The <\/span><b>G4 filters<\/b><span style=\"font-weight: 400;\"> capture approximately 75% of coarse airborne particles, including household dust, larger pollen grains, fibres, sand, sawdust, plant debris and insects. They help reduce dirt accumulation inside the ventilation unit, keeping the heat exchanger, fans and air ducts cleaner. This supports efficient airflow, reduces unnecessary strain on the system and helps extend the unit\u2019s service life.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><b>F7 filter<\/b><span style=\"font-weight: 400;\"> captures approximately 55% of fine particles as small as 1 micron, including fine pollen, mould spores, bacteria-carrying particles, smog, combustion dust and smoke particles. It cleans incoming outdoor air before it enters your premises, helping improve indoor air quality and providing additional protection for people affected by allergies or respiratory sensitivities.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Usage and maintenance <\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To ensure optimal air quality and reliable ventilation-system performance, inspect the filters regularly and replace them when they become dirty or clogged. Under typical operating conditions, filters should usually be replaced every <\/span><b>3\u20136 months<\/b><span style=\"font-weight: 400;\">. However, replacement frequency may vary depending on factors such as:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><b>Air pollution levels<\/b><span style=\"font-weight: 400;\"> (e.g. urban vs rural areas)<\/span><\/li>\n<li style=\"font-weight: 400;\"><b>Allergies or respiratory sensitivities<\/b><\/li>\n<li style=\"font-weight: 400;\"><b>Indoor pets or smoking<\/b><\/li>\n<li style=\"font-weight: 400;\"><b>Dust from nearby construction sites<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If your system includes a <\/span><b>filter change indicator<\/b><span style=\"font-weight: 400;\">, follow its alerts. Otherwise, check the filters visually \u2013 if they appear very dirty or clogged, it is time to replace them.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Manufacturing quality<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">This is an <\/span><b>original Vallox filter set manufactured by Vallox<\/b><span style=\"font-weight: 400;\"> for compatible Vallox 119 and Vallox 149 ventilation units.
