Just what I need to for my health with COPD
I ordered the Airthings View Plus Smart Indoor Air Quality Monitor because of where I live and the fact that I have Chronic Obstructive Pulmonary Disease (COPD).
Our Home is on the “Front Range” (just east) of the Rockies in Colorado. It can be quite dry here because of the 7,500 feet elevation above mean sea level. In last 10 years we have had three major wildfires within 20 miles and this year we’ve suffered the smoke effects of fires in six states west of us. We’ve invested in Air Purifiers, humidifiers and recently had air conditioning installed to mitigate the effects of smoke. We needed a way to measure the air quality in our house and some idea of what to do if the quality is bad. The View Plus meets our needs brilliantly for measuring harmful contaminants, affecting my COPD: PM2.5, CO2, and VOC. As a bonus we also get Radon, Humidity, Temperature and Barometric Pressure.
The out-of-box experience was very easy, although I had to go looking for a plug adapter as there was not one provided. At the View Plus price point it seems cheesy to not include a plug and the hassle of cannibalizing plugs from other devices is annoying.
Setup was easy once the app was downloaded. It takes a while to get preliminary readings, so be patient. The app provides easy options for viewing the readings from the monitor and it allows you to set tailored alerts for when a readings may require action. You have the option to see simple green, yellow and red ratings for the last 48 hours. You can view your statistics by clicking on the Web Dashboard and then tailor your view’s time frame. Hovering your mouse along the graph’s lines for each element will give you the specific date and readings. In the dashboard view under each element’s reading of the last 48 hours you can click on a tutorial for the element. The tutorials are detailed but easily understood (if not easily retained ;-) The very best part of the app are the actions it recommends when the readings for an element are bad.
Airthings View Plus gives us the tools we need to leverage our investments in Air Purifiers, Humidifiers and Air Conditioning to improve our indoor air quality and ultimately our health. We have a two-story house and while we could move a single monitor up and down to both floors, we are really glad we got two systems to track the air on both levels consistently.
Airthings, Brand, “View Plus” Battery Operated, Complete Smart Indoor Air Quality Monitor with PM2.5, CO2 and Radon monitoring are becoming more and more important things to be aware of just as temperature, humidity and atmospheric pressure. Airthings, View Plus does it all for a home or office and data is stored to the cloud and instantly available on a smart phone or PC. The View Plus does require a smart phone for setup. However, once setup, it can be accessed by PC. Initial setup proved to be a bit difficult for me as either the View Plus or my Samsung A11 phone refused to communicate. Several resets of the View Plus and reboots of the phone eventually resulted in a Bluetooth connection. I felt the setup guide to be woefully inadequate. The View Plus takes seven days to calibrate to its location and once the nation location is set at Airthings server, it cannot be changed. The Airthings server does provide an AQI based on all the air quality data in the home or business where installed. Since I am in California, and we have had several AQI days traveling and at home in the 500’s, air quality has become an even greater concern for us. And while we have several fires burning a 100-miles to the east, my View Plus has detected higher levels of PM 2.5 on days overhead smoke was causing the sun to cast an orange glow to the ground below. The batteries are said to last two years. And I prefer not to leave alkaline batteries in any longer than that due to leakage such that battery operation makes more sense to me than using a USB AC adapter.
Indoor Air Quality Monitor and Dashboard App, but limited iOT integration
GENERAL COMMENTS & OPERATION:
This sensor is over an inch thick so it sticks out from the wall even farther than my Honeywell Thermostats. However, I suspect that the thick profile contributes to its silent operation.
The E-ink Screen shows the results from two sensors. You can pick which two results to display from a list in the app.
There also may be a row of black dots across the top of the screen. I believe that each black dot represents a reading that is not in the “green” zone. However, the row of dots always has equal spacing. It is not a row of 7 dots with gaps representing reading outside the green zone (which might have been more useful).
If you wave in front of the screen, a colored light indicates the air quality. My display then shows me PM25 followed by Humidity;I suspect that is because those 2 readings are always in the yellow zone or worse in my home. For example, when VOC is high, I think it would show me the current VOC reading as well.
