Nosk Invisible, Washable & Reusable Pollution Mask- Pack of 2

Product is of good quality. The seller included an extra pair of large size filters free of cost.Faced a different issue because of the nature of the product. Unlike the face masks which go over the nose, these are the penetrating type which need to be inserted into the nostrils. While in theory it should work, the tingling sensation caused me to sneeze a lot. Tried for two days but then had to give it up as the sense of irritation inside the nose was too much to be comfortable.

It was fantastic when i used first time fresh new filter. I was feeli g comfortable in breathing without any nise blick or throat choke. When i used on second day after washing, I felt comfortable but in the night I had very high heart pulse rate (120 ) and could not sleep for long time . Possibly because of very low oxygen in the blood due to low air in intake during the day .After I did some breathing exercise, my pulse rate cam down to 88 and then I could sleep . So not to use for long time . May be 2-3 hours is ok . So I rate only two stars

I use my bicycles as my main means of transport in Mumbai, and I don't stand up too well to pollution. So I have been through many, many pollution masks. The fabric masks have the inherent disadvantage of getting soaked with perspiration in the hot and humid climate of Mumbai, so I was finally driven to wearing one of those huge cartridge filter masks which make me look like I am from outer space. It doesn't really bother me, though, as long as I can keep cycling.But when I saw this pollution filtering device, the concept immediately struck me as one whose time had come. Firstly, it is discrete, and is hardly visible. Secondly, it is unaffected by perspiration. Thirdly, it allows me to breath quite freely. Fourth and very important, it is reusable.The box I received contained two medium sized filters, and one XL size. Possibly having an above average sized nose, the medium size did not fit me at all, and the XL just about fit. I wrote to the company informing them that the filters sent to me were unusable by me, and inquiring what I should do.Within a day, I received a well written reply, apologizing for the fact that the medium size did not fit me, and offering to send two XL filters to me by courier, free of cost. Not only that, the company went out of its way to explain to me with all details that the medium size usually fits most people, that they keep a database of persons whom it does not fit, and that I was only one of 11 persons out of several thousand whom the medium size did not fit. I was (and am) extremely impressed by the trouble and effort which the company took over one customer to ensure satisfaction, and specifically, to present the entire picture to me, instead of just offering to replace the product. I sent them my address, and within a day, received an sms that they had dispatched two XL pollution filters to me. I expect to receive them shortly. I find this sort of service outstanding. Seems like a company you can trust.As far as the product is concerned, I have already set out some of its advantages above. The XL seems to be effective, but it is only after more extensive use under different conditions, that I will be able to comment on this more accurately, as also on its longevity. But given my present experience, I would definitely recommend giving this product a try.

I already used 3 types of nose invisible mask..among those this one did not give much merit for me. The problem what I facing with this product is its really itchy.. as its layer is very thin it will easily bend in the nose and started make you itchy disturbance after automatically you remove it away..I dont know how others felt but for it really felt uncomfortable..especially I was satisfied with using some other nose mask where its layer is thick and non bendable... Better buy after checking the pics --that is the layer is thin or thick type.. for me (Health Innovative World's 1St Invisible Anti-Pollutuion Pit Nose Mask) felt more comfortable because its thick and not itchy ... Just personal view

Good idea, a pollution mask without covering face. Unfortunately it just don't work, doesn't prevent polluted air to enter nose and lungs anyway. This rating is only for good seller support and feedback. Unfortunately these things can never help you in India where pollution level is above critical. I suggest you go for a normal face mask. Just because the product is certified and manufactured by Koreans doesn't mean it will make your life easier and solve all your problems.

I have had chronic sinus in delhi for an year or so. By the time I got to know that it is because of the air, I had been through a lot of medications, homeopathic, alopathic, ayurveda.The production of mucus in response to dry air and pollution were at the core of my problem. No branch of medicine addresses the cause of sinus. They treat the symptoms. They can't help you "stop the excessive mucus production". They can dry it out (pains even more), then can thin it out (for better drainage). But as long as I was exposed to Delhi's air, the problem just stayed.I couldn't use an N95 mask at my work place all the time for obvious reasons. This was my saving grace.This mask comes in a set of 2. One should be used for 4-5 hours, washed under lukewarm water and other one should be put on. Repeat this process.Its a great product.Its plug and play, so if you have a runny nose, you can unplug it, blow out in the sink and plug back in. (Nasofilter from IIT Delhi don't provide you with this function which is a big design flaw i believe)You can use this while running as well.If you live in a place like Delhi, I think its a must for outdoor activity.Another thing is that you might feel a bit dry inside your nose after a few hours of use. Thats normal. At night use a humidifier with essential oil in your room to maintain health of your nasal and sinus cavity tissues.
