Liners for Face Mask (PM2.5 Carbon Fiber Fabric Filters) (10/20/30 Packs)

** This listing is FOR FILTERS ONLY. If you need face masks, please see my other listings :) Thank you.

- When you pay for this listing, you will receive 10, 20, or 30 pieces of PM2.5 Filters.

- The price also includes shipping to U.S. Domestic (including Hawaii and Alaska) WITH Tracking information by US Postal Service. *** (added 2020-07/30) Please kindly note that it seems US Postal service is running slow at this time due to the current situation and it might take longer for you to receive the order. I always try to ship orders in 0-1 day, but USPS.COM might not update the tracking information after few days I drop off your package at a post office.



- 5 layers 2.5PM filtering system;

1) Carbon Fiber Fabric
2) Non-woven Fabric
3) Melt-Blow Fabric
4) Non-Woven Fabric
5) Melt-Blown Fabric


- Filter Size: about 4.7" x 3.15" (12cm x 8cm)


- Easy to insert or replace the original filter by putting in the PM2.5 filter pocket in fabric mask. Filter insert can not be cleaned and should be replaced every couple of days, or when filter gets dirty, please replace it sooner.




- Keep away from PM2.5, dust, haze, allergies, ash, pollen, gardening, vehicle exhaust, woodwork, airborne contaminants, etc..



- Ready to ship from LA area, CA USA. I usually ship in 0-1 business day. I try to ship on Saturday too if I can, as USPS works on Saturdays and people might need these asap. Thank you :)



- Coupon is available if you are my previous face mask customers. Please find coupon code in your order package :)
