A pleated air filter should be changed every 30-60 days, while a 2-fold air filter must be replaced every 3 months, a 3-fold air filter must be changed every 120 days, and a 4-fold air filter must be replaced every 6 months. However, the only way to be sure of the exact frequency is to inspect the filter visually each month. After a few months, you'll get an idea of how quickly it gets dirty and if you need to adjust the frequency due to any changes in your home. It's essential to understand why changing the air filter regularly is so important.
As the filter captures more dirt, dust, and allergens from the air, its efficiency decreases. This means that if you don't replace it regularly, the air conditioner won't be able to cool your home as effectively and the air quality in your home will suffer. As a general rule, it's best to replace filters at least once every three months. However, some homeowners may need to do this more often depending on certain factors such as the location, age of the air conditioning unit and size of the home.
If you have an asthmatic or allergic person at home, it's recommended to change the filter every 6 weeks for optimal indoor air quality. When it comes time to buy new air filters for your air conditioning system, there are a few things to consider. Pleated filters are usually better than non-pleated filters as they provide a larger surface area to accumulate dust, pet hair and other debris that floats in the air. The only type of filters that trap allergens and spores are HEPA filters or high-energy particulate air filters.
Air filters usually have a MERV (minimum efficiency value) that determines the type and size of contaminants against which the filter acts. Most air filter manufacturers and HVAC companies generally suggest changing the air filter every 90 days or every 3 months. If the dirty air filter is completely covered with dust and dirt, it's a good idea to change it even if it hasn't reached the end of its recommended life. Lower home occupancy extends the life of the air filter while higher home occupancy reduces it.
To guarantee that only clean air comes out of your air conditioning system and that you can breathe better, make sure to replace your air filters as soon as possible. This will also help keep your air conditioner running smoothly and protect the air in your home.
