      A:  Hello Juliez, Thank you for reaching out to us. The shower filter removes 5 microns. Please let us know if you have any further questions at 866-662-6885. Thank you, Aquasana Customer Support

        A:  Most amoeba are 250 to 750 microns in size. N. fowleri is microscopic: 8 micrometers to 1 5 micrometers in size, depending on its life stage and environment. By comparison, a hair is 40 to 50 micrometers wide.

          A:  Yes it does absolutely!!

          by|Nov 26, 2020

            A:  Yes, you can use your own shower head. The AQ-4100NSH is the correct model for individuals using their own shower head. Just remember the shower head needs to have the same 1/2 inch connection as standard shower heads and the ideal flow rate would be 2.5 gallons per minute. If your shower head processes more than a 2.5 gallon flow rate per minute, the quality of filtration may degrade slightly. Increasing the flow rate by changing the shower head reduces contact time with the media and will reduce the filtration quality. If you decrease the flow rate of the system by using a different shower head, or use a shower head with a shut-off switch, you may cause damage to the system and void your warranty.

              Still figuring it out
              Pros - I am pretty Impressed on how less I have to clean my shower due to soap scum and hard water build up. As for my skin I can’t really tell a difference. Cons- I dislike how big it is. My shower head has no room and I can no longer adjust it to spray down due to how long the filter is. Would be nice if it wasn’t right up against the shower head. Or if there was an adapter to add on. And it also leaves little black charcoal looking stuff in the shower. Maybe I got a bad filter I don’t know.

              Filter chorine but not TDS in water.
              The filter works ok. It seems to reduce about 30% of the chorine in the water after the filter installed and flushed for 15 minutes. The TDS did not change. TDS measured at 549ppm before and 552ppm after.

              Hello, TDS, or Total Dissolved Solids, is the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium. Please see the link below for additional details: https://www.aquasana.com/info/tds-meter-what-is-it-and-do-you-need-it-pd.html Based on the product that you're inquiring about, it is tested and certified to NSF/ANSI Standards to reduce more than 90% of chlorine in shower water.  For an accurate measurement of the performance of our system, you can purchase a water test kit at your local hardware store or Amazon. They range in price from $10 to $100+ USD. With the performance data sheet and the water test results in hand, you will have a more accurate depiction of our system's performance.  -Aquasana Customer Support

              Awesome
              Love it, only one suggestion - the outlet should be at a bigger angle upwards to adjust for customers own shower heads.

              Good filter, one flaw
              We like how the filter works and the shower flow is only slightly diminished. The one flaw is the exit spout is so short you can only use a small diameter shower head. I had to rig my own adapter to extend it about 1.5 inches in order to use our existing 8 inch diameter shower head. A little ugly but it works. Aquasana doesn't offer an adapter/extender.

              First of all to add this filter into the shower is very easy/to replace it also very easy. The first time I took a shower with this filter on,I saw a big difference on my skin,it’s softer/my hair doesn’t fall as much,very pleased with product,I tried other filters before this brand and doesn’t compare to this. Thanks aquasana.

              Chlorine smell gone! hair and skin feels clean now
              We live in an area with extremely hard water and a lot of chlorine smell. We never felt clean after showers. After installing the filter, the chlorine smell disappeared and water cleans the soap of very easily. Very satisfied with the performance of this aquasana filter.

              Well....
              I was concerned about my was pressure right after it was installed. And comparing it to my Brita pitcher, my water pressure will end up going down immensely as the filter collects more and more ick. I also don't see that it has made any difference with my hair or skin. It also didn't install easily with my dual shower head set.

              Did not work at all
              I got sent this aquasana and there is no way this thing could have worked the metal bar it was connected to was so loose it would squirt out no matter what waste of time.

              Hi Nicole, We are sorry to hear that your system was leaking. Based on the information provided, looks like the issue might be resolved by using plumbers tape which is advised to use when installing. However, we would love to further assist in ensuring the issue is resolved. We will have a member of our Customer Support Team reach out and assist.
