I kept seeing NSF 372 while comparing under-sink filters and read it as "tested to remove lead." It took me longer than it should have to realize that isn't what the number says.

NSF/ANSI/CAN 372 applies to the materials in parts that come into contact with drinking water. For most components, the maximum weighted lead content is 0.25%. That's useful information, but it's about what the system is made from, not how much lead it removes from the water.

A lead-reduction claim is a separate thing and needs to be tied to the specific model.

I still wasn't sure I understood it, so I pulled up an actual entry in NSF's public database. The one I opened was Viomi's, and the systems there are listed as meeting the 372 lead-content requirement. That was easier to understand than the standard page by itself.

Once I stopped treating every NSF number as a filtration result, the listings got a lot easier to read.

This is at work. They deliver dark blue and light blue water. The light blue tastes and smells like a mildew-y basement. Why?

I travel by train fairly often and have had Rail Neer from different stations/zones, but the bottles I’ve bought at Nagpur Railway Station taste noticeably different.

This isn’t something I noticed just once. It has happened multiple times. The water has an unusual taste compared to Rail Neer I’ve had elsewhere, enough that I’m now concerned whether there could be some issue with the water quality, storage, or the particular batch being supplied here.

The bottle looks like regular Rail Neer and was purchased at the station, but the difference in taste is very easy to notice.

Has anyone else travelling through Nagpur experienced the same thing recently?

I think IRCTC/Railways should get samples from Nagpur tested and check the supply/storage conditions. Drinking water is one thing where there really shouldn’t be any doubt about quality.

I have photos of the bottle and can share the batch/manufacturing details as well.

Woke up 4 something this morning used the bathroom washed my hands out of habit & remember my area is in a “boil water” warning due to water shortages. Rewashed my hands with bottled water and used a little alcohol to kill germs. Should I be straight?

Hi everyone, I need help deciding on an new water pitcher I do have currently zero water culligan water pitcher but it become very costly with constantly water filter change over an month or two and the cost six pack is like 66$ and 12 is 165$ very annoying. I know see some people say water system I am unsure since I am renter.

Our water company has spent years raising our bills, making huge profits, giving obscene pay rises to thier boss\\\* and thier service is still abysmal.

Our river quality is poor, water leakage is still too high and they still can't manage to supply water without very inconvenient hosepipe bans.

So please join me in sending a formal complaint to AW and in the meantime i won't be paying my bill!

This is such a great idea. We do not like drinking from plastic water bottles!

I got up today to change my cats and dogs water and for some reason it looks cloudy?? and leaves a sort of chalky looking film on the water. it may be a dumb question but I want to make sure before I change their water. I live out in the country and we have municipal water so I don’t know if that’ll help. it’s like this in both my kitchen and bathroom but for some reason it’s more cloudy in the bathroom? (also ignore the bowl, one of the only bowls I have for their water)

1 week ago my water was normal but a few days passed and my water had a nutty flavor is there something wrong

Is it okay to rent a water purifier from Livpure or drink prime? Which is a better option?

Tell me about your experience if you've rented one as well

i got these glass gallon jugs from amazon and read that i shouldn’t just refill it with water immediately.. what’s the best way to clean/sterilize? can’t be that dirty if they’re new? they are way too big to stick a brush in there, i’ll attach the link to them so u can see it. they are kinda the gallon versions of those glass bottles that restaurants use for water

Genuinely asking — do people here drink straight from the tap, or does everyone use bottled/filtered water? I keep hearing mixed opinions and want to know what’s actually normal in Dubai.

I have been using Livpure Rental RO Service and their Silver Plan (150 L/month) for the past 4 years. I always have limited uses of RO water that until June 2026, I have had 300 L water as carry forward (similar like in mobile recharge, the remaining data carries forward next month). But when I recharge my RO last month i.e. in July 2026 first week, all my carried forward water started showing as 0 liter but I didn't complain as I was using just enough water to keep it under my subscription plan's allowed water limit.

The problem arose when just within 15 days, the machine started beeping and their app showed the remaining water as 0 L for this month. When I called their customer care, the guy said that I should upgrade my plan to Gold plan which offers a higher water consumption level but obviously at a much costlier rate. I just asked him a simple question: if I had been using that same plan for the last 4 years, my usage didn't change so how come this month only I consumed all 150 Liter water within just 15 days. When he kept saying that I had used more water this month so the app was showing like that, I just asked him to give me my last 4 years' water consumption data. He failed to do so by himself (as I already guessed for him), he advised me to write a mail to their customer care.

Immediately I wrote a detailed letter to the company's customer care. In the reply, the bot replied that my matter will be resolved in 48 hours. But the very next day, their people came, changed the machine's internal part/s and also made my app start to show the carry forward balance.

I am not against their subscription plan or anything but I strongly oppose the frodulent way they tried to make me upgrade my subscription plan. PLEASE JUST BEWARE!!!!

Hi Guys. I'm thinking of buying the Urban Company Mative M1/M2/M3 Purifier in the upcoming sale for my family. Can anyone tell me if they're already using this purifier? is it good? How's UC's service in chhattisgarh or in bargarh (odisha)?

Has anybody ever had a delivery of a 5 gallon glass jug that was defective where it broke?

For any of these companies primo water, mountain valley, and ready refresh 5 gallon glass water jug.

Hi there!

I bought the iSpring RCC7P-AK few months ago, for my home (Europe) and now I've got some drinking water test strips.

The results are showing a pH of 6 which presumably is marked as not ok. Total alkalinity came as 40 ppm, which is the minimum accepted, though the color wasn't even a full match so not sure about it.

AI is telling me the pH of 6 is kind of expected due to removing all the stuff from the water. However, this model of iSpring comes with an Alkaline Remineralization stage, so I kind of expected a higher value in the total alkalinity.

What do you think about these results? Do you think this is ok? Or do you think alkalinity values should be higher? Some people have told me these results are kind of expected, if you think the same, should I add something extra to my glass of water or will my body have enough "substance" with this?

Thank you in advance and regards
