The Main Kinds of Filters for Gas Furnaces

Gas Furnace Filter

Selecting the appropriate furnace to meet your heating needs can be difficult. There are many options available, but gas furnaces remain a popular option. This is because gas furnaces are low cost, convenient and more efficient.

Among the components that necessitate frequent furnace repair for Salt Lake City residents is the filter. All Hours Plumbing and HVAC notes that knowing the ideal filter to choose for your gas furnace and its needs will help to minimize the required repairs for your furnace. Here are the standard filter options for gas furnaces.

Washable Filters

These are usually made from weaved or pleated aluminum with a few made from plastic and synthetic fiber. The aluminum is rust-proof and has electrostatic properties to collect particles and dust. Though they are more costly compared to disposable filters, washable ones last for 5 to 10 years, are eco-friendly, and typically come with MERV or minimum efficiency reporting value ratings of 1 to 9.

Pleated Filters

These filters are made from spun synthetic fibers with a MERV rating of 5 to 13 and a 1’ to 5’’ thickness. Most pleated filters are non-electrostatic, but their filtration levels enable them to collect even very tiny particles. Though they have lower upfront costs compared to washable filters, they should be changed every 3 to 12 months depending on the manufacturer.

HEPA Filters

HEPA or high-efficiency particulate air filters are particular ones that meet the set standards of the Department of Energy. They comprise randomly arranged fibers typically made of fiberglass and remove over 99% of air particles. HEPA filters sometimes drastically restrict your airflow and should hence only be used with furnaces designed for them.

With proper care, the above filters will significantly enhance your furnace’s operation and longevity. They will ensure the air circulating in your building is free of contaminants and lower your furnace’s energy use. They also trap the particles, which typically cause breakdown of your furnace’s interior parts.
