Shower Head Filters VS. Whole House Filter Systems

Mr Water Geek ThinkingWhen buying a shower head filter need to remember that it is only a partial solution. You will only be able to get soft filtered water from that single water source.

This means that the water from your bathroom tap faucet, kitchen sink and the water you use in your appliances will still be contaminated.

Yes, there are higher costs, a slightly bigger commitment and maintenance but it is worth the investment.

If you want a permanent long lasting solution for filtered water in your whole home (not just shower) then a whole house filter is the way to go.

“Also, shower head filters are not very powerful. They simply can’t treat everything in your water so they may be ineffective for heavily contaminated water.”

Here are some more specific pros and cons of getting a whole water filter:Standalone Salt Free Aquasana

  1. I contacted the company that provided my reverse osmosis system to purchase a shower filter. The rep said they don’t sell them as they don’t work. He said it would be impossible for that much water to go through something that small and still be effective after a few days. He said they’re just a gimmick and the only reliable way to get clean shower water is through a whole house system. I was wondering what you think of shower filters generally. Are they useless after a few days?

    1. Hi Ann

      I actually agree with that sentiment especially when it comes to the cheaper shower head filters you get on places like Amazon.

      The AQ-4100 I review in this article actually has NSF certifications to prove it filters what it claims it does.

      However, it will not filter anything close to what a whole house filter can do, which is why I end the article recommending that people who want a serious treatment of their water get a whole house filter like the one from Aquasana.

      Stay hydrated,

  2. LOVE YOUR SITE. So helpful. What is the best Water Testing Kit? I am in Westchester, NY. (please do not use my name yet)

    1. Hi Laura

      I have not personally tried Aquabliss but I am becoming less and less convinced by that style of shower filter. Amazon is full of them and they all seem to have excellent reviews but the problem is that most people don’t use a water test kit to see if the filter actually works and typically give good reviews based on how easy it is to install and how good they look.

      I tried one of those types of shower filters (from Amazon) and my test kit showed that it made NO difference to the water quality so I threw it away and demanded a refund.

      All I would say is have a water test kit to make sure whatever you buy actually works.

      Best wishes,

  3. After more research I think you might disregard my last question because I am pretty sure the water here in the LA area uses Chloramines instead of Chlorine. The last report of 2017 said it had Chlorine but their website says they are switching to Chloramine and the entire city will be maybe even the state is moving to Chloramines. So all the filters listed and that I last mentioned do not seem to work for Choloramines although they would work for the other metals and VOCs and softening the water. So now Im looking at Vitamin C filters which seem to be the only option for filtering Chloramine. Are their any you would recommend?

    1. I know I’m a little late to reply, but the Sonaki worked great for us. However, we forgot to remove it from our last rental and I have to buy another one! Lame. But I’m looking at stacking another filtration system onto the Sonaki so we’re not just removing chloramine, but also the other contaminants. I’d heard rumors that there was a shower filter out there that did both, but I’m beginning to think it’s a unicorn.

      1. Hi Cece

        Glad you found the Sonaki inline worked well for you.

        There are other shower filters that promise to remove both chlorimaimes and contaminants like the pH Energize. But personally I’m very suspicious of the low price point and mixed reviews.

        You might want to try a more comprehensive shower filter like Aquasana Shower Filters. Although it doesn’t specifically target everything you want, it’s actually a proper filter so will treat your water. The cheap Chinese import shower filters that flood Amazon sound good in writing but don’t actually effectively treat water in my experience.

        If you decide to go with Aquasana then use coupon code: AQGEEK50, I believe this will give you free shipping (and 50% OFF more expensive products).

        Hope this helps,

    2. I found this interesting thread about the legality (or otherwise) of introducing chloramines into the UK drinking water supply. It seems they add ammonia AND chlorine to the water, the result is chloramines in the water, but they claim not to have introduced chloramine into the water!

  4. Hi thanks for the reply I am wondering if the Jonathon will be discontinued the website from the company doesn’t have anything. But you do think it filters more and better then the Aquasana? I am also looking at the Aquabliss 12 stage and wondering how you would compare to these?

    Another one I read about Aquaspace but no reviews yet would love to hear more about it if you ever get the chance to review it.

  5. Thank you! Have been thinking about this for about a week, and your article does a fantastic job of comparing the filters!

  6. Hi do you still think the Jonathan Product is the best shower filter at the moment? After looking at the EWG site and what contaminants are in my water and emailing the EWG for info they suggested a carbon block and reverse osmosis filter. I haven’t seen any reverse osmosis shower filters and I live in an apartment so cannot buy a whole house filter. Does the Jonathan Product have a carbon block filter in it?

    Thanks so much for your research and advice!

    1. Hi Cece

      Well done on having the foresight to get your water tested to see what you need the filter to do, most people don’t do that!
      From what I understand the Jonathan Product doesn’t have carbon filters but it does have carbonized coconut shells which is very similar to activated carbon filters.

      It can remove synthetic chemicals and toxic heavy metals and the result is pH balanced spring water.

      Hope this helps,
