A very good value. Works as good as the original filter.
Filters ae well constructed and a much better value than the original manufacturer's filters. Very functional and easy to slide in. The fit is the same as the original filter.

Unfit products
Terrible product, it won’t fit the machine. Do not purchase!!! I tried to get their tech support, but it won’t let me go through.

Good filter, but mediocre fit as these are slightly bigger than desired
I stopped buying genuine blueair filters years ago due to exponential price hikes every year. I have two 400 series air purifiers with oldest one being 12-years old and still going strong. These filters are mediocre as they are slightly too big so I ended up crushing their sides during install, just to get them to fit. The last set of off brand filters I bought had the metal screen side on the side facing out, which makes more sense to me. These tell you to install the filters with theetal screen side facing inward towards the fan. Fitment alone, I don't plan on buying these again. The performance is what I expected. These might even filter finer particulates as I feel the air purifiers are operating a little bit louder with these filters compared to what I'm used to.

Paper goes out, charcoal goes with air flow.

Matches a Blueair 480i
Compatible with the Blueair 480i, this Classic 400 Series particle filter matches the original layout for a precise fit. I like the straightforward installation that makes routine swaps quick and reduces downtime. The series matched fit cuts guesswork and seats securely. I appreciate the focus on everyday pollutant capture for cleaner airflow. Durable materials help maintain consistent performance between changes.
