The answer to 'how long will air filter last' is that the lifespan of an air filter can vary greatly depending on several factors. Generally, most standard air filters need to be replaced every 1-3 months for optimal HVAC performance and indoor air quality. However, some high-quality filters may last up to 6 months with regular use.
The exact lifespan of your air filter depends on factors like the size of your home, how often your HVAC system runs, the amount of dust and allergens in the air, and whether you have pets or smoke indoors. It's a good idea to check your filter monthly and replace it when it looks dirty or clogged. Regularly changing your air filter helps maintain efficiency, reduce energy costs, and improve the air you breathe.
