Gerson GX70 P100 Respirator Cartridges — 2-Pack
The Gerson GX70 is a NIOSH P100 respirator cartridge for use with Gerson half-face respirators and Gerson full-face respirators, sold as a 2-pack (1 pair). P100 certifies 99.97% minimum filtration efficiency against all solid and liquid particulate aerosols, including oil-based mists — the highest efficiency level NIOSH assigns to air-purifying respirator cartridges and filters, and fully oil-proof with no time restriction. The GX70 is designed for professionals in construction, industrial, and manufacturing environments where high-efficiency particulate protection is required: silica dust from concrete and masonry, metal fume from welding and cutting, lead dust from abatement and renovation, and oil mist from machining operations. Each 2-pack equips one facepiece (one cartridge per side) for a complete filter change. Gerson's cartridge system is designed for quick installation with minimal interruption to the work process.

Vendor: Gerson | Model: GX70 | ASIN: B076N2JHLD | UPC: 044585714709 | Pack: 2-Pack (1 pair)
Protection Profile
| Hazard | GX70 Status | Notes |
|---|---|---|
| Non-oil solid particulates | Approved — P100 (99.97% min) | Silica dust, metal fume, lead dust, asbestos, wood dust, mold, construction debris |
| Oil-based aerosols | Approved — P-series (oil-proof) | Cutting fluid mist, machining coolants, oil spray — P100 covers both oil and non-oil aerosols |
| Gases and vapors | See product notes | For full gas/vapor compliance protection use a combination cartridge such as the Gerson G78 multi-gas cartridge |
The GX70 provides protection up to the APF of the facepiece: APF 10 for a half-face respirator, APF 50 for a full-face respirator. Always confirm the cartridge approval applies to your specific hazard. Consult the SDS and your industrial hygienist for substance-specific guidance.
Key Features
| P100 — 99.97% Efficiency, Oil-Proof | NIOSH P100 is the highest particulate efficiency rating available for APR cartridges and filters — 99.97% minimum filtration efficiency against all solid and liquid aerosols, fully oil-proof with no maximum use time for oil aerosol environments. P100 exceeds both N95 (95%, non-oil only) and P95 (95%, oil-proof) in efficiency. For lead abatement, asbestos, beryllium, silica in high-concentration environments, and oil mist applications, P100 is the appropriate specification. |
| Full and Half Face Compatibility | The GX70 is compatible with Gerson's cartridge-based half-face and full-face respirators. Operations running multiple Gerson facepiece types can stock a single cartridge SKU. Protection level is determined by the facepiece APF — the same GX70 cartridge delivers APF 10 in a half-mask and APF 50 in a full-face facepiece. |
| 2-Pack — 1 Complete Filter Change | Each 2-pack contains one pair of cartridges — exactly the quantity needed for a single complete filter change on one facepiece. Ordering by the pair reduces over-stocking and simplifies scheduled replacement tracking. At $13.59 per pair, the GX70 is a cost-effective P100 option for regular cartridge programs compared to multi-gas combination cartridges where gas protection is not required. |
| Construction and Industrial Use | Designed for the demands of construction, demolition, renovation, and manufacturing environments. Gerson's cartridge connection system allows quick replacement in the field without tools. For construction site silica and lead programs (OSHA 1926.1153 and 1926.62) where frequent filter changes and ease of use in active jobsite conditions are priorities, the GX70's straightforward design supports compliance without complexity. |
Common Applications
| Application | Why GX70 |
|---|---|
| Concrete cutting, grinding, and drilling (silica) | OSHA silica standard requires N95 minimum; P100 provides greater protection margin in high-exposure tasks |
| Lead paint removal and abatement | OSHA lead standards (29 CFR 1910.1025 / 1926.62) require P100 at certain concentrations; GX70 meets this requirement |
| Welding and metal cutting (fume) | P100 captures metal oxide welding fume including manganese, chromium, and other hazardous metal fume components |
| Machining with oil-based cutting fluids | P-series required for oil aerosol environments; P100 provides maximum efficiency for fine oil mist |
| Asbestos abatement and renovation | OSHA asbestos standards (29 CFR 1910.1001 / 1926.1101) require P100 for applicable exposure levels |
| General heavy-dust construction | Demolition, drywall, roofing, masonry — high particulate loading environments where P100's efficiency margin over N95 provides additional protection confidence |
GX70 vs. Other Gerson Filter Options
| Model | Protection | Best For |
|---|---|---|
| GX70 (this product) | P100 particulate | Construction, lead, silica, welding fume, machining — particulate-only environments |
| Gerson XP100 | P100 + nuisance OV/AG | Same P100 particulate with background odor relief — compact pancake design |
| Gerson G78 | P100 + full multi-gas (OV, NH3, SO2, HCl, HF, H2S, HCHO, Cl2, ClO2, methylamine) | Chemical, lab, wastewater, multi-hazard environments requiring full gas/vapor compliance |
Frequently Asked Questions
What Gerson facepieces are compatible with the GX70?
