Fit Testing with the Person's Own Assigned Respirator
Some respirators, especially older models, do not have fit test
adapters available. In that case, a permanently probed test respirator
is the only option.
Respirator Manufacturers' Technique
There are a growing number of respirator manufacturers who
provide sampling adapters that permit fit testing in one's own
respirator. Contact your distributor or call the manufacturer direct
and ask if such accessories are available.
TSI Fit Test Adapter Kits
TSI Sampling Adapters allow you to fit test using the respirator that
is actually used by that individual. Sampling Adapters for most
major brands of respirator are available. A complete list of fit test
adapters available from TSI and from respirator manufacturers is
posted on the TSI Web site

Homemade Adapters
A sampling adapter can be made by modifying a respirator
cartridge. This usually involves running a tube through the
cartridge and into the respirator. TSI recommends that you avoid
this option because it is so easy to do poorly. The most fundamental
mistake that is often made is to not extend the sampling tube
through the inhalation valve and into the breathing zone. This
combined with problems sealing around the outside of the tube
make this option unattractive.
Probes for Filtering-Facepiece (Disposable) Respirators
Disposable respirators can be fit tested by inserting a test probe through the
filter material. The optional TSI Model 8025-N95 Probe Kit includes
disposable probes and insertion tools. Order TSI Model 8025-N95R Probe
Refill Kit for additional probes (no tools).
