The Quantifit Respirator Fit Tester is the industry breakthrough in portable mask-fit technology which uses Controlled Negative Pressure (CNP) instead of traditional aerosol particle counting.

Virtually maintenance-free with no wicks, no candles, no incense or any other consumables, Quantifit is the simplest and most cost-effective fit testing system available in the UK and Ireland. (Read More)


Already widely-used in many industries around the world where fit-testing is applicable, including emergency responders, the easy-to-use technology means it can test after a one-minute warm up in virtually any environment as long as air is present and there is a power supply, a unique benefit over its competitors.

Below is a typical customer testimonial explaining why Quantifit comes so highly recommended:

“As we have migrated over to the Quantifit Fit Test system we are finding that we are able to perform our fit tests in about half the time, or less, compared to what it was taking us before. Since we perform about 5,000 fit tests annually, we have seen a reduction in overtime costs and real-time savings for staff as well. Both myself and my staff spent a lot of time researching the available products for fit testing and chose to the OHD Quantifit. This decision was made based on several factors including immediate cost, long-term operating costs, customer service, ease of use, ease of training and the time involved in each actual test. The Quantifit was the clear winner for our needs.” – Bill Merritt, Executive Director, Environmental Compliance, Safety and Emergency Operations, Maryland.  
Traditional aerosol fit-testing products count particles to measure gas, vapour and particulate. If there are not enough particles in the air to test, the user has to light candles or incense or generate salt fog to create the particles needed to complete the test.

Exclusively available from Shawcity in the UK, Quantifit is revolutionary as it doesn’t count particles but uses controlled negative pressure with air as the challenge agent, quickly and safely demonstrating that if air can get into the respirator then gases, vapours and particles could too.

So how does Quantifit work? During a fit test the subject holds their breath for ten seconds while the Quantifit establishes and maintains a slight vacuum, or controlled negative pressure, inside the mask. Since the respirator inlets are sealed, all sources of leakage into the mask are through the face-to-facepiece seal or due to integrity issues. The volume of air drawn out of the mask by the Quantifit during this short period of time is equal to the leak rate into the mask through the face-to-facepiece seal. The fit test also covers redonning, where the subject takes off and puts back on the mask to test the seal and fit in circumstances similar to real-life use.

A simple one-minute daily calibration ensures it is working within a strict tolerance, a huge time-saving benefit. The system is so simple to operate that many users self-test once trained, another key advantage over competitive products. Quantifit is a portable, standalone unit weighing less than 3.5kg which stores up to 500 fit tests without power for two years.

Quantifit’s FitTrack Gold software allows users to print wallet-sized fit test cards on any standard, Windows-based printer, with a dedicated card printer and laminator available as an option, whereas the market leading aerosol product only operates with a special printer, adding up to 30% to the purchase price if this function is required. Additionally, with quicker fit test times, no consumables and no internal optics being contaminated, Quantifit offers tangible cost of ownership and time efficiency savings over its competitors.
