      Not how it works, sorry to tell you. In fact, putting the lid down means you are keeping those particles airborne for another 11 minutes or so due to increased pressure with the lid down.

        Do you have a source? I googled it and every site listed said you should close the lid. The only one that didn’t was the New York Post, which is a famously inaccurate and overly contrarian news source.

          People usually see the initial drop of visible particles to mean closing the lid is better but it just causes the mist to aerosol more into nano particles when the lid is closed. I don’t have the study itself handy at the moment, let me dig a bit more but I did find this article which was referencing similar findings. Let me try and find the paper itself though, but in the meantime here is a small except about the study from a site that was promoting the conference where it was presented at:

            The first line of that article supports putting the lid down…and so do subsequent statements…

            Research has found that flushing the toilet with the lid down could reduce airborne particles by as much as 50%

            The research found that putting the toilet lid down reduced the number of both visible and smaller droplets during and after flushing by 30-60%

            Lid down causes 30-60% reduction of droplets in the air but they stay in the air longer…

              Nice way to conviently omit the next fucking bit of the article like Google does 🙄

              However, use of the lid also increased the diameter and concentration of the bacteria in these droplets.

              It was also found that airborne microdroplets were detected for 16 minutes after flushing the toilet with the lid down, 11 minutes longer than when the toilet was flushed with the lid up. The researchers suggest that this could be due to particles being re-aerosolised from surfaces rather than being created by the turbulence of the toilet flushing. Alternatively, the researchers suggest that airborne particles could stick together, or agglomerate, which would cause them to remain airborne for longer.

              I.e droplets with more bacteria lingering around longer in the air and traveling further. The biggest risk with bacterial contamination is concentration, which this literally tells you is increased by putting down the lid as well as spreading further with a longer time airborne. But go on showing your lack of comprehension.

            Well, you might be doing fine so far. How about others who walk into your poop-plumes? Hygiene is not always only beneficial for yourself. Some easy to implement practises can go a long way. I think it’s a similar story to how we (should) regularly wash our hands, wash vegetables and fruits before eating and so on.

      Hate to break it to you, toilets aren’t airtight. The particles go right out the side and tend to last longer in the air when the lid is down. It’s creates a reduction in visible particles as it seems the lid causes bigger particles to form so ergo less “visible particles” but they are just bigger and last longer for some reason versus the smaller ones. As has been demonstrated by the Mythbusters and many other studies, the biggest factor is having proper ventilation otherwise your gonna find shit particles everywhere regardless of if you close the lid or not.

          For reducing visible particles, not the nano particles which have a higher concentration. Regardless it’s all kinda moot as neither produce levels of bacteria that could realistically get you sick unless you stick your face above the bowl or to the side openings by the lid while flushing and that person has an infecfion. Just wanted to clarify the science behind it.

            The highlighted section of that link reads as follows:

            The research found that putting the toilet lid down reduced the number of both visible and smaller droplets during and after flushing by 30-60%. However, use of the lid also increased the diameter and concentration of the bacteria in these droplets.

            The article doesn’t indicate whether the total bacteria contained in the now larger and more concentrated droplets is thought to be comparable to that contained in the full spray of open-lid droplets, which means a precise comparison isn’t available, so technically I guess it could go either way. However, common sense tells us that many of those microorganisms will either get stuck to the underside of the lid or fall back into the water, so it seems nearly impossible that closed-lid flushing could spray 100% of the microorganisms that open-lid flushing does, right? So if the best (seemingly unlikely) scenario for open-lid flushing is that maybe it only sprays the exact same number of farticles into the air, then what’s the appeal?

        That’s not making sense to me. Would you be willing to find your sources? Larger particles would not spend more time in the air as far as I know. It’s almost like you’re claiming it’s better to sneeze wild straight out everywhere instead of into your elbow, handkerchief, or tissue.

