My friend called me asking what I thought about the Active Gold Air Purifier that his hvac guy was trying to sell him. I don’t have any experience with them. Any links to honest reviews? I haven’t really done residential IAQ in 13 years. In commercial IAQ is ventilation and really big filters lol. Some Medical places will have prefilters which are 2” in thick, then another set after the blower and then a 1 foot thick filter after that.
