- How does a breathalyzer work?
- When a person consumes alcohol, the body immediately absorbs the alcohol in the mouth, the stomach, and the intestines. This alcohol is rapidly distributed into one's blood, which affects the central nervous system. The human liver acts as a filter for the bloodstream. Alcohol is removed from the body and passed through the alveoli in the lungs. With each breath, some alcohol is exhausted from the lungs and out of the body.
Breathalyzers are designed to test this exhausted alcohol for accurate results. By taking a "deep lung air" sample, a breathalyzer is able to draw a very accurate reading of your BrAC or Breath Alcohol Concentration.
Using a breathalyzer immediately after taking a drink can not only provide a high BrAC result, but also cause damage to the sensor. This residual alcohol in the mouth takes roughly 20-30 minutes to dissipate.

- How does an alcohol breathalyzer differ from other testing methodologies?
- There are generally three methods to test for one's alcohol concentration.
- Blood Alcohol Testing: The methodology used for blood alcohol testing is Gas Chromatography and is the most accurate forensic quality test in the industry today. However, drawing blood is an invasive and expensive procedure that most companies prefer to avoid.
- Breath Alcohol Testing: Breath alcohol testers range from disposable screening testers to the equipment that provides legally admissible results, including very expensive digital read-out breath alcohol monitors.
- Urine Alcohol Testing: Urine alcohol does not measure a true condition of the person. The results indicate the person's condition several hours before.
- Saliva Alcohol Testing: A correlation between blood alcohol concentration and saliva alcohol concentration is believed to exist, the technology and chemical reaction employed has not been proven to be accurate or reliable.
More information can be found in our article "Alcohol Testing Methodologies".
- Are breathalyzers accurate?
- Any hand held breathalyzer sold in the market should have the FDA (Food and Drug Administration) approval. Essentially, that means the FDA tested it and it does what it says it does in the product literature. Other approvals that confirm that the accuracy levels reported by the breathalyzer manufacturer are consistent with their findings include DOT (Department of Transportation), NHTSA (National Highway Traffic Safety Administrations) and U S Coast Guard.
Please be aware of imitation breathalyzers that are sold online. Many of these breathalyzers contain a cheap Chinese knock off sensor, that does little more than trigger an LED light to blink. It is our recommendation that you do not purchase a digital breathalyzer that costs less than $50 (or seems too good to be true) as these models provide novelty results.
- Can my results be used in court?
- Any result from a hand held unit is deemed as non-evidential. These devices are used as screening devices to determine if a more costly evidential test is required. Most devices used by law enforcement in the field are screening devices that provide the law enforcement officer enough reason to make an arrest under suspicion of a DUI/DWI. Results obtained by your personal breathalyzer will not be held in court, and should be strictly used to increase the awareness of your blood alcohol concentration.

- I don't feel fine, but my breathalyzer says I'm under the legal limit for a DUI
- Everyone reacts to alcohol differently. Even at low concentrations of alcohol, the affects of dizziness and diminished judgment can occur at .02% BAC. We recommend that you never get behind the wheel with any alcohol in your system, and to be tested by a friend who has not had any alcohol.
- Is it safe to test other people with the same breathalyzer?
- It is completely safe to test others with the same breathalyzer. To be sanitary it is recommended to use a new and unused mouthpiece when available. Also disposable breathalyzers are a one time use device, and cannot be used multiple times. The AlcAlert BT5500 is unique that it does not require the user's lips to come into contact with the device while testing, making it ideal for testing multiple people.
- Should I buy a used breathalyzer?
- The answer to this question is that you should never buy a used breathalyzer either through eBay or sites like craigslist. Always ask if the breathalyzer you are buying is brand new and never used. The reason is that breathalyzer sensors wear out from contamination or just over use. When buying a used breathalyzer, you will never know for sure how many tests have been performed on the breathalyzer. Even if it works when you get it, it may stop functioning after several tests.
- Is it spelled breathalyzer, breathalizer, or breathalyser?
- We find that a lot of people are using a different spelling for our devices. In the United States the correct spelling is breathalyzer. In Europe, or the United Kingdom, the proper spelling is breathalizer. We're not sure why people spell it breathalyser with an "s".
