Description
ComfortSeal Technology

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.



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 H2O | Tested 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 |

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.

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

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!!

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.

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.

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!

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!

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.
