Best Indoor Air Quality Meters Buying Guide
Before choosing the best indoor air quality meter you should consider following options:
1. Accuracy: Look for a meter that offers accuracy that is either ISO or NIST traceable. Accuracy is an important factor when purchasing an air quality meter because it helps ensure that the readings you get are as accurate as possible.
Accuracy also ensures that it is easy to compare readings for different locations. If you have a home with two air vents, you can use a meter to compare the levels of mold in each room. If the levels are the same, then you can eliminate the vents from your remodeling plans.
2. Speed: The speed at which an air quality meter measures and displays results is also important. Faster meters allow you to take readings of the air in your home much more frequently.
This helps you track changes in the air quality, which can alert you to any potential problems. For example, if you begin to notice a significant buildup of mold in your home, you can take action before the problem becomes severe.
3. Cost: Air quality meters come in a wide range of prices. Some of the cheaper models are limited in their functionality, but others offer a full set of features at a reasonable price.
4. Portability: Air quality meters come in both handheld and non-portable options. Handheld meters are great for measuring the air quality in your home or business, but they don’t offer the same level of accuracy that non-portable units do.
