They help a lot, though I still need to air out a few times a day aswell.

Hey. Im going to paste a comment I made on previous threads thats still accurate to date for me at least. Giving some context first which can help in understanding my recommendation and decision in air purifier. So I'm an American living in France the country where smoking in apartments is normalized. Our downstairs neighbours; a 70+ retired woman and her 50+ son/husband ¯\_(ツ)_/¯ not sure what he is to her are chain smokers and the apartment complex is 100+ years old but refurbished. The cig fumes were infiltrating through every porous crack a build can have, cracks from shared walls, gaps between side panel and floor, the hardwood floor, the vents for the pipes of water heater, plumbing and stairwell. For our needs (and the reasons should match your needs as well) I decided on going for multiple air purifiers for our two bedroom apartment so that all areas of the home were covered vs one really big one. Look at the suggestion list of what to look for in specs of the air purifier and see which are most important for you. These specs below are what I wanted in my air purifier. • ⁠True HEPA (H13 or H14) — must capture fine construction dust (PM2.5, PM10), cement, silica, and urban pollution. • ⁠High CADR rating — sized correctly for each room; don’t undersize. • ⁠Strong pre-filter — washable or easily replaceable to catch heavy dust and extend HEPA life. • ⁠Activated carbon filter (thick, high weight) — for traffic fumes, VOCs, and construction odors. • ⁠Sealed filtration system — no air bypass around filters. • ⁠Room-specific units — one purifier per room; avoid relying on a single central unit. • ⁠High airflow / multiple fan speeds — to handle constant particulate load. • ⁠Air quality sensor + auto mode — to respond immediately to pollution spikes. • ⁠Quiet operation at high throughput — especially for bedrooms. • ⁠Readily available replacement filters — frequent changes will be necessary in dusty areas. • ⁠Energy-efficient continuous operation — designed to run 24/7. • ⁠No ionizer or ozone generation — avoid added indoor pollutants. I first bought the Rowenta Intense Pure Air Connect XLfor $170 (wouldn't recommend) then I went with three Coway Air Mega 150's and paid $150 each for them. The reason I don't recommend Rowenta is because the fan settings were not controllable in the linear sense. The four modes were Daylight (It auto regulates how fast or slow the purifier fan spins based on what it detects in the air), Night (Keeps fans as quiet as possible with the occasional spin up based on what it detects), Silent (Spins the fan as slow as possible mainly used during sleeping and similar to Night mode), Boost (Maximum fan speed at all times). Also, the sensor unit for the quality of air on this purifier has always maintained "dangerous pollution levels" the entirety of owning it and after having bought the Coway purifiers after, we concluded the sensor on this one being somewhat inaccurate. It was nice being able to control the purifier via app which was a headache in its own right but now is irrelevant because we have all the purifiers running 24/7. I recommend the Coway and am happy with the purchase due to keeping the purifiers running 24/7 uses 6 watts of power each on Speed 1. The sound the purifier makes is more than tolerable as it's a gentle hum. The Pre-filter is extremely easy to take out and clean. It came with Activated Carbon Filter (A must for us in regards to filtering the cig fume smell). It doesn't leak dust from the sides of the purifier and the purifiers match our house decor which doesn't hurt. We went with the color white. And buying a filter change for them is $50 each which is in line with standard filter costs and you can go cheaper if needed via third party and non activated carbon filter. Finally, the sensors on the purifier have all been consistently accurate in detecting a change in air quality across all three devices. You can read more about this purifier at this review. The review unit came with Impregnated carbon fabric and not activated carbon which it seems will be different depending on where you buy the machine. Mine in France came with activated carbon but other markets might have something different. Hope this helps and this took a lot longer to write up than expected. Feel free to ask any questions since I went more stream of conscious for this write-up.

