Frequently Asked Questions

The EvaClean Infection Prevention Program is a fully integrated program using a single chemistry solution throughout the whole cleaning process. By using one chemistry, NaDCC, throughout the cleaning process you eliminate confusion about what to use when. Our tablets have one set of directions for both cleaning (PurOne) and disinfecting (PurTabs).  By combining both the technology and chemistries into one complete solutions package, EvaClean allows workers and infection prevention experts to standardize their processes and eliminate many of the training and education challenges faced in programs that still use mops, buckets, wipes, rags, and spray bottles with a multitude of chemistries each with their own unique usage guidelines, dwell times, and safety procedures. The EvaClean Program optimizes workflow, simplifies training, and reduces costs, while delivering more predictable and repeatable results that greatly exceed those of current disinfection and sanitizing programs.

Once charged the battery will run continuously for 4 + hours.

The battery can be recharged up to 2,000 times, which will give you an estimated 3-4 years of use.

The function of the LED light is to provide better viewing clarity in dark spaces.

All of our sprayers have ETL Certification which is the equivalent to UL and certifies that the products have met all the minimum safety standard requirements established by OSHA and carried out by Nationally Recognized Testing Laboratories. The selection of either certification largely comes down to the ETL having a larger pool of testing facilities and the ability to process registrations faster than UL. Neither carries any benefit over the other.

The settings on the tri-nozzle were designed for different functions and dwell times. The smaller setting is for sanitizing, the middle setting is for disinfecting, and the larger setting is for heavier saturation, i.e. fabrics or soft surfaces. Please reference the “Operation Instructions” for detailed descriptions.

A 32oz tank will cover about 800-1,000 square feet. The variation is dependent on nozzle setting and surface material.

The electrostatic charge of the sprayer allows the droplets to attract to the surface rather than float in the air, as is typically associated with a mister or fogger. Misters and foggers are associated with worker exposure and respirable concerns. EarthSafe has conducted OSHA and NIOSH third party testing ensuring that there are no safety concerns for acute or long term worker exposure. It was established that exposure levels or PurTabs when sprayed with the Protexus Electrostatic Sprayer fall below established Permissible Exposure Levels (PEL).

No. It is a mechanical sprayer and is simply an alternative method of application from traditional spray bottles. The electrostatic charge (which can be turned on or off by the user) is simply an assistive mechanism to aid the user in more efficient and comprehensive application of EPA Registered chemical disinfectants and sanitizers to surfaces.

No. Again, the sprayer is a mechanical sprayer and is simply an alternative method of application from traditional spray bottles.

You will call our customer support number to troubleshoot the issue, and determine whether it needs repair or falls under warranty.

With proper care, the sprayer should last like any other piece of battery powered equipment. The sprayer should be regularly flushed, and should never be stored with any solution. Please see “operations instructions” for proper care.

There is a 1-year limited warranty from the date of purchase on defects due to materials or workmanship. We do not accept returns or exchanges unless the item purchased has defects due to materials or workmanship. If you believe you received a defective item, under warranty, please complete the warranty form at

At a 4306 ppm concentration (4 minute C.diff claim), it may leave some residue, which would need to wiped with water once dry. With all other concentrations, residue will not be left on plastic or stainless steel. Over-saturation or hard water deposits may also cause streaking.

With a two-step process, cleaning and disinfecting, using a spray application can reduce time by up to 40%.

Yes. You will still remove gross soil (unlike a one-step process where you would have to clean/disinfect every spot by keeping it wet for the required amount of time), and then spray to achieve complete and quick sanitizing or disinfection. PurOne can be used with micro-fiber cloths, dry wipes, and spray bottles to clean/disinfect surfaces prior to disinfecting.

Both PurOne and PurTabs Chemistry is based around NaDCC, an organic chlorine donor which releases Hypochlorous Acid (HOCl) and Monosodiumcyanurate (NaOCl) when dissolved in water. PurOne, unlike PurTabs, has a surfactant to help kill bacteria in biofilm. PurTabs are formulated for final disinfection with touchless spray application. PurOne is the front end of the EvaClean Program used for cleaning and disinfecting, while PurTabs is a broad-spectrum disinfectant.

Yes. PurOne and PurTabs have slight chlorine smell that dissipates quickly after application leaving what most end users describe as a “clean” or “sterile” smell.

The CDC states that household bleach while having a broad spectrum of antimicrobial activity, contributes to ocular irritation or oropharyngeal, esophageal, and gastric burns, is corrosive to metals in high concentrations (>500 ppm), is inactivated by organic matter, discolors or "bleaches" fabrics, and releases of toxic chlorine gas when mixed with ammonia or acid (e.g., household cleaning agents). The CDC further states that alternative compounds that release chlorine, such as sodium dichloroisocyanurate (NaDCC – PurTabs/PurOne), are more advantageous in that they retain chlorine longer and so exert a more prolonged bactericidal effect. Sodium dichloroisocyanurate tablets are stable, the microbicidal activity of solutions prepared from sodium dichloroisocyanurate tablets are greater than that of sodium hypochlorite solutions containing the same total available chlorine. (CDC Guidelines for Disinfection and Sterilization in Healthcare Facilities For schools or daycare, the CDC further recommends the use of a EPA registered disinfectants.

No. EarthSafe conducted independent third party testing with American Environmental Consultants, Inc. to conduct personal air sampling. These were performed by a trained industrial hygienist using OSHA and NIOSH sampling techniques. All results verified that spraying PurTabs with the Protexus Sprayer fall below published accepted Permissible Exposure Limits (PEL) and Threshold Limit Value (TLV).

EvaClean can be used around standard office equipment such as laptops, desktops, keyboards and monitors but should not be applied directly to any sensitive electronics. Before applying, reference the equipment manufacturer's instructions for cleaning and disinfecting.

Unlike bleach, PurTabs and PurOne do not discolor fabrics. They should not be used on non-colorfast fabrics, wool or silk fabrics, or any fabric with a special finish. If applying around fabrics, test on an inconspicuous area prior to use.
