Review on Spearhead Premium Breathe Filter Activated Replacement Parts best - Engine Cooling & Climate Control by Charles Dean

These cabin filters are awesome! Bought a used car in excellent condition but the cabin smelled strongly of incense. The original filter was installed incorrectly and I had to turn on the fan and put my hand behind the glove box to feel the direction of air movement and install the filter according to the arrow marks on it. The included instructions weren't great, but they nailed it. Now that strong incense smell has been greatly reduced and I have enough filters to drive another 40,000 miles! I can only recommend these filters!
