You've heard it before: your HVAC technician is teaching you the importance of changing your air filter. But how often should you do it? The general consensus is that you should replace your home air filter every 3 months or 90 days. But what happens if you let that time go by? Before we talk about when to change your air filter, let's start with why. The most expensive pleated air filters can last up to six months. However, these general guidelines don't consider filter sizes or types, such as thicker filters or smaller filters.
Therefore, it is recommended to never leave an air filter unreplaced for more than 90 days. Some air filters are supposed to survive up to six months, while others must be changed monthly. The denser the air filter, the longer it will last. In general, you can examine the thickness of the filter rather than the brand. You should also take a look at the MERV classification.
Fibreglass air filters are the more affordable of the two, but less efficient at capturing dust and particles from the air. They usually need to be changed every 30 days or less. In smaller homes, the air conditioning system has to move less air, which may mean that air filters are replaced less frequently. However, if you have pets or allergies, you may need to change your filter more often.When it comes to changing your home air filter, it's important to remember that regular maintenance is key. Not only will this help keep your HVAC system running efficiently and effectively, but it will also help keep your family healthy and safe from airborne contaminants.
