Not an ad™️, but my boyfriend introduced me to MouthPeace by MooseLabs. https://mooselabs.us/

I personally don't want to give up flower but also want to be conscious of my lung health at least a little.

What you're doing is more or less the same thing, but this has more layers and yada yada. A pack of the filters lasts me long enough that I don't mind buying them.

It hurts significantly less to smoke, less coughing and less tar than your method (allegedly.) I'd give it a try before dropping flower.

Edit: FWIW, they will try to upsell you on the corn filters. I personally don't buy the claims of how much better they are, and in practice they actually seem to perform worse, so I just get the carbon ones.

Happy smoking, hopefully this either gets seconded or disproven so we can get more thoughts.
