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.
1076 ppm or 4306 ppm available chlorine, matched to whether the room is wiped or sprayed. Tablet counts and water volumes are on the dilution chart.
-
Apply and hold.
Surfaces stay visibly wet for the full contact time listed above. 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 other complex geometry.
Frequently asked
Is PurOne effective against MRSA?
Yes. PurOne and PurTabs are both EPA-registered against MRSA and GRSA, by electrostatic sprayer and by general surface application.
What contact time does MRSA require?
4 minutes at 4306 ppm (electrostatic sprayer or general application), or 2 minutes at 4306 ppm for general application.
Do PurOne and PurTabs perform differently against MRSA?
No — per the approved claims sheet, the claims are identical across both products for this organism, at every ppm/contact-time pairing and both application methods.
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.
