the premises via a network of ducts. At the same time, stale air is extracted and often directed to an exchanger that recovers some of its heat to preheat the incoming air, thereby improving the energy efficiency of the installation. The whole system forms a balance in which each component contributes to maintaining optimal air quality while limiting energy consumption.<\/div>\r\n            <\/div>\r\n    <div class=\"Image ArticleEdito-image\" data-component-id=\"image\">\r\n        <picture>\r\n            <img class=\"lazyload\" data-src=\"https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Presentation-scaled.jpg\" width=\"1440\" height=\"800\"\r\n                alt=\"Image non trouv\u00e9e\" draggable=\"false\">\r\n        <\/picture>\r\n    <\/div>\r\n<\/div><div class=\"Text2Columns\" data-component-id=\"Text2Columns\">\r\n    <h2 class=\"Text2Columns-title\">Roles and challenges of air quality<\/h2>    <div class=\"Text2Columns-columns\">\r\n        <div class=\"Text2Columns-column AppText\"><ul>\r\n \t<li><strong>Occupant health and comfort<\/strong>\r\nThe presence of fine particles, allergens or volatile organic compounds (VOCs) in indoor air can have a direct impact on health. Their accumulation in enclosed spaces increases the risk of indoor pollution and reduces overall comfort. Properly filtered and regularly renewed air limits these effects while ensuring a healthier and more balanced environment. Temperature and humidity control completes this system by ensuring constant thermal comfort and optimal working conditions.<\/li>\r\n \t<li><strong>Compliance with standards and safety<\/strong>\r\nAir quality management is subject to a demanding regulatory framework. Buildings must comply with specific standards in terms of hygiene, safety and energy efficiency. Appropriate filtration and regular maintenance ensure that installations comply with regulations and contribute to the safety of occupants.<\/li>\r\n<\/ul><\/div>\r\n        <div class=\"Text2Columns-column AppText\"><ul>\r\n \t<li><strong>Installation performance and optimal conditions<\/strong>\r\nIn technical or industrial environments, air control is essential for equipment to function properly. The accumulation of dust or poorly regulated humidity levels can alter sensitive processes, disrupt the accuracy of instruments or accelerate equipment wear. In sectors requiring strict control of conditions, such as clean rooms, air quality becomes a determining factor in maintaining process compliance and stability.<\/li>\r\n \t<li><strong>Energy efficiency and sustainability<\/strong>\r\nGood air quality also contributes to the building&#8217;s energy performance. A well-maintained HVAC system with suitable filters reduces pressure losses and optimises heat exchange. The result: controlled consumption, reduced operating costs and a smaller environmental footprint.<\/li>\r\n<\/ul>                    <\/div>\r\n    <\/div>\r\n<\/div>\r\n<div class=\"ArticleEdito --bg\" data-component-id=\"ArticleEdito\">\r\n    <div class=\"ArticleEdito-content\">\r\n        <h2 class=\"ArticleEdito-title\">Did you know?<\/h2>        <div class=\"ArticleEdito-text AppText AppScrollbar\">In a clean room, a single microscopic particle can be enough to compromise the manufacture of an electronic component or a medicine. ULPA (Ultra Low Penetration Air) filters provide the ultimate barrier against such contamination.\r\nThanks to their extremely dense mesh, they combine several mechanisms to capture both nanoparticles and coarser dust particles. Indispensable in critical environments such as microelectronics, pharmaceuticals and aeronautics, they guarantee the reliability of processes and the quality of the most sensitive products.<\/div>\r\n            <\/div>\r\n    <div class=\"Image ArticleEdito-image\" data-component-id=\"image\">\r\n        <picture>\r\n            <img class=\"lazyload\" data-src=\"https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/White-Room.jpg\" width=\"1440\" height=\"800\"\r\n                alt=\"Image non trouv\u00e9e\" draggable=\"false\">\r\n        <\/picture>\r\n    <\/div>\r\n<\/div><div class=\"Introduction\" data-component-id=\"Introduction\">\n    <h3 class=\"AppTitle h1 theme-reverse\"><\/h3>\n    <h2 class=\"AppTitle h1 theme-highlight\">Filtration, a central component of the HVAC unit<\/h2>\n    <div class=\"AppText\"><\/div>\n<\/div><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"192\" src=\"https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-1024x192.png\" alt=\"\" class=\"wp-image-48876\" style=\"width:1450px;height:auto\" srcset=\"https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-1024x192.png 1024w, https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-300x56.png 300w, https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-768x144.png 768w, https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-1536x288.png 1536w, https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-2048x384.png 2048w, https:\/\/hifi-filter.com\/wp-content\/uploads\/2025\/10\/Aeraulique-Filtration-1568x294.png 1568w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div><div class=\"Text1Column\" data-component-id=\"Text1Column\">\r\n            <div class=\"Text1Column-text AppText\">Filtration plays an essential role in the operation of a HVAC unit. While temperature control, air circulation and energy recovery ensure the comfort and efficiency of the system, it is the quality of the filtration that determines its long-term performance. Every cubic metre of air circulating in the building first passes through a filter device: an invisible but essential barrier against dust, fine particles, pollen and micro-organisms.\r\n\r\nEffective filtration protects both the occupants and the internal components of the unit, such as fans and heat exchangers, by preventing clogging and maintaining a constant air flow. It thus contributes to the reliability of the system, the control of energy consumption and the reduction of maintenance operations.\r\n\r\nHVAC systems incorporate several levels of filtration, adapted to the nature of the pollutants and the regulatory requirements defined by ISO 16890 (air filter classification) and EN1822:2009 (high-efficiency and ULPA filters) standards. These standards guarantee measurable and consistent performance over time, regardless of the context of use.            <\/div>\r\n<\/div>\r\n\r\n<div class=\"Text2Columns\" data-component-id=\"Text2Columns\">\r\n    <h2 class=\"Text2Columns-title\">Our filtration solutions<\/h2>    <div class=\"Text2Columns-columns\">\r\n        <div class=\"Text2Columns-column AppText\"><ul>\r\n \t<li><strong>Pre-filters<\/strong> : They retain the coarsest particles and protect downstream filters.
