The types of air conditioning filters used in your home can have an effect on how often they need to be replaced. If you use standard 1- to 3-inch air filters, it is recommended that you change them every 30 to 60 days if you don't have allergies. If you suffer from mild or moderate allergies, it is best to change your filters more often, about every three weeks. Fiberglass air filters are the more affordable option, but they are not as effective at capturing dust and particles from the air.
These usually need to be changed every 30 days or less. Pleated air filters (such as those manufactured by FilterBuy) should be replaced every 90 days. As the filter accumulates more dirt, dust, and allergens from the air, its efficiency decreases. The more expensive pleated air filters can be changed up to every six months.
However, it is important to never leave an air filter unreplaced for more than 90 days. The lifespan and replacement cycle of the boiler and air conditioner filter are affected by outdoor and indoor air quality. Outdoor air quality can have a big impact on how often the air filter gets dirty and needs to be changed. Furnaces and air conditioners in smaller homes need to pump less air to achieve the same temperature change, which may result in less frequent filter changes.
When it comes to car cabin air filters, how often you need to replace them depends largely on the type of car you drive, the conditions you drive in, and the type of filter you have installed. If your dirty air filter is completely covered with dust and dirt, it's a good idea to replace it even if it hasn't reached the end of its recommended lifespan. During these months, pollutants in your home may increase, but the air filter doesn't catch them. However, you will be putting unwanted pressure on your air conditioning system, which will result in poor air quality and poor air circulation.
If you have allergies, you can reduce symptoms by using a high-quality air filter and adopting a more frequent replacement program. For example, smaller homes need an oven filter or air conditioning system to pump less air with the same temperature change as larger homes, where, of course, more air will need to be pumped. Air filters trap pet hair, dust, and other irritating particles so that the air conditioning system returns fresh, clean air to your home. When you buy a new air filter, you'll find the manufacturer's recommendations for the replacement program.
In conclusion, it is important to keep in mind that the frequency of replacing your AC filter depends on several factors such as type of filter used, outdoor and indoor air quality and size of your home. It is recommended that standard 1-3 inch filters should be replaced every 30-60 days if no allergies are present while pleated filters should be replaced every 90 days or less. If you suffer from allergies or live in an area with high levels of pollutants it is best to replace your filters more often.
