User questions & answers

Question:	Will this detect secondhand cigarette smoke
Answer:	It will detect smoke from my cooking, but not my neighbor's cooking. I haven't tried it with cigarette smoke, but if the smoke is close enough to the device, say within 10 feet, I think it will.
Question:	Will this detect leaking gas from a stove or heating unit
Answer:	No > You need a Carbon Monoxide detector for that. < That is a safety device you should have just like a smoke detector. Carbon Monoxide (from faulty stoves or furnace) is much more dangerous at lower ppm. What you get with this air quality monitor is readout on carbon Dioxide, which humans breathe out (and generally is not harmful in low parts per million, but when a house is tight / lots of people together it starts to get stuffy and signals need to open window for fresh air, etc). House Plants can also help process that co2 into oxygen.
Question:	How does it charge, Is it battery operated
Answer:	AC
Question:	How accurate is this product when compared to, say, a fluke
Answer:	I've never used the fluke, but seeing as how it looks like a professional device, I'd say that this device will not give you as accurate a calculation on particulates. It has basically a 1-5 scale for particulates, and only measures pm 2.5 particles. Plus a separate scale for VOCs. I've been using mine for about 2 weeks and see it drop down from an overall score of 100 to about 65 when I cook, but I bought it to detect fumes from my neighbor's cooking, and even though I could clearly smell their smoke, my awair was still registering at a 95, so it didn't really do what I had hoped.

Product description

Have you gone nose blind to household odors?

Check multiple measures of your home's air quality. This air quality monitor has a fan onboard that allows REAL-TIME accurate monitoring of formaldehyde (HCHO), total volatile organic compounds (VOCs), and <2.5 micron-sized fine particulate dust (PM2.5). Formaldehyde is an environmental carcinogen yet odorless at lower concentrations that can off-gas from various building materials. Detect low levels of airborne organic compound and odors or VOCs emitted from biologic and synthetic sources such as plastics not perceivable to the human nose. Check microscopic inhalable dust levels with PM2.5 levels.



Problems with allergies?

See when you may need to change your home’s air filter. Watch the levels of formaldehyde and VOCs drop when the windows are opened. Learn where air quality is poorer and where your allergies can worsen. Allergies that are difficult to control with unexplained coughing, runny nose, and shortness of breath may indicate sick building syndrome.



Tips on Use:

-PM2.5 reads in μg/m³, not AQI; search AirNow AQI calculator online for conversion.

-Large variations or 9.999 TVOC readings do not indicate an error as this instrument is a sensitive electronic nose; environmental TVOCs vary much and high TVOCs often can result from interference from benign fragrances or odors.

-Calibrate if 0.000 indoor readings noted or with new device.



Specifications:

-2.8” 240 x 320 LCD

-2200 mAh Li battery; DC 5V micro USB charging

-HCHO Range: 0 - 1.999 mg/m3

-TVOC Range: 0 - 9.999 mg/m3

-PM2.5 range: 0 - 999 μg/m3; PM10 calculated from measured PM2.5

-Adjustable alarm for various HCHO levels and auto-shutoff timing (up to 2 days).

This air quality tester detects organic compounds like formaldehyde which has suspected links to nasal cancer and lung cancer emitted from many household materials. By measuring particulate pollution, an air pollution monitor can also help you know when asthma may worsen and when to change your home’s air filter.
• ORIGINAL DESIGN & USA BASED SUPPORT – We have Midwest-based technical staff including a chemist to answer any questions you have. Also included will be a 20+ page eBook on Gas and Air Quality Hazards. We have worked with the supplier that holds this air quality detector’s design rights so you can be confident this item is tried and tested.

