The best welding helmet with respirator is the Optrel crystal 2.0 with e3000X PAPR: a crystal 2.0 helmet with Optrel's e3000X powered air (PAPR) blower and TH3 HEPA filter, which Optrel's US site says is NIOSH-certified.
There are two ways to protect your lungs while welding: a PAPR system that blows filtered air into the helmet, or a low-profile welding respirator worn under a normal helmet. The second costs a fraction and works for most hobby and shop welding; the first is for long shifts and hazardous fumes. See what a PAPR welding helmet is.

Pros
Optrel US states the e3000X is NIOSH-certified; TH3 HEPA filter
Three airflow levels: 170, 210 and 240 l/min
Up to 18 h battery; helmet has the crystal 2.0's shade 2.0 light state
Cons
$600+ — about four Viking 3350s
Optrel's page gives no NIOSH TC approval number — ask the seller
Helmet lens is 1/1/1/2 with a 50 × 100 mm window
Skip it if: Occasional welders — a low-profile P100 half mask under a standard helmet costs a fraction.
Spec score 53/100 (verified specs only, not a test score): Optical class 20/25 · Viewing area 15/25 · Arc sensors 11/15 · Switching speed 5/10 · Weight 0/10 · Warranty 0/5 · Value 2/10. How it works
Viking 3350 helmet: 1/1/1/1, 12.5 sq in, ANSI Z87.1-2010
HE particulate filter; 170+ / 210+ lpm airflow
APF 25 as a loose-fitting PAPR, per Lincoln's manual
Cons
Manual's approval table lists EN 12941 and AS/NZS 1716 — no NIOSH TC number found
Only one unit in stock and no buyer reviews when checked

PAPR (powered air): a belt blower pushes filtered air into a sealed helmet. No breathing resistance and a cool face. Our best PAPR welding helmet pick is below.
Half mask under a helmet: the Miller LPR-100 Half Mask, S/M is NIOSH-certified to P100 and Miller designed it to fit under most helmets. Tight-fitting masks need a fit test and a clean shave.
Best PAPR welding helmet
The best PAPR welding helmet we could buy on Amazon is the Optrel crystal 2.0 with e3000X PAPR: the only PAPR system that was new, in stock and sold by an established welding supplier when we checked, with a TH3 HEPA filter and three airflow levels. PAPR systems cost $600+, so make sure you need one; what is a PAPR welding helmet explains when it's worth it.
3M welding mask respirator systems
3M's Speedglas helmets with Adflo PAPR are common in industry, but the listings we found were sold by unknown third parties and labelled for industrial use only, so we don't rank them. 3M's half masks are a solid under-helmet option: the 3M 7502 Half Facepiece (M) with 3M 2097 P100 Filters (2 pairs) filters, which 3M lists for welding fume.
When do you need respiratory protection for welding?
OSHA requires exposure to stay below its limits; in practice, galvanised steel (zinc), stainless (chromium) and confined spaces almost always need a respirator. Our respirator for welding galvanized steel guide covers the hazards with OSHA and NIOSH sources.
Miller PAPR
Miller's PAPR II systems (with the T94 or T94i-R helmet) were listed on Amazon, but with no buyer reviews and a single unit from a reseller, so we don't rank them. If you want Miller's PAPR, buy it from a Miller distributor who can show the NIOSH approval label.
Miller welding respirator options
The Miller welding respirator most people should buy isn't a PAPR: the Miller LPR-100 Half Mask, S/M half mask is NIOSH-certified and fits under any helmet. Compare it on our welding respirator page.
Miller respirator vs PAPR
A Miller respirator (LPR-100) costs a small fraction of a PAPR and needs a fit test; a PAPR is loose-fitting, works with a beard and gives an assigned protection factor of 25 (Lincoln's manual cites OSHA's APF 25 for loose-fitting PAPRs).
Miller T94i and PAPR II with T94i-R
The Miller T94i is a premium helmet; the only T94-family listings on Amazon were the T94i XL (a different model with a larger window) and the PAPR II with T94i-R, both with too little availability and feedback to recommend. For a comparable helmet you can buy today, see the Miller Digital Infinity ClearLight 4x (Black) on our Miller welding helmets page.
Check the NIOSH approval before you buy
A US workplace PAPR must be NIOSH-approved as a complete system (blower, filter, helmet). Optrel's US page says the e3000X is NIOSH-certified but doesn't print the TC number; Lincoln's Viking PAPR manual lists EN 12941 and AS/NZS 1716 approvals. Ask the seller for the approval label in both cases.
