- To filter impurities — use a two-step bath filter like the CuZn Bath Filter
- To neutralize chlorine and chloramines — add Vitamin C tablets or Vitamin C powder directly to your bathwater
Typically, 60% of the chlorine that most people absorb daily comes from showering or bathing in chlorinated water. Chlorine damages your hair and skin. Bath water also contains things like heavy metals and VOCs (volitive organic compounds). Ideally, all these things should all be filtered out.
Filtering bath water is a similar process to filtering shower water, If you have a shower head incorporated in your bath you can use my recommend shower filter ( Sprite Shower Filter), and use your shower to fill your bath. This means you only need one set of filter for both shower and bath.
Otherwise, I recommend using a dedicated bath filter like the CuZn Bath Filter. This bath filter has a 2-step filtration process — it features both KDF (Kinetic Degradation Fluxion) filtration (good for removing heavy metals) and Granular Activated Carbon filtration (good for removing sediment, chlorine and radon).
The Crystal Quest Bath Filter available from Amazon for around $50.
Vitamin C Tablets or Powder
Vitamin C tablets or Vitamin C powder will remove 99% of free chlorine and 99% of chloramines from bath water. Chloramine or NH2Cl (a combination of chlorine and ammonia) is now commonly being used in place of chlorine for disinfection, but chloramine is not easily removed from water. However, Vitamin C can neutralize 99% of the chloramines from water. To back this up, the San Francisco Public Utilities Commission now states on their website that only Vitamin C can be used to remove chlormaines from municipal water. Here is the quote from the Commission:
Vitamin C (ascorbic acid) has recently been included in AWWA Standard (AWWA, 2005b) as one of the methods for dechlorination of disinfected water mains. SFPUC and other utilities have used Vitamin C for dechlorination prior to environmental discharges of chlorinated and chloraminated water. Since ascorbic acid is weakly acidic, the pH of water may decrease slightly (Tikkanen et al., 2001). Ascorbic acid has been used for a long time as one of the dechlorinating agents for preservation of chlorinated or chloraminated water samples for laboratory analysis.
The full document can be found here.
Vitamin C tablets are slight more convenient since the some in measured amounts (tablets) and they also “fizz” to release the Vitamin C. However, Vitamin C powder is quite a bit less expensive overall.

Is there a filter product that will fit a waterfall faucet for a jacuzzi bathtub? It is about 6 inches in length.
you’re paying to take out the b******* they put in your water the chloramines and they give you absorbing acid which is a manmade synthetic deadly version of the real vitamin C this definitely keeps you in theMEDICAL system .
somebody has thought long and hard about taking out one poisoning give you another. this FAKE PLASTIC VITAMIN C destroys the beneficial bacteria in your body that is needed to keep down the bad bacteria that enters it .the only way to get clean water as if it is distilled and they’ll lie to you on that one and tell you how it leaches minerals from your body, part of that’s true it leaches “inorganic minerals” those that are The Deadly Ones that don’t belong in the first place .it does not and I repeat does not remove any of your nutrients minerals from the body only the toxic disease and helps with heavy metals. do your own research .there’s a war on your health and the pharmaceutical companies are racking up they are the ones help pushing for you to buy absorbic acid and you’ll be back for more medication because this is going to make your body very sick. Their medication it’s poison it’s time to wake up….. Latin for Pharmaceutical means poison Latin for pharmacist in sorcery. Do you see a problem here
It is very important to really start doing our homework on everything that the Industry Source telling us we have been lied to for a long time we are one of the sickest countries in the world you need to know all your food ingredients and all the ingredients for anything that touches your body it needs to be simple and natural ingredients if it is not it is overwhelming on the body we’re already in a sad shape and we keep subjecting ourselves to more more of their poisons. In the medical field Hospital uses distilled water dialysis patients that’s because it removes impurities and it doesn’t harm the patient so when they lie to you and tell you at leeches minerals know that you have this information good luck.
