Original Pureatech System filters have the distinguishing reflective grills. If yours don't, then they are not original equipment. The media and filter frames may decompose from the  ultra-violet light exposure and contaminate your air. Don't sacrifice your system's performance, yours or your family's health and risk harmful airborne contaminants or excerssive air flow restriction from inferior filters.  Order your original equipment Pureatech Filters today.                 Click above on Show Me!
