I've been using a 3H as needed since mid-2020. The filter is at 90% and I still have a spare. I originally bought it to reduce the PM2.5 count inside the bedroom during bushfires.
It has been great for allergies. When heaps of grass has been cut outside, we end up with the sniffles and sneeze.
Running the 3H for a few hours helps stop the sneezing fits.
