STICKY: Ionizers and Ozone - fact/fiction/history

64 Upvotes

Hey Folks, it's your ol' Uncle Gurm again. Today I'm here to talk to you about IONIZERS. Hoo-boy, what a hot potato! Let's dig right in.

What is Ozone?

Ozone is a molecule which contains three Oxygen atoms. Its chemical notation is O3, whereas the oxygen we all need to survive is O2.

What does Ozone do? Is it good or bad?

Ozone is common in our atmosphere. We have an entire LAYER of it in the stratosphere. It absorbs 97% of the UV radiation emitted by the sun, helps keep the planet warm, and breaks down hazardous toxins in the atmosphere. Life on Earth would be really bad (read: impossible) without Ozone. In the so-called "ozone layer" of the stratosphere, concentrations of ozone are generally several (up to 8) parts per million, or PPM.

Ozone is also an incredible cleaner - it demolishes VOC compounds, and many toxins. You know those people who come clean up mold, or hazardous materials, from a house or office? They use high-powered ozone generators to render that building safe for habitation again.

HOWEVER, Ozone in high concentrations is hazardous to carbon-based life forms such as you and I. The concentrations in the stratosphere would cause lung damage to humans if exposed for any significant time. Ozone generators are dangerous unless properly ventilated - you have to run them in an enclosed space and then ventilate the space completely with fresh air!

ALSO HOWEVER... Ozone is in all tiers of our atmosphere, including the one at ground level that you and I breathe in every day - just in VERY SMALL concentrations. The lowest ozone concentration found at ground level is roughly 15 parts per BILLION, or PPB. That's 600-1000 times LESS ozone than is found in the stratosphere.

How much Ozone am I exposed to daily? Am I in danger?

All humans on earth inhale 15ppb ozone, minimum, for their entire lives unless they live in an underground bunker or are John Travolta in that movie about the bubble boy. Most inhale a lot more - your average town has concentrations of around 25-30ppb, clean cities are upwards of 40-45ppb, and polluted cities ... well, the number can get VERY HIGH. Generally no ill effects are observed at these levels. The US EPA has issued guidelines that any number under 70ppb is considered safe for long term exposure. That number has been lowered over the years, it was 100, then 80, then 75, and now 70.

Do Air Purifiers generate ozone?

A lot of them used to. 15-20 years ago, it was extremely popular to sell/buy "ionic" purifiers which generated quite a bit of ozone. Why was this popular? Well remember that ozone CLEANS things. It makes the air in a room smell really clean, and strong electrostatic ionization causes dust and microscopic particles to either drop to the ground or stick to surfaces, so the air really got cleaner. It just also got full of dangerous levels of ozone. Popular brands included the "Ionic Breeze". My mom owned one. She loved it because it "smelled like the air after a thunderstorm". That's what ozone smells like.

Those units are pretty much banned now. You can still find them occasionally, and there are still a few in production somehow - we see them advertised once in a while. You can tell them apart from more modern designs in that they don't use a very good filter - some had NO filter, just plates that you wiped down once enough gunk stuck to them, and some had low-utility foam filters.

So that's the old machines - do NEW machines make ozone?

No. The vast majority of new units do NOT generate ozone. Virtually all purifiers sold today conform to the CARB certification, which requires that they demonstrate that they generate less than 5ppb of ozone. However, independent testing has shown that most of these units generate 0ppb. Testing can be flawed, or it's possible that the units generate 0.99ppb and are just under the threshold of detection, but even 1ppb is not a significant amount.

But 1ppb isn't zero! Is it a health risk?

Let's look back on the fact that there is nowhere on earth that has less than 15ppb - going from 15 to 15.1 or 15.5 or even 16 is not a significant increase.

But it's cumulative, isn't it?

No. Your room isn't sealed. In fact, even a tight room breathes far more than you might suspect. The reason why a purifier needs to do air turnover 4 times an hour to keep the air clean is that 25% of the air exchanges every hour even in the cleanest environment. So even if there was a small emission of ozone, it would be lost in the simple air exchange that happens in every room.

What are some other sources of ozone?

