Easy to install, water is perfectly tasteless
Very easy to install and the water tastes great, which is no taste at all. It came with a number of fittings, which were very useful and plenty of tubing. I highly recommend it and would definitely buy it again.

Amazing product and service! What we like about the product: - Easy to install (everything you need to add on to your existing sink setup is included, just need a few tools) - included faucet looks great by the way! - Doesn't take as much space as the bulkier RO systems (which we were originally shopping for, but subsequently found out we'd be ok with the US31) - Water tastes great! - Reunited with long-lost counter space (we used to have the huge Brita container sitting on the counter) - No more Brita refills, and waiting for the water to filter. Now, it's instant on. - Break-even in terms of Brita filters is probably going to be 1 year or so. So as long as the iSpring system works out past that, we're ahead. What gave us some hesitation right after installation: - There were a lot of air bubbles for the first week or so (as in, the water would be opaque white) - to our guests, it didn't look like "safe water". Turns out that I might have over-tightened the filter covers during the install (oops) - air trapped in the filters didn't have anywhere to escape. Clear water after a week though. All good! - Only noticed after using for a week that there was a little "play" at the base of the faucet. Was going to try and open it up to tighten the bolt, but decided to reach out to their CSR. Which brings us to what we liked about their CSR: Nick replied almost right away and mentioned that there was no need to adventure down that path since the faucet is covered under a 3-yr warranty. We were pleasantly surprised with a brand new replacement less than a week later. All in all, we're quite satisfied with the iSpring US31. And nope, we didn't even get paid to write this up, in case you're wondering... lol

同類の浄水器を長年使っていメーカーにフィルター交換依頼してましたがましたが、1年前にispringのシステムに変更、自分でフィルターを購入し交換できるので良いですね 逆浸透膜につなげる前にバケツ6杯くらいフラッシングします
