FRAM CV10370 TrueAir Premium Cabin Air Filter with N95 Grade Filter Media for Select Ford Vehicles

I've been using the Fram N95 air cabin filters in my vehicle for about a year now, changing it every 3 months or less. Even though packages say the filter can last up to 2 years, my opinion is they are visibly dirty by the 3rd month, no matter which brand I've tried. I wish the Fram N95 filter was priced less. Currently the price is double of Walmart's lower end brand called Super(?) ... I've only been able to purchase the Fram N95 in-store once. Never saw them on the shelves after that and so now have been ordering them online. I order 2 of them at a time and am able to receive free shipping. Walmart is excellent with shipping these filters quickly-the package arrived within 3 days. The Fram N95 filter's material is thicker than the lower end (not N95) one. We noticed the Fram N95 eliminates odors longer than the lower end one. The Fram N95 package includes helpful instructions for installation. Walmart: please stock Fram N95 air cabin filters in the stores consistently. Thank you!
