Tyvek is the name everyone says when they mean "disposable coverall," and DuPont's Tyvek 400 line earns it: flashspun high-density polyethylene in a single material that handles dry particulates and light splash across abatement, insulation, painting, and dirty-work duty. Kimberly-Clark's KleenGuard answers with a graded A-series — A20 breathable particle protection, A40 liquid and particle barrier, A60 bloodborne and splash, A70 chemical spray — so instead of one fabric for everything, you pick the barrier level the task actually needs.

That structural difference is the real comparison: one famously versatile material versus a laddered lineup. We stock both — three Tyvek 400 configurations and the four KleenGuard grades — and this guide matches them to the work.

Quick Decision — DuPont Tyvek 400 vs. KleenGuard A-Series
  • Tyvek 400 when: the job is dry particulates and light splash — abatement, insulation, grinding dust, paint overspray — and you want the proven default at low per-suit cost
  • KleenGuard when: you're laddering protection by task — breathable A20 for hot dusty work, A40 for liquid exposure, A60 for bloodborne duty, A70 for chemical spray
  • Either brand: the configuration (hood, boots, elastic cuffs) and the taping/sealing discipline decide real-world protection as much as the fabric

Tyvek 400: The Versatile Default

Tyvek's flashspun polyethylene is a genuine oddity: one continuous material — not a laminate, not a coated fabric — that blocks fine particulates down to hazardous-dust duty while shedding light liquid splash, yet stays tear-resistant enough to survive real work. That's why the same suit shows up in asbestos and mold abatement, fiberglass insulation, concrete grinding, and spray-paint bays. The stocked configurations map to those jobs: the TY122S with hood and attached boots is the abatement standard (full envelope, tape-ready), the TY127S hooded suit covers Type 5/6 particle-and-splash duty, and the collared TY125S with elastic cuffs handles general dirty work where a hood is overkill.

Know the line's ceiling: Tyvek 400 is not chemical protective clothing — pressurized spray, aggressive liquids, and hazmat duty belong to DuPont's Tychem tier, a distinction our Tyvek vs Tychem reference covers in depth. Within its lane, per-suit economics are the quiet win — at $9–$14 a suit, single-use discipline (the entire hygiene point of disposables) actually gets followed.

KleenGuard A-Series: Pick the Barrier, Not the Brand

KleenGuard's ladder means you stop paying for barrier you don't need and stop under-protecting when you do. The A20 emphasizes breathable particle protection — the hot-attic and summer-demo answer, where heat stress is the competing hazard and a heavier suit gets unzipped (defeating everything). The A40 steps to a genuine liquid and particle barrier for washdown-adjacent and splashy industrial work. The A60 adds bloodborne pathogen and chemical splash duty for remediation and biohazard-adjacent roles, and the hooded A70 tops the stocked range for chemical spray protection.

Case economics change the purchasing math — the stocked KleenGuard listings run $133–$225 as multi-suit cases, which is how facilities that burn suits daily should buy anyway. Sizing discipline matters as much as grade: a suit that binds at the shoulders tears at the task, and one that bags at the ankle finds the ladder rung. Order a size split per crew, not a single median size, and remember every grade's real seal lives at the cuffs, zipper flap, and hood edge — tape where the task justifies it.

Use-Case Decision Guide

Asbestos, Mold, and Lead Abatement — Tyvek TY122S

The hood-and-boots envelope with taped wrists and mask interface is the containment-industry standard for a reason: one garment, one doffing sequence, predictable disposal. Follow the site's regulated-work plan for donning/doffing order — the suit is only as good as the exit protocol.

Hot-Weather Dust Work — KleenGuard A20

Insulation in July, attic demo, grain dust: the breathable A20 keeps the suit zipped because the wearer can stand it. An unzipped higher-grade suit protects less than a zipped A20 — heat compliance is protection.

Industrial Liquid Splash and Washdown Support — KleenGuard A40

Where the exposure is liquids splashing rather than dust floating — food-plant sanitation support, equipment washdown, coolant-heavy machining — the A40's liquid barrier is the working grade. Pair with the splash-rated eyewear from our goggle vent guide.

