These Activated Carbon Filters were designed for use in areas with heavy smog and can be inserted inside a pocket of your homemade mask. They will provide better protection than standard fabric alone and should be replaced about every 5 days, although many people report using them for up to 10 days.
Initially there was some difficulty getting the the filter inside my masks, but, now I fold it in half on the length side & insert it, then with my fingers unfold the filter. Fits perfectly in my masks.
They shipped so fast great quality I will definitely be ordering again! Thank you
Great addition for added protection to my masks
Works great! Makes me feel much safer with one in my mask. Still easy to breathe with one in, no fuss.
I love these filters. Make a huge difference. Ordering more!
Nice high quality filters. It wasn't easy to slip it properly into my pleated surgical style mask, but once I got it in, it was great!I'm sure it would be much easier in other mask styles.
The inserts seem to work really well on my homemade masks....I have sewn my masks with an additional pocket just for an insert to be added.
Fits great inside of my masks
So glad to have these! My husband & I are in the high risk range so the inserts give us another layer of protection.
My order was accurate and arrived when expected.
Nice filters. Make cloth masks seem a little more effective. Quick service.
This piece meets my expectations; I haven’t had a chance to try out the filter yet.
The products are excellent . They arrived in a timely manner.
I was hesitant to purchase due to so many fake sites. I called the number and spoke to a real person who answered my questions. Great company
Thank you for a great product. Easy to attach and made in the USA
I’m making masks for my mom. Hopefully she will like them
Quick, easy, so very pleased with this product. Got elastics, nose bars, filters! Definitely recommend .
Very good quality filter
