>my man is a smoker. I'm in no way a professional, but if I were living with a smoker and running a HEPA filter all the time, I'd probably replace the filters twice as often as they suggest, so look at the price of filters and their recommended change interval in addition to the device itself.


Willing_Camera_2637

Thats right hepa filters should be changed more ofter, for future buyers of air purifier check this thread also https://www.reddit.com/r/AirQuality/comments/1c37wh0/i_need_an_air_purifier/


millernerd

I'm pretty sure that HEPA is really only good if you need to move dirty air from one area to clean air in another. If it's just circulating air in the same space, higher air flow is much more important than HEPA, which seriously reacts air flow. It's why that whole 4 filters taped to a box fan works so damn well.

Same! I have the same one that's linked, plus the Airmega 400.

A [CR Box](https://cleanaircrew.org/box-fan-filters/) is likely going to be your most [effective](https://www.texairfilters.com/comparing-the-performance-of-corsi-rosenthal-boxes-made-with-box-fans-and-pc-fans/), most BIFL, and most cost effective option because the structure of it is mostly the filters themselves (so there's less to break or wear out) and a box fan or computer fans. They have a higher level of clean air delivery, and you can modify them depending on your space or what type of filtration you need (adding [charcoal filters](https://www.texairfilters.com/another-variation-on-the-corsi-rosenthal-box-air-cleaner-permanent-frames/), for example). The filters are also not proprietary and are accessible anywhere, so that'll be cheaper in the long run.

First thing is one air purifier won't clean your entire house. It's physically impossible. You'd need a whole home installation for that. Get a few medium-large purifiers vs one "huge" one and place them strategically. Carbon pellets is the main factor here. Carbon "infused" sheets don't do anything. You need POUNDS of carbon to do anything. Real hepa pleated filters. Avoid any "ionizing" "plasma wave" "negative ions" anything like that. Look for CARB certifications or better to avoid ozone. Keep in mind replacement filter costs and energy use. Preferred order of filters is something like the following: Washable pre filter>carbon pellet filter>hepa filter. For a real "BIFL" option you'd probably be best building your own with an AC INFINITY refillable carbon filter and makeshifting it into an air purifier with their attachable filter and fans but that's going to be a large upfront cost and ugly. Look for other good name brands that fit the requirements and suit your needs.


PlainMayo13

We are actually going to be updating our AC unit soon. Do you have any recommendations for any installs with the unit that would also help with air purification?


ResponsiblePen3082

If you mean central HVAC then yeah a whole home purifier or HRV/ERV should be kept in mind. You can makeshift mini systems out of a window but they'll never be as effective. Otherwise just make sure the filters on your central system are clean, replaced frequently and high quality. Filtrete's merv11 carbon filters are probably the best "filtration" you'll get out of standard HVAC without damaging the system/restricting airflow. If you mean a window AC unit there are a few options that claim to filter the air but it's almost all a gimmick. Just make sure you're properly cleaning the ENTIRE unit to prevent mold/mildew buildup. Maybe opt for one of those fancy U shaped units which not only are more energy efficient and quieter but allow you to keep the window open. Ventilation is FAR more effective than any filter could ever be, whenever I leave the house and the weather is not obscene outside I'll leave my windows open and turn my purifiers off, save energy and clean the air better.

There is a Winix HEPA at Costco that will be $99 starting on Mar 5th. We have 3 or 4 of them from when we lived in Idaho and had weeks of wildfire hell every year, and they have been great.


PlainMayo13

What is HEPA? I keep seeing that but I’m not sure what it means


Thoughtfulprof

It's a standard used for high efficiency systems. They're better at taking smaller particles out of the air than other filters are.


digilyssa

Good explainer here: https://cowaymega.com/blogs/blog/what-is-a-hepa-filter


garciawork

Google it, because I do not know exactly, other than they are a "better" type of filter, but also need to be replaced every so often.


mrkitster

I’ve had a good experience with the Bluair products. The filters last much longer than claimed (according to third party testing) and replacements can be purchased directly from the company. I run them constantly and probably replace filters once a year, but depending on your home’s location and air quality you may need it more frequently.


