When it comes to air filters, there are two main types: foam and pleated. But which one is better? In this article, we'll explore the differences between foam and pleated air filters and help you decide which one is best for your needs. Pleated filters are more effective than new foam filters. This is because they have a greater total surface area due to their intricate “zigzag” shape.
This makes them better at trapping dirt and other particles. However, as dirt accumulates with use, foam filters may be more effective due to their greater dust-carrying capacity. Cotton filters are known as “surface load carriers”, meaning that dirt accumulates on the surface of the filter and gradually blocks the airway. If you're looking for an air filter for your oven or air conditioner unit, you can search by filter size or by MERV rating.
Pleated cotton filter material will block faster if a lot of dirt is dumped on the front of the filter. Years ago, pleated filters were made of cotton and air conditioning motors were not very powerful. This can often be overlooked because it allows more air to flow, but it reduces the filtration efficiency of the unit. Fiberglass air filters are much more efficient, safer for the air and HVAC unit, and not much more expensive. However, while a fiberglass air filter may seem like a good idea for your budget, it may not always be the best option for your home, your air conditioning system, or your family's health. Fiberglass filters allow greater airflow when changed regularly because they have less surface area than pleated filters and allow smaller particles to pass through.
If the oil in the foam dries out, it becomes very brittle and can cause parts of the filter to break down. The main purpose of an air filter is to remove pollutants from the air inside the house by introducing them into the air conditioning system. In harsh dusty environments, pleated cotton gauze filters can be extremely resistant to wear and tear. When particles pass through a fiberglass air filter and enter the system, one of two things happens: they either get trapped in the filter or they pass through into the HVAC system. If they pass through into the HVAC system, they can cause damage to its components over time. So which type of air filter should you choose? It depends on your needs and budget.
Pleated filters are more effective than foam filters but may be more expensive. Fiberglass filters are more efficient but may not be suitable for all homes or families. Ultimately, it's up to you to decide which type of filter is best for your home.
