Frequently Asked Questions (FAQS)

Are personal breathalyzers accurate?

With a good quality alcohol tester, you should get reliable results when you use it correctly. However, don’t expect any model out there to provide the exact results that you will get when using law enforcement equipment. However, some deliver readings that are very close to the actual values.

What the most accurate breathalyzer?

Although we have many fake breathalyzers out there, we still have a few models that give values that are much closer to the actual blood alcohol content. Examples of these testers are those on this list.

Why breathalyzers are not accurate?

As aforementioned, breathalyzers are not very accurate. Well, the major reason is that they are not made to measure the actual BAC. Instead, these alcohol testers are made to rely on an estimate.

How many hours does it take to get sober?

The amount it takes your BAC to hit 0.00% will depend on how much you drink and the alcohol content of the drink. The more you drink, the more hours it will take for you to become sober. Also, when the alcohol content is very high in the drink, it will take more time to become ‘normal’.

Are blood tests more accurate than breathalyzers?

Yes. Because they check on alcohol content in blood and not in the breath. This makes them more accurate than the breathalyzers since they don’t rely on estimation but actual measurement.


With a good breathalyzer, it’s easy to tell whether you will fail or pass the police alcohol checkers. Unfortunately, with tons of options already in the market, getting a reliable model remains a major puzzle to many.

That’s why we have put together the market’s most accurate options on this list. Just go through the review to identify the one that seems to impress you the most.