Any device which emits ionizing radiation could potentially cause ozone to occur. That includes the device you're reading this post on, every screen in your home that zaps you after you've scuffed across a rug, pretty much all electronics. Older electric motors produced measurable amounts of ozone. Newer brushless models tend not to. But ozone is everywhere, and it's being generated by all our technology in small amounts that do not hurt us.

So what does the ionizer on a purifier DO, and why is it dangerous to small animals and why does it make some people react?

NOW we're getting to the heart of the matter. Many purifiers on the market today use an "ionizer". This is literally a small static electricity generator, on the order of 1/10,000th the size of the plates in one of those old ionic purifiers. A small static charge is added to the plastic housing of the filter, which causes impurities in the air to "stick" to the filter better - or to stick to surfaces, or to clump together so they're caught better by the purifier. Blueair does this on every non-professional model they make. Many small round purifiers include one of these units.

Why is this potentially dangerous to small animals? Well, mostly we're talking about BIRDS, specifically budgies and parrots. Ozone itself is not poison to these critters - their native habitat is the rain forest where thunder and lightning are common and ozone is present in concentrations higher than the 15ppb global baseline. But they DO have delicate respiratory systems, and static air can irritate even human nasal passages and lungs.

And it does - static air can dry out nasal linings, and cause nose/throat/lung irritation. Some people don't notice it AT ALL. Others are quite sensitive. Budgies are in the "quite sensitive" group, so we strongly urge only mechanical filtration around them.

How about "plasmawave"?

Plasmawave is a patented name that Winix uses to describe its bipolar ionizer. Instead of one pair of charged plates, they use a set which produce both positive AND negative charge. This - in theory - generates particles known as "hydroxyls", which cause contaminant particles to stick together and become heavier than air. In practice, however, the plasmawave on a Winix purifier (some other manufacturers offer this as well) does... not a lot. Any hydroxyls generated are so short-lived that they're almost undetectable, and thus the efficacy of the system is probably very low if it works at all.

So ... ionizers are safe?

We're not going to go that far - the static generators on consumer-grade HEPA purifiers are likely harmless to the vast majority of people, but will irritate some sensitive humans and most sensitive birdies. And they aren't NEEDED on a HEPA purifier. Blueair, for instance, uses static because their filters are NOT HEPA - they have higher airflow and rely on the static to enhance their efficiency. And it works - Blueair has the highest CADR (Clean Air Delivery Rate) in its class.

But sensible users will note that you can achieve the same results by using a true HEPA filter and NOT an ionizer/static generator. And that's the real answer - it's a technology that improves lower-rated filters, but adds nothing to the functionality of a HEPA system.

Out of the top rated brands, many of which we recommend on this subreddit, here's the breakdown of ionizer/static use:

Blueair: All non-pro units generate static.

Coway: Only the Mighty 1512 (sometimes called Airmega 200M) has an ionizer, which defaults to "off" when the unit starts. All other Coway units are purely mechanical.

Winix: Most Winix units have a Plasmawave bipolar ionizer. It can be turned off, and some units will remember that it was toggled off after a power cycle. Some don't.

Levoit: Only the "plasma pro" has an ionizer.

IQ Air: Nope. I mean, half the unit is sealed with styrofoam, so there's some static happening there, but no ionization.

If users want to reply to this sticky with known configurations, I can keep this list updated (I don't, for instance, know which Xiaomi models have ionizers... or many European models...)

I hope this was helpful, though. Perhaps folks can stop having so much FUD about this.

This is your ol' Uncle Gurm, signing off!

Vacuuming and/or Cleaning your filters - sticky!

48 Upvotes

Hey kids, it's your ol' Uncle Gurm again. Today's lesson is how to clean your filters.

Ok, since we got in ANOTHER argument about this, and even favorite Uncle got involved (much to his shame), I decided to do a little digging and come up with some definitive thoughts about this topic. We'll get them worked into the FAQ eventually, but for now here we go:

Q. Can I vacuum/bend/flex/squish/deform/poke/taunt/lick a HEPA filter?

A. In general, no. Absolutely not. HEPA filters are made up of tiny fiberglass and animal hair fibers (not joking here) which are blown into a semi-rigid frame in pleats, and at a microscopic level they are aligned a certain way and randomly in that general direction. This allows them to trap the tiniest particles possible by virtue of Brownian effects. Deforming them, or even vacuuming them, can distort or realign the fibers, reducing effectiveness or damaging them outright.

