I suffer from severe fragrance allergies and MCS (Multiple Chemical Sensitivity); when exposed, I have anaphylactic reactions and as such, have to be hyper-vigilant about my environment. The Ultramasx allows me to be in spaces I wouldn't otherwise tolerate—here, l attended a Diwali celebration where many sources of fragrance were present and the mask completely protected me. I am so grateful and hopeful that others will be able to enjoy being able to go places and do things that were otherwise o...

Always satisfied with my purchase from Ultra, one of best in the business!

As a person with an immunosuppressive disorder, the ultra mask is very important to me. It provides me protection in places where I wouldn’t otherwise feel safe. I appreciate the comfort and good fit.

I am a person with a severe autoimmune disease I take treatment for every day. I have only recently been approved to be vaccinated. Unexpectedly, I had to go into the hospital and it was terrifying, because of the danger of being exposed to COVID-19. I wore my Ultramasx UltraOne the whole time, and it was amazing. The battery life was great between USB charges. The recirculating air flow was key to being able to wear it day and night. Knowing the 4 stage filter was there gave me real peace...

A lot of people are asking where can they get one

the white mask is exactly the same as the black one, it comes with a deeper face seal as well as the standard one, and plenty of spares. For the rest you can refer to my review of the black mask. I forgot to mention the fan which is great and prevents the build-up of carbon dioxide: a potential risk in perfectly sealed masks like this one. But I breathe very well when I'm wearing, often even without the fan. Sometimes I measure my oxygen levels and they're perfect. I hope these masks will be in ...

I have tried all the high quality masks on the market and, after very careful analysis and consideration (I have waited several months to write this review) I have to say I feel the safest with this one and I use it in the riskiest situations. The deeper face seal fits me perfectly which means the air I breathe when wearing the ultramasx is completely filtered by the HEPA filter (with the possible exception of whatever manages to penetrate the air exhaust which is likely negligible). It also mea...

I wore this mask to travel. At the airport and all during my flight. So nice to be able to breathe fresh air the whole time!

One of the best products I have used in recent times, well deserved applause for UltraMasx UltraOne.

Brilliant Product! Superb Innovation! Very Comfortable! Highly Recommended!

This mask has been a life saver for me. The fan and near excellent face seal has made wearing a mask bearable, especially at work. The company also has excellent customer service!

The last one I bought, stola working, so i wrote to the support, i explained, what happens and they send me a replacement. Super satisfied! I would buy again for sure!

the ultramasx has improved my o2 intake into my body allowing my machine to perform more efficiently at night because ive been able to lower it almost in half and safely. when forced to restrict air flow that my body and organs need to survive, i choose this masx 110% AND so does everyone i know. highly reccomended.

Bought these for myself and my better half. They are awesome for running around town. We can breath easily thanks to the powered fans. Plus my wife loves the color choices. Highly recommended!

I've never had a mask that doesn't fog up my glasses.This is amazing i suggest to all. Also, the customer service is fantastic. GAT

Works way better then the original

I love my mask. Works great even layered up.

I love this masx. I bought it mostly to use while snowboarding. I'll have to review it for snow sports, for those interested. First off, it's really nice to have something that breathes. That being said, the moisture build-up inside the masx is intense. I actually removed the foam from the bottom and some moisture drains from the bottom. Secondly, I have to move the masx to hydrate and sometimes to blow my nose. That doesn't disturb the straps, but it DOES disturb the silicon face plate. That no...

I wear this on the NYC subway to and from work every day on my hour commute. It’s the only thing that truly makes me feel safe in a closed car where no one adheres to social distancing. Thank goodness for this mask.

It's not just that this is a excellently designed mask that makes it worth the price, but the company's service seals the deal. I had a problem with the order I had received so I contacted their customer service. Within two days, I had a replacement mask shipped to me at no cost or any more hassle than a couple of emails. I love it when a company stands behind their product. UltraOne fulfilled all my criteria for the perfect mask: I was looking for top-notch air filtration (KN100 filtration...
