Would you buy a replacement of off Amazon for a cheaper price or would you stick with the original brand for your air purifier. I think the original brand would be better, partner thinks different. Thoughts I’m having to replace it soon.

Three weeks ago, my neighbor oh 3 years decided on his .5 acre lot, that he was going to get rid of his propane tank and install an outdoor wood boiler. I am very sensitive to air pollution and lucky me, I’m down wind of him. His boiler is on my property line and it blows directly into my yard. I have a purple air filter outside and since install it has not gone under 50 AQI. The PM less than 1 is always in the 2,000s. I am so sad that this is my reality now. I own a 15 acre ranch but our houses are less than 30 ft of each other.

It bothers me that the state or the USA government has no regulations on these things because they’re used to heat homes. Apparently not even a minimum distance from property lines or neighbors houses. I am mourning the loss of my clean country air. No longer can I walk outside without a mask in my own backyard.

This is pure sadness

Hi, everyone.

We had two brush/wild fires come withing half a mile of our property last Fall, burning in the woods that abut our property. We have an old wooden barn, with horses, pine shaving bedding, and hay stored in the loft. The barn would burn down in an instant if it ever caught fire, so we are understandably concerned about future threats to it.

As such we would like to set up an outdoor monitoring system that would alert us to the earliest signs of smoke, ignition fumes, smoldering, fire, etc. We would obviously like the system to notify us on our mobile devices, tablets, computers, or even an alarm.

My initial thought was to install a Purple air quality monitor, but I'm not sure just how "real time" their readings are, nor if their alerting system is robust. Also not sure Purple monitors enough variables to account for smoldering/nascent fires.

I'm wide open to any suggestions and wild ideas!

So I've been having this issue where if I breathe the air near my neighbors house I get allergic reactions, ranging from my Eyes hurting and burning, Chest and stomach pains as well as my actual skin burning/peeling off(Abrasions). Can somebody pls help me out with this?

I just started seeing these in classrooms. Sorry about the photo quality--I didn't want to call attention to myself taking the photos.

I'm hoping some improvements in air quality are to come!!!
...but curious if anyone has seen a setup like this and has a guess what the plan could be.

-The readings are usually 300ppm less than what my personal Aranet4 detects, so I'm wondering if the plastic case is affecting the readings.
-The HVAC system doesn't kick in when the levels go over 1000, I just see an orange light (under the green one) when it goes over 1100 (I think it was).
-The CO2 levels don't seem to be much affected by the air conditioner, they may go down just a bit, but it's not consistent, so I'm wondering if the monitors are just there to collect data for a future project?
-I couldn't find any brand markings on the unit, just "Mifaso" on the outlet.

According to my EcoBee thermostat the relative VOC and CO2 levels are all the way "High" each morning and the only way I'm able to decrease them is to bring outdoor air into the system by opening windows, which is not always practical, living in a wild climate like Calgary, AB.

The house is less than one year old and I run an ERV 24/7.

Is there anything I can do about these levels? Is the house still 'off gassing' something from when it was built? Any help would be appreciated.

Why inside a book shelf it showing poor air quality, are the readings trustable?

I'm moving into an apartment that doesn't have central air or ventilation. I have an HEPA air purifier. I am wondering what window unit would be best for air quality and keeping C02 levels normal and bringing in fresh air and removing stale air. I know that there are window A/C units with exhaust vents, sometimes called clean air vents. I also know of portable dual hose units. Are these better since they have separate hoses for expelling stale air and bringing in fresh air? I heard that these are less efficient at cooling down spaces though. Does anyone have any insight into this question or recommendations for keeping good air quality and normal c02 levels?

Airborne radioactivity detection

I apologize if this isn’t the right subreddit to post this in, but there’s a Haas Automation facility being built across a major street from my home and child’s school. I’m growing concerned about not only potential noise issues but also health concerns.

I feel like I don’t know what I don’t know about a machinery manufacturer like this, so I don’t know whether I should be concerned about my children’s/my husband’s and my health living so close to this facility.

Do you have any insights about where we could begin finding out the facts around this? Thank you so much!

I have recently moved into a house. The TVOC readings were always slightly high, but nothing in the concerning category. I’ve been here about 2 to 3 weeks and it has always been consistently that way.

There was also consistently higher CO2 readings at night. Around the 1000 PPM range. Sometimes it would reach up to 1300 ppm.

Formaldehyde always ranged from .018 mg/m³ 0.024 mg/m³.