The GX70 is designed for Gerson's cartridge-based half-face and full-face respirators. Confirm compatibility with your specific Gerson facepiece model against Gerson's published compatibility data before use in a compliance respiratory protection program. Facepiece and cartridge compatibility must be manufacturer-confirmed under OSHA 1910.134.
Is P100 required for silica, or is N95 sufficient?
OSHA's respirable crystalline silica standards (29 CFR 1910.1053 general industry; 29 CFR 1926.1153 construction) require at minimum a half-mask APR with an N95 or better filter. Both N95 and P100 satisfy the minimum requirement. P100 provides a greater efficiency margin (99.97% vs. 95%) which is preferred in high-exposure operations like dry cutting, jackhammering, and confined masonry work where silica concentrations can spike significantly above the action level. Many industrial hygiene programs specify P100 for silica as a conservative default. Confirm your specific exposure levels via air monitoring and document the respirator selection in your written program per 1910.134.
How many cartridges are in a GX70 2-pack?
The GX70 2-pack contains 2 cartridges — one pair, sufficient to completely equip one Gerson half-face or full-face facepiece (one cartridge per port). Always install and replace both cartridges simultaneously. Replacing only one cartridge creates asymmetric breathing resistance across the facepiece and may indicate a non-compliant configuration. Browse respirator filters and cartridges for replacement ordering.
When should I replace GX70 cartridges?
Replace GX70 cartridges when breathing resistance increases noticeably during inhalation, when cartridges are physically damaged, or when they become wetted by liquid (wetting degrades P100 filter media performance). Particulate filters do not have a time-based service life under dry conditions — replacement is driven by loading (breathing resistance). In heavy construction dust or oil mist environments, daily or shift-based replacement may be appropriate. Document the replacement schedule in your written respiratory protection program per OSHA 1910.134(d)(3)(iii).
Can I use the GX70 for lead paint abatement?
Yes. OSHA's lead standards (29 CFR 1910.1025 general industry; 29 CFR 1926.62 construction) require a P100 filter (or equivalent) when lead concentrations are at or above the action level (50 µg/m³ TWA) but below 500 µg/m³. The GX70 P100 rating meets this requirement with a Gerson half-face respirator. Above 500 µg/m³, a full-face APR (APF 50) or PAPR is required — using the GX70 with a Gerson full-face respirator achieves APF 50. Conduct air monitoring to confirm exposure levels and document respirator selection in the written program per 1910.134.
What is the difference between the GX70 and the Gerson XP100?
Both the GX70 and the Gerson XP100 are P100 particulate filters for Gerson respirators. The XP100 uses a compact pancake (flat disc) form factor and includes nuisance-level organic vapor and acid gas relief via activated carbon. The GX70 is a standard cartridge form factor. For environments where background organic vapor odors are a nuisance concern, the XP100's activated carbon layer provides comfort relief that the GX70 may not. For pure particulate environments without vapor concerns, either product provides equivalent P100 filtration at different price points and form factors.

I can easily smell wood dust through these
I bought these because I struggled to find replacements for the wafer like filters that came with my Gerson mask. I use a respirator mask for woodworking as I am very dust sensitive. I can easily and instantly small dust through these filters, enough to trigger my asthma.
