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.

For technical information on EvaClean please see: https://www.evaclean.com/resources

Only PURTABS and other EarthSafe approved products (including those that are a part of the EvaClean Program) have been tested, verified, and measured to achieve repeatable results, based on application and dwell times. EarthSafe makes no warranties or representations regarding products that are not part of the EvaClean Program. For non-infection control chemical applications, EarthSafe has other electrostatic spraying solutions.

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 5 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.

Each setting was specifically 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.

We have technicians that can fix or replace the unit (if warranty claim) within 5 business days.

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.

PURTABS are stable for 7 days once diluted and stored in a closed container. In an open container, the solution is stable for 24 hours.

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. Disinfecting and sanitizing with the electrostatic sprayer is not a substitute for proper cleaning protocols.

Yes, there are labels available for purchase for each concentration that will affix onto the sprayer tank.

Yes. It will be safe to spray for sanitizing at the small nozzle setting as long as proper application methods are followed. Electronic devices and equipment should not be saturated.

In most environmental conditions the electrostatic wrap allows workers to achieve 3 x the coverage of a traditional spray bottle. However, in certain environmental conditions (i.e. wind, room humidity, etc.) delivery with the sprayer may not be completely uniform. Wrap should encompass 3-4 inches around each sprayed object. In certain instances, one will have to spray around certain objects and surfaces to obtain full coverage due to size, distance and substrate variations.

With a two-step process, cleaning and disinfecting, the use of sprayer can reduce time by up to 40%.

Yes. You will still remove visible 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.

The PURTABS Chemistry is based around NaDCC, an organic chlorine donor which yields Hypochlorous Acid (HOCl) and Monosodiumcyanurate (NaOCl) when dissolved in water. This solution results in a free available chlorine count (ppm) that is easily measurable with test strips to ensure the solution concentration is consistent with usage guidelines and all of the efficacy claims and data that are on our EPA Registered Label. There are 3 tablet size options to make mixing the proper concentration simple.

Yes. PURTABS has 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), 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 https://www.cdc.gov/hicpac/disinfection_sterilization/6_0disinfection.html).

For schools or daycare, the CDC further recommends the use of a EPA registered disinfectants. https://www.cdc.gov/flu/school/cleaning.htm.

It is an EPA registered hospital grade disinfectant which is an obvious requirement for any chemical disinfectant or sanitizer and strictly measures the efficacy of the chemical itself. PURTABS sprayed with the Protexus Electrostatic Sprayer was independently tested and verified that exposure levels fall below established Permissible Exposure Levels (PEL) in compliance with OSHA and NIOSH.

No. EvaClean / 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 Electrostatic Sprayer fall below published accepted Permissible Exposure Limits (PEL) and Threshold Limit Value (TLV).