User questions & answers

Question:	Does anyone know how to get the ebook
Answer:	The eBook should be attached to the email we send to all our customers. Let me know if you don't see it attached to the email sent by us through Amazon's email message service.
Question:	Can this monitor be used for outdoor air quality monitor
Answer:	The monitor can check for outdoor particulate matter (PM2.5) levels; TVOC and HCHO levels are generally negligible outdoors as they are from synthetic sources.
Question:	In testing for formaldehyde & you have a certain product do you place a plastic bag around the product and insert the tester inside
Answer:	That is a very good question: 1. What I would do is place the tester in the bag without any product to get a baseline and then place the item to be tested in the bag for about 1 day to achieve equilibrium. 2. Then you can put the tester in the bag for at least 30 minutes or until readings stabilize. 3. Subtract the tested item reading from the baseline reading to get the formaldehyde emission amount from the tested item. Hope this answers your questions, take care!
Question:	Does this detector work for checking for mold
Answer:	It can check for TVOCs (organic compounds dissolved in air) and PM2.5 (micron dust levels) which can indicate presence of mold but it does not specifically check for concentration of mold spores. Thanks for asking.

TVOC Detection

TVOC (Total Volatile Organic Compound) is one of the main pollutants of home decoration pollution.

M10 can detect the content of various volatile organic pollutants such as benzene toluene, alkanes and aromatics to protect you and your family's health.

Formaldehyde (HCHO)

HCHO is a colorless, poisonous, highly water-soluble gas with an obnoxious odor. Used in the manufacture of disinfectants, preservatives, and hundreds of industrial and consumer products such as adhesives, carpeting, decorative paneling, foam insulation, drapery, fiber and particle boards, and permanent press fabrics.

Carbon Dioxide (CO₂)

CO₂ is a greenhouse gas that is natural and harmless in small quantities but as levels rise it can be dangerous to your health. Most commonly produced by the air we exhale, CO₂ levels concentrate indoors with less ventilation.

Exposure to high carbon dioxide levels can cause:suffocation by displacement of air, incapacitation and unconsciousness, headaches, vertigo and double vision, inability to concentrate, tinnitus, seizures.

Air Quality Index (AQI)

The air quality index is the extent to which the air is clean or polluted, and the impact on health. Mainly through five pollution standards: ground ozone, particulate pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, nitrogen dioxide.

User questions & answers

Question:	Does it detect and/ or measure hcho (formaldehyde) levels, too
Answer:	Hi there! Thanks so much for your interest in the Wave Plus and your question! The TVOC sensor in the Wave Plus will detect formaldehyde as part of the TVOCs (total volatile organic compound) measurement but keep in mind it does not give a breakdown of each VOC in the air, but the total measured amount. If you have any other questions just reach out to our support team on the Airthings website, we'll be happy to answer any questions! -Tom from Airthings Support
Question:	Are any gas voc's checked
Answer:	Hey! Hey! Our TVOC sensor will indicate the total amount of gaseous chemicals in your environment. Please check out our Help Center on the Airthings website for a breakdown of VOCs. Common sources of VOCs are as follows: Candles and fires Anything that burns gives off fumes. Fireplaces and scented candles are especially harmful, so keep an eye on your levels while using them. Fragrances Mothballs, room deodorizers and perfumes—anything with a fragrance, contain chemicals that should be avoided. Cooking fumes Cooking also creates gases that can be toxic. Always use a hood fan or open a window while cooking indoors. And keep the door closed when grilling outdoors. New furniture New furniture, carpet, drapes, mattresses all contain chemicals that slowly release into the air, often for years after you bring them home. Cleaning products While cleaning with soaps, detergents, furniture polish and glass cleaners be aware of terpenes and ethanol and ventilate accordingly. Craft products Glue, paints, fabrics, wax, dyes, many craft products contain VOCs. Be sure to ventilate while using them. Children's toys Some hard plastics contain formaldehyde, and new fabrics emit toxins into the air. Look for BPA-free plastics or avoid plastics altogether, and wash toys before using them. Paints and varnishes Lacquers, paint, industrial glues, paint thinner and harsh chemicals should not be kept in the home, even when they are locked tight they emit chemicals into the air Please feel free to reach out to us via the Chat function on our website if you have any further questions or concerns :)
Question:	Does anyone have the Wave Plus installed in the basement? I have a finished, wide open basement (no dividing walls) about 1000 square feet in area
Answer:	I installed mine in the basement since that is where readings are typically the highest.
Question:	does it measure PM 2.5 and
Answer:	Hi there! Thanks for your question. Our Wave Plus doesn't measure PM particles, so it doesn't measure PM 2.5 or PM 10. The Airthings Wave Plus measures CO2 (carbon dioxide), TVOC (airborne chemicals), Radon, temperature, humidity, and air pressure.

