The Pros and Cons of Fiberglass Filters
Fiberglass filters are the most common type of filter, and you can find them in most stores in multi-packs. Fiberglass filters provide a basic screen to stop particles and are generally less sturdy than pleated filters; they aren’t designed to last for long.
Pros: The major advantage of these filters is that they don’t cost much. You can usually purchase them from home improvement stores in packs where each filter comes to a little more than a few dollars. They do an effective job against the standard contaminants that can get inside an HVAC cabinet: dust, lint, and dander. They allow for easy airflow and won’t interfere with the blower fan of the HVAC system until they become clogged.
Cons: These filters require frequent changes because they have less surface area and will rapidly develop clogging. We recommend changing a fiberglass filter every month, even if you don’t use the HVAC system that often. The filter strength is also low: it stops big particles, but plenty of smaller ones like pollen and bacteria will slip through. Because they don’t have sturdy construction, fiberglass filters are more prone to collapsing and potentially causing damage to the blower assembly.
The Pros and Cons of Pleated Filters
These are more advanced filters with a larger surface area to trap particles, as well as a stronger weave. You can find them in a variety of sizes, from 1” to 6”.
Pros: Pleated filters have more powerful filtering capabilities so they’ll catch more particles, including smaller ones that can get through a fiberglass filter. The larger surface area and stronger weave mean they need to be changed less often—we recommend putting in a new filter every 3 months, although some 6” filters can last for 6 months.
Cons: These filters cost more to purchase, ranging from $5 to $15. The lower frequency of changes does offset this. For some HVAC systems, a pleated filter may be too powerful and it will restrict airflow and cause a decline in system energy efficiency. Check with our HVAC experts about this.
