In this guide, we share our top 5 best vitamin C shower filter picks of 2019, explore authentic Vitamin C shower filter reviews, the purported health benefits, and additional helpful information to help you decide if this is the right shower filter for you.
Vitamin C shower filters are popular in Korea and Japan. Similar to water ionizers, their popularity in Asia has overflowed into the Western world, and now we’re reaching for them in America to experience the health benefits of bathing in Vitamin C.
Of course, with all new health products in the Western world that come from the East, there are advocates and naysayers. It’s our aim to give you all the information you need in this guide to draw your own conclusion and answer the question: Do Vitamin C shower filters really work?
Let’s start with our Top 5 picks before moving onto our complete buyer’s guide and FAQ.
|Filter||Features & Highlights|
Now that you know the top Vitamin C shower filters currently on the market, let’ take a closer look at how we arrived at these filters and answer several frequently asked questions starting with the most important one.
Do Vitamin C shower filters work?
Before you make the leap to buy a Vitamin C shower filter, this is the first question you’ll most likely ask yourself. As with all new health products, it’s important to do a bit of homework before you buy.
Here’s what we found during our research. According to the City of San Francisco (sfwater.org), 1000mg of Vitamin C added to a medium-sized bathtub will completely remove chlorine and neutralize chloramine. Furthermore, Vitamin C is a common reducing agent used for dechlorination.
AWWA Standard (AWWA, 2005b) includes Vitamin C as an agent for dechlorination in disinfected water mains. The drawback that sfwater.org notes is that Vitamin C shower filter manufacturers overestimate the life of their filters (we have a fix for this to save you some bucks).
The last point to consider is there’s currently no NSF/ANSI Standard for dechlorination of water with Vitamin C. In other words, NSF/ANSI does not yet recognize Vitamin C as an effective filtration media for chlorine removal. For this reason, the lab test results provided by Sonaki are from a Korean lab.
Vitamin C Shower Filter Reviews
Since there are a lot of skeptics who don’t believe that Vitamin C shower filters work, we decided to do a deep dive into current Sonaki shower filter reviews and the other filters in our Top 5. We’re familiar with AquaBliss and trust them as a reputable shower filter manufacturer.
Here’s what we concluded after reviewing current Vitamin C shower filter reviews:
- The #1 complaint about the Sonaki filter is longevity. Current owners recommend performing consistent maintenance to avoid leaks and broken parts.
- Sonaki owners love the effect the Vitamin C shower water has on their skin and hair.
- Installation is easy for everyone.
- The Sonaki dual filter is recommended for people with blond hair who are experiencing a reddish tint or dry hair from chlorine exposure.
- Most users notice that the chlorine smell is completely gone.
- It appears that sfwater.org hit the nail on the head when they called out water filter companies for overestimating the life of the Vitamin C filters.
- People with chloramine-treated municipal water are noticing a positive effect on skin health since switching to a Vitamin C filter.
- There’s a reasonable belief that Vitamin C does not effectively remove chlorine at high flow rates and from hot water. This is important to note because sfwater.org added Vitamin C to a bathtub and allowed it to dissolve rather than testing water from a shower filter. We recommend using a DPD-1 chlorine test kit to test your tap water before and after.
A lot of current owners make their own Vitamin C replacement shower filters by adding Vitamin C powder to the orange Sonaki replacement filter housings.
Here’s what you need to make your own:
- Carefully pop off the top of the Sonaki replacement filter (you’ll find that the top is glued to the housing with varying strengths of glue depending on which batch you receive)
- Only apply pressure to the part of the filter above the black o-ring to release the cap (you may need to go around the top several times to gently break the glue away without cracking the housing)
- If the cap won’t budge, soak it in very hot water (not boiling) and try again
- Once you release the cap, flip the filter upside and tap out the seal and cap (save all the parts)
- Wash all parts with mild soap and a soft sponge, then allow them to air dry
- Pack the filter housing with Vitamin C powder until it reaches below the cap line
- Add a bit of water and pack down the Vitamin C powder again as much as possible below the cap line
- Replace the cap, o-ring, and cloth filter in their original positions, and you’re good to go! No need to worry about adding glue since the o-ring creates a seal
Vitamin C Shower Filter Benefits
The main benefit of a Vitamin C shower filter is chlorine & chloramine removal. Since chlorine wreaks havoc on hair, skin, and nail health – mostly due to its drying effect – Vitamin C helps to reverse this problem by removing chlorine.
Here are the benefits most users experience:
- More radiant and youthful-looking skin
- Softer, shinier hair
- Improved nail health
- Vitamin C has a slightly acidifying effect on water (unlike alkaline drinking water, acidic water has cosmetic uses including natural acne treatment)
- No more noxious chlorine odor while showering
- Eczema, dandruff, and psoriasis sufferers are finding relief with Vitamin C shower filters
- Get rid of dry itchy skin
Which brand is the best?
The best pure Vitamin C shower filter currently on the market is the Sonaki shower filter. While Vitamin C shower filter reviews are quite mixed across the board, current Sonaki owners who love theirs couldn’t live without it.
We recommend caring for the filter, following instructions carefully, and contacting Sonaki with any questions you have to get the best experience. Considering the Sonaki filter comes with a 1-year warranty and 120-day money-back guarantee, it’s worth a try.
We do believe Vitamin C shower filters work, and the key part is to buy from a trusted seller. Sonaki is the #1 manufacturer of Vitamin C shower filters in the world and the most trustworthy brand in our Top 5. It’s best to stick with them if you’re serious about buying the best Vitamin C shower filter for your home.
We recommend considering the dual-filter Sonaki system with additional activated carbon fiber for enhanced contaminant removal. We’re also big fans of the AquaBliss SF100 filter which includes a wide range of filtration media that’s proven to work.
KDF redox media is the chosen media to meet NSF/ANSI Standard 177 for chlorine reduction. Keep in mind, Sonaki and UBS Vita-Fresh shower filters do not meet NSF/ANSI Standards because there’s currently no NSF Standard for Vitamin C.
