ComfortSeal Technology

ComfortSeal Filter

Protect yourself with the ComfortSeal Filter. The foam gasket is made from closed-cell foam. It is both impermeable and non-porous which helps create a seal around the nose and mouth. This keeps inhaled and exhaled air passing through the high-efficiency, electrostatic filter. The filter material has been tested to 99.99975% Viral Filtration Efficiency and is used in ~90% of US Ventilators.

Upgrade Your Mask

Most masks do not fit securely against your face, which allows airborne contaminants to circumvent your mask and reach your airways.

The ComfortSeal Filter fits securely and comfortably against your face to block airborne particles that can sneak past your mask.

*Respirators only work as PPE when they are the right size and have been fit-tested to demonstrate an adequate seal around the face.

Masks are worn for both Source Control (SC) to reduce spewing out airborne particles and Personal Protective Equipment (PPE) to prevent the wearer from inhaling aerosolized viruses.

This analysis is a summary of available evidence showing the effectiveness of commonly used masks as SC or PPE.

Easy to Use

To start using the ComfortSeal Filter, just place it inside your mask. There’s no need for an adhesive or velcro! Your mask keeps the filter securely in place.

For an optimal seal, we recommend using masks with a conformable nose piece and adjustable straps.

Face Mask ComfortSeal Filter Fit Guide

Captures Particles While Increasing Breathability

Very
Breathable

The electrostatic filtration is low-resistance and allows for increased breathability.

Electrostatic
Filtration

By utilizing electrostatic action, the filter captures particles in the air which lowers the amount of contaminants you breathe.

Lightweight and Comfortable

The foam gasket creates a space between your mouth and mask, preventing your mask from being suctioned to your mouth.

How Long does the ComfortSeal Filter Last?

The electrostatic filter will not lose its filtration effectiveness unless it is heavily loaded with particles. This is unlikely to occur in normal use situations. 

The need to replace your filter is dependent upon the time and environment that you use it. We have found that, on average, the ComfortSeal Filter lasts about two weeks.

For someone who only goes out a couple of times a week in lower contact situations, the Filter can last up to a month.

If you are in close contact with people for many hours each day, but not in an infectious environment, we recommend changing Filters every two weeks.

When working daily in heavily polluted environments you may need to change filters more than once a week.

Filtration Effectiveness

All devices use the same high-efficiency, electrostatic filtration media. The filter media has been tested by independent labs to meet the following criteria:

NaCl Penetration at 32 LPM< 0.10%Tested in accordance to TSI8130 NaCl 0.1 micron particle size
NaCl Efficiency at 32 LPM> 99.90%Tested in accordance to TSI8130 NaCl 0.1 micron particle size
Pressure Drop at 32 LPM< 2.3 mm H2OTested in accordance to TSI8130 NaCl 0.1 micron particle size
Air Permeability> 85 CFM Tested in accordance to ASTM Spec ASTM D373
Bacterial Filteration Efficiency> 99.99990%Tested in accordance to Spec MIL-M-36954C By Nelson Labs
Viral Filtration Efficiency> 99.99975%Tested in accordance to Spec MIL-M-36954C by Nelson Labs

9 reviews for ComfortSeal Filter for Surgical and Cloth Masks (Pack of 3)

  1. Laurie Sauerbry

    These are wonderful filters! My husband and I wear them every time we pick up groceries, attend outdoor gatherings or go to appointments. They close the gaps and provide an effective filter to make us feel far safer whether we are indoors or outdoors.

  2. Vicki Colburn (verified owner)

    Very comfortable and easy to breath through. They work great on airplane. I will be ordering more.

  3. Marianne and John Siefer (verified owner)

    I ordered two ComfortSeal Filter for Surgical and Cloth Masks along with some spare filters for both my husband and myself. They are extremely comfortable and we both love that we are wearing a mask, with your filter inserted, that now truly makes us feel safe from catching this virus!! Thank you so much for making this amazing filter!!!! I am recommending it to all my friends!!

  4. Kim Jackson (verified owner)

    These filters improve both my comfort while wearing a mask and my safety in public. The added layer of filter ensures that a disposable mask is more effective, it is easy to wear, And actually more comfortable than the mask alone.

  5. Cynthia Lindeman (verified owner)

    I like the comfortzeal under a cloth mask. Your mask can be lighter weight and the seal keeps the fabric off of your face. Easier to breathe. The trim to fit fabric works real well in the paper masks.

  6. Jane May (verified owner)

    I ordered the ComfortSeal filters in two sizes thinking I would wear a medium and my husband the large. In trying them on with our favorite outer masks we discovered that different sizes fit better with different masks. Now I claim a large ComfortSeal filter in my collection and my husband claims a medium in his. I would recommend ordering more than one size to accommodate all the different styles of outer masks that we all now seem to have. It’s nice to feel safe and have options!

  7. Judy Klopp

    Great filters! We have both the Trim-to-Fit Filter and the ComfortSeal Filter. I work in a school and my husband works out in the community. We have a mask for each day of the week, we use a different filter for each mask. We wash the masks at the end of the week and reuse the filter until it is time to replace it. The filters provide us that added protection. They are comfortable to wear, we highly recommend them!

  8. sebold.rachael (verified owner)

    I definitely recommend these filters! Sending my kids back to school feels scary, but it is comforting to know that they have these filters to protect them. On top of providing a higher level of safety, the filters are easy and convenient to use.

  9. Molly Sauerbry (verified owner)

    Great product. I feel a lot safer wearing it!