Regarding whether to change your HEPA filter, I would say you still have 3 months of continuous use before it requires changing. I determine this (in my opinion) from the lack of dust particle build up between the fins still having space for more dust particles to collect. A year of non-stop use I would say your air is relatively clean for the most part. I deal with HEAVY chain smokers with our downstairs neighbor. I own 4 Air Purifiers all with activated carbon filters along with HEPA filters here in France. Long story short is their cig fumes come through every crevice and crack of our floors, walls, side panels, doors, etc due to poor sealing of an old apartment complex despite the apartment being refurnished and renovated. That being said, we sealed all the cracks and pores during the past 9 months and it's safe to say that window venting method is still superior to any multitude of air purifiers and carbon filters you may have when it comes to filtering out cig smoke / residuals. Purifiers help certainly but using the ability to straight up remove the fumes from your interior is the most effective hence window ventilation wins out but the purifying and filtering of your air certainly doesn't hinder the fight. I own 3x [COWAY Airmega 150](https://www.amazon.de/COWAY-Air-Purifier-Allergy-Sufferers/dp/B08YZF8LJS?th=1) and 1x [Rowenta Air Purifier](https://www.amazon.de/-/en/Rowenta-Purifier-White-white-PU6080F0/dp/B078XXGMVV/ref=sr_1_4?crid=2TZUAKJI1HH&dib=eyJ2IjoiMSJ9.WoFzU0wwVHsWY-bhz3VvgjvMPSUx2cGJL9afBtxSxx46UiYoW5A9vWrHUGS3WdEtU6Xj20opaqau_xU2Ey3I-CbbCeOjTkcQOrNfC0rUCxsM9DWQ4BVfMh71USKlD0FyoJtZ8pxB-fUwyhvE1VI9g0jkXEGPOMaFigWSdJhEBYRij0nY2TQy9ky2G4jC7lFiHLKYvsN4WuGTwS9bbB9V5-uz89_Nx7Ej_fFiQs6bLyk.-qK2f-355bPA0vr_btY8ASRzfLhn6eXThhATjUDhjLk&dib_tag=se&keywords=rowenta+air+purifier&qid=1770041943&s=kitchen&sprefix=rowenta+air+purfie,kitchen,161&sr=1-4) specifically for the Cig Fumes that do come inside our apartment now only from common stairwell through our main door. The purifiers are situated in 1x in bedroom same size as yours. 1x Living Room, 1x Dining Room, 1x Bathroom.

I tossed up with the Vital 200S and Coway Airmega 150. Went with Coway. Great brand reputation and True HEPA.

Noise is an important aspect to consider. A noisy filter will likely never be on. It's not just about sound level. It's about how annoying/soothing the sound your filter produces is. On this aspect I l like Coway's airmega 150 and 240. It's also easy to find replacement filters for these models.

I bought two air purifiers just last week after reading this sub! Coway 150 and ap-1512HH(W), they were on sale on Amazon.ca and I read somewhere I can use the carbon pellet filter from the AP-1512HHS in the non S version. So far so good!

Dude, your knowledge is incredible! May I pick your brain a little? I live in Dubai. AQI is 50-150. When it's 50-100 it OK. When it goes to 150 and above, I feel my purifiers cant handle it. 2.5 particles are the main issue. Mainly from the desert, construction and traffic. Right now a lot of outside air gets sucked around doors. Next week I will have worked fixing it, setting up proper air-intakes with a simple filter (better than around the doors) that I can easily change. From there, it goes via AC system (basic filtering) + same basic filters on ducts. Our house is 1700sqf, I have Levoit 600s (living + kitchen), x2 Coway Airmega 150 (one in each bedroom) and one Dyson (we dont use it very often). As mentioned, when air gets bad, I feel they dont do enough, even if I set them to highest settings. I hope my paper-filter solution will help. However, Im considering adding another purifiers. My two concerns are - it will eat up more space + it costs money. I dont mind paying if I have to. Im pretty happy with Levoit. Coways - not so much. Two of them need to clean less space than single levoit, but doing much worse job. So I was thinking to add either another Levoit or maybe BLUEAIR Blue Signature. Which one would be better for 2.5 particles?

Yes they are worth it imo. My coway 150 is a workhorse. Also clean the box daily and do NOT use scented litter. In my experience, scented litters amplify normal cat poop smells. Maybe because those with perfumes are meant to have a greater reach? I dunno. They can also be terrible for cats with respiratory issues

I got the Coway 150 as well. What do you think of the Green HEPA?

Using a Coway Airmega 150 since 2021. No issues till now. It's not used daily but I've kept the dust filter clean and never had to bother with the carbon filter. Replacements look readily available.

I’m immunocompromised and always have an air purifier (Coway AirMega 150) running next to my lectern. It’s nearly silent on the lowest setting. I also have a larger one at home (250?) that is EXTREMELY loud, so I wouldn’t recommend a big one. The building I teach in is pretty modern, so I have to assume that the ventilation is quite good even though my classroom doesn’t have any exterior windows. I’ve been told many times I’m quiet/soft spoken (despite feeling like I’m always yelling), so masking while teaching is out of the question for me. I also tell my students on the first day of class that I am immunocompromised and therefore that if I do get sick, I am likely to get very sick and be gone for several weeks (sometimes I include the fact that my body literally cannot make antibodies, which is super fun). This info seems to stick with them, as I’ve had many students email me to let me know they’re sick and staying home because they remembered what I said. I am also pleasantly surprised that most students wear a mask for a few days when they return. I never mention masks at all and have never asked for anyone to wear them, fwiw. I also have a couple bottles of hand sanitizer in the room and use it very, very frequently (literally any time I touch a shared surface). I follow the same precautions in my office. I’ve had COVID three times, and two of the three times it was during the summer (I don’t teach summers). The third time I’m 99% sure I got it at a concert. Your mileage may vary, but I feel like my strategies work fine for me and at the very least give me peace of mind.
