If ventilation is inadequate, this moisture remains inside the building and can cause windows to fog up and lead to condensation.<\/p>\n<p data-start=\"2230\" data-end=\"2309\">HRV ventilation removes humid indoor air and replaces it with fresh outdoor air.<\/p>\n<h3 data-section-id=\"z8qs9i\" data-start=\"2311\" data-end=\"2349\"><a

data-start=\"2351\" data-end=\"2453\">When we ventilate by opening a window in the winter, we lose the energy used to heat that air along with the air that escapes.<\/p>\n<p data-start=\"2455\" data-end=\"2565\">The purpose of heat-recovery ventilation is to recover a large portion of that energy before the air leaves the building.<\/p>\n<p data-start=\"2567\" data-end=\"2698\">Therefore, the AirOne HRV allows for continuous ventilation of the room without the need to rely on opening windows as the primary ventilation method.<\/p>\n<h3 data-section-id=\"1ptsyof\" data-start=\"2700\" data-end=\"2727\">Works well in a bedroom<\/h3>\n<p data-start=\"2729\" data-end=\"2845\">CO\u2082 concentrations in the bedroom can rise rapidly overnight, especially in new and renovated airtight buildings.<\/p>\n<p data-start=\"2847\" data-end=\"2972\">The AirOne HRV continuously brings fresh outdoor air into the bedroom and removes CO\u2082 and moisture produced by human respiration.<\/p>\n<p data-start=\"2974\" data-end=\"3101\">This makes local heat-recovery ventilation a good solution even when the problem is limited to just one or two rooms.<\/p>\n<h3

data-start=\"3959\" data-end=\"4149\"><strong data-start=\"3959\" data-end=\"3988\">What is HRV ventilation?<\/strong><br \/>\nHRV, or Heat Recovery Ventilation, refers to ventilation with heat recovery. The heat from the exhaust air is used to warm the incoming fresh air.<\/p>\n<p data-start=\"4151\" data-end=\"4320\"><strong data-start=\"4151\" data-end=\"4181\">Does an HRV recover moisture?<\/strong><br \/>\nThe purpose of a standard HRV heat exchanger is to recover heat, not moisture. If you also want moisture recovery, you should choose the ERV version.<\/p>\n<p data-start=\"4322\" data-end=\"4468\"><strong data-start=\"4322\" data-end=\"4363\">Does the AirOne HRV help with high CO\u2082 levels?<\/strong><br \/>\nYes. Ventilation removes stale indoor air and replaces it with fresh outdoor air.<\/p>\n<p data-start=\"4470\" data-end=\"4675\"><strong data-start=\"4470\" data-end=\"4518\">Is the AirOne HRV suitable for a house undergoing renovation?<\/strong><br \/>\nYes. One of the main advantages of a localized solution is the ability to improve ventilation in specific rooms without having to install a ventilation duct system throughout the entire house.<\/p>\n<p data-start=\"4677\" data-end=\"4848\"><strong data-start=\"4677\" data-end=\"4704\">Should I choose an HRV or an ERV?<\/strong><br data-start=\"4181\" data-end=\"4184\"\/>If the problem is excessive humidity, an HRV is often the logical choice. If a well-ventilated home becomes too dry in the winter, it\u2019s worth considering an ERV.<\/p>\n","protected":false},"excerpt":{"rendered":"<h3 class=\"PDq2pG_selectionAnchorContainer\" data-section-id=\"ui48pv\" data-start=\"493\" data-end=\"566\">Blauberg AirOne HRV \u2013 Local Ventilation Unit with Heat Recovery<\/h3>\n<p><strong>The unit will be in stock starting September 25, 2026!<\/strong><\/p>\n<p data-start=\"568\" data-end=\"788\">The<strong data-start=\"568\" data-end=\"591\">Blauberg AirOne HRV<\/strong> is a modern local supplyand exhaust ventilation unit that ensures continuous, controlled air exchange in a room and uses the heat from the exhaust air to preheat fresh outdoor air.<\/p>\n<p data-start=\"790\" data-end=\"978\">The AirOne HRV is well-suited <strong data-start=\"813\" data-end=\"879\">for single-family homes, apartments, bedrooms, living rooms, and home offices<\/strong> where efficient ventilation is desired without the need to install ventilation ductwork throughout the entire building.<\/p>\n<p data-start=\"980\" data-end=\"1213\">Unlike a simple exhaust fan, the AirOne both supplies fresh air and extracts used indoor air.
