r/AirPurifiers

Hi All,

I am looking for the best possible Air Purifier I can get for this budget for my bedroom. I want it to be able to tackle pollen, dust and odors (nothing too bad, mostly cooking). my bedroom is roughly 150-200 sq.ft. I am not too concerned about the annual maintenance as long as I don't have to replace the filters every week or so.

My litter box is in an alcove area between my kitchen and family room. It’s about 6x6’ room with high ceilings.

I want to get an air purifier but I’m wondering:

1. Is it okay to put it across the room?

2. Is it okay to elevate the purifier on a desk, or does it need to be on the floor next to the box?

3. Can I get a purifier for a small room given that this area is pretty open to other rooms?

Hi everyone, I'm looking for recommendations for the best air purifier available in Italy/EU to use it in my bedroom.

I recently bought a traditional Japanese tatami (rush grass/igusa + pressed straw) and a raw carded cotton futon. The natural herbal aroma/VOCs and fine cotton fibers are causing my brother (who has a history of hyper reactive nasal turbinates) to wake up every morning with a blocked nose.

My bedroom is 14 m² (~3.9m × 3.5m with standard 2.7m ceiling) = ~37 m³

Whole apartment: ~80 m² = ~215 m³

My budget is 200€ but I can spend more if the price is justified. Thank you.

US based, 1800 sq ft home, 2 dogs (one short hair one long), and 2 cats (also one short hair one long). My partner has terrible allergies to both cats and dogs (I know - but she loves them!). I’m looking to get an air purifier per floor (3). Preferably $500 or under per unit. Would also love if it had a reusable filter, but the main goal is making sure my partners allergies improve and they feel better. Thank you!!

Hey all!
Im looking to add purifiers to our bedrooms; two of the rooms are 120 sq ft while the 3rd is closer to 175 if I’m guess correctly. i have 3 kids and two indoor cats so am needing general pollution, dust,and allergen control. I need something affordable ( $100 per unit with $75 monthly for filters) but dependable and was looking at this model as its on sale- the official title is Levoit purifier for home pet hair allergies in bedroom
It’s a core 300 P and says it covers up to 1000 ft.²
I don’t know anything about purifiers outside of what I’ve read on here and a friends recommendation.
TIA!!!

Edit to add I’m in the US!

if you own air fanta 3 pro, how long before the smell went away? i have a new one i have been running for about 8 hours on high in a spare room. it is still smelling. sigh. what do you do?!

Moved to CO from MN recently and am in desperate need of a humidifier. With thousands of options online - wanted to see if anyone had any good recommendations for Colorado weather. Ideally ones that won’t cause mold issues.
2 bed apartment, 1200 sq ft total

Source cannot be reasoned with so I'm just holding my breath whenever I have to leave my room. Mobile home. Main concern is the living and kitchen areas. In the evening it's OK as it cools down enough to open windows, but it still smells. During the day it's too hot. Budget is maybe $1-500? I don't really know a lot about air fresheners and stuff outside of basic tower and box fans for cooling.

country: usa

edit: she hasn't peed the carpet but she's peed her pyjamas several times and she refuses to wash them and everything is a fight with her, so she reeks up the area just by being in there.

I just moved to a new apartment building on the third floor with windows all facing a busy 4-lane street. I am the type that usually loves to keep my windows open, and am concerned about doing so next to such busy street with all the particulate matter being kicked up. It is just me and my partner living here, both relatively healthy adults, but I want to make sure my body lasts me a long time!

I am researching what air purifier would be best for this situation? The apartment is small, about 800 sf across two main rooms separated by a door, with ~8' ceilings. The bedroom is carpeted.

So far, I have looked into Coway, Winix and Blueair. The blueair medium spi3 is the strongest candidate that I've looked at, but of course there's been lots of conflicting opinions and information on what's best. Please let me know if you have tips or recommendations for this situation!

Additionally, noise levels aren't a huge concern -- the busy street is noisy so I welcome some white noise to cancel it out. Budget is flexible, willing to splurge a bit for quality filtration, ideally <$500 with <$50 per year for filters, etc.

I’m trying to understand a specific asbestos/HEPA-filter scenario and would appreciate input from people familiar with filtration or asbestos exposure. I used a Levoit Core 400S for roughly two months after it had previously been used in an renovation environment where asbestos-containing material have been disturbed. (didn't know at that moment about content)

My concern is that if asbestos fibers were captured by the filter, could some of those fibers later detach or become re-entrained during normal operation, changes in airflow, low-level vibration, or handling of the purifier? I’ve come across studies reporting re-entrainment from loaded HEPA filters, but the experimental conditions seem to vary considerably.

I’m particularly interested in whether those studies are realistically applicable to a household HEPA purifier operating under normal conditions, and whether fibers that were previously trapped in the filter could realistically produce a meaningful airborne concentration in the room, and if so, what levels could be?

I'm in USA. The bedroom itself has a floor plan of 15ft 5in (length), 16ft 3in (width), and the ceiling height can go to 9ft 7in. Don't really have much money to throw around, but the house gets a lot of dust and I'd like to fight off some of it with a purifier while wiping down surfaces. What are my options?

We have had Mila air since 2020, we were attracted to it because of the sensor suit and how you could chose the filter that worked best for you.

Our first unit needed replaced almost immediately because the AQI would not move even with a candle burning right next to it. They did replace it under the warranty pretty easily. This unit lasted a couple years and then one day it shut itself off and would mot come back on. At this point I was out of warranty but due to be subscribed to the filter replacement service they offered to replace it if I sent the defective one back and paid 100 bucks which I did. Now a couple years later I just started having this issue where my AQI spikes and crashes like a roller coaster all day long but the falls and stays at zero all night. The unit is in the same place it has always been in with no new humidifier or anything like that so these spikes just don’t make sense. Not to mention they just started a few weeks ago (right after my last filter change) and do not happen once so ever during the night time hours.

i have always know Mila’s temperature and humidity readout to be incorrect but I just live with it as i have a separate thermometer in the room. I’m just wondering has anyone else had this issue? Does anyone have ideas as to what it could be? Or does anyone have a unit they suggest that would replace the Mila with similar data feed back.

Before anyone gets excited, yes my furnace was designed for a MERV 16. It’s a Lennox high efficiency system with their PureAir system that has a MERV16 filter and uv-c light I get good air flow through it and haven’t destroyed any blower motors.

It did very well recently when we had those Canadian wildfires. I’m in Chicago and didn’t smell anything inside.

Im going cross-eyed researching air purifier, help!

Im in NW Florida. Open concept living/dining/kitchen. 640 sq ft. Three cats that used to be outdoor, now indoor with litter boxs since we just moved. I’m looking for a system that will keep house from smelling like cats, odors from smoke when husband is clearing/burning outside and comes in stinking like smoke, help with asthma/allergies AND a long lasting/affordable filter. I understand I need a good carbon filter. I’d like to keep it around $200 if possible. I’m considering the following so far… Coway Airmega Mighty, Winix 5510, Levoit Vital200s. I have a Levoit Core mini-P in my laundry room and it really helps with litter box and laundry odors. Thanks for your advice
