the overall size is a little smaller than the 3M product, so it is debatable on whether the filter does as good of job or not that will lead me to buy more or not. Time will tell.

Seems to do its job.

Seems to do its job. The construction is a little cheap though. Just a thin plain cardboard frame and uneven pleats for the filter. As long as it works, then I guess it's okay.

The manufacturing looks sloppy, the pleats of the filter don't look even. Hope they work

Not sized properly

The filters did not fit properly because they were smaller than the size they were advertised as. The length, width, and thickness were at least .25inch smaller then they were supposed to be.

I have been buying these filters for several years now. They work well here in Minnesota living with many types of tree pollens , especially white pine. The local stores do not carry our larger sized filters. One thing I do like is that they arrive in a good protective box and do not get crushed during shipment.
