Anti-Dust Nose Protection - Personal Protective Facemask Added Protection - Dustproof Breathable Filters for Woodworking, Sanding Protection & Construction - Black (30 Pack)

First, they say in the description these are for larger particles like dust. They do not work on fumes. As for the size, I have smaller nostrils and they do fit me good. When you put something in your nose, you will restrict airflow. But these don't restrict them that much. I have asthma and I can breathe just fine. I do have bad allergies. Highly allergic to dust amongst other things. And I do get allergy shots. I love to use these dusting the house, working in the garden, and mowing the grass. These aren't HEPA rated but I feel a huge difference when I use them. Like 90% better. If I forget to use these doing the tasks noted above I am in bed for at least 3 days. I highly recommend these for appropriate applications.

Husband swears that these are great for keeping the dust out of his nose and helps with his allergies (I think this is in his head).

The fact that effective, easily manufactured, and portable products like these weren't distributed to every citizen throughout the COVID-19 pandemic, and vaccines and ridiculous stimulus checks were, is worthy of deep consideration as to the true intentions of global authority figures. Why were these not in everyone's mailbox or advertised in our environment? Why is no one communicating publicity about the widespread immune system issues clearly evident in the general population?

I work in facilities/maintenance in a very old and incredibly dusty warehouse. I am slogging through piles of dust every day and have had to buy a nose and sinus cleaner to get the dust out after work everyday. It is disgusting. These things are perfect for what I do. Normal masks don't fit well or get really hot and annoying to wear especially since I do a lot of physical work which makes me sweat buckets. Or they just don't seal well and dust gets in anyways. I will say, they take some getting use to, and can be very suffocating feeling at first. Definitely takes an adjustment. I've had to consciously remind myself I can breathe through them. When I first put them in I caught myself breathing through my mouth. Honestly, it's better than blowing black and blue boogies everyday. Kind of glad they're disposable too since they can get a little snotty hahaha.

I purchased these to use when conducting prescribed fires here in SW FLA. After using them on a few fires, I have noticed a marked difference in the amount of ash and particles that do not make their way into my nasal passages. Normally without any sort of filter or respirator I end up blowing large amounts of black gunk from my nose at the end of a fire, but when using these I accumulate next to nothing in my nose. Respirators tend to be too bulky and when conducting growing season burns it's too damn hot to have a large apparatus on your face - these are far less invasive and very comfortable to wear.
