MERV 5 vs MERV 8, any major difference on system strain?

I’m in a brand new home and have been buying MERV 5 filters and changing them monthly. My landlord recently enrolled me in a service called Filter Easy which sends me MERV 8 filters every 60 days. I’ve always been in the mindset to buy cheaper filters to reduce system strain. Is there a huge difference between MERV 5 and MERV 8? The entire system is brand new, I’m the first tenant.
