Aquasana AQ-4100 Deluxe Shower Water Filter System

Today, we’re taking a more in-depth look into the Aquasana AQ-4100 shower filter, a filter that you mount in your shower, on the pre-existing base. Lately, there has been a lot of talk about pollution and issues in the environment. Many scientists and healthcare professionals have discussed the idea of the toxins in our water.

Some of the toxins that could possibly be in your water are bacteria, viruses, cysts, heavy metals, and pharmaceutical toxins. These get in your water in many different ways, including through the soil and the plumbing. Since we drink so much water daily, it makes a lot of our body percentage. Do you want that percentage to be filled with things that could potentially harm your health? We don’t think so.

Let’s go over the features of this water filtering system, the pros, and the cons, and then see whether this product is the right one for you or whether you should take a look at something else.

Filtering Showerhead

Aquasana AQ-4100 isn’t as conventional as other water filters. It’s not a regular water filter that you put on your faucet or under your sink. It’s a shower head filter that you put in your bathroom. Many people don’t think about the fact that e don’t use water only for drinking, but also for many other things, such as showering and washing our face.

Since our skin absorbs moisture, we absorb the toxins from the water as well. That’s why you should get a showerhead filter, one that will make sure you don’t get covered with harmful contaminants during each shower.

The Aquasana shower filter is actually pretty similar to a regular showerhead. It can be rotated slightly, and it gives you an experience related to the regular one. The only issue is the fact that you cannot take it in your hand and “freestyle “your showering session.

Better Skin and Hair

Filtered water will help your skin glow, help your hair rejuvenate, and improve your nails become stronger. Toxins have a significant impact on our body, especially on the surface layer. That’s why filtered water is essential – no chlorine to further dry out or “poison “your skin-

You will also start noticing that your skincare products and other body care products absorb much better and that you don’t have to use as much product to get the same results as you used to before you started to use the filter.

NSF Certified

Whenever buying a water filter, it’s of extreme importance to see whether the filter has the NSF certification or not. If the National Sanitation Foundation certifies the filter, this means that there has been researching done on the efficiency of the filtering system inside of the product.

It’s not an “I told you “type of a situation because there’s actual proof of the filter removing chlorine, lead, iron, and heavy metals. Most of the NSF certified filters also leave behind a specific pH that’s required for the body’s natural balance.

This means you won’t be stripped of your magnesium and calcium, the essential minerals we need to get from water.

The Filtration

Aquasana AQ-4100 filter has coconut shell carbon layers, which are eco-friendly and do a great job both with organic and inorganic compounds. The natural shedding of the filter layers will prevent any clogging and other issues, while it lets through just the right amount of water to balance the pressure that’s safe for your plumbing. 

The filtration itself should last you 10 000 gallons before you need to replace the filter. This means that if you use a gallon a day, you can use this filter for about 27 years. Well, that’s not realistic. If you use 5 gallons daily, you can use the screen for about six years! Don’t believe anyone that gives you an exact timeframe, though, because the lifetime of a filter heavily depends on the way you use it. 

Having a water filter is also very budget-friendly, as the slightly lower pressure can lead to you using a bit less water each day, which adds up when you look at the use long-term.

There is also a layer of filtration made from a blend of copper and zinc. This layer is supposed to remove any chlorine from your water further and take care of the pH of the water.

Easy Installation

If you’re worried that you’re going to have to pay a plumber to install the showerhead, you don’t have to be. There are only four steps of installation that you have to go through, and this won’t take much longer than half an hour for someone who is not that experienced. 

You don’t actually do anything with the plumbing. You just have to adjust the showerhead filter on the base that your usual showerhead is at. First, you remove the old showerhead, then you install the filter without the new showerhead, then you flush the filter, and you attach the new showerhead back on top.

Massage Settings

It’s always nice to have some extra functions in a product that’s made specifically for something else. This showerhead actually has an option to provide you with massage features – specific patterns of letting the water out to make your shower more relaxing.

The Numbers

Let’s go over the numbers once again. This filter removes about 90% of the chlorine in your water, it can go through about 10 000 gallons of filtering before you replace it. You’re also getting a one year warranty and certificates from the NSF under the classification number 42 and 61. 

The flowrate you can expect from it is 2.5 gallons per minute, which should do a pretty good job to mimic your regular showerhead.


  • one year warranty
  • pretty good lifetime
  • clean design
  • eco-friendly filtering


  • not budget-friendly for beginners
  • some people noticed the housing is a bit flimsy


Customer reviews usually repeat the same few thoughts when it comes to this filter – great filtring, great looks, but a bit too pricey for what it does. The reason why people still get this filter over the other ones is that Aquasana has pretty good customer service, and they tend to resolve issues that are presented to them by their customers.

Overall, this is an excellent filter, and if you’re ready to pay the price, you should go for it. If you’re still skeptical, we suggest you check our other reviews of showerhead filters and decide whether another one is better.
