Because of the hot and humid weather in Singapore, AC systems are a necessity. But many people forget one important thing\u2014cleaning the aircon filters.<\/p>\r\n\r\n\r\n\r\n<p>When the filters are dirty, your AC has to work harder, which uses more electricity and cools your home less. Even worse, it can circulate dirty air into your home.<\/p>\r\n\r\n\r\n\r\n<p>This guide will show you how to clean aircon filters to keep the air in your home fresh.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">What Aircon Filters Do<\/h2>\r\n\r\n\r\n\r\n<p>An aircon filter, or simply a filter, traps unwanted particulate matter in the air as it passes through its mesh. In general, they improve indoor air quality around the space but only when you keep your AC filter clean.<\/p>\r\n\r\n\r\n\r\n<p>The filter can remove more contaminants from the air the finer its mesh is.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Common Types of Filters<\/h2>\r\n\r\n\r\n\r\n<p>You must understand what type of aircon filter you have before cleaning it. Different filters need different care, and some shouldn\u2019t be cleaned at all.<\/p>\r\n\r\n\r\n\r\n<p>Here are the most common types in Singapore.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Fibreglass Filters<\/h3>\r\n\r\n\r\n\r\n<p>These are the most basic and cheapest filters. They are made from thin layers of fibreglass and mainly catch bigger dust particles.<\/p>\r\n\r\n\r\n\r\n<p><strong>What you should know about <\/strong><a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/fiberglass-filter\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><strong>fibreglass filters<\/strong><\/a><strong>:<\/strong><\/p>\r\n\r\n\r\n\r\n<ul>\r\n<li>Cheap and disposable<\/li>\r\n\r\n\r\n\r\n<li>Usually have a cardboard frame<\/li>\r\n\r\n\r\n\r\n<li>Only catch large dust, not tiny allergens<\/li>\r\n\r\n\r\n\r\n<li>Not washable (replace when dirty)<\/li>\r\n\r\n\r\n\r\n<li>Lower filtration efficiency<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>These filters are okay for basic use but not great for dusty and humid environments.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Pleated Filters<\/h3>\r\n\r\n\r\n\r\n<p>These filters are made of folded (pleated) fabric or paper, which gives more surface area to trap dust and dirt.<\/p>\r\n\r\n\r\n\r\n<p><strong>What you should know about pleated filters:<\/strong><\/p>\r\n\r\n\r\n\r\n<ul>\r\n<li>Better than fibreglass at catching small particles<\/li>\r\n\r\n\r\n\r\n<li>The folded design helps trap more dust<\/li>\r\n\r\n\r\n\r\n<li>Medium price<\/li>\r\n\r\n\r\n\r\n<li>Some are washable, others are not<\/li>\r\n\r\n\r\n\r\n<li>Good for homes with mild allergies<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>These filters balance performance and cost, making them a common choice.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">HEPA Filters<\/h3>\r\n\r\n\r\n\r\n<p>HEPA stands for High-Efficiency Particulate Air. These filters remove very small particles and are great for people with allergies or asthma.<\/p>\r\n\r\n\r\n\r\n<p><strong>What you should know about HEPA filters:<\/strong><\/p>\r\n\r\n\r\n\r\n<ul>\r\n<li>Can trap small particles (as small as 0.3 microns)<\/li>\r\n\r\n\r\n\r\n<li>Ideal for allergy and asthma sufferers<\/li>\r\n\r\n\r\n\r\n<li>Used in spaces where high air purity is needed<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Electrostatic Filters<\/h3>\r\n\r\n\r\n\r\n<p>These filters use static electricity to pull in dust and particles. Some can be washed and reused.<\/p>\r\n\r\n\r\n\r\n<p><strong>What you should know about electrostatic filters:<\/strong><\/p>\r\n\r\n\r\n\r\n<ul>\r\n<li>Can be washable or disposable<\/li>\r\n\r\n\r\n\r\n<li>Acts like a magnet for dust<\/li>\r\n\r\n\r\n\r\n<li>Better for the environment if washable<\/li>\r\n\r\n\r\n\r\n<li>Good at catching small to medium particles<\/li>\r\n\r\n\r\n\r\n<li>Mid-price, but washable ones save money over time<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>Washable electrostatic filters work well in Singapore since they can be cleaned often to avoid mould.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">How to Know If Your Filter Is Washable or Disposable<\/h3>\r\n\r\n\r\n\r\n<p>If you are not sure if your filters can be cleaned, refer to the guide below.<\/p>\r\n\r\n\r\n\r\n<ol style=\"list-style-type: lower-alpha;\">\r\n<li>If it has cardboard edges, it is likely disposable. Do not wash.<\/li>\r\n\r\n\r\n\r\n<li>Check the labels and look for words like \u201cWashable\u201d or Disposable\u201d on the frame.<\/li>\r\n\r\n\r\n\r\n<li>\u00a0Washable filters feel stronger and often have plastic frames. Paper-like ones are disposable.<\/li>\r\n\r\n\r\n\r\n<li>Refer to your AC manual as it will tell you what type of filter to use and how to maintain it.<\/li>\r\n\r\n\r\n\r\n<li>Washable filters usually have arrows moulded into the plastic frame, not just printed on cardboard.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p><strong>Important tip:<\/strong> If you are still unsure, it is safer to replace the filter than risk damaging your aircon or breathing dirty air.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">How Dirty Filters Affect Energy Efficiency and Electricity Bills<\/h2>\r\n\r\n\r\n\r\n<p>When your aircon filter is full of dust, pet hair or dander, or mould, it blocks the airflow. Here is a simple explanation of how your AC needs to operate harder just to keep your room cool.<\/p>\r\n\r\n\r\n\r\n<p>With a clogged filter, the fan has to push harder to move the air. And when air cannot flow freely, it takes longer to cool the room. So your aircon stays on longer and uses more energy.<\/p>\r\n\r\n\r\n\r\n<p>If your filter is really dirty, your aircon might cool up to 20 to 25% less effectively. That means you\u2019re paying more money but are less comfortable.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Signs That Your Filter Needs Cleaning<\/h2>\r\n\r\n\r\n\r\n<p>Let\u2019s discuss the <a href=\"https:\/\/glutenfreepleasure.com\/__proxy_domain\/kungfuhelper.com.sg\/blog\/5-warning-signs-your-aircon-compressor-needs-urgent-cleaning-service\/\" target=\"_blank\" rel=\"noreferrer noopener\">warning signs<\/a> that your filter needs cleaning or replacement.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Weak Airflow<\/h3>\r\n\r\n\r\n\r\n<p>If\u2026<\/p>\r\n\r\n\r\n\r\n<ol style=\"list-style-type: lower-alpha;\">\r\n<li>The air feels weak even when the fan is on high<\/li>\r\n\r\n\r\n\r\n<li>Some rooms cool slower than others<\/li>\r\n\r\n\r\n\r\n<li>Cooling feels uneven around your home<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Strange or Musty Smells<\/h3>\r\n\r\n\r\n\r\n<ol style=\"list-style-type: lower-alpha;\">\r\n<li>A musty or mouldy smell when you turn on the AC<\/li>\r\n\r\n\r\n\r\n<li>A dusty or \u201cdirty sock\u201d odour from the vents<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>These smells could mean mould or bacterial growth in the filter.
