As a person who has had asthma all my life, I appreciate being able to go outside and enjoy life even when the air quality isn't good. Note, however, these masks are ineffective against ozone.

5.0 out of 5 stars Never caught respiratory illness while wearing these during my pandemic clinicals

C.R. · January 20, 2025

X-ray tech here. Did my clincals during the pandemic when n95 masks were harder to get. I had stocked up on these early on, and didn't trust the Kn95 masks the hospital provided. Some were not to spec and people got sick. There just weren't enough n95's for them to provide at the time, and the Kn95s had to do, despite their sometimes questionable sourcing.I never caught covid/flu/head colds while doing my clincals. I wore these like a second face. I was taking x-rays of all kinds of positive testing people. All kinds of airborne and droplet precautioned rooms. All kinds of people actively coughing in my face while I was trying to get a board placed behind them (I also wore eye protection for the coughing in my face part.)Things are much better, and n95's are easier to get. The hospital will now only allow their provided n95s to be worn for safety reasons, but I still buy and wear these masks while in crowded high traffic places during cold and flu season, or during covid spikes. (Like at the crowed grocery store, or during holiday shopping)If these are helping to block tiny cold bugs for me, then these will block small dust and debris particles for sure. Wear these with confidence. Just make sure they form a tight seal on your face, and sadly no beards (breaks the seal and lets it all in.)The rubber straps on these seem older. They are harder to stretch to put on, and can break more easily if pulled to fast or just a little too far past my head. So that's been an issue with these.Also, these are n95s, they are not easy to breathe in while working hard, and they are tightly sealed to the face which will leave pressure marks at the end of a shift. Worth it.These are actually a life saver for me. My lungs can't handle illness, and with these masks they didn't really have to. I watched coworkers/classmates go down hard with illnesses, and I never had to miss a day. These definitely will block sawdust and drywall dust.

These are excellent masks. Just uncomfortable and poor fit because too small for my face. I didn't need them right away, I purchased them for a "what if" situation. Now I have a cold and don't want to infect my wife, just found out yesterday they are too small so I missed the return window. I am making them work until I can get the larger ones.these smaller ones would be great for a person aged 9 - 12 or a smaller adult.

5.0 out of 5 stars Best partical mask out there….

These 3M dust masks are the best…used them for years in manufacturing….great seal…snug fitting…adjustable clamp for around your nose….worth every penny when it comes to protection…using them now for my wood projects….these are the best period!!!!!!

These masks serve their purpose well when we must filter out smoke from Canadian fires.

These are authentic 3M 8210 masks. I wear these cutting grass. They work great. I am able to use about 4 times before the elastic bands break and I must discard.

