r/AirPurifiers

He mentioned that he never recommends patients to invest on air purifiers because the benefit they bring is not worth it. I was ready to buy an expensive one because I thought it'd significantly improve my allergy symptoms, but that made me change my mind.

I have the Levoit Core 300 and been running it for years. It catches stuff i guess. Filters are dusty. However, now in the winter here in Spain, I am getting cooked unless I open the doors. I try to not abuse HVAC because it dries up the air.

So basically my question is. If I run the Levoit Core 300 at Speed 1 in a 3x3 meter bedroom, am I getting any benefits from this, or because the room is open and the speed is mode 1 and not max (3) is this not really cycling air fast enough to really make a difference?

Thing is, anything above mode 1 is too noisy. I don't really understand how people use air purifiers past a certain noise level. And for sleep forget about it. I really have to turn it off. Plus im worried this thing delivers electromagnetic waves of some sort. In Amazon comments someone measured this and apparently some of these air purifiers deliver a ton of stuff of this nature. I guess nothing radioactive but something to consider that may disturb your sleep beyond the noise?

Anyway let me know thanks.

So I read the sticky on dust, but I have a bit of a unique situation. Most people were asking about air purifiers to remove dust from their whole home, or the whole room. I am looking at collecting the dust right next to me.

So, my wife decided to start the weirdest hobby I've heard of. She buys old sweaters at the thrift store, washes and sanitizes them, and then takes them apart to reclaim the yarn. She started this as a cheap alternative to score some yarn for her own projects. Now she's taking them apart and selling the yarn online. But I digress. So anyway, right where she is actively taking them apart, it gets extremely dusty, and covered in little fibers. She was blowing her nose yesterday, and it was blue from the sweater she had just taken apart.

Are there any good solutions to this, or does this still fall under the, "air purifiers don't do dust" thing. I was just thinking since I just need it to do a little area, right next to the sweater breakdown, that maybe this could be possible.

If it is, we'd love for the filters to be rinseable, as the fibers, I'd imagine would build up rather quickly, and somewhat quiet. Working right next to something loud would probably get annoying.

Thanks in advance!

Edit: we are in the U.S. budget could go up to 500 or so, and yearly budget ¯_(ツ)_/¯. Just really trying to see if this is even possible.

Canada.

3 rooms: 1768 cubic feet living room/kitchen, 984 cubic feet bedroom, 1016 cubic feet bedroom.

Filtration needs: pollen allergies, mold, wildfire smoke once a year.

Budget: no budget really. Care more about replacement filters not being crazy expensive. Also looking for energy efficient models as we don't have a ton of amps to spare.

Bought three Coway Airmega Mighty2 but they're way too big for my small apartment. I really like how easy the prefilter is to clean though, so looking for that feature. Also looking to only change the HEPA filter once a year max.

Looking for a small footprint air purifier that can fit on a shelf and "disappear".

The alternative is that I keep one of the Airmega Mighty2 in the middle room that connects to a bedroom on each side. But I don't think people in this Reddit like one air purifier for multiple rooms?

Hello! I’m not looking for a magical purifier that will catch all of my rabbits hay particulates, fur, and smell because that is unrealistic, but are there any specifics you guys recommend for this scenario? Or features I should 100% have? Thanks!

I found this HEPA air purifier and the main reason I want one is because I want to filter the air in my room from my 3D printer (ultrafine particles). The problem is, I’ve never heard of this brand and searching Reddit, there are no results. Is this a good buy?

After watching a bunch of videos, it seems that generally people recommend levoit 200s. I don't have any pets, will it be "overkill"? I have sensitive nose that will make me sneeze, nose block etc.

Is this a good model to get for my bedroom? In my country it is around 239.25 USD

In USA; 1000-1200 sq ft space. I am not on a budget with this request, long story short I just adopted a very healthy senior kitty. He is 15 years old and I live in a dry, dusty, hardwood apartment. I do my best to sweep and keep it as dustless as possible, but my little guy keeps sneezing more than I am comfortable with. I am open to a lot of suggestions as I have never gotten a purifier before. Thank you in advanced!

I have an air purifier in my bedroom, but I still wake up with kind of a "hoarse" throat, like I've been inhaling dust the entire night.

My situation is this:

My bed is placed between an open window and the door to my bedroom. There is no other possible placement-option for the bed.

The air is so bad in the bedroom that I have to have the door and the window open to have decent air in there.

Reasons if you care: no ventilation (except the window), old house, basement air comes up if it is "negative pressure" in the house because of certain weather, walls covered in drywall that doesn't "breathe").

My air purifier is at the moment placed close to the end of the bed, because I think that will draw the dust away from my bed, however, I see on the bedside table that a lot of dust collects there, probably because the bed is placed between the door and the window. Again, there is no other possible placement for the bed. There is not any space for the air purifier to be placed anywhere between the bed and the door.

