PurOne
PurOne is EPA-registered as a healthcare disinfectant for hard, non-porous surfaces in critical areas potentially contaminated with Candida auris, under EPA Registration 71847-7.
4306 ppm · 2 minutes
2153 ppm · 6 minutes
Both are registered. Choose based on what your protocol can realistically hold on the surface, not on which number looks better.
Putting it into a protocol
-
Pre-clean.
Fecal matter and waste are thoroughly removed before disinfection. Vigorous wiping or scrubbing until all visible soil is gone.
-
Prepare the solution.
4306 ppm available chlorine. Tablet counts and water volumes are on the dilution chart.
-
Apply and hold.
Surfaces stay visibly wet for the full two minutes. If the surface dries early, the claim does not apply.
-
Direction of work.
Right to left or left to right on horizontal surfaces, top to bottom on vertical. Restrooms last. Do not reuse soiled cloths.
-
Coverage.
Manual wiping misses three-dimensional surfaces. Electrostatic application reaches IV poles, wheelchair frames and bed rails.
Published, peer-reviewed, head to head
A study published in the American Journal of Infection Control in June 2022 ran for eighteen months across two hospitals and analyzed 774 surface samples. It compared sodium dichloroisocyanurate (NaDCC / sodium troclosene), the chemistry behind PurOne, head to head against a peracetic acid and hydrogen peroxide system and an electrolyzed water system.
Sodium dichloroisocyanurate produced significantly lower colony counts than either comparator, and the authors concluded it was the best sporicidal disinfectant in the study. Adding electrostatic application reduced counts further still.
Available in two tablet sizes

PurOne 3.3g, 200-count tub

PurOne 13.1g, loose pack
Both dissolve in water to the concentration your protocol requires. Concentrated tablets remove the cost and weight of shipping water, and the dilution chart converts tablet count to available chlorine.

Frequently asked
Is PurOne effective against Candida auris?
Yes. PurOne is EPA-registered against Candida auris on hard, non-porous surfaces at 4306 ppm available chlorine with a two minute contact time, and at 2153 ppm with a six minute contact time, under EPA Registration 71847-7.
What contact time does Candida auris require?
Two minutes at 4306 ppm, or six minutes at 2153 ppm. The surface must remain visibly wet for the full duration. If it dries early, the claim does not apply.
Why are there two concentrations?
Both are registered. A higher concentration with a shorter contact time suits terminal cleans where the room is empty. A lower concentration with a longer contact time may suit routine work. Choose based on what your team can hold in practice.
Can I use PurOne with an electrostatic sprayer?
Yes. Electrostatic application provides wraparound coverage on three-dimensional surfaces that manual wiping misses.
How do I know my team is achieving the contact time?
Audit it. Time how long a treated surface stays visibly wet in a real room, not a test bench, and check wipe saturation at the end of a room rather than the start.
