I think on the FIR what you need specifically is DIAMOND CARBON PANELS and NO TOXINS used in any of the equipment, i.e., no toxic glues, paints, etc. That being said, I was so worried about making a mistake and so desperate I paid thousands more to get the MPS brand even though there were some others that looked good, and many that were SOOO much less.
Also, you want to be sure to get one with AS MANY PANELS as possible or as much surface on the heater as possible. And I understand that the lower the temperature at which it emits FIR the more effective it is. |