Trauma-Scene, Remediation, and Bloodborne Duty — KleenGuard A60

OSHA 1910.1030 exposure-control work needs garments rated for it — the A60's bloodborne pathogen and splash protection covers cleanup and remediation roles that Tyvek 400 was never scoped for. Glove and eyewear selection carry equal weight in the ensemble.

Chemical Spray Applications — KleenGuard A70, Then Reassess Upward

The hooded A70 handles chemical spray duty at the top of the stocked range. If the SDS talks pressurized exposure, immersion, or toxic-by-skin-contact chemistry, you've left disposable-coverall territory entirely — that's the Tychem conversation in the reference guide.

Frequently Asked Questions — DuPont Tyvek 400 vs. KleenGuard A-Series

Is Tyvek or KleenGuard "better"?

Wrong axis — Tyvek 400 is one very good particle-and-light-splash material; KleenGuard is a graded range from breathable-particle to chemical spray. The buying question is which protection level the task needs; both brands are first-tier within their stated duties.

What do KleenGuard's A-numbers mean?

Ascending barrier tiers as stocked: A20 breathable particle protection, A40 liquid and particle barrier, A60 bloodborne pathogen and chemical splash, A70 chemical spray protection. Higher numbers trade breathability and cost for barrier.

What is Tyvek actually made of?

Flashspun high-density polyethylene — a continuous nonwoven of ultrafine HDPE fibers. The structure blocks fine particulates and light splash while breathing modestly and resisting tears, which is the combination that made it the disposable-coverall default.

Which suits work for asbestos or mold abatement?

The hooded, full-envelope configurations — the Tyvek TY122S (hood and boots) is the canonical abatement suit; hooded KleenGuard grades serve the same envelope logic per site spec. The containment plan's taping and doffing requirements govern the details.

Are these suits chemical protective clothing?

No — chemical spray duty tops out at the A70 within these lines, and genuine chemical protective clothing (pressurized exposure, aggressive chemistry, hazmat) is a different category: DuPont's Tychem line and equivalents. The boundary is drawn precisely in our Tyvek vs Tychem reference.

Can disposable coveralls be reused?

They're designed single-use, and contaminated suits (abatement, bloodborne, chemical) must be disposed as the contamination dictates — reuse defeats the hygiene model entirely. For clean-dirt tasks (dust-free painting, brief visits), a visibly intact suit re-worn by the same person the same day is common practice; treat anything beyond that as false economy.

How should coveralls fit?

One size up from street clothes is the working rule — you need range of motion at the knees and shoulders without webbing tight (tears) or bagging loose (snags). Elastic-cuff configurations seal to gloves and boots better; attached boots and hoods extend the envelope where the task demands.

Do I tape the cuffs and zipper?

Where the hazard justifies a sealed envelope — abatement and remediation, yes, per the site plan (wrists to gloves, ankles to boots, zipper flap, hood to respirator). For general dusty work, elastic cuffs alone are standard. Tape choice and sequence come from the containment protocol, not improvisation.

What respirator pairs with these suits?

Whatever the airborne hazard assessment says — the suit and respirator solve different exposures. Abatement work typically pairs hooded suits with half- or full-face respirators; the selection logic starts at N95 vs KN95 vs P100.

Why are the KleenGuard listings so much more expensive?

Case quantities — the stocked KleenGuard prices are multi-suit cases while the Tyvek listings are single suits. Normalize per suit before comparing; at volume, both brands land in the same order of magnitude within comparable grades.

Do these suits protect against heat or fire?

No — standard disposable coveralls are not flame-resistant, and some melt. Hot-work and arc-exposure environments need FR-rated garments (DuPont and others make FR disposable lines); never wear standard polyethylene-based suits over ignition-source work.

Which should a general contractor stock as the default?

A case of TY125S for general dirty work, TY122S for anything containment-flavored, and a case of A20 for the hot months — that trio covers most jobsite reality under $300. Add the A40/A60/A70 grades when specific liquid, bloodborne, or spray tasks appear on the schedule.

Compliance Note

Coverall selection is a hazard-assessment outcome under OSHA 1910.132 — match the garment's stated protection (particle, liquid splash, bloodborne, chemical spray) to the exposure, and mind the sister rule: a suit protects nothing at the wrists, ankles, and zipper it doesn't seal.
