Frequently Asked Questions

The DC1100 Air Quality Monitor has been engineered to be simple to use and simple to read. However, below are some frequently asked questions that will make understanding and using our monitor even easier.

What do the two numbers mean?

These numbers represent the number of small(fine) and large(coarse) particles detected. They are a running average of the particles counted in the past 10 seconds. The number on the left is the small particle count and the number on the right is the large particle count. The numbers are approximately what a 12 year old would inhale in a single breath. The small particles can include fine dust, bacteria, mold, smoke, etc. (from approximately 1um and up). The large particles can include coarse dust, pollen, dust mite casings, etc. (from approximately 5um and up).

What does the graph mean?

The dynamic bar graph allows the user see an instant response to changing air quality. The graph is a simple and intuitive way to see large and small particles being counted. When the dynamic bar graph is short and does not extend out to the right, it means that small particles are being counted. When the dynamic bar graph is extended almost to the end, or completely to the end, it means that large particles are being counted. The DC1100 can count much faster than the bar graph can update so the graph really represents a summary of particles counted in the last 1/20th of a second.

Will one DC1100 Air Quality Monitor test all the air in my home at the same time?

No. Our monitor is light-weight and can easily be transferred to any room in your home. Let's say you have your the DC1100 in the kitchen during the day, but later that night you want to monitor the particle counts in the family room where everyone is. You simply unplug the monitor in one room and plug it in another. Our unit is reasonably priced making it affordable to purchase more than one unit.

Will the DC1100 Air Quality Monitor work in an office setting?

Yes. DC1100 Air Quality Monitor will work in your office. It has been designed to monitor office settings as well. Simply follow the same instructions for home use.

How do I read the history?

You access the history modes by using the mode and select buttons on the front of the monitor. There are three different histories provided, minute, hour and day. Minute history will give you an averaged particle count for each minute at a time, up to 60 minutes in the past. Hour history will give you an averaged particle count for each hour at a time, up to 24 hours in the past. Day history will give you an averaged particle count for each day at a time, up to 30 days in the past.

How does monitor mode work?

In monitor mode the unit sleeps and only comes on for 60 seconds every hour. A sampling of the air is taken and a count of large and small particles is saved to history. This mode is for people who do not want the unit to run continuously but would like to be able to look back in history to see what the counts have been over time.

Is there any maintenance required for my DC1100 Air Quality Monitor?

Only occasional cleaning, but it's so simple. All you do is use dust remover air (you can get this at any electronics store), spray it into the top vents on the back of the unit for about 10 seconds. That's all! This maintenance keeps the air moving freely so that the Air Quality Monitor will work as efficiently and effectively as possible.

Is there an email address that I can contact Dylos Corporation if I have any additional questions?
