    I’d done some online research on the testing of mask filter options and Filti popped up a few times with positive results. I bought the white Filti fabric and made patterns for my mask size and my sons. You could just cut a flat piece, or buy the pre-cut inserts or Filti masks, but I wanted to fit the curves of our hand sewn fitted masks. The Filti material is easy to sew by hand or machine. I fold the sewn filters in half, and pull through the the mask with a large safety pin. It’s been working well, and I feel better knowing there is extra protection in our masks. This time I’m going to buy the green fabric which makes it easier to tell the outward facing side of the filter material from the inward facing side.

    I have used this fabric for inserts for our extended family of all shapes and sizes. Having the ability to cut the fabric to insert into the different masks made for everybody is invaluable. It’s been working very well so far, and I am secure in knowing I’m doing the best I can for all of us in these times.
    Once cut, the insert is very easy to fit inside the pocket with almost any sewing tool to avoid overhandling.
    If I do need to order again, it will be the green fabric, as that makes it easier for everyone to know which side should face out.

    This material is top notch for use as an insertable filter inside a fabric mask with a pocket. Cut to fit – first make a paper pattern of the sewn edges of the pocket (which should encompass all areas of the mask through which you can breathe – or buy another mask). Then trace the pattern many times on the fabric, and cut.

    We tested this fabric, on its own (not inside a mask pocket):

    1. It holds water longer than 2 minutes (we stopped the test at that point) – with no drips at all, and not even tiny drops on the underside.

    2. We can’t blow out or even move a flame through it, and

    3. We can’t smell most smells (lemon, mint, rosemary, smoke) through it.

    I have been using filti material since the pandemic started. I make a cup style mask that everyone loves. You can breathe and talk through a filti mask. Plus I give each person one of filtis descriptions about N95 with their mask. I also use it as a liner for fancy masks. I purchase lovely breathable material line it with filti and people have a pretty mask that is also a N95. I appreciate that fact that it is made here in the USA as well.
    Love this material

    I am SO EXCITED to have found Filti face masks!
    They are very comfortable to wear, no pulling on the ears or slipping down past the nose.
    The air flow is incredible too, I do not have the “panic” that I have experienced with other face masks!
    I am in customer service and am much more confident in my job performance! I am not busy struggling with my mask during customer interactions and the communication seems much smoother.
    Thank you Filti!!!

    My sister and I have been sewing masks since February, for our families, friends, and others to help; in different sizes as needed – small to large sizes.
    A few weeks ago, my sister sent me some masks, including some FILTI material inserts she had cut from the FILTI material by-the-yards.
    FILTI is exactly the quality of this fabric I have been looking for!
    The quality is excellent, for safety, quality, and flexibility.
    All of my questions and help were carefully and quickly handled – thank you FILTI!!!

    My whole family uses the FILTI inserts, which we cut out ourselves from the rolls. I prepared packages of them before the kids went back to college. We started in April, after I had done some research on melt-blown and polypropylene fabrics. In this crazy COVID time, I feel good knowing that we have FILTI to help protect us. FILTI, we will continue to buy from you, as long as we need to keep ourselves safe. I also sent a batch to Europe, to my dad. THANK YOU!!!

  8. brian grieser

    I have been using Filtii inserts made from your company. I feel more at ease going out in public. I would like to clean the filters that I’ve replaced but the guidance I read using a pan of water, aluminum and placing them in a oven is not detailed enough for meto use. I would appreciate any clarification. Thanks,

  9. Ronne Robinson (verified owner)

    I have been purchasing Filti material since April & the level of confidence that I have in your product is 1000%!!!
    I have been cutting filter inserts for the cotton masks that I make & provide to my family – I have no doubts in my mind that Filti material is outstanding protection against Covid & I will continue to protect my children, my grandchildren & myself, with absolute surety that Filti will help keep us safe!!!
    This company also has the most outstanding customer service that I have ever encountered!

    I always include the MSDS sheet of the Filti fabric with all my masks. I started with the original white fabric until they came out with the green one, which had same properties but I swear was slightly thinner and not as “stiff” as the white, but one rep told me yes, and the other said no. I’ve made over 1000 masks with the Filti fabric I think after cutting and sewing them into my fabric masks, I can feel the difference. But I think they have also started making the white the same now. I think the green “sheds” a bit more because it is softer – I just use a sticky roller to pick up the fibrous threads off the fabric side of the mask; not a big deal. All the same, great product. I sew it as the second layer of my fabric masks. No need for a third layer, masks are still light enough yet sits well on face that it doesn’t flop around; breathable and doesn’t stick to your skin. I trust this product – great customer interaction plus they are offering other products for home too. Will continue to buy their products. Thank you for providing us!

    I have been sewing Filti in all of the masks I make for my family, friends, and co-workers. It is durable, easy to sew, easy to breathe through, and makes comfortable masks. I am very thankful to have found this product.

  12. Ericka Mays (verified owner)

    This is the best product for these times. The people are lovely to work with and very helpful and the site is easy to navigate. They make it very easy to buy. This is my 3rd or 4th order for filter material for our masks and we’ll always come back.

  13. Billi Waag

    Really enjoyed your site. Thank you for writing this. You have a lifetime fan.

  14. Sheila G (verified owner)

    I’ve ordered 2 times from Filti to make pleated masks for family and friends. This material is by far the best for pleated masks! The SPECS provide me with the satisfaction the masks provide added safety over cotton masks. The material sewn as a pleated mask weighs less than an ounce, so they are comfortable to wear. I feel confident being in public with the Filti material for my masks.

    I have been sewing cotton masks for friends and family since March 2020, and for at-risk groups since July. I live in California and when the smoke from forest fires hit our area the air was so bad you really couldn’t go outside without an N95, which no one could get. I sewed fitted filters for the mask pattern I use (which fits really well around the nose, cheeks and chin, and they filtered out all the smoke smell. They make my cottom masks much better than anything else I could find. Thank you for making this excellent filter material and for making it available in small batches for home use. You may very well have saved some lives!

    I purchased filti fabric back in February and I truly feel blessed to have found Filti when I did, knowing this year was gonna be tough and I cannot thank this company enough for what they’re offering to provide protection and safety to people. I even ran across online where a pediatrician was testing Filti fabric with homemade masks and it PASSED the in-hospital medical test! Thank you Filti! God bless you and your family Psalm 91! Anita

  17. Renee Cunningham

    Wow! It is so great to see that I am not the only one with a great experience with the filti filters! I bought green at the very beginning of all of this and made cotton fabric form fitting masks with the pocket for the filter. My family, me, my husband, my daughter, her daughter and her 1st grade daughter, along with my son, his wife, and two kids all have my masks, and I am realizing that none of us have gotten covid. We are all super safe, but we all wear the masks I made with these filters! We all feel so much better knowing that we have this extra protection. Thank you for such a great product!!

  18. Merrilee Suhr (verified owner)

    I’ve been using the filter material in the cloth masks I’ve made for several months. So grateful to have found this
    company when masks were in short supply. I buy the their NF95 respirators as well & they are breathable & fit with no gaps. Their prices are reasonable and customer service is great.