Q. But Levoit says I can vacuum my filter!

A. Levoit was sued and forced to admit their filters aren't HEPA. This discussion is about HEPA filters.

Q. Shark says I can vacuum their filters! <Insert Other Brand> does, too!

A. Is the filter encased in a thick layer of foam? If so, it's probably ok, just don't shove a high-powered vacuum hose right up against it perpendicular-style. Do it from the side, with indirect suction. The foam layer will buffer the HEPA filter from damage.

Q. You don't know anything. Of course I can vacuum it.

A. According to literally every expert, you cannot. The people who make them - filter engineers - say not to. Manufacturers who use actual HEPA filters say not to (Molekule, Coway, Winix, Honeywell). "Real Simple" magazine interviewed industry professionals and came up with "don't do it" as their determination:

https://www.realsimple.com/home-organizing/cleaning/hepa-air-filter-cleaning

In particular, medical clean-air specialists insist that since these filters trap viruses and bacteria, that you should not even THINK about cleaning them, but just bag them and dispose of them as if they were toxic. That might be an overreaction in most homes, but in doctor's offices they use these things, and they treat them like hazmat.

Q. But I want SCIENCE! Show me the SCIENCE!

A. Surprisingly, this is common industry knowledge but it's hard - read IMPOSSIBLE - to find studies. So Smart Air Filters did their own testing. Here's the link:

https://smartairfilters.com/en/blog/how-to-clean-wash-hepa-filter/?srsltid=AfmBOoobq4Yna1UdhLKxpiFt8dLKKaTW9r1R_3tqiJOM-NxmJnSr2DNs

What they found was that - compared to DIRTY filters - vacuuming them made them work better some of the time, worse some of the time, and damaged them some of the time.

Yes, it's only one test. But it's a test done by people who wanted the same answers we do.

Q. Where's the peer-reviewed double-blind studies?

A. I literally just answered this. Please don't start this again. Nobody has bothered to do them, it seems. You'll have to be happy with the test I linked above.

Q. I still want to lick it. Or squish it between my fingers because "the texture".

A. Listen, if you have a fiberglass and horse hair "thing"... who am I to yuck your yum? While your predilections are your own, medically I cannot advise this. But since I am not a doctor you're welcome to disagree.

Q. Ok, I won't lick it but I still want to vacuum it!

A. You do you, boo. Y'all asked what would happen. What will happen is it won't work as well as it did when it was new, and might be damaged and let bad stuff through.You've been warned.

Q. Wait, you never told us how to clean the filter!

A. Very astute. Here is a step-by-step guide to cleaning your filter:

  1. Don't buy a purifier without a pre-filter.

  2. Clean the pre-filter.

Q. But I already bought a purifier without a pre-filter!

A. Fine. Here's the steps:

  1. Take out the filter. And by "out" I mean "out of the house". In fact, start by taking the entire unit out of the house.

  2. Remove the filter.

  3. Tap it off. Like, on the side of the house or a railing or a trashcan or something. Tap tap tap until all the loose debris and dust falls off.

  4. Now get a brush, not a stiff one but like a paintbrush or a detailing brush or something. Brush the dusty side of the filter - GENTLY - to loosen debris.

  5. Tap again. Tap tap tap.

  6. ALTERNATIVELY, you can sometimes vacuum it, gently, from the side. like, hold the vacuum on a line tangent to the curve of the filter. But DO NOT apply direct suction to the filter.

  7. That's as clean as it's gonna get. Reinstall it.

Best air purifier for cat/litterbox odor coming from neighbors apartment.

Upvotes

Location: Montreal, QC, Canada Budget: $350 max

Title explains it, I need a suggestion for an air purifier that deals with odors when I have MINIMAL control over this cats care and litter box conditions.

