ALTERNATIVES
Refrigerants approved by the Environmental Protection Agency (EPA) for USE as substitutes for R-12.

NOTE: Under the Significant New Alternatives Policy (SNAP) program the EPA does not test alternatives for their effectiveness as a refrigerant. The EPA examines alternative refrigerants only for the following characteristics:
- Ozone depletion.
- Global warming.
- Flammability.
- Toxicity.

BLENDS
All approved alternatives (except R-134a) are blends of different refrigerants.

DROP-INS
Because charging one refrigerant into a system before extracting the old refrigerant is a violation of the EPA's SNAP program, the term "drop-in" refrigerants may seem misleading.
