Honeywell North 5400 Series Niosh-Approved Full Facepiece Respirator, Med/Large (54001)

Some information that may help visualize the sizing based off of my own size - I am 5’9” and 160 Lbs. I typically wear a size large for a full helmet that has the foam padding inserts.Even though this item states it’s a size small it seemed to fit just fine around my face, including not seeming to compromise the seal around my beard. The weight does become noticeable after a bit, but is not an issue for brief periods of time. Longer durations of wearing a full face mask will always feel as if it is a chore to wear but this masks comfort seems to be very reasonable.Be wary that this mask, while it can have filters applied to protect from viral particulate, does come equipped with an out-valve which is there to assist you in exhaling with less exertion. I would recommend reading on cdc guidelines for masks with breathing valves for exhaling, as this mask seems to not filter your exhale which means if you are a carrier of a virus you may still be capable of spreading particles in the air.I personally would like to try the PAPR modification for this mask, but due to covid’s ongoing severity, that product seems to be offered to those who are verified health care providers exclusively, or anyone else that seems to be working positions in response to covid that are in high risk situations.I purchased another full face mask before this one, but this one is what I kept and felt comfortable and safe wearing. The previous mask I returned and will also be leaving a review for after posting this review.I honestly am not entirely sure what the “thickness” category encompasses entirely, but this mask does not seem to be made flimsily or cheaply. I don’t think we’re getting a tempered glass visor here, but it seems respectably durable and put together. Just take care of it properly.

Pros: I like this mask, it is very well made, affordable, and seals better than any respirator I have used in the past (AO Safety and 3M). It is however the first full face version I have used. The mouth piece has a seperate face seal and valves to prevent fogging. I have a beard and this seals the best of any device I have used, only minor leaking through the beard when plugging the filters. This mask also has the best functioning straps I have ever used, they hold tight all day, are easy to pull, and easy to release.Cons: The clear tearoffs were not included in the package and they were specifically called out as included in the description for the listing. I instead purchased 3M tearoffs and trimmed them to fit. There is an annoying "pop" when first exhaling, which is accompanied by increased pressure inside the mask, as if there is some minimum pressure that needs to build up prior to the exhaust port opening. The amount of pressure required to overcome this valve is much more pronounced than other respirators I have used, and actually pushes the mask away from my face, but not to the point of leaking. Also, wearing this mask for several hours makes my neck hurt because the front of the mask is heavy due to the canister/filters.Other thoughts: I would like to try a 3M or another brand of full face mask to see how they compare, however I do recommend this item, it works great.

My wife is 5 ft tall, and I purchased this specific product because it was the only one "Small Size" published in Amazon, but unfortunately, I have received the wrong size: M/L instead of Small. In the description, is clearly mentioned: "Honeywell North 5400 Series Niosh-Approved Full-Facepiece Respirator, Small (54001S)"... and additionally, double-checking the received catalog, the Manufacturer P/N for Small Size is precisely what is shown in the publication between parentheses. This ultimately confuses people.Note the same as another reviewer recently said: "Incorrect Listing." "Please change the listing to reflect the product accurately. At a time like this pandemic, a customer's life may depend on a properly fitted mask."

Incorrect Listing: The main headline listing states this is the small (54001S) mask, whereas the details state this is the Med/large (54001) mask. What arrives is the Med/large mask. Unfortunately I need the small size.Please change the listing to accurately reflect the product. At a time like this pandemic, a customer’s life may depend on a properly fitted mask.

My husband is extremely picky but actually loves this mask. It does not fog and he said it was comfortable, if you can please him; it's perfect.

Love these. Great for what's going on now!

Works amazing for demoing a lathe and plaster room!!

I got my resiperator just in time for harvest use but it did not come with filters. No where in the ad did it say filters were not included.sucks! so buy filters if you plan on using this thing.Oh three stars becasue of price. other places charge 2 times as much. shipping was fast too.
