A note on claims

EcoloxTech generators are regulated by the EPA as devices, are not registered disinfectants, and we make no efficacy claims for them or for the solution they produce. The only EcoloxTech product with disinfection claims is HOCl-AS200 (EPA Reg. No. 101112-1), used according to its label. What applies where is set out on our regulations page and in staying compliant with HOCl. Research referred to describes published studies under their own test conditions and is not a claim for any product.

Bleach has been the go-to disinfectant for decades. But times are changing.

Today’s consumers and industries want safer, faster, and more sustainable solutions—and hypochlorous acid (HOCl) is leading the charge.

If you’re still using bleach, this blog will change the way you see sanitation.

The Problem With Bleach

Bleach (sodium hypochlorite) is a strong disinfectant, but it comes with serious downsides:

  • Requires PPE to handle

  • Efficacy claims belong to registered products used according to their labels: EcoloxTech generators are EPA-regulated devices and carry none, and the only EcoloxTech product with disinfection claims is HOCl-AS200, EPA Reg. No. 101112-1.

  • Leaves harmful residues

  • Causes corrosion and damage to surfaces

  • Produces toxic fumes and byproducts

  • Must be rinsed off after use

  • Degrades and loses potency over time

Why HOCl Works Better

HOCl is the same molecule your white blood cells produce to fight infection.
It’s highly effective at penetrating pathogen cell walls—yet remains to humans.

HOCl is also up to 100 times more effective

The Hidden Costs of Bleach

When you use bleach, you’re paying for more than just the bottle:

  • PPE and employee training

  • Post-use rinsing and water waste

  • Extra labor time

  • Chemical storage and inventory

  • Damage to surfaces and equipment

  • Environmental compliance fees

In high-stakes settings like healthcare and food production, even small bleach-related mistakes can carry major risk.

Why Leading Brands Are Switching to HOCl

Companies like Norwegian Cruise Line switched after dealing with costly damage and sanitation challenges caused by bleach.

Now, they generate HOCl on-site with EcoloxTech systems, reducing outbreaks and chemical waste.

Other adopters include restaurants, dental offices, seafood processors, and cannabis labs—choosing HOCl to:

  • Protect staff and customers

  • Lower operational costs

  • Increase safety and compliance

How to Switch from Bleach to HOCl

With EcoloxTech’s on-site generators, you can make fresh, effective HOCl in-house—for just pennies per gallon:

  • No hazardous shipping

  • No corrosive storage

  • No supply delays

Choose from:

  • Eco One – for homes and small clinics

  • E-300 – ideal for schools, restaurants, labs

  • E-1200 – for factories, processing plants, large facilities
