CleanSpace WORK Powered Half-Mask Respirator Overview

What This Respirator Is Built For

A respirator only protects within a complete, matched, compliant system. Unlike a loose-fitting head top, the WORK is a tight-fitting half mask, so it requires fit testing for each wearer and a clean-shaven seal, and a user seal check before every use; facial hair breaks the seal and voids the protection. It uses a particulate P3 filter, so it captures dusts and fumes but does nothing for gases or vapors, which need a respirator and media rated for the hazard. Because a PAPR purifies ambient air rather than supplying it, it is not for IDLH or oxygen-deficient atmospheres, which require an SCBA or a supplied-air respirator rated for those conditions. Confirm the size by fit test, replace the filter when it is loaded, damaged, or wet, keep the unit charged, and run the system within a written program under OSHA 29 CFR 1910.134.

Frequently Asked Questions

What is the CleanSpace WORK powered half-mask respirator?

It is a no-hose powered air-purifying respirator with the blower and battery mounted on a tight-fitting half mask, so there is no belt, hose, or waist battery. At about 340 grams it is one of the lightest PAPRs, and the blower responds to your breathing.

What filter does the WORK kit use?

It uses a TM3 P3 (HEPA-class) particulate filter that captures about 99.97% of dust and fine particles. It is a particulate filter, so it handles dusts, mists, and fumes but does not protect against gases or vapors.

What assigned protection factor does it provide?

As a tight-fitting half mask it carries an OSHA assigned protection factor of 50, higher than a loose-fitting head top. Achieving that protection depends on a correct fit, so fit testing and a good seal are essential.

Does it require fit testing?

Yes. Because it is a tight-fitting half mask, it requires fit testing for each wearer under OSHA and the equivalent standards, plus a user seal check before each use. It also requires a clean-shaven seal area, since facial hair breaks the seal.

Why is there no hose or belt?

CleanSpace mounts the blower and battery on the mask itself, which removes the hose, belt, and waist battery of a traditional PAPR. That makes it lighter and less likely to snag, and it frees your waist and back for other tasks.

How does the breathing response work?

The blower senses your breathing and adjusts airflow to match, delivering air as you inhale. This helps runtime and comfort. Always perform the seal check and confirm the unit is responding before you rely on it for protection.

What size should I choose?

This kit is the small mask. CleanSpace offers other sizes, so select the size that passes a fit test for the wearer. A mask that does not fit will not seal, so confirm the size through fit testing rather than guessing.

Does it protect against gases or vapors?

No. The WORK kit uses a particulate filter only. It does not protect against solvent vapors or acid gases. If your work involves those exposures, you need a respirator and filter or cartridge rated for them, matched to the hazard.

Can I use it in an oxygen-poor or emergency atmosphere?

No. Because a PAPR filters ambient air rather than supplying it, it is not for oxygen-poor or immediately dangerous atmospheres. Those require respiratory protection rated for such conditions, and you must confirm the environment first.

What temperature range does it work in?

CleanSpace lists a use range of about 14°F to 113°F at under 90% relative humidity. Store and charge it within the manufacturer's limits, and keep the filter dry, since a wet filter must be replaced.

Do I need a written respiratory program?

Yes. Powered air-purifying respirators are used within a written respiratory protection program under OSHA 29 CFR 1910.134, including training, medical evaluation, fit testing, and maintenance. Follow the CleanSpace manual for use and care.

How do I maintain it?

Inspect the mask, valves, seal, filter, and battery before each use, run a seal check, replace the filter when breathing is harder or it is damaged or wet, and keep the unit clean and charged. Follow the CleanSpace manual for intervals and parts.
