I have found that I depend less on Claritin every morning, for which I am eternally grateful. I tried the MERV 13 air filter and it significantly reduced the efficiency of our central air conditioner, although the filter itself appeared like it wasn't letting anything through. This filter is less fluffy, gets dirty a little faster, but is actually suitable for the air conditioning system and allows it to work closer to normal operation. Compared to cheap synthetic fiber filters, this thing is exceptional. I haven't had to vacuum the fins behind the filter since I started using better filters over a year ago. Whereas cheap filters require me to clean them every month.