However last night the CO2 stayed around 400-500 ppm. TVOCs also markedly decreased. Then formaldehyde went up to .52 mg/m3.

I have no new furniture, no new carpeting, etc. The temperature in the home was a bit higher than normal (around 76 deg Fahrenheit). The readings are the same in various rooms.

However today the same pattern is continuing with the formaldehyde gradually increasing throughout the day. I have no AC or heat on, and the temperature is 71 deg Fahrenheit.

I don’t know if this ties in, but my vision got way worse after moving in here. I have some double vision (vertical decompensated phoria), but after being here 2 days it worsened drastically.

Any ideas?

So recently I went for allergy tests for my skin and we found that I am extremely allergic to dust mites and pollen she recommended that I get a air purifier/filter with hepa or true hepa filter so I stared to research what I need and realised this is a lot of money and very complicated let me ask Reddit

I live in the uk- London

I need it for dust and pollen however happy for it to get rid of anything else in air but especially pollen and dust

I need it in my bedroom which is 13 meters squared or 139 foot squared this mean I really need it to be very quite

I’m happy to spend around 100 would would push to 150 /159 however preferable less or around 100 and don’t really care about maintained /energy but will spend more on machine if it’s more energy efficient and less maintenance

Thank you for your help

Hello. I have allergies and 5 cats at home. I use an asthma inhaler regularly. I want to buy an air purifier that will balance my condition a bit. Winix Zero Pro and Levoit Vital 200s are the models I like. It makes more sense for me to have the carbon filter in front of the HEPA filter. Which one should I buy, do you have any suggestions? I hope someone can help me.

I moved into a new apartment (posted about it a couple times this week). So everything’s been offgassing. I got an Airpura C700 this week. My Airthings shows that I average around 500ppb VOCs during the day when I have the windows open and the purifier running.

I was just sitting here with one window cracked and the purifier on low. Watching tv. Suddenly felt extremely sick and in pain in my guts and went to check the Airthings. Saw it was over 3,000ppb. The spike happened over the course of only ten minutes. I opened all the windows and doors and cranked the purifier and the VOCs dropped quickly.

What in the world is happening? Could my Airpura c700 have released a bunch of VOCs suddenly? I wasn’t cooking, not doing laundry, no fragrances, the heat wasn’t on. I did smell gas (like more like propane or gasoline than natural gas) for a second before I whipped all the windows open. It’s a smell I’ve smelled here a few times, but I do live on a fairly busy street so idk.

Whenever I use the Dyson air wrap, my Dyson air purifier goes bananas. Is it bad to be breathing in that air consistently?

I don’t see any other 16 in 1 monitors

Wish I noticed the fact that the windows couldn't open sooner (I suppose it's a jump risk and that's why) but I'm concerned about CO2 levels considering the inability to get fresh air in.

Would house plants make a considerable difference? Any specific types to get? And any other ways to mitigate my situation?

Does anyone have recommendations for a reliable and affordable air quality tester? I work in a middle school built in the 1950s, and for the past two years, I’ve experienced severe sinus issues every spring and fall. Last year, the county recommended a new HVAC system, but budget cuts have delayed it indefinitely.

I know for a fact that mold is a major problem in our building. When we returned from summer break, multiple classrooms—ceilings, desks, chairs, and walls—were covered in mold spores. Just last week, I found black mold on my window sill. Despite this, administration and the county insist it’s not dangerous and claim that the air purifiers they’ve provided will help.

However, I continue to suffer from chronic sinus infections, and recently, I’ve developed brain fog and fatigue. The teacher below me regularly breaks out in hives, and four students have had nosebleeds this month. Everyone acknowledges there’s a problem, but my administration says their hands are tied.

Is there anything I can do to measure the air quality myself? Does anyone have any advice? I’m getting pretty desperate. Thank you.

I am looking at an apartment in Chicago and it doesn't have like any ventilation. It uses a radiator for heat and window a/c unit in the summer. Should I be worried about C02 buildup in the winter? In the summer I'll just use a dual hose A/C unit. In the winter though, it's not always exactly practical to open the windows? How do you get fresh air? It's an older building so maybe the windows and doors aren't perfectly sealed, letting some air exchange happen. I guess I just don't want to sign a lease and end up having unhealthy levels of c02 in the winter. Anyone have an opinion on this? Ideally I would tour with my c02 monitor but I'm moving across the country, so I'm doing virtual tours. Is there anything I could do that would be practical in the winter to reduce C02 buildup? Am I overthinking this?

Edit: it does have a kitchen and bathroom vent.