It is telling me the particulate in my air is in the caution zone pretty much all the time which doesn’t make me feel very good. If it told me everything was fine most of the time, I would probably love this thing, but right now, I don’t. How do I act on this information? I am not actually willing to waste energy turning on filters, etc at this time of year. Instead, I leave my windows open whenever at least one person is at home. The particulate is high with my windows and patio doors open even when the Breezometer site indicates green AQI in my area. I do not live in a big city, I live in a small town about 7 miles from the Pacific Ocean. When it is cooler and my windows are closed more often (in January and February), I will probably use an air filter if the particulate is high indoors.
The packaging is quite elegant. The box design is admirable and appropriate for a high-end, high tech, product.
This kit includes a strong, 6’ long USB-A to C cable, but I decided to use the 6 AA batteries (also provided). With the cable readings would be reported to the cloud every 2.5 minutes, but when on batteries, the user chooses between reporting once every 10 minutes and once every hour to conserve power.
The instructions suggest mounting it at least 3 feet away from any windows.
The sensor snaps on or off its mounting plate making it easy to mount on a wall or just sit on a desk. The plate has two holes for countersunk screws. I think either M4 or #8 would be a good size, but I used the command strips provided because I want to be able to move it easily if I find a better place to mount it.
I have used command strips before. If you have not, be sure to go online to get instructions. Three small picture hanging strips are included with the sensor.
Each sensor can only have one log-in associated with it. You will need to set up one account for the whole family to use.
The E-ink Screen displays the results from just two of its sensors. You can pick which two from a list in the app: Radon / PM / Temperature / Humidity / VOCs / CO2 / Air pressure / Outdoor Air Temperature with an icon for the current weather conditions
It takes a week to “calibrate” some of the measurements, but I don’t know what it is using as calibration standards.
Airthings suggested Breezometer to get information about outdoor air quality. I had not seen Breezometer before, but it is a nice web-site with maps and notifications you can set up.
My Personal Weather Station is connected to WeatherUnderground. I like to share the data with my neighbors. Before ordering this station, I used both AirNow.com and PurpleAir.com when I was curious about the air quality in my area. However, Airthings is not designed for public reporting of data. Because it is for use indoors, your data is for that room in your house so it is not shared with the public. Your log-in credentials are required to access the data in the app or on the web. It does have an API so if you have some basic programming skills, you can probably put together a web-site.
PARTICULATE: I don’t have any other particulate sensors in my house so I have no way to check its accuracy. I have read that some laser particulate sensors can become inaccurate when the ambient temperature is near the dew point because moisture in the air can look like particulate. Therefore, I went to the Contact Us page of the Airthings web-site and asked about the effect of dew point on particulate sensor accuracy.. I asked on a Friday afternoon, but I didn’t have to wait long for an answer. Just 4 hours later I received an email from @airthings.intercom-mail.com stating: “Generally, we don't recommend our devices being exposed to high humidity and the threshold for it is at 80% as too much exposure to it can cause the sensors to malfunction.” This sensor is for use indoors; I think that dew point is more of a problem for outdoor sensors.
VOLATILE ORGANIC COMPOUNDS: The VOC readings are believable. They went sky high when I was wiping this with Kirkland Wipes and Alcohol before using the Command Strips to hang the sensor on the wall. A couple days later, as another test, I cut a corner of another Kirkland wipe and wiped down the wall. The VOC reading went into the red zone again. However, most of the time this reading is in the green zone. I notice that it does step up a little when all the windows and doors are closed. I guess this isn’t surprising because my house was built just 2 years ago and a lot of the furnishings are less than a year old and probably still outgassing.
TEMPERATURE, HUMIDITY & PRESSURE: These readings on the dashboard are believable. As a test, I set this meter next to my indoor weather station for 10 hours. I will attach charts for the Airthings and my personal Weather Station (an Ecowitt GW1000) as a photo. A direct comparison would be easier to read, but when I downloaded the data from both sites, something went wrong with the AirThings CSV file. The downloaded data shows the Airthings Temperature rising when the Airthings Dashboard shows it falling. My Personal Weathers Station also reported it as falling. I don’t want to spend hours figuring out what went wrong, so I included snapshots from their websites for comparison.
You can integrate data from your Airthings ViewPlus with IFTTT, Google assistant and Alexa.
If this is important for your application, I recommend visiting each assistant to see what data it can use. For example, in my experience Alexa can tell you which of your rooms have Airthings Sensors and what the Radon Levels are in those rooms. She does seem to be able to report on any of the other readings.
