Product description

Have you gone nose blind to household odors or dust?

Check multiple measures of your home's air quality. This air quality monitor has Wi-Fi capability that allows REMOTE real-time monitoring of temperature, humidity, formaldehyde (HCHO), total volatile organic compounds (TVOC), and micron-sized fine particulate dust (PM2.5/PM1.0/PM10). Monitor your air quality using the large 4.3” display or remotely from any location using the Tuya Smart app on your smartphone.



Problems with allergies?

See when you need to change your home’s air filter. Watch the levels of indoor total volatile organic compounds and formaldehyde drop when the windows are opened. Formaldehyde is an environmental carcinogen yet odorless at lower concentrations. Detect low levels of airborne TVOCs not perceivable to the human nose.



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 be signs of sick building syndrome.



Tips on Use:

-Download the Tuya Smart app from the Google Play or Apple App Store to monitor data remotely; monitor connects to router/hotspot.

-Large variations & 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.

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.

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:	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.

CO2 (Carbon Dioxide)

Carbon dioxide is a colorless, tasteless gas that is heavier than air and the gas itself shows little toxicity, but suffocation is possible. If the amount of carbon dioxide is higher than the amount of oxygen circulating in the brain, the respiratory disorder, headache, tinnitus, and blood pressure will rise.

Risk of CO2 is as follows;

1. 450ppm or less: It is outdoor air in ordinary everyday life.

2. 450 ~ 1000ppm: The air is clean and there is no big trouble in breathing.

3. 1000 ~ 2000ppm: The air becomes cloudy and sleepy.

4. 2000 ~ 5000ppm: My head hurts, I get more sleep, I lose my concentration, my heart rate gets faster and I have a slight vomiting reaction.

5. 5000ppm or more: It can lead to permanent brain damage and even death in severe cases.

VOC (Volatile Organic Compounds)

VOC (Volatile Organic Compounds) is a hydrocarbon compound that volatilizes in the air and generates odor and ozone. VOC is mainly found in the manufacturing and storage processes of petrochemical refining coating plants, building materials such as automobile exhaust, paints and adhesives, and storage tanks of gas stations. Benzene, formaldehyde, toluene, xylene, ethylene, styrene, and acetaldehyde are part of VOC which is well known.

VOC is a toxic chemical with a carcinogen that causes damage to the nervous system through skin contact or breathing inhalation.