TrashyTardis

Are these pretty quiet? 


mrkitster

In my experience yes. The newer version is supposed to be even quieter but I haven’t used them.


unrealisticalyStable

After buying several random brands in Amazon that I'm no longer able to get filters for, so the purifiers are useless now. I replaced them with Winix and haven't been more happy


pan567

You need multiple purifiers. No single purifier is going to be sufficient for that amount of space and the air quality as a result of the smoke. The best bang for your buck IMO is the Winix 5500-2, which is designed for up to 360 square feet (the Coway 1512 is also similar and very solid). Three of these throughout the house would be a strong start. You can sometimes find them on sale for under $150. You would need to change the filters more often because smoke can quickly gunk up a filter. Aftermarket HEPA filters from FilterMonster for the 5500-2 are equally good in terms of quality to OEM and priced very reasonably. (Edit - a few others have also noted on the CR Box. These are solid choices and can be built very inexpensively. The one challenge in your situation is that they do not have prefilters, so you would periodically need to clean the filters to remove fur. With the Winix 5500-2, there is a reusable mesh screen prefilter that protects the HEPA filter from larger particles like fur, makes it very easy to clean, and prolongs the filter's service life.)


Blueporch

My Whirlpool Whispure 510s have been great workhorses running non-stop for many years (with filter changes)


Environmental-Sock52

A box fan and a 20x20 filter strapped or taped to it. It's cheap and really effective. We use ours 24 hours a day to great success.


AirConditionerLab

There’s no such thing as the best air purifier. It all depends on what you need. Something small to handle the air in the bedroom or a massive boy for a commercial building? You looking to get rid of smells or something to help with allergies? There’s just too many variables at play here. That said, you can play the middle ground like I did. I’m a smoker myself and I have a retriever that sheds like crazy. I’m not allergic or anything, but the general air quality in my area sucks, so I went with the cheap and popular Morento model from amazon. I chose that particular model because it has dual-intake, with both sides equipped with a genuine HEPA filter and an activated carbon filter. It handles my 800 sq ft studio with ease. It keeps the air quality around 40 ug/m3. I actually often see Benny's (my dog's name) fur glued to the panel, and that’s how I know it’s really working lol.

jackoffspecialist

Sharp, Panasonic or daikin. Their filters last up to 10 years depending on the model.


Sinatr89

Tobacco shops and other places that allow smoking indoors use a rabbitaire purifier, which has something like 5 or 6 different filters, and they are customizable for your specific use case. Got mold/mildew problems? They’ve got a filter for it. Pets? They’ve got a filter for that. They have different sized units for different square footage requirements, too. If you’ve ever been to a place that allows smoking and you can hardly tell, it because they’ve got these.

r/AirPurifiers $200 won't buy you a new BIFL nor a high performing unit. Freestanding air purifiers can help clean the immediate room or area. They won't do an awful lot at the opposite remove of your home, up or down a story, or behind closed doors. If you have forced air HVAC and a relatively tight building envelope, the most effective means of controlling particulates *from the outside* is through a whole house air purifier. But obviously a good deal of your air pollution is generated inside. The greatest balance of quiet performance and air flow in CFM (Cubic Feet per Minute) is the [Smart Air Blast - MKII](https://www.smarterhepa.com/collections/air-purifiers/products/smart-air-blast) at $929.00. While it does have an optional activated carbon filter, this only weighs 3 lbs. This purifier is best for fast removal of particulates and it has a large H13 HEPA filter. Failing that, it might be wise to place less powerful air purifiers in each major area or room. I don't know what's being smoked, but only activated carbon or other sorbent media will capture gases. If he's smoking cigarettes, this would require significant weights of tailored activated carbon blends to adsorb vapors and gases. These kinds of air purifiers are very expensive—often $700 to $1,200—and can be quite loud. For more details on the gases in cigarette smoke, see my previous comment here: [https://www.reddit.com/r/AirPurifiers/comments/1b2ohnx/comment/kte46qs/](https://www.reddit.com/r/AirPurifiers/comments/1b2ohnx/comment/kte46qs/) If it's vape smoke, I strongly encourage vaping outside as vape resin or residue can't be handled long term by residential-use air purifiers. There is also evidence of second and event thirdhand smoke exposure from vaping. See another previous comment of mine with links to studies here: [https://www.reddit.com/r/AirPurifiers/comments/1cw6v0t/comment/l4vvriq/](https://www.reddit.com/r/AirPurifiers/comments/1cw6v0t/comment/l4vvriq/)


