Our new PECO+HEPA Tri-Power Filters now have HEPA and charcoal layers, providing even more capturing and purifying power to our PECO filter technology. The material on the outside of these filters has a mixed "salt and pepper" (white and black) pattern, which is different from the solid black material on the outside of the original PECO filters.
Additionally, as we continuously strive to improve our products, there may be variations in filter media color, ranging from off-white/light tan to brighter white. This is normal and should not affect the performance of your PECO filter in any way as long as it is an authentic Molekule filter.
