An essential upgrade. Though I walk through the valley of the shadow of respiratory hazards, I fear no particles, for my Respro and my Pro-Seal are with me. RESPRO'NSE: Amen to that 😉 Thanks for your review. Much appreciated

The product is a great idea and works however it is starting to tear after a little less than a year. I hope since this is a new product respro remedies this and creates a product that lasts a lot longer.

The proseal should have come with the CE Conversion kit! Anyways, I ordered a standalone large proseal for my allergy mask and the proseal takes about a day to "break in". Once broken in, it really makes it easier to breathe through the more restrictive filters! I have never worn a real respirator device before, but I assume this is the missing link. It seals and contours the face very well and only allows you to breathe through the filter / valves only!

Unfortunately, I'm allergic to whatever material it is made off. (I'm allergic to polyisoprene, or 'synthetic latex', as well as DEHP, thats my best guess as to what I'm reacting to). RESPRO'NSE: Please send an email to our CS team to see if they can help you with this.

in my opinion, one of the best add-ons, especially for the CINQRO and my face type (round and fat as a potato), it does a hell of a job, with keeping away the Filter from my Skin, so the Filter doesn't get that wet, when wearing the Mask for a longer time. In double the Seal Pro gives a much, much better sealing around the edge compared to the Filter itself fixed to the Skin (Especially right under the Eyes) RESPRO'NSE: Thank you for taking the time to write your review. We are very happy to hear the Pro-seal® is working well for you.

I bought one of these for my Ultralight, both XL, the nose peak sticks up about 1/2 inch above the mask, it stretches the masks fabric so you can see the holes near the powa elite valves clearly and basically ruins the mask and looks awful and does not feel comfortable, yet it fits my Techno+ perfectly. This feels like its not designed for the ultralight at all sadly.

Really happy with the Proseal addition to my Ultralight and Allergy masks. Really helps seal the mask to my face under all conditions, especially with the fact that I have to shave often and stubble can interfere with the seal without the Proseal. It also helps the mask fit me better as the XL mask is just a bit big. And I could not be happier with the level of customer service. They have responded to questions quickly despite the time difference to Vancouver Canada. They have been very helpful and the masks are helping me immensely when dealing with dust mite and grass allergies; work, working out in the gym, running, even running races with a mask on. And with fire season coming and constant smoke in the air expected, I am totally ready!

Respro’nse: “Thanks for your review Richard. Very happy to hear the Proseal is working well for you. Great to get the feedback”

Bought my Ultralight (black)in 2015 and after using it for 2 years. i just upgraded it with the pro-seal now the filter don’t stick to the face when working out - a great add on to the the mask

Harrison, Pure genius! Inverting the Pro Seal at the top did the trick, and actually makes for a more comfortable fit. Don’t know why I didn’t think of it. Thanks for your thoughtful, detailed replies to my questions . Best customer Service on the Planet. Alan

I live in a rural area and work in a big city, so I’m unused to exhaust smells. The mask (with the Pro-seal fitted) has exceeded my expectations in transforming my commute experience. The railway here runs highly polluting 2-stroke diesels and the air quality in the major stations is horrendous. Also, more often than not, the cars reek of diesel fumes and stench (as the A/C system sometimes suck external air into the train cars or a window is poorly sealed / left open). Another pleasant aspect of wearing the mask in the train is that it filters out aggressive smells of perfumes, cigarettes and food. I find myself wearing the mask (ultralight) for the entire duration of my commute (~2 hours), including walking in the street in a hot middle eastern climate. I have also recommended it to friend of mine who does the same commute, and he bought one as well, so good job with your product

RESPRO’NSE: Thanks so much for taking the time to let us know about your environment and how your Respro® Mask works for you. Much appreciated

The Pro-Seal is really good and protects even better from the pollution since there is less chance for the air to pass around the sides of the mask.
