Types of Furnace Filters


There are a lot of important things to remember when it comes to home improvement and home maintenance, and furnace filters are one of those things that are important but easily neglected. Finding the right furnace filter will not only save you money, but it will improve air quality! Originally, filters were built to protect the inside portion of the furnace, but now filters can do more than that – they will even prevent harmful particles from circulating back into the air that you breathe. Here are the most common options for furnace filters:

  1. Disposable fiberglass:
    These are one of the most common filter options and it doesn’t do much more than prevent large particles of lint, debris, or dust from clogging your system, but they are not good for cleaning the air itself. They’re inexpensive and are not good for those that live with asthma or allergies.
  2. Disposable pleated:
    This is a popular option that consists of cotton paper or polyester. It’s inexpensive, made from green materials, and is effective in removing some small particles like mites and spores. However, these require frequent changing in order to prevent clogging of your HVAC system.
  3. Disposable electrostatic:
    These are made with self-charging electrostatic cotton or paper fibers that will trap small particles. They are affordably priced, but can get more expensive if you need a custom size. They are great for homes with smokers or pets.
  4. Permanent electrostatic:
    These are also made of self-charging electrostatic fibers and permanent options have removable, machine-washable filters that can be removed and used for up to eight years.
  5. High-efficiency pleated:
    These are made from pleated 4-5” pleated synthetic cotton and are attached to a firm metal grid that prevents leaks. These will filter out the smallest of particles and are wonderful for those that live with respiratory issues or other autoimmune diseases. They are commonly seen in hospitals because of their effectiveness, but are expensive and may not be available for installation in all areas.
