If you want to dig into the research on negative ions yourself, I suggest starting with the review studies:

How about NEGATIVE IONS WRIST BANDS that claims that they have negative ions what can you say about it please reply

I always saw my salt lamp as my back up source of salt if the world ends. It will definitely work for that.
I, as a chemist, cringed so hard when hearing this BS (1:01)
Who would’ve thought a silly hunk of salt that you can buy commercially, wouldn’t actually do what it says it can.

This is a cheep shot. If you really wanna flex than go after fake science used by lobbyists founded by our beloved institutions and businesses. 😊 give the bad guys what WE deserve, transparency.
when i was a kid, i’d sit in front of those ionizing filters because i loved that smell

Thanks, you've motivated me to get my negative ion generator fixed - it's a good one that produces next to no ozone, but it stopped working some years back.
11:52 Can you smell the ozone?
Salt lamps with Himalayan salt (it's pink because it's contaminated!) also contains toxic chemicals that can be released into the air and hurt you and your pets.
Please do not let your pets lick the salt lamp! Pets are smaller than you and should not injest too much salt!

I can't believe we live in a country that allows products on the market that don't do what they say they are supposed to do, and especially if they cause harm by releasing pollutants. This is why we need to get the money out of government and especially get the anti-science neanderthals out of office.
I love that science can so easily explain things that people pulling stuff out of their ass or repeating what someone else pulled out of their ass cannot. It's rare that there is ever even a grain of truth to woo woo ideas, but it's good to know what is and isn't true if there is some truth there.

So why don't we use these systems to repair the ozone layer? Oh thats right, global warming is a lie so why pretend to fix a problem we didnt cause.
