I was recently on the hunt for the best air purifier under $1,000 to buy for my new home. I wanted something with outstanding particle filtration via true HEPA filters and I also wanted odor/chemical/VOC removal from granulated activated carbon. The following is everything I've learned during this hunt so I apologize for the wall of text.
Most air purifiers with true HEPA filters will only last around 6 months before you need to replace the filter. So I set my goal on finding something with much longer filter replacement intervals. Carbon filters in most air purifiers are not substantial enough to be effective so I wanted to find one with a significant amount of granulated (pelletized) activated carbon, not just an impregnated sheet of it.
I also wanted a long warranty with a reputation for reliability and high satisfaction. Finally I discovered that most air purifiers on the market are constructed of materials that off gas, meaning they are emitting gases that they then have to try to clean, very counterproductive. So I was determined to find one that wouldn’t off gas as well.
In my research I have found that Cubic Feet per Minute (CFM) is the number that you should be paying attention to when comparing units. This is the amount of air the unit can move. Generally you want a unit that can do atleast 250CFM. But keep in mind that the general recommendation for whole house filtration is multiple units dispersed throughout.
You can ignore AHAM certifications and CADR ratings as these are misleading and there is a huge controversy over these rating systems as they are “pay to play” and are not an accurate measure of a units cleaning ability. Instead pay attention to CFM and the type/amount of filtration.
Also make sure they are using true HEPA, H13 or better. Anything else like BlueAirs “HEPAsilient” are NOT REAL HEPA! And ionizers/ozone generators should be avoided as they create ozone as a byproduct which is not good for you. UV lights are also not necessary because HEPA filters will capture viruses.
Now all this research brought me to the Swiss made IQAir HealthPro Plus. It uses a 30sqft Prefilter (18 months), a 5lb Granulated Activated Carbon filter (2 years), and a 54sqft H12/13 HyperHEPA (4 years). So in addition to these extremely long lasting and substantial filters it also has a 10 year warranty, a non-offgassing ABS housing, 330CFM capability, high reliability and customer satisfaction, independently certified HEPA 99.5% efficient to 0.003 microns (which they sent me the lab report of) and they’ve been producing this unit for over 2 decades now, so you will never have a problem finding parts or filters.
The rating on this unit at max speed (330CFM) means it can do about 2 Air Changes per Hour (ACH) for about 1200sqft.
In the end I am very glad I decided on this purifier. Even with the $900 price point I would still buy this unit again in a heartbeat! Please feel free to ask me any questions about it or the air purifier hunt in general and I'd be happy to help!

My logic is that if the air purifier is catching all the particles, then my system will become less tolerant to them over time and see them as more hostile when I am exposed to them the other times I am not using the air purifier. Any thoughts or sources supporting/debunking this?

My flatmate smokes in his room and the smell just lingers around the flat. I'm not okay with it but he's willing to get an air purifier so I've explored the option for air purifiers but just wondering how effective it is with smoke smell.
Has anyone else find air purifiers effective with smoke smell?
Afternoon,
Woken up with a sore head yet again, and sat at my desk with a blocked nose - despite not having a cold or anything.
So now I’m looking at air purifiers to see if I can get rid of the dust in the bedroom and home office - do they actually work though? Most of the Amazon reviews read like a YouTuber reading off the back of the box or someone in their 80’s impressed that they managed to plug it in.

Our bedroom is approximately 200 square feet. It is getting marijuana odor from either smoking or vaping next door. We bought the Levoit Core 300 air purifier with the toxin/carbon filter. The Levoit does not help the marijuana odor at all. Can air purifiers remove marijuana odor? If so, what is the best one?
Thanks very much for any suggestions.

So any how, casually going to ikea for about the 100000th time this week and noticed they sell air filters/purifiers
Now I know nothing, so I’m asking you if it’s good to have? Worth it? Benefits? I was thinking of buying a few and sticking them around my bungalow. But seriously. Are they worth it?
Are the filters expensive? Any cons? Do they break down?
Anything you could tell me? I was thinking about hooking them up to smart plugs and then turning them all on together. But do I need a lot of them? Or just 1-2 around the house and we good?
I’m from the uk if that makes a difference. Cheers

Hi everyone,
I am living in the Netherlands and I need an air purifier for my small apartment mainly for dust, lint and overall air quality for around a 100 euros.
I found these 3 but I don't know what to choose as am quite new to this subject:
It's a small 1 bedroom apartment but it has a lot of dust and quite stuffy

Hi there, I live in a 550 ft studio apartment and one or more of my neighbors is really aggressive with the air freshener - I smell it in every corner including the doorway, it seems to be coming through the walls*.
I have a pretty bad fragrance sensitivity and I'm miserable. I have 2 small levoit purifiers that aren't doing much, and I'm wondering if one for VOCs with the carbon filters might help. Is it possible to filter constant fragrance from my air?
*(I had my landlord come up and confirm that my apartment doesn't stink/she hasn't had any stink related complaints, so I don't think they're trying to mask a smell I'm making unfortunately.)

So as a bit of context our house is just generally dusty, we hover/dust often but it doesn't seem to do much about the dust in the air (we also have a house rabbit the moults twice a year, once at the start of the year for 6 months then half way through the year for 6 months). Just trying to find ways to get rid of dust and fur in the air which brings me to my question.
Do air purifiers help remove dust? I know they supposedly remove pollutants like car fumes and smoke (we don't smoke) from the air but would we actually see any benefit from it?
Basically are they just a fad or do they provide general improvements to the air you are breathing inside your home?
