Foldable construction filtering respirator 3M 9001V KN90 with exhalation valve

The model is equipped with an effective filter and an exhalation valve, making it an excellent choice for intensive work in dusty rooms and open construction sites. This filtering dust respirator is designed with adult users' anthropometry in mind, ensuring comfort throughout the shift.

KN90 level certification in China ensures filtering efficiency of non-oil particles of at least 90%.

The integrated exhalation valve reduces the buildup of hot air and moisture under the mask, facilitating breathing and preventing fogging of safety glasses.

The respirator folds easily in half, allowing it to be conveniently carried in a workwear pocket. Individual packaging (if available) maintains the product's hygiene until the moment of use.

The adjustable nose clip and elastic loops ensure an airtight fit, minimizing the risk of unfiltered air intake along the edges.

The low-profile design does not restrict the field of vision and combines perfectly with other personal protective equipment (helmets, headphones, glasses).

The 3M 9001V is a budget solution for protection against coarse non-toxic construction dust: plaster, brick chips, drywall, cement powder, sawdust. The KN90 class corresponds approximately to the P1/FFP1 level by European classification. The valve reduces glass fogging and facilitates breathing during physical work. The foldable design is pocket-friendly.

KN90 is not equivalent to FFP2 or FFP3. When working with fine toxic dust (quartz, asbestos, welding smoke, metals), use 3M 8822 (FFP2 NR D) or 3M 9332 (FFP3). For multi-hour daily use, the 6000 or 7500 series reusable half masks are more cost-effective.

The 3M 9001V compliant with KN90 (≈P1/FFP1), which is lower than the FFP2 of the 3M 8822 and 3M 8210. The 9001V is optimal as an economical replacement for simple 'petals' where FFP2/FFP3 is not regulatory required: household repairs, one-time construction operations with non-toxic coarse dust.
