It's essential to keep your furnace or HVAC system air filter clean and in good condition. But how often should you check it? A good rule of thumb is to replace pleated filters every 90 days. If you have electrostatic or washable filters, you should wash, dry, and reinstall them once a month. Washable filters are more eco-friendly and, if properly cleaned and reused, can last up to 10 years.

To choose the best furnace filter, it is necessary to adapt it to the specifications of the furnace manufacturer. Filtrete uses the unique 3-in-1 technology to trap lint, dust, pet dander, soot, pollen and mold spores, while encouraging fresh air to pass through the filter. The preferred type of oven filters from the list above are pleated and electrostatic disposable ones, because of their ability to filter lint, dust, pet dander, soot, pollen and mold spores. Changing the boiler air filter every 3 months can prevent it from malfunctioning and, at the same time, contribute to improving indoor air quality and reducing energy costs. The main purpose of a heating filter is not to clean the air you breathe, but to clean the air that passes through the boiler and other air conditioning equipment.

We recommend vacuuming up excess dirt and then running the filter through hot water and allowing the filter to dry completely before using it again. Disposable pleated air filters, a popular option made of polyester or cotton paper, can remove some small particles, such as spores and mites, to improve air quality, but they must be changed frequently to avoid clogging and overloading the HVAC system. Air filters must be changed periodically to help maintain good indoor air quality and to ensure that the HVAC system continues to function properly. Many heater filters need to be changed every 2 to 3 months, so many options include four to six filters per purchase. Also note that thicker oven filters tend to last longer and, over time, provide more filtration, so they usually cost more than 1 or 2 oven filters. The filter is only available in two sizes: 16 inches by 25 inches by 4 inches and 20 inches by 20 inches by 1 inch. To keep your furnace or HVAC system running smoothly and efficiently it's important to check your air filter regularly.

For pleated filters this should be done every 90 days. If you have electrostatic or washable filters they should be washed, dried and reinstalled once a month. This will help maintain good indoor air quality while also reducing energy costs.