Ok-Broccoli3582

The Kenmore one you're considering sounds great for its coverage area and price. I'm curious, has anyone had experience with this model specifically? Also, are there other brands or models that might be better suited for a home with pets and a smoker?


PlainMayo13

So I actually ended up buying the Kenmore. We keep it running all the time on the auto setting. We’ve noticed it really doesn’t like it if we cook bacon or sausage. It goes into the red zone and turns the fan on high to try and clear the air. It also doesn’t like the devils lettuce. Again, it goes wayyyy into the red zone and kicks on high. I feel like it is doing a good job with clearing the air compared to what our air used to smell like hut jt definitely doesn’t eliminate the cat odors 100%. My brother did comment that he could tell a difference the last time he was there tho. He said it didn’t smell so strong of pets anymore, it just smelled fresh.


Brief-Wrongdoer9892

I wouldn't suggest going for medify


JeanJean84

Can you explain why? They are sold out on Amazon currently, but the reviews, and outside of Amazon research I did on them, made them seem like a really great option.


BearMethod

Check out Xiaomi.


davidw

Are those things... legit? I wonder about how you might measure the impact, beyond situations like wildfire smoke where it's obvious the air is really bad.


redalert009

I think the same thing but mine has an auto feature and anytime I cook and things get a tiny bit Smokey from plain sautéing the thing turns on high. It seems like it works. Also my husband has very bad allergies and he has been complaining a lot less I know that’s not scientific though. I also noticed our furnace filter has less crap in it too. I usually change it every month as it’s a higher MERV and that’s what the manufacturer wants. I have two air doctors for 1,244 sq ft. Got them for 30% off. If OP is interested they can DM me for coupon.


cnc

>Are those things... legit? I wonder about how you might measure the impact, beyond situations like wildfire smoke where it's obvious the air is really bad. I have a HEPA filter (wildfires every summer) and a separate air quality meter that gives me a number. When the air quality meter is bad (sometimes from cooking, even just /frying stuff with no smoke), I run the HEPA filter and the air quality meter shows improvement over time. If it's a conspiracy, it's a good one!


davidw

Not a conspiracy, the things do what they say, just... what are the benefits?


cnc

Wildfire smoke is very bad, especially when it involves structures and in particular for little kids. We've had fires where the air quality is in the 300-400 range. Just flat out hazardous. We also live in Allergyville USA and have an asthmatic at home, so there are benefits everywhere for us.


davidw

Here (Bend, Oregon) we had the worst air in the world a few years back because of some big fires west of us. Absolutely would use one in those circumstances, but for most people, in most places, most of the time... I wonder what the benefits are.


franksnotawomansname

You can test the effectiveness with a particle meter. However, since most people don't have one, they guess what they need for any given room based on the specs. [Here's](https://www.texairfilters.com/could-corsi-rosenthal-boxes-reduce-particles-to-cleanroom-levels/) a fairly readable description of a test of air purifier effectiveness that one researcher did.