Son incómodas a comparación de las kn95, estas de 3m son si quieres tener una máscara mas segura, lo que depende de tu día a día. Si tomara transporte público o vuelos en avión, también preferiría estas, y también las uso para el cine ya que nadie respeta el uso de mascarillas. Para todo lo demás uso kn95 o quirúrgicas, pues las kn95 son muy buenas máscaras. La diferencia con estas es la certificación, mientras las kn95 solo regula la filtración de partículas, las que tienen certificación NIOSH, regula tanto la filtración como el sello que hacen en tu cara. Es decir, aseguran que no importa si te mueves, agachas, etc etc, siempre hay un sello alrededor de tu cara para filtrar todas las particulas que entren.Por cierto, para los que USAMOS LENTES son una maravilla ya que al tener un puente de metal rígido con el que cierras y sellas bien la mascara con tu piel, no tengo problemas de que se empañen. Eso si, por el puente de metal los lentes como que "se suben" un poquito entonces luego hay que jugarle para acomodarlos bien, pero adios al no ver por estar empañados jajaja.OPINIÓN:Me imagino que lo que la mayoría quiere saber es si de verdad son originales. En mi caso lo fueron, los compre vendidos y enviados por Bolo lo que me dió mas confianza. Además, este producto trae una cosa que se llama SAFEGUARD de 3m, básicamente si le pones "safeguard 3m" en google te va a llevar a una página donde vas a ponerle unos números que traen en la caja, lo que te dirá si coinciden con el inventario de 3m para asegurarte que son originales. Además, el número de lote de la caja debe coincidir con el número de lote estampado en los cubrebocas.Para beneficio de todos, si compras estos cubrebocas, pon estos números en la página de 3m porque de esta manera quedan registrados, y si alguien estuviera falsificando las cajas, entonces al tener números repetidos, te estaría avisando que puede ser un producto falso, así que entre mas números se registren menor probabilidad de que nos toquen falsificaciones.Aún así, porque #ansiedad, les escribí a los de 3m porque la caja llega sin sello holográfico, el cual he visto pero en las cajas de estados unidos, así que escribí para preguntar, mande fotos de la caja y el producto y me respondieron que lo revisaron y que todo se ve en orden. Sobre el sello quizá sea por el país ya que yo he comprado otras mascarillas n95 en home depot y tampoco vienen selladas.Ahora, sobre la comodidad y eso, en definitiva estos cubrebocas aprietan MUCHO PERO MUCHO mas que otros, esto es porque la certificación que manejan es la NIOSH, esta certificación también revisa el AJUSTE del cubrebocas, a diferencia de la certificación china (como los kn95) que solo revisa la filtración de particulas pero no el ajuste. La NIOSH revisa tanto ajuste como filtración.El motivo de que aprieten un buen, es porque, si has visto gente con sus KN95 y se ve que no está completamente pegado a la piel o se hacen pliegues como cuando usas quirúrgicos, pues por ahí estas tanto esparciendo la enfermedad (si estás contagiado) así como por ahí esta entrando aire sin ser filtrado, por eso es que estos cubrebocas son muchisimo mas apretados. Se pueden volver molestos, en definitiva que si, pero creo que son mas seguros en especial si vas a estar tiempos prolongados en espacios cerrados, no los recomendaría para el uso diario, a menos que tu uso diario sea estar encerrado en alguna oficina sin mucha ventilación. Pero puede que te haga marquitas en el puente de la nariz, lo que puedes mejorar un poco usando cinta microporo, no puedes poner algo muy grueso porque entonces puedes alterar el sello que hace el cubrebocas con tu cara, pero con un poco de microporo si mejora la fricción en el puente de la nariz.Los elásticos: Si has comprado las n95 8511 de 3m también, los elásticos son completamente diferente, ya que esos son mas bien como un resorte, pero estas si son un tipo de banda elástica, al principio vas a sentir como que "afloja" muchísimo, pero no pasa nada, si mantienen su elasticidad, o al menos hasta ahora he usado 3 máscaras de este paquete y no he tenido problemas con esto, además de que soy muuuuuy cabezon.Eso si, dicen que normalmente al menos 1 mascarilla va a fallar su elástico, ya que parece que su diseño en donde se pega con la mascarilla no es tan bueno (dicen), hasta ahora no he tenido ese problema pero aún faltan 17 mascarillas mas, actualizaré este review si tengo ese problema. De todas maneras siempre llevo una kn95 extra, porque uno nunca sabe cuando necesita una más :v

Fake this time ! Bought original ones from the same link before 3 times !

D.C. · August 20, 2021

The media could not be loaded. I am buying this for the 4th time now . First 3 purchases were original and it was 2000 odd rupees per mask . When the prices got lowered last month I thought maybe they have reduced it with a dilemma in mind whether they will procure originals imported from Korea or not . To my surprise the two boxes in this purchase were fake . The mask is fake . The headloop is made of cotton where the original 8210 will have elastic rubber bands . Original 3M doesn't manufacture cotton banda all over the world . I am an airline pilot and I have used many 8210 in the past. I can clearly distinguish between the real and the fake ones . The nosepad is made of bad cushion . The mask cloth is weak and non woven . The cloth is welded into the mask . This is a cheap copy ! The boxes came tampered !! UNDERSTAND ONE THING .THIS PRODUCT HAS SURELY BEEN TAMPERED BY SOMEONE OUTSIDE BoloG DURING DELIVERY OR SOMTHING. I HAVE BOUGHT MASKS FROM THE SAME LINK AND REVEIVED ORIGINAL AUTHENTIC 3m 8210 in last 3 purchases . This us highly concerning for me during covid . People are cheating around . I am attaching a mask photo of this cheap and fake Masks as well as the original mask . Decide for yourself.

Excelente producto

Los use para fumigar, excelente producto.

This is a medical product- It HAS to be Hermetically sealed.

S.S. · April 28, 2021

Was a little surprised that the product arrived opened and with a small tag as a “seal” very similar to what you would get when you buy a loaf of bread. The quality of the product however is good... but in these time of covid, having a mask that may be contaminated- is not acceptable.

Original product

A. · June 21, 2021

it was fingers crossed when i saw the reviews before purchase, because i saw some said the product is not original, was not delivered in the right package/damaged package etc. However, i received it in original package with 3M instructions, verified the product in 3M site as well. It is a bit tight, but that is a good thing, because it has to be air tight around the edges where it makes contact with face. Just stretch the straps a little (without straining the joint with the mask) before use.
