Just saying that MERV 8 is safer than MERV 13 is complete nonsense.There is no simple relationship between MERV ratings, pressure drop, and filter manufacturers. Numbers are all over the place.
For example, the 3M Filtrete 20x25x1 300 MPR (MERV 5) has a higher pressure drop than the 3M Filtrete 20x25x1 1900 (MERV 13) because the MERV 13 model has more pleats, resulting in a larger surface area.
If done properly, increasing the number of pleats per inch generally increases the filter's surface area, which can reduce pressure drop, assuming other factors like pleat depth and filter material remain the same.
To simplify, when the surface area increases, the air has more space to pass through, which typically reduces resistance (pressure drop) because the air can flow more easily through the larger surface area.
I have yet to find a MERV 8 (or lower) 20x25x1 filter that is easier on my furnace than the 3M Filtrete 20x25x1 1900 MERV 13. Don't speculate – measure it, or open that Physics II book already.

Stick with a lower MERV rating (like from your link!) and use individual air purifiers in rooms.

I use the blue or green ones, the fiberglass type. Used it for years, no problem.
