HEPA filters are ideal for those with allergies or respiratory conditions. They are designed to remove almost all airborne particles, including microscopic allergens and bacteria. High-efficiency filters, also known as HEPA filters, provide the highest level of filtration. Generally, pleated filters should be replaced every 2-6 months, depending on usage and the level of indoor air pollution. Pleated filters can capture pet dander, pollen, mold spores, and more. They are made of polyester or cotton fibers folded into pleats, increasing the surface area for trapping smaller particles. Pleated filters are an upgrade from fiberglass filters, offering improved filtration efficiency. Fiberglass filters are typically disposable and need to be replaced every 1-2 months. While they are effective in capturing larger particles, they provide minimal filtration for smaller particles and allergens. They consist of layered fiberglass fibers that trap larger particles like dust and lint. Here are the three most common types of furnace filters:įiberglass filters are the most basic and affordable option. The frequency with which you need to change your filter depends on what type it is along with some other circumstances we will discuss later on. So, let’s dive in! How Often to Change Furnace Filterįurnace filters come in different types, each with its own characteristics and benefits. We’ll discuss various types of filters, their recommended replacement intervals, and guide you step-by-step through the process. While this may seem like a small maintenance task, it plays a crucial role in maintaining indoor air quality and optimizing your HVAC system’s performance. Oven filters help keep your house cleaner by trapping dust, dirt, pollen, carpet fibers, pet dander and other airborne particles before they enter your system and damage your fan or heating coil.We’re going to walk you through the ins and outs of changing your furnace filter. You may need to measure your air duct if you find that your filter is too small or too large. When installing a new filter, make sure that the air flow arrows on its side point in the correct direction towards the fan and away from cold air.If you don't have access to your unit's instruction manual, most air filters are located in the oven fan compartment (remove the oven cover by lifting it up) or embedded in metal ducts before the fan. Studies show that medium-efficiency filters in the MERV range of 7 to 12 achieve the best balance between allergen removal and cost of the filter. When air filters are clogged, your HVAC system has to work harder to produce the same amount of air for your home. Basic household air filters for ovens are designed to trap dust, dirt, and airborne particles before they enter the system and can damage the fan or heating coil.You can change the air filter in HVAC systems that use hot and cold air to condition the temperature. It is important to replace air filters regularly for the overall condition of your HVAC system and your family's health. As mentioned above, oven filters are usually located near where cold air enters the oven, in the cold air return duct, or at the inlet of the fan chamber (or sometimes in both places). The air filter is usually located inside the air duct system or the indoor HVAC unit itself.You may not have noticed it yet, but the air filters are located inside the indoor unit, just below the front panel. Oven filters are specifically designed to work in oven systems, so it is best to turn them off completely when replacing the filter. To begin, open the ventilation grille and remove the used filter.In a downflow configuration, your air controller or downflow furnace blows cooled or heated air downward. It is important to deactivate the system before replacing the filter, as this will prevent dust and sand from entering the system. Are you wondering in which direction the air flow arrow should point when replacing a furnace filter? The exact location of the filter will depend on the airflow configuration.
