I usually buy water, but it's inconvenient and I don’t like the way a large bottle with a pump looks in the kitchen. I’m thinking about a filter, what do you recommend if I like to drink water and am sensitive to odors? And so that it is not visible and takes up as little space as possible.

I’m sensitive to the taste and smell of water, so I understand you. Among bottled water, I even have a division into tasty and not so tasty)). The filters are different, the degree of purification is at least different. In your case, you can install a filter in the refrigerator or under the sink. I use the same company and regularly change water filter cartridge https://filterway.com/replacement-filter-cartridges/. I don’t smell chlorine or other odors in this water.

That's exactly why I would like to test my water. We don't say that it's not very good if there is a lot of lead in your water and it can affect your health.

Well, I agree with you that you need to test your water periodically. Even if you change the filter, because it's not very good for your health. I came across this once, I think it was here. These sticks are designed to take a sample from the water, or I guess not just from the water. Any surface that you can swab. You can test it for lead. I think you're doing the right thing, so I decided to do it.
