iSpring US31-NC 3-Stage Under Sink Water Filter System with Faucet, 1 Year

Have used these same filter sets for more than 8 years and always have at least one extra set on standby so it's easy to change out without waiting for an order to arrive. We have extremely hard water with a terrible taste and then the local water utility adds a terrible tasting chemical for purification. These filter out all of that and make the water much more tollerable. Also allows coffee and tea to have a better taste. And it saves on the waste and landfill contamination from plastic bottles. We've also found it to help with keeping the scale and lime out of the tea kettle for a longer period before it needs descaling. Value for money: 5 Stars Quality of water taste: 5 Stars Installation of filters: 5 Stars Durability: 5 Stars (We have gotten as much as 1 year out of a set before changing due to taste difference)

I’m very happy with this iSpring filter set. Installation was easy, and the filters fit perfectly in my standard reverse osmosis system. I like that the set includes a sediment filter and two carbon filters, making it a convenient and complete option for regular RO system maintenance. The filters feel well made, and after installing them, the water has a clean and pleasant taste. It’s also very convenient to get all three replacement filters in one package. So far, I’m very satisfied with my purchase and feel good quality for the price.

My well water has a slight smell, it goes away on its own if the water is sitting in a vessel, but I wanted a definitive clean. This 3 stage filter does the job well. The water is crystal clear. The installation was easy, took me less than an hour (I already had a hole in the countertop). All parts look and feel high quality. There are a lot of different filters on the market, I chose iSpring because they have a strong history of supporting their products with replacement filters. Here is how I rate: 5 Stars: Excellent product that meets all expectations. Any flaws are minimal and do not affect functionality or performance. 4 Stars: Very good product and worth buying. Performs well overall, with only minor issues. 3 Stars: Adequate product that functions as advertised but has noticeable shortcomings in quality, value, or features. 2 Stars: Functional but affected by major flaws or clear mismatches between the product and the claims made in the listing. 1 Star: Barely usable or completely unusable. May also include misleading or false claims in the description.

Doesn’t kill flow like a reverse osmosis system. Tastes fantastic.

Works great

I am very pleased with my new iSpring water filtration system. Installation was flawless and the system works beautifully. I was struggling to registering the product online so I called iSpring directly. I was pleasantly surprised by the prompt and friendly assistance I received from Matt. I've not often encountered such helpful customer service. Thank you Matt!

I owe this company a review. They went above and beyond to support a product they clearly stand behind far beyond the warranty period. I previous purchased one of their units that has since been updated. As that unit developed a leak, I reached out and spoke with Nick at iSpring. He was able to send me what I needed to get me back up an running at no cost to myself. I can't express my thanks any more than by leaving a simple Amazon review (not written by AI, so excuse any errors!). As to the product at hand, these are the standard set of three replacement filters you likely need to change out every 6 months or so. They work in conjunction to clean water as much as possible prior to reaching the reverse osmosis filter. I use a PPM meter to test and never have any problems - they work exactly as advertised. Thanks Nick!

I’ve been using this system for over two years and it’s definitely great value for money. Changing the filters is so easy. No regrets and definitely a good choice!

Fácil de instalar, la calidad, muy bien vienen completos y ayuda para filtrar el agua

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!
