In terms of the number of baffles and construction, it is what I thought it would be. Which is to say it is good. But the poor boxing of the filters was in a cheap box, and one of the filters was crushed inward and I had to straighten the baffles NOT GOOD!
What's not to love? Quality of product, ease of purchase, and speed of delivery are all best practices with them. Filterbuy has the competitors beat hands down!
Filters cause loud noise every time fans switch on.

These filters are smaller in size than equivalent sized 3M Filterete filters.As a result, they don't fit snugly into the HVAC air intake brackets in the ceiling. This causes them to drop onto the cover plate when the intake fans are off and get sucked up with a loud smack when the fans turn on.
