Frequently Asked Questions

Masks

NF95 stands for NanoFiber 95. The 95 is indicative of our target specification of 95% efficiency at 0.3 microns. It does not signify certification of any kind.

The NF95 is intended to be a disposable mask and we do not recommend washing it.

We recommend wearing the NF95 mask for 12 hours before replacement.
We do not offer children sizes at this time, but we are looking into possibly offering them in the future.
We have discontinued the surgical masks in order to focus production on the NF95, as it is a superior mask.

Materials

The material is an 80gsm, three-layer design consisting of a polyester spun lace outer, tight network of nanofiber created using our FDA certified raw polymer, and polypropylene spun bond scrim to support the nanofiber.
Manufacturing specs are targeted at 95% efficient at 0.3 microns (per lab test 6.2 dp 95.3% efficient). The airflow spec for this material is a maximum 60 pascals dp at 5.33cm/sec face velocity at 32 liters per minute.
It has been recognized by “Advanced Filtration Manufacturers Association (AFMA)” that advanced materials used in face mask filtration should not be washed due to the material damage and decrease in filtration quality.
We do not offer children sizes at this time, but we are looking into possibly offering them in the future.
In light of the pandemic, the CDC understands Filtering Facepiece Respirators (FFR) decontamination and reuse may be needed during these times of shortage to ensure continued availability. If you choose to reuse the material, we recommend following CDC sanitization guidelines while continuing to handle your material with caution: Decontamination and Reuse of Filtering Facepiece Respirators.
Just one! Adding multiple layers will slightly increase the overall efficiency but will also greatly decrease breathability and air permeability through the material.
There is no latex in any of our materials or finished products.

Filters

Yes! Our filters have a MERV Rating up to 16 and helps filter bacteria along with dust, lint, pollen, mold, pet dander, smoke, fumes, odors, viruses, and PM 2.5.
Unfortunately, we are not able to offer custom sizing options at this time.
Simply use warm water and soap with a soft sponge or your hand. Alternatively, our washable cleaning solution has been formulated for our washable filters and helps retain a high filter efficiency with every wash.
Typically, every 2 to 3 months you will want to wash your filter. In some cases, it may be best to check every month, especially in regions with poorer air quality.

Fulfillment & Shipping

We are currently only able to ship to the United States and Canada. Orders to Alaska, Hawaii and Canada have an additional $40 shipping charge. For large custom orders we will ship internationally if MOQ’s are met.

Shipping is free for all face mask products as well as any 4 pack of filters. Orders over $100 also ship free. Free shipping is limited to the continental US. Orders to Alaska, Hawaii and Canada have an additional $40 shipping charge. Shipping costs depend on order weight as well as shipping address location and can be estimated during the checkout process.

You will receive an email with live tracking information for your order once scanned into transit by the shipping carrier.
Do to an increase in demand and order volume, please allow 5 – 7 days for fulfillment time and an additional 5 – 7 days for carrier delivery.

Misc

Nanofiber technology creates a very fine, continuous, resilient fiber, that mechanically filters pollutants.
There is a critical distinction to make here – nanofibers are NOT nanoparticles. While very thin in diameter nanofibers are continuous in length and form a bonded network. This network is technically a nanofiber membrane that feels like a very thin elastomeric sheet.

Filtration efficiency in terms of bacteria filtration efficiency and particle filtration efficiency testing regarding the face mask media has been conducted by Nelson Laboratories. The results can be found under the material product page as well as here:
