Every plastic container or bottle has a recycling symbol. The symbol is a number, ranging from 1 to 7, within a triangle. While you may think nothing of these symbols, they can actually offer a great deal of information regarding the toxic chemicals used in the plastic, how likely the plastic is to leach, how un-bio-degradable the plastic is, and ultimately the safety of the plastic.

The Bottom Line: Which Recycling Numbers to Avoid, Which are ‘Safest’

In the end, it’s really best to avoid using all plastics if you’re able. But at the very least:

Avoid recycling symbols 3, 6, and 7. While Number 1 is considered safe, it is also best to avoid this plastic.

Look for symbols 2, 4, and 5, as these plastics are considered to be safest. These are the plastics to look for in terms of human and animal consumption.

In the end, plastics will still be used, but you can certainly limit your use of the product. Instead of buying plastic water bottles or other plastic containers, choose glass or invest in a high quality water filtration system to obtain your water from. (This is best for your health anyway).
