N95 fit testing

If you or your employees will be using our fit testing services all “fit test subjects are required to read and agree to the OSHA guidance under 1910.134.

Please Note:

Northwest Response has been advised by Washington State Department of Labor & Industries, with additional guidance from the United States Department of Labor, CDC/ NIOSH of an acceptable protocol to expedite N95 Fit Testing.

The “Just In Time” Method It is now an option. Just in time allows us to use Qualitative Testing Protocols (QLFT), thus reducing testing time to test up to 16 test subjects per hour with a single tech. This lowers cost using non destructive methods, and saves the N95 respirator for future use.

Minimum Site Fee: $450.00 covers the first 20 test subjects, each additional fit test is $20.00. (see contact form below to schedule)

Update: March 18th 0700hrs:

NOTE: Per OSHA CFR 1910.134(g)(1) Facepiece seal protection:

We do not fit test persons with facial hair that compromises the seal of the respirator. All fit test subjects must be clean shaven where the respirator meets the skin. No beards, no stubble. Sorry…No exceptions.

We are working around the clock to cover as many shifts as possible.

Please use contact form below to schedule.

We do not supply N95’s. Each facility must supply N95’s for fit testing and use. Additionally with N95 respirators being in very short supply we are encouraging our clients to adopt Qualitative (QLFT) non-destructive fit testing methods.

UPDATE: March 13th 1600hrs:


As you might expect we are very busy fielding calls, and providing N95 Fit Testing services to Healthcare professionals who have lots of questions. We have compiled a list of FAQ’s that we hope will help in case we aren’t available to return your call or email right away.

With the new Department of Labor Regulations can we skip the Fit Test until the CV-19 has passed?

Simple answer is NO! You still need to get your personnel fit tested. The Dept.,of Labor is giving you time to get the test done. You may not be fined on the first L&I visit, but you will be warned to seek services, to comply with CFR 1910.134, but its not a pass on fit testing all together. If you have resources to get N95 Fit Testing done, then you must. It’s not a pass.

How soon can you come to our facility and test?

Right now we are booked about two (2) days in advance.

What is the fee?

Option One:
(QNFT) Quantitative Fit Testing:
Recommended for smaller groups of fit test subjects of up to 25.

Minimum site visit fee of $700.00. This fee covers the first ten (10) fit tests. We have lowered the fee for each additional fit test to $50 per test (down from $60 per additional fit test.)

Option Two:
(QLFT) Qualitative Fit Testing:
Recommended for large groups of fit test subjects > 25 per day.

Minimum site visit fee of $450.00. This fee covers the first twenty (20) fit tests. We have lowered the fee for each additional fit test to $20.00 per test (down from $40 per additional fit test.)

Site visits are limited to ten (10) hours per day. Additional days are billed at the normal minimum site visit fee.

What test do we need?

Ideally: For N95’s you need Quantitive Fit Testing. This requires a machine that we use called a “PortaCount “. The PortaCount works by measuring the concentration of microscopic dust particles in the ambient air and then measuring the concentration of those dust particles that leak into the respirator. The ratio of these two concentrations is called the fit factor. The N-95 respirator stops essentially all the particles so anything that gets into the mask must have come through the face seal.

During COVID-19 you can use the QLFT “Qualitative” Testing Methods”

How many people can you test in an hour?

That depends on what test we are conducting.

For Quantitive Fit Testing: (QNFT)
1- PortaCount can test up to six (6) persons per hour
2- PortaCount’s can test up to twelve (12) persons per hour
3- PortaCount’s can test up to eighteen (18) persons per hour
Requires second technician (add $360.00 per day)
4- PortaCount’s can test up to twenty four (24) persons per hour
Requires second technician (add $360.00 per day)

For Qualitative Fit Testing: (QLFT)
One Tech can test 16 subjects per hour.
Two Tech’s can test 32 subjects per hour.

How long does it take to do a fit test?

We have an excelerated OSHA compliant protocol that can reduce test time to about ten (10) minutes per test per PortaCount on QNFT and about Five (5) minutes per test in groups of 4 with (QLFT).

Do we need medical evaluations?

You should get medical evaluations on all employees who wear a respirator. Quick and easy evals can be completed at the 3M Resp Exam Website

How many N95 respirators do I need?

One for each person being tested. During QNFT testing each N95 used in testing is destroyed during the testing procedure.

With QLFT the respirator is saved for future use.

Do test subjects need to be clean shaven?

In a word…. YES!

Is there any training that needs to be presented?

We will give a “basic” overview of the limitations of the N95, proper use, care, donning & doffing. However, this in not a replacement for full Respiratory Protection Training, however should suffice during this crisis.

What are the payment terms?

In some rare cases we may ask for a 20% deposit with the balance due net fifteen (15) days. Otherwise you will be invoiced and all fees are net 15.

Do we get a card?

Yes, you will receive a copy of the bench test reports, and a wallet card “Certificate of Quantitive (or Qualitative) Respirator Fit Testing”

Are all N95’s alike?

Yes and No! All N95 respirators should be certified by the National Institute for Occupational Safety and Health – NIOSH. However, styling is different from brand to brand.

When we test your personnel, the mask tested in (make & model) is the one that needs to be used. You can’t switch to another brand or model number.

One Size does not Fit All!

Contrary to popular belief its not one-size fits all. Fitting a person with a very broad face, broad nasal bridge, pronounced nose or chin, receding chin, are all very challenging and may require the facility to have more than one brand, or model number on hand to protect all of their personal. We have spent up to 40 minutes with one Healthcare Professional to find the right respirator to achieve a fit.

We are currently Fit Testing N95 respirators throughout Washington State. This week we are Fit Testing in Seattle, Tacoma, Lakewood, Bellevue, Redmond and Olympia. Fit Testing appointments may include 2nd and 3rd shifts. When considering scheduling a respirator fit test be mindful that QNFT (Quantitative) testing may be 5-7 days out. Please consider QLFT (Quantitive) for prompt fit testing of your staff for N95 respirators.

1910.134(g)(1) Facepiece seal protection.1910.134(g)(1)(i)The employer shall not permit respirators with tight-fitting facepieces to be worn by employees who have:1910.134(g)(1)(i)(A) Facial hair that comes between the sealing surface of the facepiece and the face or that interferes with valve function; or1910.134(g)(1)(i)(B) Any condition that interferes with the face-to-facepiece seal or valve function.
