iSpring US31 Classic 3-Stage Under Sink Water Filtration System for Drinking, Tankless, High Capacity, Sediment + GAC + CTO (Newest Version)

I have a pond and to reduce the heavy metals when topping up I use these in my filtration , does the job good quality and the value for money means I can change my filters more often than recommended , easy to use quick delivery 😀😀😀

I'm really pleased with it! After a few days for the tiny bubbles (which made the water look cloudly at first) the water is noticeably improved over our tap water supply and it's now my go-to source for drinking water. No more expensive bottled water, no more plastic waste! So good I bought a second one for our office. There was a small broken connector when it arrived but I'm still giving 5 stars as the customer service was excellent and they got me a replacement part very quickly

No problems with my first set, no problems with my second set all works well. Glass on the left old filter water, glass on the right new filtered water. Without send ending the water to a laboratory for testing i cant say 100% whats been cleaned out. But the orange specs i think is iorn and the black filter who knows but there is a difference with using filters.

In very simple terms these cartridges are an excellent choice. They were an absolutely perfect replacement for my existing set with full fitting included just in case you need it. Will buy again.

Great value

Great pice of kit work very well

Ordered many times now, never had a problem with this product. Good RO system filters replacement. Value for money

I purchased these as a trial to see if they would fit my AquaFilter home filtration unit. I can confirm they fit perfectly and in saving ££ in the process ;) I have setup a 3 monthly subscription to keep them coming without the need to chase the next deal. Very happy customer :)

Filters work as expected, they last about 6 months, easy to replace, water flow is free and fast. Last stage makes the water taste better and chemical free. Noise levels are zero. Great replacement filter set. I bought two more replacement sets just to simplify my process, after getting this the first time.

Ho acquistato questo set di cartucce iSpring F3 per il mio impianto a 3 stadi e sono rimasto davvero soddisfatto. Il kit arriva completo di tutte le cartucce necessarie per 6 mesi di filtrazione: ✔️ Filtro a sedimenti da 5 micron per rimuovere sabbia, polvere e impurità ✔️ Filtro a carbone GAC contro odori, cloro e sapori sgradevoli ✔️ Filtro CTO a carbone compattato per migliorare ulteriormente il gusto dell’acqua Installazione semplicissima, basta svitare i bicchieri dei filtri e sostituirli. Tutto perfettamente compatibile con i sistemi standard da 10” (nel mio caso un impianto iSpring, ma vanno bene anche su altri modelli). Le istruzioni sono chiare, anche chi non è esperto riesce senza problemi. Dopo il cambio si nota subito la differenza: ✅ L’acqua ha un sapore molto più pulito e fresco ✅ Spariti i cattivi odori ✅ Si vede la trasparenza dell’acqua migliorata ✅ Nessuna perdita o problema di compatibilità Inoltre, rispetto ad altri filtri economici provati in passato, questi sono costruiti con materiali di qualità, si sente la differenza nella durata e nell’efficienza della filtrazione. Ottimo rapporto qualità-prezzo, considerando che si tratta di un kit completo per 6 mesi. Non ha senso risparmiare sulla salute o rischiare con filtri scadenti. Consigliato senza dubbi a chi vuole garantire acqua sicura e di buona qualità in casa, risparmiando rispetto all’acquisto dei filtri singoli. Lo ricomprerò sicuramente per il prossimo cambio!

最初はちょっとフィルターの味したが、すごく設置しやすい、いい製品です

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
