List of EPA Certified Forced-Air Furnaces

EPA provides a list of all EPA Certified Forced-Air Furnaces (XLS)(1 pg, 19 K, June 2018) (a.k.a. “warm air furnaces”) that are in compliance with the 2015 Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces at 40 CFR Part 60 (Subpart QQQQ) (2015 Wood Heater Rule).  This list contains the following records:

  1. Manufacturer’s name
  2. Model name
  3. Fuel used during certification test
  4. Annual average emission rate (lb/mmBtu)
  5. Maximum heat output rating (Btu/hr)
  6. Efficiency (%HHV)
  7. Carbon monoxide
  8. Whether the appliance is 2020 NSPS certified.  

Pursuant to the 2015 Wood Heater Rule, each FAF manufactured, imported into the United States, or sold at retail must be certified to comply with the following applicable particulate matter (PM) emission standards and other requirements such as having a quality assurance program in place for each certified model line.  

For the PM emission limits, the FAFs are divided into two categories – small and large – depending on their heat output.

Heat Output (BTU/hr) 2016 / 2017 Standards 2020 Standards
Small forced-air furnaces
< 65,000 BTU per hour
On May 16, 2016: PM emission limit ≤ 0.93 lb/mmBtu heat output (weighted average, using cord wood or pellets) On May 15, 2020:  PM emission limit ≤ 0.15lb/mmBtu heat output (individual burn rate, using cord wood or pellets)
Large forced-air furnaces
≥ 65,000 BTU per hour
On May 15, 2017:  PM emission limit ≤ 0.93 lb/mmBtu heat output (weighted average, using cord wood or pellets) On May 15, 2020:  PM emission limit ≤ 0.15lb/mmBtu heat output (individual burn rate, using cord wood or pellets)
