I don't believe mine was replaced since the original factory one, pulled out old one (typical basic white, nothing special) turned grey/black with a few leaves and lost its ability to flex - like a stale piece of bread/ used f150 from PA, was a fleet rig for 46k miles. Always had a runny nose while driving and had to clear my throat. After replacing I never had to blow my nose or clear my throat, eyes wouldn't seem irritated either. Great filter, does well through dusty construction zones and driving by farms.

Ordered this filter and it came damaged (filter slots were ripped). Advance Auto sent out a replacement, and again it came damaged and not only were the filter slots ripped again but the package was completely squished on one side. My belief is the size of companies like Advance Auto Parts continue to make everything about how much more money they can make, and therefore leading to low quality products and low quality service. Probably last time I shop at Advance Auto, would rather go with a different company and pay more to receive a high quality product and high quality service.
