A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!
Guidelines:
Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!
Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.
Videos links are not allowed as post titles, but you may use them in a text post.
A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:
- The item must be made with sustainable or recycled materials.
- If electronic in some way, the item must be open-source.
- The item must be user-serviceable (if applicable).
- You cannot be a large corporation.
- The post must be clearly marked with a [Self Promotion] tag in your title.

I don't know if these filters for permanent installation have some techology to prevent this, but the smaller jug-style water filters increase bacteria growth if you don't regularly exchange them. I think for a part with such a huge internal surface that is permanently wet, this is really hard to avoid unless it has a special desinfection mechanism.

For short-term use while hiking I use water filters by Sawyer or Katadyn so far without problems. But I rinse them with chlorine and vinegar before I put them away for storage.
I know somebody with a full house filter, and it uses UV to reduce bacterial growth.
