Review on 🌬️ Enhance Air Quality with Nordic Pure 18X24X4 Actual Depth Air Filter by Carl Movahed

The filters came in a large box which was nested tightly within another box so they were in excellent condition. The filters are actually 3.75 inches thick, which is more than normal for a 4-inch filter. I've never bought filters this expensive, but now that I see how little they happen and how much time I save cleaning up dust, it seems absurd not to. My laptop screen no longer needs regular dusting, nor do other surfaces. Airflow is still great. i breathe better I bent the brackets on my HVAC unit to mount these thicker filters. You are SO worth it! A few days to 4 months of use - a little fluff appears. Airflow is still great. My first filter was supposed to last 9 months (only I manage scales here). Hooray!
