It impacts everything \u2014 from our circulation and lung health to how we feel emotionally each day. While taking a walk in the fresh air helps, it\u2019s not enough. Maintaining <strong>good indoor air quality<\/strong> is just as important \u2014 especially considering how much time we spend at home.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Hidden Challenge of Airtight Homes<\/h2>\n\n\n\n<p>With advances in construction technology, energy-efficient homes (A, A+, A++) have become the new standard. These buildings are praised for their <strong>thermal insulation and airtightness<\/strong>, which help reduce heating costs. However, there&#8217;s a trade-off: in airtight homes, <strong>natural air circulation is minimal<\/strong>, making proper ventilation a real challenge.<\/p>\n\n\n\n<p>According to generally accepted standards, indoor air should be exchanged every 2\u20133 hours. But when you open a window in a tightly sealed home, only the immediate area around it (within about 2 m\u00b2) gets ventilated. Sure, you can create a draft by opening multiple windows \u2014 but during winter, this means losing precious heat.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/2-sq.-meters-1024x682.jpg\" alt=\"\" class=\"wp-image-4275\" srcset=\"https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/2-sq.-meters-1024x682.jpg 1024w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/2-sq.-meters-300x200.jpg 300w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/2-sq.-meters-768x512.jpg 768w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/2-sq.-meters-600x400.jpg 600w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/2-sq.-meters.jpg 1199w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>A <strong>Mechanical Ventilation with Heat Recovery (MVHR)<\/strong> system solves this problem. It removes stale indoor air and brings in fresh outdoor air, while recovering and reusing heat in the process. Depending on its capacity, an MVHR unit can exchange <strong>dozens to thousands of cubic meters of air per hour<\/strong>, all while using electricity efficiently. However, there&#8217;s one crucial component that keeps this system running smoothly: the <strong>filters<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why MVHR Filters Matter<\/h2>\n\n\n\n<p>MVHR filters are the gatekeepers of your indoor air. They trap <strong>dust, pollen, soot<\/strong>, and other airborne particles before they can enter your living space. Over time, these filters accumulate pollutants \u2014 and if not replaced regularly, problems begin to stack up.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Here&#8217;s what happens when filters aren&#8217;t changed:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reduced airflow:<\/strong> Clogged filters restrict air movement, reducing the system\u2019s ability to ventilate your home effectively.<\/li>\n\n\n\n<li><strong>Higher energy use:<\/strong> The fan has to work harder to push air through dirty filters, increasing your electricity bills.<\/li>\n\n\n\n<li><strong>Moisture buildup:<\/strong> Poor air exchange leads to higher humidity levels indoors, which can eventually cause <strong>mold<\/strong>.<\/li>\n\n\n\n<li><strong>More noise:<\/strong> The harder the unit works, the louder it gets \u2014 especially noticeable at night when the home is quiet.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-1024x1024.png\" alt=\"\" class=\"wp-image-4277\" srcset=\"https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-1024x1024.png 1024w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-300x300.png 300w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-150x150.png 150w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-768x768.png 768w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-600x600.png 600w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters-100x100.png 100w, https:\/\/filtermarkt.at\/wp-content\/uploads\/2025\/05\/Reasons-to-change-filters.png 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">When Should You Replace MVHR Filters?<\/h2>\n\n\n\n<p>To avoid these issues and ensure optimal performance, it\u2019s recommended to change your filters <strong>every 3 to 6 months<\/strong>. If you live in a <strong>polluted urban area<\/strong>, you may need to do it even more frequently. It\u2019s also a good idea to replace the filters:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Before the heating season starts<\/strong>, and<\/li>\n\n\n\n<li><strong>Right after the season ends<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Clean Filters = Clean Air<\/strong><\/h2>\n\n\n\n<p>By replacing your MVHR filters on time, you\u2019re doing more than protecting a machine \u2014 you\u2019re <strong>investing in your health<\/strong>.