Where should I place the air purifier? Outside of the bedroom dor?

Bye bye

live in a rather humid country which has summer year round and windows are constantly open. dont use air con that much. what would be a good purifier for a room only (perhaps about 12m^2?). budget would be mid-range maybe 200-300USD or cheaper if possible. hopefully maintenance is low too (less than 50usd a year) is it fine if the rest of the house does not have a purifier? do i need to keep my door closed? if not should i buy a purifier for the rest of the apartment too?

thank you!! sorry brand new to this purifier stuff hope to gain some knowledge.

room in question, about 275sqft, 12ft ceilings.

Hi all, we are in the US and need an air purifier for our office room due to birds. We just rescued a cockatiel who makes a LOT of dander and we don't want to cause lung issues for ourselves (this is our third bird and won't be our last). The room is pretty large with about 12ft ceilings. We CANNOT have an ion or ozone machine AT ALL, I do not even want one that has the option whatsoever, as it can kill birds. I don't want it coming on by accident or anything. We also have two gaming PCs in the room, one of which is used for WFH daily.

Can anyone recommend a HEPA purifier that would work in this room decently to help cut down on the bird dander etc.?

US, 12 ft ceilings, 275sqft (3300cuft); need to filter bird dander and VOCs, pollen, dust, etc. are a bonus; NO ION/OZONE OPTION AT ALL. Budget around $300USD for unit, idek what a reasonable yearly budget for filters would be.

Thanks!

This may be a dumb question, but we have an office where me and my wife like to sit and study and that room during the summers can get quite stuffy. We live in TX and our HVAC isn't the best but it keeps that room closer to 76-77 in that room even though we have it set to 72 in the house. It's one of the rooms on the far end, however we do have a ceiling fan running 24/7 in there just to make it more comfortable. We have a Levoit pet 350-P in our bedroom, but wondering if I move it to that room, would it help increase the comfort via air circulation?

There are some old discussions about this topic. I am skeptical of filters other than True HEPA. On the other hand, when I asked an AI about NanoProtect HEPA, it said it is better than True HEPA. According to Gemini, Philips NanoProtect HEPA passes DIN EN 1822, MPPS, ECARF, and ANSI/AHAM tests.

​Do you know anything about this topic? What is the user experience with Philips NanoProtect HEPA?

So im wondering if a HEPA filter for about 50 dollars would actually do something against my dust and cat allergy, every morning i wake up and have to endure an allergy episode and it's actually pissing me off.

Hi everyone,

I had a significant mould issue in my house, with a lot of aspergillus. I’ve spent the last two years remediating it.

The house is a five-bedroom double-brick home in one of the driest parts of Australia. As far as I can tell, all active mould has been gone for at least a year. The issue now seems to be residual contamination. I suspect I’ve become highly sensitive/allergic to remnants such as spores, mould fragments, contaminated dust, or possibly MVOCs/residue associated with the previous mould issue.

Whenever I spend time in the house, I tend to get a histamine-type reaction afterwards and feel wired/anxious. The severity seems to correlate with the dust/particle load.

About a year ago, I could barely spend any time inside, so I started trying to reduce the particle load. At first, air purifiers seemed to make the air feel worse, so my routine became repeated HEPA vacuuming and damp wiping of the hybrid timber floors. That helped bring the “hostility” of the house down to about a 3/10.

I then noticed the walls themselves seemed to be giving off some kind of smell/gas that I was reacting to, so I encapsulated them with shellac-based paint, which helped a lot. After that, I also started fogging and mopping/wiping more aggressively. That brought the house down to around a 1/10.

The air still doesn’t feel fully clean, so I’ve reintroduced air purifiers. They seem to help only when run on low to medium. If I turn them up too high, they seem to stir up settled contamination and the air feels more hostile again.

At the moment I’m running:

- a Vevor 800 CFM air scrubber and three 300 CFM air purifiers in the large kitchen/dining/lounge area;

- one 225 CFM air purifier in each bedroom.

The domestic purifiers are all Sôlt brand, which is a cheaper Australian brand.

All units are running on low to medium. The domestic units are placed centrally on the floor. The scrubber is against a wall, with the intake facing the middle of the room and the exhaust facing upward.

The air coming directly out of the units feels fresh, but the overall air in the rooms never becomes totally neutral. The PM2.5 meters on the purifiers usually hover between about 5 and 8 µg/m³ and rarely go lower.

I can’t find any obvious dust reservoirs. Most of the rooms are empty, with no furniture or stored items.

Has anyone dealt with this kind of residual mould/dust sensitivity after remediation? Any suggestions for getting the house comfortable enough to live in again?
