Fresh, Clean Air — Excellent Quality Cabin Filter!
Size: 9.7" x 9.3" x 1.8"
This premium HEPA‑rated filter does an outstanding job of keeping dust, pollen, and tiny airborne particles out of the cabin — much better than standard cabin filters. It’s designed and tested to meet true HEPA filtration standards, effectively capturing up to 99.97 % of particles down to 0.3 microns in size, so the air inside the car feels noticeably cleaner and fresher. Installation was straightforward and fit exactly in place in my vehicle with no modifications needed. The high‑quality filter media feels dense and well‑constructed, with built‑in structural support to help it hold its shape throughout its service life.

Must Buy HEPA Cabin Filter
Size: 9.7" x 9.3" x 1.8"
Great filter and excellent Value! And, it’s a Bosch !!! Description and sizing were exactly as advertised. DIY install was easy and it fit my 2019 Highlander perfectly ! Filter is HEPA and well made and is a good thickness, so much better than the flimsy one the car dealership installed. Impressive ! Highly recommend!
