3M Aqua-Pure Whole House Sanitary Quick Change Water Filter System AP904, Reduces Sediment, Chlorine Taste and Odor, and Scale, Heavy Duty, 100,000 Gallon

I own this and got it installed about 3 weeks ago.I have city water. I did testing beforehand and saw that my tap water was high in alkalinity and calcium. I had a plumber install the full version of this filter that includes the descaler. Plumber had to cut open a hole in my townhouse garage wall. $1,400 for plumber. Great result though with very nice looking piping, very discreet and right up against the wall. The water was immediately noticeably better, after a 5-10 minute flush of the filter. Even though it is just a water conditioner/descaler rather than a softener, it has a significant softening effect. The chrome and glass in my bathrooms have already improved a lot in just a few weeks.I would say the water smells, tastes, and feels 80% better. Super easy to change the filter, so no reason this won't work perfectly for 20+ years. They could possibly even upgrade the replacement filter cartridge design in the future.It did reduce my water pressure 5-10%, not enough to care, but that was probably partially due to the loop in piping my plumber had to make. It does seem like the water pressure has improved a little recently though, so it is possible the descaler has helped increase the diameter of the piping throughout the house by loosening up some of the lime buildup in the pipes.It is most noticeable when just washing your hands. The water has a slightly slippery feel like a water softener, although only about half as slippery. I think water any softer feeling than this would be overkill. My plumber said that his company usually rebrands a nearly identical water filter to this and charges over $1,100 for it, so this is a great deal comparatively.Hard to imagine really needing more filtration or softening than this. I wouldn't waste the water pressure or time or money on a prefilter for this if you have city water; just replace the filter every so often. Over the years, it probably pays for itself at least halfway due to the increased life you get from your water heater, dishwasher, clothes washer, toilets, faucets, and fridge.I rate the overall effect and quality of this product a 9 out of 10.I still use a Brita for my drinking water because I didn't want to just throw it out, and it seems like this filtered water going into your Brita makes your Brita filters last way longer if you still want to use that.

We purchased our new, last, forever home recently and we loved everything about it, except the water smelled horrible. We have always preferred well water, but we didn't remember the water smelling this bad when we inspected the home prior to closing. We tried the activated charcoal shower head filters, but they did very little, if anything and I was beginning to think this was never going to be mitigated. We looked at every method out there and this system looked like the best option, if it would work. The filter changing method is by far the best available, so we settled on the Aqua-Pure. I installed it with CPVC and added added a spin down sediment filter in front. It took about 3 hours to plumb. After finishing late that evening, we checked the shower for smell and it was still there, but not as bad. By the next day it was completely gone and has been that way since. We had to cycle all of the old water out of the water heater before the smell would subside. We have had clean, odor free water for a month now and I can't say enough good things about this product. We'll see how long the filter lasts, but I'm hopefully optimistic that we can get 6 months to a year before a change. Great price, great system, simple solution.Update: 2 1/2 months later and our water is still odorless. I see some low ratings for this product and I believe the premature filter changes are due to not using a sediment filter in front of the AquaPure system. I use a 50 micron spin down filter in front and I have to backwash weekly and swap the reusable filter monthly due to sediment buildup. If I didn't have the spin down in front, I would probably have plugged up the AquaPure by now. 3M CLEARLY RECOMMENDS using a sediment filter in front and I believe I will get the maximum longevity from the AquaPure as a result. When my spin down filter is clean, I have maximum water pressure from my well.Update - August 15th, 2021:We have now been using this filter for 5 months and we have learned much about our well. Our well is 480'+ deep and only has a flow rate of 3gpm. Our previous home had a well not as deep but it had better water flow. We found out the hard way that you can't run a slip and slide for the grandkids without putting a strain on the well. When it gets overused, we see a lot of algae show up in our spin down filter, that is in front of our AquaPure filter. The algae clogs the spin down filter, which is a 50 micron filter, so we have to backwash it multiple times daily to restore optimal water pressure in our home. Our water without filtering is extremely smelly, like bad eggs, but the Aquapure filter removes 100% of the odor. I have seen a lot of people complain that the filter doesn't last long, but I am convinced that is because those individuals didn't use a prefilter on their system. The directions strongly recommend having a pre-filter in front of the Aquapure and I suggest a 50 micron spin down, because we have been going strong for 5 months with our Aquapure and I am amazed it is able to remove every bit of the odor. I believe we will get close to 12 months use from it. I am very pleased with our iSpring 50 micron spin down filter, as well. I will update when it becomes necessary to change the AquaPure. I would give it 6 stars if possible.One additional note. The AP917HD-S, AP917HD and AP910R all are interchangeable with the AquaPure quick change system. I purchased replacement filters, so I would have them when I needed a replacement. I tried the AP910R, because it still says in the description that it had activated carbon filter, but that is not true. The AP910R DOES NOT contain any activated carbon, whereas the AP917HD-S & AP917HD do. The AP910R did not remove any odor from my water, so don't make the same mistake and buy the AP902 system or AP910R replacement filter if you are trying to remove bad odor from your water.

3M products are the best. We’ve had a crack in the in our deep well casing causing red silt to get into the water. We’ve tried paper filters and whole house filter with back flushing and nothing worked that long. Changing out paper filters was tedious since there were 4 inline. Every month they had to be changed and got water everywhere. This filtration system works very well, keeps the silt out, just clean water. No water spills when replacing the filter, just unlock, twist and put a new filter back on. For us, it’s lasts 6 months but it’s worth it. Paper filters aren’t that cheap either so the cost balances out over time. I recommend to anyone especially if you have silt in your well water. Everything 3M makes is top notch, use their filter, not a cheaper substitute.

I absolutely love the 3M Aqua-Pure Whole House Water Filter! The quick change filter design is amazing and makes maintenance a breeze. The genuine replacement filter AP917HD works wonders in reducing chlorine, taste, odor, sediment, dirt, and rust. I highly recommend this system for anyone looking to enjoy clean and great-tasting water throughout their home.
