What the Klein Tools 60507 N95 Replacement Filters Are

They are the NIOSH-approved N95 replacement filters for the Klein Tools 60506 N95 Reusable Face Mask, supplied as a 3-pack. Each captures at least 95% of non-oil airborne particulate — dust, sanding and cutting debris, and oil-free aerosols. The stand-out feature is the hook-and-loop attachment: the filter presses onto the mask and peels off by hand, so changes are quick and tool-free, and you keep the mask while swapping a low-cost filter. They also use an anti-fog design that helps keep safety glasses clearer.

Because these are N-class, they are non-oil filters — for oil mists or the higher P100 efficiency you would move to a P-series filter, such as Klein's 60245 P100 on the P100 half-mask, which is a separate, non-interchangeable line. As N95 filters they are for general non-oil dust where 95% meets the need. Our filter comparison and fit-testing guide help place them.

N95, Non-Oil, and the Hook-and-Loop Design

Two things define these filters. The first is the N95 class, and it is worth being precise about. N95 captures at least 95% of particulate, but the N means "not oil-resistant" — so these are for non-oil hazards: dust, wood and drywall debris, sanding and cutting particles, and oil-free aerosols. Klein rates them exactly that way. If your work throws oil mist — some machining, spraying and cutting fluids — an N-class filter is the wrong choice, and you move to an R or P filter that tolerates oil. Matching the letter to your hazard matters as much as matching the number.

The second is the hook-and-loop attachment, which is what makes the 60506-plus-60507 system convenient. Instead of twisting a cartridge or clipping a bayonet filter, you press the filter onto the mask and peel it off — a tool-free change that suits the reusable-mask model, where the mask lasts and the filter is the consumable. Paired with the anti-fog design that keeps safety glasses clearer, it makes for an easy, comfortable non-oil dust setup for trade and DIY work. Just keep the two truths in view: it is non-oil N95, and it protects only on the 60506 mask it is made for. Our respirator guide covers where an N95 fits.

Frequently Asked Questions

What mask do these filters fit?

The Klein Tools 60506 N95 Reusable Face Mask. The 60507 is the replacement filter for that mask, attaching with a hook-and-loop fastener. It is a replacement filter, not a respirator on its own — you need the 60506 mask to use it. It does not fit Klein's P100 half-mask respirators or other brands, which use their own filters, so match the filter to the mask you own.

What does N95 mean, and does it stop oil?

N95 means the filter captures at least 95% of airborne particulate — but the N stands for "not oil-resistant". So it is for non-oil particulate: dust, sanding debris, and oil-free aerosols, which is exactly how Klein rates it. It is not for oil mists or oil-based aerosols; those need an R-class or P-class filter. If your work involves oil mist, this N95 is the wrong class, and you would move to a P-series filter instead.

How does the hook-and-loop attachment work?

The filter attaches to the 60506 mask with a hook-and-loop (Velcro-style) fastener, so you press it on and peel it off by hand — no tools, no twisting a bayonet or clipping a cartridge. That makes filter changes quick and simple, which is part of the appeal of the reusable-mask-plus-filter design: you keep the mask and swap the low-cost filter. Make sure the filter is seated flat and fully attached before use so nothing bypasses it.

What is the anti-fog feature about?

The filters use an anti-fog design that helps reduce the fogging of safety glasses or goggles worn with the mask. Exhaled breath escaping upward is the usual cause of lens fog; a mask-and-filter set that manages that airflow keeps your eyewear clearer. For anyone who wears glasses over a mask on dusty work, less fogging is a genuine day-to-day comfort and safety benefit, since a fogged lens is its own hazard.

N95 or P100 — when do I need more?

N95 captures at least 95% of non-oil particulate; P100 captures at least 99.97% of both oil and non-oil. Choose the N95 60507 for general non-oil dust and debris where 95% meets your need. Step up to a P100 — such as Klein's 60245 P100 filter on the P100 half-mask — when your hazard involves oil aerosols, or when the substance or your workplace assessment calls for the higher 99.97% efficiency. Match the class to the hazard and its exposure limit.

How is this different from the Klein 60245 P100 filter?

They are different, non-interchangeable Klein lines. The 60507 is an N95 filter for the 60506 N95 reusable face mask; the 60245 is a P100 filter for Klein's P100 half-mask respirators (Cat. Nos. 60244 and 60246). Different class, different mask, different attachment. If you run the N95 reusable mask you need the 60507; if you run the P100 half-mask you need the 60245. Do not try to fit one to the other's mask.

Are these genuinely NIOSH-approved?

Yes — the 60507 is a NIOSH-approved N95 filter, and Klein lists it as NIOSH-rated. That matters: a respirator filter must be NIOSH-approved to be a legitimate respiratory protective device, and fitting a non-approved "compatible" filter to a mask voids the mask's certification. With the genuine Klein 60507 on the 60506 mask, you have an approved N95 assembly. Always keep to NIOSH-approved filters for the mask you own.

How many come in a pack, and how long do they last?

The 60507 is a 3-pack of filters. Service life depends on how heavily the filter loads with particulate — dust, sanding debris and the like — rather than a fixed hours figure. Change a filter on a noticeable rise in breathing resistance, on any damage or soiling, or on your workplace schedule, whichever comes first. In heavy dust they load faster, so a multi-pack keeps spares on hand for frequent changes.

Can I wash and reuse the filter?

No. The filter is a consumable — washing it soaks and damages the media and voids the NIOSH approval, so it no longer filters as rated. The mask is the reusable part; the filter is what you replace, which is the whole point of the hook-and-loop design. Replace a loaded, damaged or soiled filter rather than trying to clean it, and keep the mask itself clean per Klein's instructions.

Do I still need a fit test?

If you use it as workplace respiratory protection, yes — a tight-fitting respirator needs a fit test on the specific mask, before first use and annually, plus a user seal check each time you don it. The filter class does not change that: fit testing proves the mask seals to your face, and the seal is what makes the filtration count. Facial hair along the seal breaks it, so a clean-shaven seal is required for a tight-fitting respirator.

What is it good for?

Non-oil particulate work: general dust, sanding and cutting debris, drywall and wood dust, and other oil-free airborne particles, on the Klein 60506 reusable mask. It is a practical choice for DIY, remodelling and trade dust where an N95 mask meets the need and the easy hook-and-loop change and anti-fog design add convenience. Where oil mist or a higher efficiency class is involved, move to a P-series filter instead.

What does it not protect against?

Oil aerosols — it is a non-oil N-class filter — and any gas or vapour, since it is a particulate filter with no sorbent: no carbon monoxide, no solvent vapour. It cannot add oxygen, so it is no use in a low-oxygen space, and it must never be worn in an atmosphere immediately dangerous to life or health. It protects only as well as the mask seals, so a fit test and clean-shaven seal are prerequisites. It is a non-oil N95 particulate filter, and nothing more.