        But that applies to most commercial toilets with high flow rate. Most home toilets don’t do much more than let gravity do the work. There’s no aerosolized particles, just a few splashes or droplets that may escape

          Home toilets use the bowl filling up to create a siphon through the drain trap. For that to work your toilet must first raise the water level above the top of the trap to create the pressure with its weight to start the siphon. I.e with the lid closed you are forcing more air to compress in a smaller volume generating a pressure difference outside the bowl and internally. Leave the lid open and that volume of air goes directly into the room without much resistance creating less pressure in the bowl compared to the surrounding air in the room. Hence with the lid open the distance, the spray travels is lower as it has a lower velocity.

            That air pressure doesn’t mean anything without aerosolized particles. High rate commercial toilets create those particles and spew them out at like 6 ft/sec. Draining the tank into the bowl does not create much except maybe a few larger droplets once the drain takes most of the contents that can’t go as far, and that is mitigated by closing the lid.

            This would be a good experiment for Myth busters. I’d imagine that with the lid closed the increase in pressure would not be significant and the air particles would be accelerated more horizontally as opposed to vertically. This would, theoretically, cause them to accumulate more on surfaces below countertop level than above.

            But I have no data to support this hypothesis.

              How does flushing water create air pressure? Are you using a steam toilet? Are you acoustic?

              Did you just try to call me dumb when you don’t understand physics?

              Here’s a little science experiment and explanation for you:

              Water in a toilet bowl first rises as the flush begins before it over comes the pressure in the drain trap. Close the lid, more air is squeezed out the sides of the toilet for a moment as that happens, leave the lid up and you have a larger volume for the air to be offset in. Don’t believe me, flush the toilet with the lid down, wet a finger with water slightly and put it near the opening between the lid and the bowl, you will feel it cool down from the air escaping. Do the same now with the lid open and you will notice this effect less. Obviously do this with a clean toilet and wash your hands afterwards but you will notice the pressure difference in the beginning.

          Honestly don’t worry, as Mythbusters pointed out that neither are a health concern due to the low concentration relatively speaking and if anything it helps your immune system build up defenses against E coli and the like. Just know lid up during your flush means the sent lingers less. Then after the flush I would advise closing the lid to keep any lingering sent in the air of the toilet bowl and less likely to be disturbed by any airflow in the room. Just don’t like seeing misleading info spread around as honestly the science behind it is pretty interesting.

            I don’t want to step on your toes, so hopefully this doesn’t come across that way:

            You mentioned Myth Busters and an article from 2019 on microbiologyresearch.com in another comment .

            Let’s just say without further elaboration, that Myth Busters are not a solid scientific source.
            I couldn’t really find a paper from the article you linked in another comment. Just this: https://www.microbiologyresearch.org/content/journal/acmi/10.1099/acmi.fis2019.po0192

            I don’t know whether it’s an issue with the website, but currently I can’t see much else besides some text which sounds like an abstract. This makes it currently difficult to see this as a good source or estimate the quality of the work. Judging on this abstract alone, although it mentions that the time particles are detectable is about 10 minutes longer with the lid down, it also reports a 30 to 50 % decreased amount of particles. It also states a lack of research regarding smaller particles.

            As far as I can see we could safely say, that this issue, whether it’s better to keep the lid up or down, is still debated and a final verdict is still out:

            https://doi.org/10.1016/j.jhin.2011.08.010

            https://doi.org/10.1063/5.0040310

            https://doi.org/10.1063/5.0013318

            https://doi.org/10.1038/s41598-022-24686-5

            However, to me it seems that there are indications that a combination of proper ventilation and closing the lid might be better than an open lid.

          They also, for some reason, last about 11minutes longer in the air when closed. The studies are misleading because they say there are fewer visible particles, but the bacteria count remains the same.

          Although Mythbusters is not a peer reviewed scientific source, they do employ reasonable standards of experimentation.

          And the first source you posted is particularly interesting, with similar conclusions to what I remember from Mythbusters; that lids reduce the total number of particles found, but that the particles produced from lid use last longer and are larger. So a lid closed situation can;t really be said to be more hygienic.

          Unfortunately on a cursory skimming of the other articles none of them seem compare toilets with lid down to lid up, they all seem to look at lidless toilets only. Thus, they can;t really speak to the topic of lid use being more hygienic without the direct comparison.
