3M Secure Click D7N11 N95 Particulate Filter Overview
The 3M Secure Click D7N11 N95 Particulate Filter is a NIOSH-approved N95 filter for the 3M Secure Click platform, sold in a 20-pack (20 individual elements, equal to 10 pairs). It captures at least 95% of non-oil airborne particles — construction dust, wood dust, agricultural particulate, pollen — using the Secure Click push-to-connect mount that seats with an audible click on HF-800 half-face and FF-800 full-face respirators.
As the 3M D7N11 20 pack filters, this is a genuine Secure Click N95 particulate filter HF-800 FF-800 option. Note that this is a 3M Secure Click filter not for bayonet respirators — a true N95 non-oil particulate filter bulk pack using the Secure Click push-to-connect filter interface.
It is N-rated only, not oil-proof, and provides no gas or vapor protection. For oil-based mists or P100 efficiency, see the Secure Click D7P71 (P95) or D3091 (P100). Review the rating system in respirator filter types explained and browse the 3M filters and cartridges collection.
Where the D7N11 Fits
| Hazard | D7N11 Fit | Buyer guidance |
|---|---|---|
| Construction / wood / agricultural dust | Good fit | N95 captures ≥95% of non-oil particles. |
| Oil-based mists / aerosols | Not suitable | Use the P95 D7P71 or P100 D3091 instead. |
| Silica, lead, asbestos | P100 preferred | Use the D3091 for these substance-specific standards. |
| Gas or vapor present | Not suitable | Use a Secure Click gas or combination cartridge. |
| 3M bayonet respirator (6000/7500/7800S) | Incompatible | Use a bayonet-mount filter, not this SKU. |
The D7N11 is a non-oil particulate filter only and provides no gas, vapor, or oil-mist protection, and no filter adds oxygen. It fits only the 3M Secure Click platform — do not attempt to install it on a bayonet respirator. Oxygen-deficient, unknown, and IDLH atmospheres require supplied air, an SCBA, or another solution specified by a qualified safety professional, not an air-purifying filter like this one. For substance-specific hazards requiring P100 (silica, lead, asbestos), use the Secure Click D3091. See P100 vs N95 and best respirator for silica dust.
Pros & Cons
Pros
- 20-pack (10 pairs) lowers per-unit cost
- NIOSH N95: ≥95% non-oil capture
- Fast Secure Click push-to-connect mount
- Soft-pad housing for comfortable wear
- Compatible with HF-800 and FF-800
Cons
- N-rated only; not suitable for oil mists
- Not P100; not for silica, lead, asbestos programs
- Fits only HF-800/FF-800, not bayonet masks
- No gas or vapor protection
How It Compares
The D7N11 is a bulk N95 particulate filter. Weigh it against nearby Secure Click options:
| Filter | Class | Pack | Choose if |
|---|---|---|---|
| D7N11 (this page) | N95 (non-oil) | 20-pack | High-volume non-oil particulate, lowest per-unit cost |
| D7P71 | P95 (oil-proof) | Pair | Oil-based aerosols present |
| D3071 | P95 | Pair | Lower-cost P95, same particulate work |
| D3091 | P100 | Pair | Silica, lead, asbestos — P100 required |
Choose the D7N11 for bulk non-oil particulate work, the D7P71 when oil mist is present, or the D3091 when your standard requires P100. See respirator cartridge color chart and how to choose a respirator cartridge.

Frequently Asked Questions
What is the 3M Secure Click D7N11 used for?
N95 non-oil particulate protection on 3M Secure Click HF-800 and FF-800 respirators — construction dust, wood dust, agricultural particulate, pollen, and general fine non-oil airborne particles. The 20-pack format suits programs with regular filter replacement needs.
Does the D7N11 fit 3M bayonet respirators?
No. The D7N11 uses the Secure Click push-to-connect mount and fits only HF-800 and FF-800 respirators. It will not attach to 3M bayonet respirators such as the 6000, 6500QL, 7500, 7800S, or FF-400 series.
Is the D7N11 N95 or P95?
N95, not P-rated. N-series filters capture at least 95% of non-oil airborne particles but are not rated for oil-based aerosols. For P-rated, oil-proof protection on Secure Click, use the D7P71 (P95) or D3091 (P100).
Can the D7N11 be used with oil-based mists?
No. The N-rating means the D7N11 is not tested or certified for oil aerosol environments, and using an N-rated filter around oil can degrade filtration performance. For oil mists, choose a P-rated Secure Click filter instead.
How many filters are in one pack of D7N11?
20 individual filter elements. Secure Click respirators use two filters at once, one per side, so 20 filters give you 10 complete filter change-outs per pack.
What is the difference between the D7N11 and the D3091?
The D7N11 is N95 (non-oil, at least 95% efficiency) sold as a 20-pack. The D3091 is P100 (oil-proof, at least 99.97% efficiency) sold per pair, and is the correct class for silica, lead, and asbestos. The D7N11 is the lower-cost bulk option where N95 is acceptable and oil is not present.
Is the D7N11 good for construction dust?
Yes, for general construction dust where N95 is the required class. For silica-generating work like concrete cutting or masonry grinding, confirm whether your substance-specific standard requires P100 — if it does, use the Secure Click D3091 instead.
Does the D7N11 protect against welding fume?
It captures non-oil particulate welding fume at the N95 level. Where a standard requires P100, use the D3091 instead, and for combined fume and gas exposure a combination cartridge is needed rather than a particulate-only filter.
Can I use the D7N11 on an FF-800 full-face respirator?
Yes. The FF-800 is a Secure Click full-face respirator, and the D7N11's push-to-connect mount seats onto it with an audible click confirming installation.
When should I replace the D7N11?
Replace it when it is damaged, torn, visibly soiled, or when breathing resistance increases noticeably, and follow the replacement schedule in your written respiratory protection program.
Should I buy the D7N11 or the D7P71?
Buy the D7N11 (20-pack, N95) for high-volume non-oil particulate work where you want the lowest per-unit cost. Buy the D7P71 (P95, per pair) when oil-based mists or aerosols are present, since N-rated filters are not tested for oil.
Is the D7N11 a hard-shell filter?
No, it uses a soft filter-pad housing, not the rigid hard-shell design of the D9093 series. The hard-shell Secure Click filters are P100 and suited to environments where filter damage from impact is a concern.