Your rant makes no sense. You are not ingesting ascorbic acid in the bath, and nobody is going to bathe in distilled water.
While he certainly could have been more concise in what he was saying, I believe Rhutch is concerned that it may be dangerous to ABSORB synthetic vitamin c, in any way. Besides absorbing things (chemicals, pollutants, toxins, germs , etc) through ingestion of say, contaminated foods or drinks, your skin is porous , which means you can absorb things through it as well. The difference of course is things you eat go through your digestive track first and things you absorb via skin contact go directly into your blood stream. Now, whether synthetic Vitamin C (or any synthetic vitamins) is dangerous in any way , whichever way it gets into your body -I do not personally know so you’ll have to do your own research on that one.
As for bathing in distilled water, you never know what someone might do. I personally think it makes much more sense to buy a filter that stays on the tub faucet than lugging a container of any type of water to the tub constantly, and I don’t know of any bath filters that use distillation myself. But if they had one I personally wouldn’t buy it since I’m not comfortable using DW with so much conflicting information on it. But to each their own.
It might be interesting to know the effects bathing in a modest amount of ascorbic acid. However, I’m pretty sure bathing in chlorine is more detrimental.
In regards to distillation — I have a smaller distiller in my house, and it takes about 30 minutes to distill one cup of water. It also uses a lot of energy to do this.
Master i agree Rhuch. I dont bath in distiller water as i have a whole house water filtration system (whf) – but absorbic acid isnt as good as vitamin c from fruit. There’s other factors that make vit c useful in the body and theyre missing from the synthetic verison. I dont know about vit C if it is absorbable through skin but it probably is. Vitamin B12 is absorbed through skin on contact with soil- thats why so many are deficient in b12 because people dont grow thier own food anymore.
Since installing the w.h.f my baths no longer cause my heart to race or keep me up all night. There is no smell of chlorine on my skin and my skin is softer. Wrinkles around my neck have started to fade.
The crap in our water is bad news and distilled water is beneficial- it just has no flavor as all the oxygen is also removed. Thats why i switched to whf system with chemical scrubbers.
Do these filters work with well water?
Yes they should remove a limited amout of sediment and other contaminants.
Is it recommended to use just the Vitamin C in lieu of a filter? That would be easy and cost effective.
Yes, if you just want to remove chloramines and chlorine.
Hello. I came across your article and saw that you recommend the ‘Crystal Quest Filter’ for showers etc. I actually purchased this filter about a year ago, and had issues with particles from the filter floating in my daughter’s bath water. I ran water through the filter as the instructions indicated several times which wasted gallons of water, and particles were still present. When I called the company, I was told that this was ‘normal’, and should diminish after a few uses. That was not entirely true. Another oddity I experienced with this filter was discoloration after a week of it being in my home turning a yellowish-green color. I have since returned it, and have yet to find another filter for our showers/bath.
Any idea why this occurred? What other filters would you recommend? My family and I will be moving to NC soon and I’d like to purchase a few filters for our new home. I’ve come across some informative and incriminating articles/information about the water being seriously polluted in various parts of NC especially at Camp Lejeune and surrounding areas which concerns me. If you or your readers have any other recommendations for shower filters, would you kindly share.
This is great info. I’ve always used my filtered shower head to fill the bath but will have to give this a try. Thanks!
How many mg of Vit C do you recommend per tub full? I found some powder that has 1250 mg per 1/4 tsp. knowing an amount in milligrams would be helpful. Thanks for your great reviews!
I put a few tablespoons in per bath.
Apparently the exact amount is 1 milligram per liter of chlorine per 100 gallons of water (see https://www.fs.fed.us/t-d/pubs/html/05231301/05231301.html). This is tricky though, because you probably don’t have info on the amount of chlorine in your water.
How much vitamin c powder to each bath will make it safe?
About one tablespoon is all that is needed.
