First, The service was fantastic! Never have i gotten a more detailed receipt than the one this company sent. I have yet to really use these in the "real world" but, I do see how they could work. The purchase is intended to allow me to ride my bike in a pollen filled area that i have moved. Also, my hope is to filter some of the strong odors in my workplace. Will update after actual use.
Excellent service, very timely.
Product size runs very small. I have a small nose and size small is likely for children not small adult. I measured as directed but should have bought medium. I used immediately at Dept. Store and perfume odor when right around filter, no protection from odors. Maybe better for dust and pollen. Same in grocery store aisle with detergents. If put too far in nostril will cause pain and sinus draining.
Disadvantages: Too small even having measured width of nostrils. Once inside nose they are too small as inside of nostril is larger than the outside opening. Next time will get medium. Need for 16hr plane trip, will use charcoal mask on top.
I started with the trial pack to make sure i knew what size i needed. shipping was very fast and found that they really work. I live in an area where there are high allergies....these definitely work for me.
Advantages: Reusable upto 3 days...prevent allergy triggers when seasons are high...shipping was fast!
Disadvantages: Filters-only purchases not available...can be pricey for people who suffer all year round allergies, or live in high allergy cities. Not available in stores.
I purchased a trial pack, because I wanted to have some to share, since the fires in California were so bad. The small fits me perfect and they are quite comfortable to wear. I haven’t actually had a chance to try them out for actual use, because the fire were put out and the rain came just before the package came.
