MERV 5, you can probably see visible holes in the filter having that low of filtration rating.

That's not the bad thing you may imagine it to be. Having a higher MERV rating could easily overwork your AC unit. Like sucking a golf ball with a straw

Yes, I've heard anything merv13 or higher is not recommended for residential units. We typically use merv11 for our home.

Project Farm on the tube did an episode and was determined based on static pressures that MERV 5-8 was best especially for newer units with x13 blower motors.