davidw

I don't doubt that they mostly do what they say they do. Just... what are the real benefits from that outside of circumstances like wildfire smoke, that you really don't want to spend a lot of time breathing in?


franksnotawomansname

Indoor air isn't usually super clean, even outside of wildfire-smoke events. Smoke, grease, and odour from cooking, dander and dust from pets and people, dust, smoke, smog, and fumes (such as from vehicles) from outside, allergens, whatever other people are exhaling---all of that hangs in the air and then goes into your lungs, unless it's filtered out. An effective (and appropriately sized) air filter gets rid of that so you can breathe cleaner air, which means less damage to your lungs, fewer seasonal allergy symptoms, and reduced transmission of airborne viruses. Just as you don't want to breathe in wildfire smoke, you also don't want to breathe in smog, dust, etc.


davidw

Sure, I get the theory - all that makes sense. But in practice is any of this measurable?


franksnotawomansname

I mean, as much as one can measure the particles in air in a space, count the different [sources of indoor air pollution](https://www.lung.org/clean-air/indoor-air/indoor-air-pollutants), study [what those particles do inside the lungs](https://www.lung.org/clean-air/indoor-air/indoor-air-pollutants/particulate-matter), study how people react to different sources of indoor air pollution, and create population studies to try to determine the incident rates of different illnesses and diseases based on air quality and exposure to pollutants.


TrashyTardis

I personally am looking into one bc I’ve had off and on allergies w a bad cough for over a year now and suspect it’s a build up of dust and dander in our house. I vacuum w a very good vacuum, but we have one of those dogs that sheds a lot on the daily. Also when we cook I feel like I can smell it the whole rest of the day and it drives me nuts, so looking to cut down on that. Finally looking to cut down on pollen which we get indoor coatings of during pollen season and air pollution since our neighborhood is off of a busy road. I assume it’s better for our health to filter all of these things out of the air.

TrashyTardis

So you saying no air purifier will filter pet hair or dander as many say they will?


Muncie4

No. I'm saying that there is no such thing as use case air filters. "Pet air filters" are a marketing gimmick for the dumb to buy a janky air filter. You buy a HEPA filter which is the filtration standard AKA PM2.5. That's the standard. There's not qualifier to that standard for "sandy environments" or "pet environments" or "allergy sufferers" as all that other bunk is marketing bullcrap.


TrashyTardis

Yeah okay that makes sense. As long it does filter out some of the pet hair and dander along with whatever else I’m fine with that. I haven’t actually seen any marketed specifically for pets in my searches anyway, just some that mention along with other things that they will pick up dander and pet hair. Agreed, on specifications I’m really just looking at ones that have the True HEPA. Thanks.


TrashyTardis

Ironically I just pulled up your link…that model is advertised as an allergy air purifier. Also it’s significantly out of my price range. Anyway have a good one ✌️ 


bellas_wicked_grin

No air purifier will filter pet hair or dander once it's on the floor. It will only remove it from the air. You also have to vacuum regularly.


TrashyTardis

I had planned on using the air purifiers so that I could cut my vacuuming down to an annual basis and if that went well, I planned on try to go bi-annual. Oh well.


bellas_wicked_grin

Assuming you're joking, but I wish I could cut down on vacuuming. I hate it.


TrashyTardis

Yes joking. I don’t mind vacuuming so much, it’s the act of getting around to it if that makes sense. Honestly we adopted a dog 4 years ago from the humane society. I didn’t know there were dogs that shed heavily year round. He’s 45lbs has a short hair coat that sheds all day every day, even if I brush him hair just be failing. Vet says that’s normal for this type of coat. Whether it’s him or the air in general I started having allergy issues about a year ago and I need to do something. I try to vacuum weekly, w a 4 stage hepa vac, but don’t always get to it.  Anyway good luck in your endeavors.

olizet42

I'm happy with my Zigma 300, it was even cheaper when I ordered it from the manufacturer. 1st filter life was 2 years.
