The KleenGuard A40 coverall is a white disposable protective suit built on Microporous film laminate. The A40 is the crossover suit: a microporous film laminate that stops light liquid splash while staying more breathable than coated chemical garments. It covers the wet-and-dirty middle ground — pressure washing, industrial cleaning, wet trades — where a dust suit wets through and a chemical suit is overkill. Our listing starts at $133.33, with the size run on the linked Amazon page.
Why the KleenGuard A40 Stands Out
The A40 is the crossover suit: a microporous film laminate that stops light liquid splash while staying more breathable than coated chemical garments. It covers the wet-and-dirty middle ground — pressure washing, industrial cleaning, wet trades — where a dust suit wets through and a chemical suit is overkill.
Fabric, Configuration and Protection
Liquid splash and particulate barrier — light liquid spray plus dry particulates in one garment. Configuration: zip front, elastic wrists and ankles. It is the mid-rung of the KleenGuard ladder: above the A20, below the A60/A70. Like every disposable garment, it is a single-exposure product — once contaminated, it comes off at the work boundary and enters the waste stream your standard requires.
Fit follows the disposable-coverall rule: order one size over street clothes so the suit survives crouching and reaching. Elastic interfaces seal approximately, not absolutely — for regulated work, tape the glove and boot junctions and treat the suit as one layer of a system that includes hazard-matched gloves, eye protection, and the respirator your assessment names.
Where It Falls Short
Its limits: Named chemical exposure — the A40 handles water-based splash, not chemical spray; that is the A70's job, and biologicals are the A60's. No disposable coverall is a submersion garment, an arc-flash layer, or a substitute for the engineering controls that come first in the hierarchy.
Pros and Cons
Pros
- Microporous film laminate matched to a clearly defined hazard
- Zip front, elastic wrists and ankles
- Listed from $133.33 with live Amazon pricing
- Single-use discipline — no decontamination ambiguity
Cons
- Disposable garment — not for exposure beyond its rating or duration
- Not rated for named chemicals or biologicals
Who Should Buy It
Order the KleenGuard A40 if you are industrial cleaners, pressure washers, and wet-trade crews who need liquid-plus-particle coverage without full chemical rating.
Who Should Skip It
Skip it for named chemical exposure — the A40 handles water-based splash, not chemical spray; that is the A70's job, and biologicals are the A60's.
How It Compares
The A60 shares the laminate construction and adds ASTM F1670/F1671 bloodborne certification — if blood or body fluids are on the hazard list, only the A60 qualifies. Both sit inside the field ranked in our best disposable coveralls guide, and the disposable coveralls collection carries the full ladder from breathable particle suits to taped-seam chemical barriers.

Frequently Asked Questions
What is the KleenGuard A40 coverall rated for?
Liquid splash and particulate barrier — light liquid spray plus dry particulates in one garment. The rating, not the price, picks the suit — match it to your hazard assessment.
What fabric is the KleenGuard A40 made of?
Microporous film laminate (KleenGuard A40). That fabric choice is the core of what it protects against and how it wears.
What sizes does the KleenGuard A40 come in?
Our listing carries one stocked configuration; the linked Amazon page lists the available sizes. Order one size over street clothes — undersized coveralls tear at the crotch and shoulders.
Is the KleenGuard A40 reusable?
No. It is a single-use garment: once worn against the hazard it was chosen for, it is doffed at the work boundary and disposed of per the governing standard.
KleenGuard A40 vs KleenGuard A60 — which should I buy?
The A60 shares the laminate construction and adds ASTM F1670/F1671 bloodborne certification — if blood or body fluids are on the hazard list, only the A60 qualifies.
Does the KleenGuard A40 have a hood?
No — it is a zip front, elastic wrists and ankles. Choose a hooded suit when the contaminant is airborne or overhead.
What respirator should I pair with the KleenGuard A40?
The hazard that picked the suit picks the respirator: P100 filters for dusts, fibers, and mold; chemical cartridges for vapors and spray. Start with our when-do-you-need-a-respirator guide and the respiratory protection collection.
Are the seams on the KleenGuard A40 sealed?
Zip front, elastic wrists and ankles. Serged seams suit particulate duty; taped seams close the stitch-hole leak path chemical work demands — that distinction is exactly where the Tychem 4000 and 6000 earn their premium.
How much does the KleenGuard A40 cost?
From $133.33 on the linked Amazon listing; check the listing for the pack count at your size. Prices track the live listing.
Is the KleenGuard A40 waterproof?
Its laminate resists liquid splash within its rating, but it is not a rain or immersion garment.
Can I wear the KleenGuard A40 for asbestos or mold remediation?
For regulated abatement, crews spec a hood-and-boots Tyvek 400 TY122S so there is no gap at the footwear; this suit serves other duties better.
What color is the KleenGuard A40, and does color matter?
White. Color is convention, not protection — white for particulate suits, yellow for chemical garments, blue for biological and site-visibility roles.
Can I wear the KleenGuard A40 over regular work clothes?
Yes — that is the intended use. Coveralls layer over clothing; size up so the seams are not loaded when you crouch.
What do I do with the KleenGuard A40 after use?
Doff at the boundary of the work area, folding the contaminated surface inward, and dispose per the standard that governs your hazard — regulated waste for asbestos, lead, or biological work; general industrial waste otherwise.

The Bottom Line
The KleenGuard A40 earns its slot in the lineup: liquid splash and particulate barrier in a disposable garment at a defensible price. It is the mid-rung of the KleenGuard ladder: above the A20, below the A60/A70. Rated 4.2/5 on grade, configuration, and value for the intended hazard.
