iSpring F3 NSF Certified 6-Month Prefilter Replacement Water Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems

Cheaper but give me same level of filtration. I will buy again.

Perfect replacement

Hi Guys:) 🤗 Nitrates in my well water, 😩. Have been using the I spring 6 stage R.O. system for the past 2 years. Really happy with the functionality of this unit. Recently, I got a positive test result for bacteria.... right after I replaced all new filters. I called customer support and spoke to Nick. So helpful and accommodating. Nick offered a resolution and support. Customer service is the key to any product. I am leaning towards purchasing another I spring 6 stage unit instead of sanitizing my current unit, and getting a different plumber to install it. Thanks again to Nick, for all your assistance. Way to go customer service!!!

Water tastes great, easy to install after looking at the video tutorials

I replaced the first set of filters on my RO system recently. The originals were about 14 months old. The sediment filter was a dark brown. Replacement is pretty easy, just put a towel down underneath and make sure you find your water filter wrench that came with the system. I thought my water still tasted great before the filter change and I still had adequate pressure, but I could notice a definite improvement in the taste after replacement.

Bought the filtration system here on Amazon to get rid of the chlorine and ammonia our co-op uses in their chloramine treatment. At times our water would be worse than pool water. Since installing the filtration system all of that has gone away. I have a buddy who oversees a different water system come over and test mine before and efter the filtration unit. Before, my chlorine and ammonia hover close to the maximum limits allowed, after the filters they are close to non-existent. So they do the job just fine. Water pressure drop through my system seems to vary from minimal drop to noticeable, depending on the filters installed. I change them every three months, and some set of filters just have a worse drop than others. It takes us a few days to get used to it then we really don't notice it unless I change to aset with less drop. Overall, not a deal breaker given the benefit of having largely chemical free water to was with and consume. Definitely a money saver after about a year vs buying drinking water. And I can't help but think the reduction in plastic we purchase has to help along the way.

We have well water in our home, and unfiltered it smells rather sulfur-ish. When we moved in the drinking water was "softened water" that was then filtered via a Reverse Osmosis system. RO is great for filtration, but we wanted to avoid the waste water associated with RO systems (3-4 gallons wasted for each 1 gallon of clean water produced). If you've ever made coffee with Reverse Osmosis water, then you also know how terrible that tastes! I bought a new 10" triple stage water filter housing and these filters. The housing came with 3 filters also (different brand) so I put those aside and use the these iSpring F3 filters. I bypassed the Water Softener and ran our drinking water through these filters. Water was fantastic. After 2 months, I noticed the sulfur smell was back. The water tasted fine, but I wasn't taking any chances, so I grabbed the no-name filters that came with the water filter housing, and it made no difference at all, the water still smelled terrible. I have 3 growing children and I don't mess with sketchy water, so I bought some bottled water and hit Amazon Prime. I ordered another set of the iSpring F3 filters and put them in the filter housing, ran the water to clear the lines and I am back to clean, smell-free water. I think the key filter here is the Carbon Block filter, as the no-name filter looked exactly like the carbon block from the outside, but when I looked inside the filter it was carbon in a mesh bag (sneaky sneaky). These filters are my #1 choice and I have budgeted for them every month and treat them as my "water bill", since I don't pay for my well water.

Our water taste great. We installed this in our last house. Then we tried another brand when we moved to our new house, but it left the water tasting flat and the parts where not as high quality as this one. We'll install another one if we ever move again.

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!

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 😀😀😀
