Review on Activated CF10285 Compatible Corolla Highlander by Scott Holland

They are as good as the other brands I have bought for our Toyota Sequoia. They are impregnated with carbon and have a nice and thick look. When new, they smell fresh and clean. I like to replace them before and after the pollen season and also twice a year. If you swap them out at the beginning of each season (four times a year), you'll likely have better air filtration. possible. Otherwise, every 6 months is a good schedule. I think a year is too long. Of course, this depends on the specific driving conditions. Dusty roads, heavy traffic, smog and other pollutants in the air where you drive certainly play an important role in your oil change intervals. I like to buy bulk packs at a discount and keep them in stock. I think the quality is good and worth the price. 5 Stars.