The outside Air temperature and weather conditions that can be shown on the ViewPlus display are taken from the Breezometer web-site. There is no way to link it to your own personal weather station.
There is an API that users with some programming experience may be able to use to add it to their own web-site. ActionTiles or other smart home hub display.
It is interesting that the downloaded Airthings text file uses semicolons as separators even though it is called a comma-separated-value file (.CSV). It was interesting to see different periods for the different readings. The particulate readings for PM1 and PM2.5 are reported the most often. They are on two rows, then skipped, then on two rows again. Temperature, Humidity and CO2 readings are recorded together on every 3rd row in the data, the row that doesn’t have any PM readings in it. Pressure and VOC are included with every 4th PM reading. The radon reading breaks up this pattern. It gets a row all to itself every 20 minutes or so. Also, the reading frequency may be different if you plug in the cable; I am using the batteries, but not the battery saver. I plan to turn on the battery saver after the 7-day calibration period has completed.
I received an email from Home Depot alerting me that a Home Depot "Seeds" campaign was available so, I went to the "Seeds" dashboard page to see what my next available project for review was. As I started going through the items I'm constantly thinking about commercials or what was innovative technology that had been advertised and now available. One of the items had been a radon test kit that senses the presence of radon gas that seeps through the basement floor and tests the kit for a fee. What the test tells you if radon gas is currently present, next month another test, another fee. Radon is always a potential hazard because the changes in the earth under you house, is constantly changing. My wife passed away in December and a some of the symptoms that she was having, I've developed as well. We've lived here for forty-four years and the only thing that is consistent is the time we've spent living here. The AIrthings View Plus constantly measures all the Radon Gas levels, 2.5 particulate matter, PPM of CO2, humidity level, air temperature, VOC levels, air pressure, and 1.0 particulate matter, measurement. Looking at the results of my limited investigation, I already know I will have to install a Radon Mitigation system in my home. Time will tell but I know it answered my questions about my air quality. A worthwhile investment.
Indoor air quality has been getting lots of attention lately, and for good reason. Poor air quality can have a significant impact on a variety of respiratory and other ailments. Here in the Pacific Northwest, smoke from wildfires is of particular concern. Thus, when I saw this Airthings View Plus Battery Operated Smart Indoor Air Quality Monitor, I knew I had to give it a try. The product is nicely packaged and very easy to install and set up. The Airthings app syncs seamlessly with the monitor and the display is well-designed. The unit can be positioned on a surface such as a countertop, or wall-hung. Checking air quality is as easy as opening the app, or at the monitor by waving your hand in front of the display. Real time readings of PM2.5 (particulates), radon, humidity, temperature, and barometric pressure are available immediately after set up. The CO2 and VOC sensors require 7 days to calibrate, and afterwards are reported with accuracy. I'm very impressed by this monitor, and highly recommend it!
SIGNIFICANT UPGRADES; WIFI ISSUE; NO DIRECT CALIBRATION FOR ACCURACY
This version of the Airthings View Plus Battery Operated Complete Smart Indoor Air Quality Monitor with PM2.5, CO2 and Radon has three upgrades from the previous version. It now supports WiFi. It has a rechargeable battery. And it has a display for information on the unit. The display always shows the value for radon and PM2.5. If you wave your hand over the unit (sometimes it may take multiple waves), it will either say all is good or show you the values and names for the readings that are not in the green zone. With the WiFi-enabled app, you can see all of the current readings and charts for previous data. The WiFi is a great addition and the app is easy to use. The app also displays the current charge for the battery. Thus far, it has used 20% of the battery in seven days. One issue that we have with the WiFi is that the air monitor is in the living room which is where we stream content to our TV. Thus far, when we stream, the air monitor degrades the transmission and we have interruptions in the video. Maybe that will improve or we will need to move the monitor elsewhere or force a stop on the app when we want to stream to the TV.
