Would the oxygen help sick people if you filled their room with plants?

I feel like I breath better in a room very full of plants, but just know that the plants can only convert the CO2 to oxygen that is present, and one person does not increase the CO2 a very significant amount. In other words, a single person is not going to add a ton of CO2 into the air over what is already present naturally in a large room, so the increase in oxygen is minimal. If you google increase in oxygen in a room with a plant or something like that, it might have the actual percent of increase or something more specific, which would be interesting.

Hydroponic farms do sometimes pump CO2 into the rooms to increase the growth of the plants.

I blow on my plants to give them more CO2, but it probably does nothing, because it is for one minute a few times a week, but I like to think the plant appreciates it.

I looked it up and it seems you would need 10 to 1000 plants per square meter in a room for it to really improve your air quality. Then there is the point of how many leaves does it have and its growth rate and also ventilation gets rid of most of the oxygen.

10 to 1000? That’s some range.

No, but it may brighten their day.

In clinical setting there are easier ways to fill the room with oxygen.

Seems like an airhead idea.

I dunno but I read this joke recently:

A friend of mine said a boot camp recruit he was with screwed up so much, eventually the drill took away his rifle and made him carry around a house plant. When the Senior Drill Instructor asked him why he was carrying around a plant he responded “The recruit has been instructed to carry this plant to replace the oxygen he’s been wasting.”

Nice to take care of a living thing, even if it is just plants. If they are well enough to water it and dote on the plants a little, it might help their mental state. II just wouldn’t gift it unless I knew they were ok taking care of it. People used to gift me plants and I would see it as an unwelcome chore when I was working all of the time and we traveled more. Now, I love my lemon tree that I have grown from a seedling.

@JLeslie I thought so too, but in other sites they said 7 trees. So maybe that’s what they meant. You would need plants as big as trees if you go less.

Plants live on CO2 so too much oxygen might kill them.
