One filters the exhaust air from your home and protects your MVHR unit, while the other purifies the outdoor air coming into your home, improving your indoor air quality and protecting your health. This helps to reduce the amount of visible dust, lowers energy consumption, ensures quiet operation and extends the life of the system.<\/p>\n<h2>Use and maintenance<\/h2>\n<p>Zehnder recommends replacing the <b>filters every 6 months<\/b> to ensure optimal air quality and system performance.<\/p>\n<p>However, the frequency of changes may vary depending on the following factors:<\/p>\n<ul>\n<li><b>Air pollution levels<\/b> (e.g. urban and rural areas).<\/li>\n<li><b>Allergy or sensitivity to respiratory tract<\/b><\/li>\n<li><b>Keeping pets indoors or smoking<\/b><\/li>\n<li><b>Dust from nearby construction sites<\/b><\/li>\n<\/ul>\n<p>If your system has a <b>filter change indicator<\/b>, follow its warnings. Otherwise, visually check the filters &#8211; if they look very dirty or clogged, it&#8217;s time to replace them.<\/p>\n<h2>Production quality<\/h2>\n<p>This filter set is made by <b>Zehnder<\/b>, a trusted partner with whom we have worked for many years. We buy all our products directly from them, ensuring authenticity and consistent quality. Zehnder has its own production facilities in <b>the Netherlands, France and Switzerland,<\/b> in accordance with high European production standards.<\/p>\n<p>The filters are manufactured using Z-Pleat technology, which significantly increases the surface area of the filter by folding the material into multiple pleats. This pleated design not only improves particle collection, but also reduces air resistance in the system, resulting in a more efficient MVHR unit.<\/p>\n<p>Using <b>genuine Zehnder filters<\/b> ensures that your MVHR system will operate according to the manufacturer&#8217;s specifications, while maintaining optimal air quality and energy efficiency.<\/p>\n<h2>Original product codes<\/h2>\n<ul>\n<li>400100085<\/li>\n<li>400100066<\/li>\n<li>400100065<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Model compatibility Compatible with the following models: Zehnder ComfoAir 350 Zehnder ComfoAir 500 Zehnder ComfoAir 550 What the filter kit protects against The filter set includes 2 filters: Exhaust filter &#8211; G4 (coarse 60%) &#8211; for MVHR protection Supply air filter &#8211; G4 (60% coarse) &#8211; for indoor air protection This filter set complies with [&hellip;]<\/p>\n","protected":false},"featured_media":4306,"comment_status":"open","ping_status":"closed","template":"","meta":{"_how_to_change":"https:\/\/www.youtube.com\/watch?v=_EkdCQ4Nyeg\r\nhttps:\/\/www.youtube.com\/watch?v=4LOBreZs8DY","_delivery_info":"<strong>Order Processing Time<\/strong>\nAll in-stock products are dispatched within 1\u20132 business days, except for clearly marked items with an extended dispatch time (5\u201310 business days).\n\n<strong>Shipping Costs<\/strong>\nShipping is free for all orders over \u20ac59.
