When it comes to air filters, there are many options available. But if you're looking for a filter that is effective, efficient, and long-lasting, then pleated air filters are the way to go. Pleated air filters are made of a flexible material such as polyester, cotton, or paper that is folded to look like an accordion and housed in a cardboard frame. This design gives the filter more surface area, allowing it to capture more particles.
The folds also create an imperfect seal, which means that air will filter through and around the curve without going through the filter completely. This is important because it prevents dirt and debris from building up on the fan, slowing down airflow and degrading performance. It also helps to keep your home's air quality high and prevents a big mess that you'll have to pay to fix or clean later. Pleated air filters are commonly used in home boilers and air conditioning systems, as well as any HVAC system that passes air through ducts.
The main advantage of pleated air filters is that they have more surface area than other types of filters, such as fiberglass filters. This means that they can trap more dirt, dust, and allergens depending on the type of filter you buy. They also have a lower resistance to air flow than other types of filters, so they won't cause your HVAC system to work harder than necessary. Pleated air filters are also available in both reusable and disposable formats.
Reusable filters can be easily recycled since they are generally made of cloth and cardboard. Disposable filters need to be replaced more frequently but are less expensive than reusable ones. In addition to being effective at trapping dirt and dust particles, pleated air filters can also help suppress HVAC fan noise. They also have a higher MERV rating than other types of filters, which means they are more efficient at filtering out pollutants such as smoke, aerosols, odors, fumes, viruses, molds, bacteria, and ambient air particles.
Finally, pleated air filters are a great long-term investment for anyone who doesn't need any special filters or have strong preferences over HVAC filter types. They are durable and chemical-resistant due to their woven fibers of HDPE, UHMW-PE, polypropylene, polyester and PTFE. Plus, an old pleated air filter is more effective than a newer one because of trapped particles which form an additional barrier that improves its filtration capacity.
