Hi, apologies if this is an old post. I'm in a similar situation.
A few months back I bought a purifier listed on Amazon as 'PureMate Smart Air Purifier with Ioniser mode, Air Quality Monitor, Display Off, Air Filter', cost about £120 with extra filters being £25ish, I think. That made a big difference though it's already not as good as it was when I first had it - it maybe just needs a new filter (or the old one hoovering!) There are smaller, cheaper versions but I can't comment on how good they are. I got one after seeing a similar post from bigga BBDoom. You probably don't need one with the ioniser or UV light, etc, they don't seem to make much difference? It makes a big difference to have it running while smoking but it's definitely not as 'quiet' as advertised - it also helps (to a lesser extent) if you just run it for a couple of hours after you've gone to bed.
Another thing that might help is to get yourself a good oil diffuser and have a few drops of oil in it that'll help mask the smell - PurEssential makes an oil that helps with smoke odours, and there are similar room sprays that supposedly do the same thing. Lots of stuff online about different diffuser oils that can help to hide smoke smells, etc. In my experience, people notice how 'nice' the room smells rather than anything else 😉😂. We've come a long way from burning some stinky incense (often bad for your breathing) and thinking it does anything other than obviously highlighting that you're trying to cover up a weed smell! Ahhh, the ignorance of my teenage youth! 😂
I've also seen some good smell-proof bags recently (but can't remember what they're called), everything from pencil case to rucksack size - available from Amazon (though I'd caution about having weed-related items in your Amazon history). They'll help reduce the smell if you can be arsed to keep taking everything in and out of it.
Finally, regardless of how 'clear' you think your room smells, get a non-smoking friend in to give you their opinion! You just don't notice the smell as much in your own home if you're constantly around it.
Please let us know if you find something that works well for you. Good luck! 👍
