Acid water has a wide range of uses, from the beauty industry to horticulture to cleaning. Find out the benefits of this incredibly diverse product here:


Before diving into the benefits and uses of acid water, we first need to understand exactly what acid water is. The pH of a substance determines whether it is acidic, alkaline, or neutral. The pH scale ranges from 0 to 14. The pH table is organized as follows (1):

From this, we can see that acid water is water that has a pH less than 7.

different foods and chemicals being compared on the pH scale


Where your water comes from determines how acidic or base it is. Bottled water tends to be slightly more on the acidic side, while water from wells tends to be more alkaline. The United States Environmental Protection Agency (EPA) recommends the pH of drinking water be between 6.5 and 8.5 on the pH scale (2). It is not recommended to drink acid water nor alkaline water that falls outside of this range.


If you are looking for a product that protects the inherent genetic makeup of your skin while still combating acne, wrinkles, and other unwanted conditions, then look no further than acid water (3). Acid water takes into account the delicate pH balance of your natural skin and helps with skin conditions, hair health, and even dental hygiene.


Your skin has a thin film known as the acid mantle. This very thin layer sits on the surface of your skin and functions as a protective barrier against viruses, bacteria, and other contaminants.

Did you know that the natural pH of your skin is between 4.5 and 6.2 on the pH scale (4)? Using water that has around the same acidity as your skin can help keep your natural pH level balanced. However, this also means that when you use alkaline products, your skin’s acid mantle is stripped away, leading to an upset in your natural pH levels. This upset may cause dry, oily, or inflamed skin, and can lead to skin conditions like eczema and acne (5)(6).

Using acid water in your skin care routine can help smooth skin, improve overall skin glow, and improve skin condition. By protecting your skin’s natural acid mantle, acidic water can help minimize acne, skin discoloration, rashes, and bumps. As a natural astringent, acid water is able to help minimize pores and remove dirt and oil from your skin without the use of chemicals.


Yes! Acid water is capable of treating a number of skin conditions. These include (7):

  • Sunburns: Instead of using alkaline products to relieve your sunburn, use acid water to reduce pain and redness and to help your skin heal faster.
  • Insect bites: Acid water has also been known to help relieve the itch and sting of many insect bites.
  • Burns: Acid water can help to soothe the pain from a burn and may help decrease recovery time.
  • Chapped hands: Use acid water to help speed your recovery from chapped hands by reinforcing your skin’s acid mantle.
  • Athlete’s foot and nail fungus: Acid water can be used to treat foot and nail fungus. Simply soak your foot in warm acidic water for 20 to 30 minutes a day to help with recovery.
  • Eczema: Help keep your skin clean and minimize itching by using acid water.
  • Minor scratches and cuts: As a disinfectant, acid water helps to clean wounds and accelerate recovery from minor abrasions.


Acid water is able to minimize hair loss, decrease dandruff, relieve itchy scalp, and improve the overall condition of your hair. According to one study published by the International Journal of Trichology (8), using a shampoo with an alkaline pH will cause frizz, increased hair friction, hair cuticle damage, and fiber breakage.


Because of its anti-inflammatory properties acid water is able to function as an effective aftershave. Acid water is able to prevent painful and itchy razor burn. It does this by reducing swelling, redness, and lesions.

Americans spend millions of dollars on household cleaning products every year. That is a lot of chemicals that you are being exposed to. Acid water is an effective way to clean without chemicals (11). Hypochlorous acid is a non-toxic cleaning substance that is 80 to 200 times more effective than bleach in surface disinfection (12). Hypochlorous acid (HOCL) and sodium hypochlorite (NaClO) are effective cleaning waters.

Uses of Hypochlorous Acid (HOCl):

  1. Treats acne, eczema, and other skin issues
  2. Powerful disinfectant for surfaces
  3. Wound care (13)
  4. Eye care (14) (HOCI can only be used for eye care in very small, diluted doses. Do not use HOCI on your eyes before consulting your primary healthcare professional.)
  5. Used in organic crop production (15)
  6. Produces preservatives (16)
  7. Used for diabetic skin ulcers (17)
  8. Food disinfectant (17)

Uses of Sodium Hypochlorite (NaClO):

  1. Bleaching agent (18)
  2. Strong disinfectant (18)
  3. Used in healthcare facilities for cleaning and disinfecting (19)
  4. Antiseptic, used to clean topical wounds (18)
  5. Anti-infective (18)
  6. Can remove mold stains and dental stains (20)

Depending on what you are cleaning, a different pH level is needed (21)(22)(23):

Acid water has great antiseptic and antibacterial qualities. Because acid water has disinfection qualities, it is an effective way to:

  • Clean your hands
  • Sterilize minor wounds
  • Wash fruit
  • Be used as a natural mouthwash to combat bad breath and plaque


The Echo Ultimate™ can make four different types of water, right from the comfort of your home. The Echo Ultimate™ gives you access to filtered water, hydrogen water, alkaline water, and acid water at the click of a button.

You can choose between four different pH levels depending on what you intend to use the acid water for:

  • Level 1: Weak acidic water. This is used for washing your face and for oral hygiene, eg. as a mouthwash.
  • Level 2: Weak to medium acid water. This is used for washing your hair and body, as an astringent, and for skin conditions.
  • Level 3: Medium to strong acidic water. This is used for disinfection purposes like cleaning your kitchen.
  • Level 4: Strong acidic water. This level is used for heavy disinfection like sterilizing an area where raw meat or fish has been, and for washing produce.
