Unfortunately, due to a lack of reliable testing standards being presented, my confidence in this product is not there as I thought. Are there any reliable tests conducted? Regardless, this little AC81 could be worth the extra cash. Even knowing it needs improvement with proper certification or test data. The straps have an nice firm grip. Overall its good. Would have purchased again. was the product very much recommended than the Pro Blue other family members possessed?

I recently tried to use the Problue AC-81A Emergency mask during a camping trip but unfortunately the built-in LED light could not power on that night. I wish there is an option to manually activate additional lighting. I would also like it if the straps is more flexible and mold to the users head differently. It felt a little constraining on my face. it also did not get a full seal. It would also be helpful to have more certifications or safety ratings displayed prominently, I would like to know a bit more about the products safety and security. Overall the product is okay.

Alex Yeo –
I must say I’m somewhat satisfied – looks very much like what I’d expect from a quality respirator. Does this product fully meet the N95 standard? It would also be helpful if the straps has some type of swiveling joints to distribute the head pressure more evenly but other than the face felt a little tight.
Imran Hanafiah –
Thank you for sharing your thoughts on the Problue AC-81A Emergency Mask, Alex. The N95 standard is a requirement that states the mask must filter out at least 95% of airborne particles. Our Problue AC-81A Emergency Mask does meet this standard, as it has been certified by a third-party testing facility. Regarding the strap adjustments, I’ve taken note of your suggestion. We’ll consider implementing swiveling joints in future designs to distribute the head pressure more evenly. For the straps you currently have, we recommend adjusting them according to the user manual for optimal comfort.
Ahmad Chin –
Just got my Pro AC last week and I’m going to go camping this weekend. does it have interchangeable filters? I noticed a pretty big difference in quality and design, but my partner raves about this Pro AC product that supposedly lasts much longer.

Elise Lim –
Got my new emergency mask and was concerned initially about the material. Can you tell me more about the lifespan of the wearable part against harsh conditions? So far, I have been able to do a lot of back yard camping. And after 2 nights, the AC81 still felt perfectly fine. Maybe I will consider an upgraded version.
Imran Hanafiah –
Thank you for taking the time to share your experience with the Problue AC-81A Emergency mask. We’re glad to hear that it performed well in your camping trip, lasting for 2 nights without any issues. Our emergency masks are designed to be durable and can withstand various conditions, including outdoor use. As for the lifespan, we typically recommend replacing the filters every 6-12 months or sooner if exposed to extreme conditions. However, the lifespan of the wearable part itself can vary greatly depending on how often and in what conditions it’s used. We’ll take your feedback into consideration for future upgrades. If you have any other questions or concerns, feel free to ask!
Dylan Koh –
I love the compact design and the filter is really effective. However, the breathing valve could be sturdier.
Ewan Leong –
Had my first disaster preparedness training and this is one of the most commonly recommended masks! This Problue AC did exceed my expectations, sturdy quality, fine details, especially the face seal is good, and works well even when my face is a bit sweaty. My wife also tried on the mask and it fit pretty well. It is not bulky so I think it’s going to be comfortable even for long periods of wear.
Maya Huang –
This emergency mask serves its purpose alright but I have some doubts about the effectiveness in hazardous environments. Is the lens tamper-proof or easy to replace? Considering the price, I’ve been having good experiences with the mask so far.
Imran Hanafiah –
Thank you for sharing your feedback, Maya. The lens on the Problue AC-81A Emergency Mask is designed to be secure and resistant to tampering. However, if the lens does need to be replaced for any reason, it is easily removable and can be replaced with a new one. If you have any further concerns or questions, we’re here to help.

How long does the carbon filter last before needing to be replaced?

We recommend replacing the filter immediately after each use to ensure optimal performance and safety. If you have any further questions or concerns, please don’t hesitate to reach out. We’d be happy to help. For other users who may be experiencing similar questions, could you please share your thoughts and experiences with the product and its carbon filter replacement options?
