Style Name: Shower Filter
Akin to most Amazon products with multiple reviews, there's something to be gleaned both from the positive AND negative feedback. This is certainly one of thosse products.

First things first: the Aquasana Shower Filter does what it promises. Expect noticeably cleaner and fresher water immediately after installation. I've used this in two different states over a 1.5 year-period. In both instances, the natural odor of the local tap water disappeared completely from my shower after installing this filter, likewise the water gunk ring that used to form after a week or two without it.

Related, this is one wonderful showerhead. I'm amazed with all of the filtration going on (alluded to below), such powerful pressure is produced. The multiple setting showerhead is likewise quite user-friendly, rarely -- once every 8-10 months -- requiring a moderate pore cleaning.

The Aquasana Shower Filter, however, is not perfect. This is one expensive solution to shower filtration. Ditto on filters which cost upwards of $35 (minus shipping), only available online (in most instances). It also weighs a ton + is enormous; if you have old or fragile plumbing, this is NOT the filter for you. Related, shower plumbing with minimal distance between the wall and the location of the shower head (<8 inches) might encounter problems with spacing.

Installation is likewise frustrating, requiring trial and error beyond description (for a moderate DIY'er). Getting the filter on without leaking plus the shower head firmly secure to the plumbing requires sufficient patience. Based on feedback from several reviewers, special caution should also be taken not to overtighten the filters to the shower head (to avoid housing unit cracking).

Style Name: Shower Filter
My husband is allergic to chlorine, so a shower filter is an absolute necessity. We've probably tried every filter that the home supply stores carry -- and this one makes all of those look like toy equipment.

It's not that the filters you get at Home Depot don't work. They do; they're certainly an improvement over the hard water we have, not to mention clearing out the chlorine. The thing is, they don't last long. The filters don't last three months, and we've never had the gizmo itself survive for more than a year. Usually, they broke in a dramatic manner, spraying the entire bathroom as they cracked with a loud bang. Depending on the design, they were also awkward to install, especially if you have a non-mundane shower head.

We've had the Aquasana for six months, and I've just bought the first replacement filter for it. This is definitely a significant improvement over those "basic" filters, and it's worth the extra money. The filtering is MUCH better -- I can tell the difference in that "I just feel cleaner" way -- and the filter lasts twice as long. It wasn't a bad installation, either. If you go to the company's Web site, you can also sign up for the filters to be auto-shipped to you, which is a distinct time savings.

Yes, this one costs a little more than the "basic" units you'll find at Lowe's or Home Depot. And it's definitely worth the expense.

Style Name: Shower Filter & Wand Verified Purchase
I read the reviews before buying and my experience is pretty consistent with many of the comments made.

The shower wand.
I have always installed shower wands in every residence our family has lived in, and really am glad I paid the extra $14 and bought this filter with the wand! Like most, this wand is continuously adjustable from spray to three pulsing/massaging streams. I cannot comment on the massage setting as no one in my family has ever preferred that setting. However, the spray is exceptional! Most shower wands choke back the water flow as you adjust them to the spray setting, but this one maintains a good high volume of water flow!
The pocket the wand nests in has a contour to match the (non-circular) shape of the wand. This keeps the wand locked in place. In the past, I've been aggravated when the wand would rotate left or right in the bracket if the hose got bumped.

This is why this product gets 4 stars instead of 5. As mentioned in other reviews, the hose ends were troublesome. First I had a leak at the "filter end" of the hose. Even though I used a strap wrench to tighten this connection well past finger tight, it continued to leak, so I installed the old hose from the wand I was removing. Finger tightening the old hose gave a good seal at this joint, but the old hose fitting did not seat properly on the wand end. Here, I found adding an extra washer (supplied for use with the new hose) caused the hose end to be properly captured without leaking. For what should be a pretty simple task, this was a bit of a pain, and what should have been a 5 minute job went to 25-30 minutes (to dig out & put away the strap wrench and test for leaks until the leaks were gone)!
Everything else went together as it should have.

Length: 1:50 Mins
The filter works as promised and it removes chlorine and softens the water, leaving your skin softer after showering. I like what it does, however, there are a couple things I'm not too happy about:

The filter was easy to mount, however, although I used Teflon tape, it still leaks on the filter end of the hose. There are many other complaints about this very same issue.

Another complaint I have is the limited angle of the shower head, which cannot be adjusted. My solution was to rotate the whole assembly so that the shower head points down and the filter is at an angle instead of perpendicular to the ground.
