As others have mentioned you will receive a years with of filters. So if you price the 7 filters individually this is a great value.Any experienced Aquarium owner is using a RO filter system for their water supply. As for the recommended filter changeschedule this will be determined by your Initial feed water test and monthly filtered water usage. In the 123filter iSpring owners manual that explain the feed water supply criteria as1. chlorine concentrations of 1.0 mg/L (ppm) or less.2. Feed water temperature to the unit must be no less than 40°F and no more than 100°F.3. Total dissolved solids (TDS) in feed water must be less than 750 mg/L (ppm).4. Feed water must have a pH between 4 and 8.5. Feed water must be completely free of iron, manganese or hydrogen sulfide.iSpring has additional filters if you have iron in the water supply.Changing the filters is pretty easy you just need to make sure to clean the filter housing with hot water and dish soap,dry, and a little tip from a scuba diver for the O-ring you can purchase a synthetic grease that is USDA rated H-I like "Super Lube"to coat the O-ring every filter change to allow a tighter seal. You will need plumbers PTFE thread seal tape for the filter that has thequick connect tube fittings screwed in both ends.I had to re-seat the quick connect tubing in the fittings a couple of times to stop it from leaking but this is Not unusual for anyone whohas done plumbing.

Just as a heads up, depending on the quality of your water, these filters may not be as effective as say replacing your osmosis membrane filter.While these filters do a good job of cleaning out the sediment, I found that the majority of the contaminants in our tap water were more effectively filtered by the osmosis membrane filter. Additionally, our tap water is at around 850 PPM, which is unusually high compared to the national average, so your results may vary.I would definitely buy these filters again. The only word of caution I would give is that your replacement schedule will vary depending on whats in your water (sediment, chlorine, etc).Use the 6 month and 1 year replacement schedule as a general baseline for these filters, but feel free to deviate from that schedule. Some people will have to replace these filters more often, and others less.It all depends on the quality of your water.