Product features

Radon

Radioactive gas, invisible, dangerous, found in every home. As radon levels fluctuate daily, the only way to ensure radon levels stay low is by long term radon testing.

Carbon Dioxide

An exhaled gas impacting sleep, health, and productivity. Occupancy and daily activities can increase carbon dioxide indoors, using a co2 detector can help you adjust ventilation accordingly.

Volatile Organic Compounds

Volatile organic compounds- (VOCs) are toxins found in everyday items including cleaning products, furniture and paint. Our Total VOC sensor alerts you to high levels of a long list of chemicals. To keep levels low make small adjustments like using VOC free paint or installing a VOC air purifier.

Humidity

Humidity. Moisture promotes mold while dry air can lead to cold and flu. To get the best indoor humidity level for your home, monitor daily.

Temperature

Temperature. Affects sleep patterns, mood, comfort level and alertness. A temperature sensor is a necessity for every home.

Pressure

Pressure. The weight of the air can cause headaches, joint pain and fatigue. The barometric pressure of the atmosphere changes depending on elevation and weather patterns.

Be protected.

Radon is the leading cause of lung cancer among non-smokers, according to EPA approved estimates. Ensure harmful radon gas levels stay low by monitoring daily.

Breathe easy.

Know your air is free of toxins and chemicals (VOCs) found in everyday items. VOCs can cause serious health effects when you are exposed over both short and long periods of time.

Perfect balance.

Make sure humidity levels do not rise too high or fall too low. Optimum indoor humidity levels are between 30% to 59% according to the EPA. Healthy humidity levels are key to prevent mold and the spread of infectious disease.

Question:	Need to check the air quality in the interior cabin of my car, concerned about exhaust fumes and other harmful fumes, is this unit sufficient
Answer:	Please don't make a mistake. This Air Quality Monitor does NOT measure carbon monoxide (chemical nomenclature "CO"). Carbon monoxide is one of the most deadly components of exhaust fumes from a gasoline-powered engine. If you don't measure carbon monoxide in your car cabin, your overall air-quality measurement is INCOMPLETE, and it could be a deadly mistake. There are gas-detection monitors on Amazon that measure for carbon monoxide.

Question:	Does it tell you if the dust count is high ? How do know why air quality is bad
Answer:	Yes, the BREATHE|Smart 2 monitor measures dust levels using an accurate laser-based particle sensor which uses the light scattering method to detect and count particles. The readings are instant so you can easily see when levels of dust are increasing or falling. The levels can be displayed as an index or the actual concentration of particles in the air, and there is an indicator on the display to show you if the levels are good or bad. Additionally, the side glow the corresponding colour (eg green for good, red for bad) so you see at a glance the current conditions.
Question:	Does it meansure hcho and/or tvoc
Answer:	BREATHE|Smart 2 measures PM2.5 particulate air pollution, it does not measure HCHO or TVOC
Question:	Does it measure tree pollen
Answer:	Pollen spores are basically a type of particulate matter but they tend not to fall into the category of PM10 or PM2.5, as they are usually larger. This monitor is therefore not recommended for measuring tree pollen.
Question:	does it measure carbon monoxide
Answer:	This monitor does not measure carbon monoxide. It measures particulate pollution, specifically PM2.5 (particles less than 2.5 micrometres in diameter). These particulates are the deadliest form of air pollution due to their ability to penetrate deep into the lungs and blood stream. Sources include vehicle emissions, factories, construction sites, burning of fossil fuels. grilling food on charcoal or gas grills, burning leaves, smoking cigarettes, and burning wood in fireplaces or stoves.
