HANUU Gas Masks Survival Nuclear and Chemical, Gas Mask with 40mm Activated Carbon Filter

This unit fits my needs perfectly (woodworking and some painting). I wear glasses, so the seal is a bit compromised, but the air is under higher pressure around my face. Therefore, I'm not worried about the airborne particles I am dealing with. The mask pushes my glasses against my face - It eventually leads to some minor discomfort. I am very pleased since it was at the price point I was looking for.

I wrote a review where charger quit after a week. I went and bought a universal adjustable voltage charger. Working weel

Mask is very small and would not cover my face properly and would ride up on my chin breaking the air seal continuously. Not enough fresh air being blown into mask even at high setting. I tried using it for grinding jobs I do and when I would really start working and exerting the air flow was just not powerful enough. My cheap 3M mask with only a couple of filters with no powered fresh air pump I was replacing provided much better air flow. You have to run it on high setting to even think of using it for real work. At the high setting the air pump did not even work for an hour after full charging. Probably more like 30 minutes with the higher air flow and it was limited flow the last 30 minutes before totally discharging. Battery took well over 3 hours to recharge and by the time it was fully charged I had strapped on my cheap 3M mask with only filters and completed the grueling 4 hour grinding job before the battery had even recharged. I do not have that kind of time to wait for the recharging time. Returned it and will go back to the cheap 3M mask from Lowes. The mask with air assist may work with short and non physical jobs and persons with small heads and faces, but I was not satisfied and felt suffocated the few times it would stay on my face and chin and not ride up. Additionally it has no room for glasses wearers and with my grinding jobs I need hearing protection with muff type units and it would not fit my ears properly because of the location of the straps on the mask. My hearing was compromised from the loud grinders having no hearing protection possible with the mask, and that was the last straw. If you want real air assist masks be ready to spend some real money for the real ones that actually work.

I was disappointed with the HANUU PAPR system. The overall design feels bulky and awkward, making it hard to wear comfortably for extended periods. The mask doesn’t seal well, which defeats the purpose of a powered respirator, and the blower unit feels cheap with weak airflow that doesn’t maintain good pressure or coverage. For something designed to protect your breathing in hazardous environments, I expected more. Build quality and reliability just aren’t there. I wouldn’t recommend this unless it’s for extremely light-duty or non-critical use. ⸻ Q&A: Q: Does the mask form a tight, reliable seal? A: No — the seal is inconsistent and loose, especially around the nose and chin. Q: How strong is the airflow from the respirator? A: The blower is underpowered and doesn’t create a noticeable positive-pressure environment. Q: Is it comfortable for long wear? A: Not really. It’s bulky and poorly balanced, making it uncomfortable for extended use.

zip ties are used to reinforce the connections so build quality could be *prettier* but it seems solid enough and the airflow is good and not TOO noisy.. filters are available in plenty but if you're just using them for viral protection you can simply fit your N95 mask over the intake and have a zero resistance experience for once..breathing easy and well protected..I actually find the full head piece LESS annoying than wearing just a paper/cloth mask but thats probably just me. view is clear and doesnt seem to fog easily.