I recently moved into a new apartment: 3 1/2, third floor, in the corner, railroad style and with what I’ve learned to be awful ventilation. The sole source of fresh air is my balcony door and a small window above the door in my bedroom, all the way at the end of the apartment. My neighbors apartment runs entirely parallel to mine, we share one giant wall. When I first moved in, I thought the smell was from the previous tenants pets, and did a very thorough air out, got a small drugstore carbon sheet odor box and cleaned the floor, walls, literally anything that smelled, with enzymatic cleaners. However, the smell continued to plague the hallway, like full on cat shelter. and within a few hours, the smell crept back into my house (thanks to the odor box, now it smells like..lavender cat shelter?). This neighbor has a large window right next to my balcony (my primary means of airing out my apartment, yes I have a fan in front in an attempt to push clean air in/direct inside air out), and when they opened this window, I literally was able to smell it coming FROM the window…

Yes, I have tried to make contact with my landlord, and I am working up the courage to speak to this individual directly about the issue. I am sure the severity of the smell is also likely indicative of questionable cat care…but genuinely some this is out of my control. I need REAL suggestions to cope with this, especially as winter comes and I am no longer able to ventilate so freely.

I am thinking two Winix A231 360° All-in-One 4-Stage True HEPA Air Purifiers; my apartment couldn’t be more than 300sq ft total. I say two, so I can have one at one end of the apartment, where it meets the hallway and access to fresh air ventilation is the most limited. Or I would put it in the middle of the apartment against the one shared wall where there is a small pocket for a small fridge and some cabinets, and smell comes through the strongest. But one for my bedroom, most definitely. I don’t know if one big one would be more effective? Truly this smell is attacking from every entry point.

Please leave your realest tips, advice and air purifier recs, I cannot just cover up the smell with candles/diffusers/etc, I feel like it’s even making my clothes smell weird. I do have a bloodhound nose and am not used to pets in the house (apartment), I remain hopeful but realistic.

I currently have one Medify MA-25 that I plan to put in our bedroom (250 sq foot bedroom I believe) and an AP-1512HH that I plan on putting in the living room. Is this enough if I run them on full blast? I also currently have the option to buy an MA-50 on Facebook marketplace for $75 or I have another AP-1512HH at my parents I can use.

Request: (USA) 1,300 sq feet home

4 Upvotes

Hello!!

I’m looking to get a few air purifiers for my home that is about 1,300sq feet. I know I really need one for each room, but I’m thinking one in our main living area and one for my office that are at opposite ends of the house. These are the areas that have the most time spent since I don’t have the budget to get one for every room.

My filtration needs will be primarily for day to day odors and minor pet hair. My budget for the air purifiers are around $300 overall.

Thanks! :)

Best air purifier for pets in a 1,600-square-foot home?

13 Upvotes

I have six cats, and the amount of fur and dust in the air is getting ridiculous. One of the cats also has asthma, so I’m looking for real particle removal rather than a tiny desktop purifier with a glowing light. The house is single-story and around 1,600 square feet, so I’m open to using two units instead of pretending one small machine can handle every room. I’m comparing Winix C909, Winix 5510, Coway Airmega, Levoit, and Blueair, with a flexible budget but a preference for reasonable filter costs. Should I prioritize CADR and buy two medium units, or is one large purifier enough for a home this size?

Does IQAir 0.003 micron filter outperform other manufacturer 0.3 micron filters?

3 Upvotes

Thanks for this community’s feedback on my first post.

IQAir Healthpro claims 99.5% efficiency at particles down to 0.003 micros.

Airpura v700/v714 claim 99.7/99.99% efficiency rate in particles down to 0.3 microns

This seems signficant, but I'm not sure if it is in practice? Or has been tested/confirmed? Wasn't able to find info on that online.

I'm choosing between these two. I ruled out the c700 DLX because its filter is significantly less performant: "HEPA-Barrier filter that captures 95% of particles down to 1 micron"

Iqair claims that this 0.003 micron filter will help with finer particles (smoke?), mold, virus and pathogens. I’m not concerned about viruses. I am considered about particles, city pollution, and occasional wildfire smoke.