One question mark of an otherwise useful monitor of air quality is that there is no direct, external calibration for the accuracy of the readings. In 2020, the Canadian National Radon Proficiency Program tested the previous version of this air quality monitor for its radon accuracy. It determined that the measurement error was >20 % and <=30 %. The Airthings View Plus states an accuracy of 10% when compared with the readings of the AlphaGuard radon detector. But then one needs to know the accuracy of the AlphaGuard detector. It is quite possible that the accuracy of this version is better than the previous version but we do know without a direct calibration by an independent laboratory. Even if the radon detection accuracy has not improved, it still may be a worthwhile air monitor, it is just that the user should know the actual accuracy. The monitor is assembled in Tunisia.
This device is very useful for us. For several years now we have dealt with forest fire smoke in the summer and fall. Our house is older and does not have central AC; so, there’s a tradeoff between opening the windows for ventilation/cooling and possibly getting bad air into the house.
Online services now give us very good data on outside air quality where we live but we’ve never been able to compare what’s going on outside our house with what is happening inside. That is, until setting up this AirThings monitor.
Now it is easy for to make a decision on whether it is better to keep the windows closed or to open them.
We’ve also already learned some other things… We were surprised to see the device register higher levels of indoor contaminants just after cooking a complicated meal (exhaust fan on but with lots of things on the stovetop) and then see that the fan function on the furnace, with a good quality air filter installed, quickly removed those contaminants. Both were useful to learn and I’m now looking at getting a more effective exhaust fan.
The app works well and provides more info than the device display (see photos). The app was also easy to install and configure to our home network. It will also alert you when there is a reading that is abnormally high. The latter function is how we realized that all of the cooking was causing a problem.
We definitely recommend the product.
There are a few things would make for great improvements in future versions: 1. When there is only one device the app should automatically open to show that device’s data. If there is more than one device, then setting a single one to be opened by default would also make sense. 2. Don’t require GPS to be turned on at the smart-phone to access device data. Note, it is also accessible without GPS via wi-fi. 3. We’d love to see all of the data displayed on the device display itself (see photos comparing device display versus app display).
Measures and displays: Temperature, Humidity, VOC, Co2, Radon, Particulate Matter, Air Pressure
Manual is in 8 languages. Guess I'd expect that from a product designed in Norway.
The manual is basically a how to download the smart phone application; chase the link on Google or Apple. Easier to just scan the barcode.
The unit is about 6"x4"x1 1/2" and weighs about 13 ounces. There are 3 pieces of double sided mounting tape included and a couple of holes to use screws to wall mounted if desired. I just set it on a shelf.
C02 and VOC sensors need 7 days to calibrate. Radon fluctuates so long term monitoring is required (30 days).
Temperature, humidity and barometric pressure are accurate within a few minutes.
Internal batteries are 1.5V (LR6) alkaline x 6 (included)
USB 5.0 VDC (does not charge batteries, but the unit will switch to batteries if not USB powered). Also included about 6' long cable.
Phone application setup took about 10 minutes to create an account, activate the monitor, and connect it to my network.
The application will do push alerts if any of the monitored functions you select are "out of range".
The front of the unit responds to a close hand wave and will then cycle through the various readings on the LCD.
All recyclable cardboard packaging, fantastic!
I had a radon meter in the basement that started giving high reading. Before committing to ventilation system I put charcoal pug and lab reading came way lower. Old meter was measuring radon concentration by analyzing pulse amplitude shapes. Pulses were generated in ionic chamber. Electronics was filtering out pulses produced by ionizing radiation from particles with energy different from those emitted by radon-222. Airthings sensor is of scintillation type. Plate made from special material lights up when particles collides with it. The intensity of the light is proportional particle energy. Initially I thought that ionization chamber will outlive scintillator. But old device has micro gas tube display that glows in the dark and it's almost burned out within 3 years of continuous use. Airthings has ebook display that has unlimited live. The scintillator plate is probably going to live longer than other components or bluetooth/wifi standards that this device is using to communicate. I like Wifi and ability to store data on clouds for free. My old device only has bluetooth and uploads data directly to your phone. It takes 7 days to get radon readings calibrated. Devices also measures VOC (e.g paint or mineral spirits vapors in the air). Some floor stains may give up poisonous VOCs months after you can walk on them. Particular matter or PM2.5 sensor tracks allergens in the air. There are also CO2, humidity and pressure sensors. Everything is recorded in time so you can review history. App also allows to set alarms to notify you if air quality is off remotely. Device has a small fan that has low duty cycle to clean and ventilate sensor chambers.
