CLENARE Large Round Invisible Body Nasal Filter for Defense Against Air Pollution, Dust, Pollen and Allergies

Very delicate. If we can use delicately really this is very useful. I have been using this item for one year.

easy to wear and barely noticeable. there is some air movement restriction and you can't do any brisk physical activity while wearing these. but that's true for most filters.

Worst product i ever received

I was pretty much sceptical whether this would work or not but the choking pollution of Mumbai forced me to try it. I'm always ready to try new things. At first, I felt so blissful to take in the less smoke from exhausts while travelling. For people travelling on the bike daily, this is a must. I can still smell pollution and dirt while riding on the bike but the intensity of it is lesser. For the fact due to filters, you are actually breathing less air. One fine day when I missed wearing the filters that day I realised the bliss of it when I breathed so much pollution. The next day I just had to wear it. The membrane is washable in my experience. Overall I could say I'm 80% satisfied with the product as in it does 80% job of what I expected from a nasal filter. Your nose and throat will thank you. If the membrane was a bit thicker and if I couldn't smell even a bit of polluted air or dust then I would be 100% satisfied.

Not usable as shown in images

Not very comfortable in the beginning but gets adjusted later on. You will get rid of Sneezing/throat irritation with in 2 to 3 days to the maximum extent.

This filter efficiency against pm 2.5 is 80% as it states. In a place like Delhi filter becomes choked easily in about less than 7-8 hours and needs to be changed frequently to be able to breathe freely

Look wise product is good. When we wear feel difficult to breath. Not useful.