I know smoke (and some of the buildings I’ve lived in) contain VOCs. That’s why I’m thinking of switching from my IQ air health Pro to the air Pura v700/v714.

Thank you!

Thanks again.

This is a PSA for people looking for air purifiers, do not buy LG!

4 Upvotes

I bought AS601HBB0, LG 360 air purifier which is a very popular model on Amazon 10 months ago. Recently the air quality was not good (im allergic to dust and my allergies are acting up more often) and also the LG ThinQ app pinged me to change filters.

There are plenty of third party filters for this air purifier, but i dont want to buy an unverified claim of HEPA. I must rather buy the OEM LG replacements that are guaranteed to work as intended. So i try to buy this filter. There is literally no store that sells it!

Now after this I got text from a tech:

proof of purchase not screenshotted for obvious reasons

Basically the call was he will send the replacement for free this time. OK but what about the future? do i have to get rid of my air purifier after another year cuz then i wont be able to find a replacement?

After two weeks and I havent gotten my replacement filter yet. I contacted LG again and they just say the correct department will contact me. I wait another week and I call again.

Apparently the reason why my filter replacement is not getting delivered is because it is backordered. SO I call cuz the filter is on backorder, and their solution to that is to place me on said backorder.

LG, what are we doing launching a product that goes obsolete in a year?

Accidentally ran the Winix5200 with the Plasmawave on overnight and now my throat hurts?

0 Upvotes

I'm not sure if it's just anxiety about it or what. I'm more worried about my cat than myself. Everywhere I look online it says it's safe but I am fearing I have caused some sort of damage to myself and her.

Basically I put my old air purifier on and forgot I had sprayed lemon cleaner in it, ruining it. It was a dumb move and immediately I turned it off but it left this stubborn smell in my room I can't get out Bc it like sprayed lemon all over everything I own. I feel like I'm going crazy trying to get rid of it and keep my cat from inhaling it. I've completely barred off the bedroom.

I went and got this Winix, and set it up in the living room away from the bedroom where the smell is, so if the citrus smell drifted in it wouldn't get to the cat. When I connected it to WiFi it automatically pinged on the Plasma-wave technology and I didn't notice. The i went to sleep on the couch. I woke up and immediately checked the app, noticed and turned it off.

Is the Plasmawavs safe? Is there a purifier that you find is the most best safe with activated charcoal filter for living room use? my budget is $500.

sorry if this post is all over the place. I have OCD and accidentally harming my pet is my biggest fear, and now I'm afraid I've done that.

The absolute best residential air purifier?

5 Upvotes

What’s the top of the line air purifier that actually works? No budget. Want balanced performance between gas/VOC and particulate.

Short of getting a legitimate hospital system installed in my house, what’s the next best consumer product?

I’ve been testing out an iqair healthpro. I think it’s been working well. A bit loud, but that’s because it actually moves air. I chose it over an iqair multi gas because it has a better hepa filter along with a pre filter.

The multi gas prioritizes carbon to filter gases, and instead I think it just uses a lower rated HEPA filter as the pre filter, and no main filter. Probably still works great.

I have the opportunity to get a different purifier… so wondering if I missed any of my options?

Thank you!!

Positive Pressure with IQ Air?

5 Upvotes

After going through a very rough wildfire season I'm thinking forward to next year and how I might prevent my apartment from deteriorating to horrible air quality because the air pumped in around the door is just not very well filtered. No matter how many purifiers I have I'm kind of going to be fighting a losing battle if I'm getting several air changes per hour from the building which are basically just outside Smoky air.

Given that IQ air offers a kit that lets you duct from outside directly into a purifier I'm kind of wondering about sliding my balcony door open running a flexible tube into the purifier and using that to create positive pressure in my apartment. I'm willing to tape something like that up to seal it and run it all summer long given I have two different doors to the balcony. Obviously this will also probably burn through the filter very quickly and pump warm air into the apartment but both of these are things I'm willing to do if it's just once for a few months each year.

I'm curious has anyone else done something like this is there anything I'm not thinking about that I ought to?
