Frequently Asked Questions

Masks

What does NF95 mean?

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.

Are the NF95 masks washable?

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

Are the NF95 masks reusable?

We recommend wearing the NF95 mask for 12 hours before replacement.

Do you offer children sizes for the NF95?

We do not offer children sizes at this time, but we are looking into possibly offering them in the future.

Why do you no longer sell the surgical masks?

We have discontinued the surgical masks in order to focus production on the NF95, as it is a superior mask.

Materials

How is the facemask material designed?

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.

What are the manufacturing specs?

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.

Is the facemask material washable?

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.

Do you offer children sizes for the NF95?

We do not offer children sizes at this time, but we are looking into possibly offering them in the future.

Is the facemask material reusable?

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.

How many layers of Filti material do I need to use in my mask?

Just one! Adding multiple layers will slightly increase the overall efficiency but will also greatly decrease breathability and air permeability through the material.

Does your material contain latex?

There is no latex in any of our materials or finished products.

Filters

Does Filti help filter out bacteria?

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.

Do you offer custom sizing options for HVAC filters?

Unfortunately, we are not able to offer custom sizing options at this time.

How do I wash my washable filter?

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.

How often should I wash my washable filter?

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

Do you offer international 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.

How much does shipping cost?

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.

How do I track my order?

You will receive an email with live tracking information for your order once scanned into transit by the shipping carrier.

How long will my order take to fulfill and ship?

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

What is Nanofiber Technology?

Nanofiber technology creates a very fine, continuous, resilient fiber, that mechanically filters pollutants.

Is nanofiber safe to breathe through?

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.

Is there any third party testing data for filtration efficiency?

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:
