Is an air purifier sufficient for preventing dust buildup in my PC, or should I also get more case fans? I heard dust buildup is reduced with more case fans; that makes sense, though I don’t know if that’s true. I was looking at this purifier. Is this good enough, or should I get something else? It’s the 160 square foot one since my room is 150 square feet. https://www.amazon.com/hamilton-beach-04384-eliminator-permenant/dp/b003riubg0

I have a Fractal Design Meshify 2 Compact: https://www.fractal-design.com/products/cases/meshify/meshify-2-compact/white-tg-clear-tint/

It comes with 2 140mm front fans and 1 120 mm rear fan. That means I have space for two 120 or 140 mm top fans and 1 120 mm bottom fan. I can replace the 2 140 mm front fans with 3 120 mm fans as well. What would be the best approach to reduce dust buildup?

Having positive pressure through dust filters can reduce dust build up. It has nothing to do with having more case fans though if you have more exhaust fans than intake you end up with the PC pulling air through every available hole due to negative pressure.

You'd likely need an air purifier rated around 500sq feet to reduce dust for your room size.

I use these in every room and they seem to slightly reduce dust at best.



Air purifiers are only worth buying if you want to breath better not to reduce PC dust keep in mind with all of them you have to change filters every 6-12 months.

No, air purifiers will reduce dust, allergens and pollen in the room, but they won't prevent buildup inside the PC.

I have a good air purifier and I still need to clean my filters and my PC on occasion.

Dust inside a PC is just something you'll have to live with.

(Personally I wouldn't buy anything named Hamilton though....But that's just me maybe..)
Yeah, I guess the only way to know for sure is to try it for a few months and see how it is lol. And damn I didn’t know Hamilton Beach was a bad brand. I was only considering this one since it’s the cheapest air purifier I could find with a reusable filter.

Oh okay I see. So, would it actually be bad to add an extra bottom fan and 2 more top fans then? I suppose the bottom fan would at least help since it’s an extra intake fan.

and I see, why is a 500 square feet air purifier required for a 150 square feet room? I suppose it’s much much better at getting rid of dust even in a smaller room. I’ll look into that air purifier then; I was only looking into this one since it’s the cheapest one I could find with a reusable filter; I don’t know if the filter is actually high-quality though since it’s not a HEPA filter, so I may need to replace it anyway.

Would an air purifier at least help with reducing dust buildup in other parts of my room like my keyboard and stuff I might want to resell in the future like old parts and games? I do have pollen allergies, so I hope the purifier will at least help with that, and better breathing in general would be good too. My Hamilton Beach one is probably a pretty bad air filter since it lacks a HEPA filter, though I’m not sure how to check if a filter is good or bad.

Metro Datavac works great.
Thanks! I’ll buy that and clwan my PC when I need to then.

how often do you need to clean your PC?
Depends on how fast the dust build-up is.

I do it usually 1x in the 6 months.
Edit: Ah you meant that question for @dgianstefani probably ..Ok.

If you have pets you probably have to clean your pc out more often.
Not counting your goldfish. :D

That’s still good to know. I’ll clean it every 6 months as well then too to make sure dust buildup isn’t too bad. Thanks!

An air purifier will help but it would be best to slap some air filters on your intake case fans if you can.

Every time you walk across carpet you stir up some dust and fibers. This is kind of gross but people shed skin cells constantly. If you have pets they shed fur and dander. If you smoke then there's the issue with tar. An air purifier can only cycle the air so many times per hour so it's not perfect.

Don't go for cheapest - look for true hepa/hepa, a large filter (activated carbon is what is needed to remove VOC, and this has an absorbent capacity), small filters are borderline useless since you'll have to replace them several times a year to maintain effectiveness.

Noise is a big one with air purifiers, the filters only need to be large, preferably have a pre filter you can clean, and have a hepa rating. Mine is audible but not too bad.

Purifiers won't really fix dust buildup, that's just a fact of life, since your skin is always ablating. They will help with allergens, general air quality and hygiene though.

You'll save money in long run by buying a purifier with a large and good filter that only needs replacing once every year or so if used daily for an hour or two, mine is rated for 12 months and costs £20.

I'm going to give you a sort of a yes on your question. Because over the years I have ran both a small (and good) air purifier and a very large one in my work room.

These are my findings.

Yes the large one is better than the small one in reducing dust particles in a room faster.

Yes the small one is better than none when you have computer equipment in your room.

You will always have to clean out your rig. The question comes how many times a year that you need to clean out your rig.

In my case, because of my heavy use of my computer, without a air purifier it was every 2 months or less. A lot of dust even with the filters on the rig will be on the components.

With the small air purifier near by, it was 3 to 4 months but usually 3 times a year.

With the Breath Smart (classic) that I have It's at most twice a year and with that its just less than 10 minutes with a compressor. Overall not bad on the dust and well within safety considerations.

You know that dust is a major killer of components so keep your rig clean and good air flow and your rig it will last for years.

That makes sense. I believe my Fractal Design Meshify 2 Compact case comes with front, top, and bottom air filters, so hopefully that’s good enough. I suppose I don’t really need top and bottom air filters since I don’t have intake fans there, but why not since I have them.

oh okay thag makes sense. I’ll look for an actual good air purifier then with a prefilter, a true HEPA filter, and an activated carbon filter. That makes sense that I’d have to replace small filters more. I thought this permanent air filter was actually permanent and would lasy a while, but 20 euros a month for a quality air purifier sounds better for sure. And that’s true, I didn’t consider noise, yet large ones would definitely be better for that.

and I see, so they won’t really help much anyway with dust. Well, at least there will be better air quality and then. Thanks!


Instead of messing around with air filters and purifiers and all that just clean the PC out once every month or two with a Metro Datavac Electric Duster.
Thag makes sense. That’s much more useful, so I’ll buy that and make use of that. Thanks!

On my Cooler Master Cosmos 1000 I went full ghetto and replaced both side panels with 99 cent furnace filters from Menard's. I found a size that fits perfectly plus using them lowered temps inside the case by around 20 degrees F.

That makes sense, so filters have their own issues too. I’ll definitely get that Data Vac blower to clean up my PC. Thanks!

I don’t know if my small purifier is good to be honest, but hopefully it’s good enough to get it down to 3 to 4 months as you said. 2 months would definitely be quite annoying for me to clean. I’ll look into a larger one then to get it down to twice a year and just 10 minutes of cleaning.

right, I’m definitely very scared of dust since I want my rig to last for many years. I’ll be sure to clean it out properly as much as I need to avoid any dust issues.
On my Cooler Master Cosmos 1000 I went full ghetto and replaced both side panels with 99 cent furnace filters from Menard's. I found a size that fits perfectly plus using them lowered temps inside the case by around 20 degrees F.
That’s definitely an interesting solution, and I’m glad to see that it’s helped so much. I’ll look into some of those furnace filters and see if I can find a size that fits my case perfectly as well. Lower temps are always nice as well as less dust. Thanks!

As someone who used to live at home with a lot of dogs, and parents that chain smoked, I would have to clean my system out regularly.

I was recommended these about 10 years or so ago and they work wonders. They are magnetic dust filters you can put on the outside of your case if magnets will stick to it. I want to say they also have kits that use a bit of adhesive to help them stick if your case isn't magnetic.

They do cover normal fan sizes and some filters are made for specific cases. They used to make custom to order filters, but I don't know if they still do.

You used to only be able to order from them directly, from South Africa, but it appears they have broadened their distribution to other online stores.

To clean you only need to run a Swiffer over them or you can use cold water, just make sure they are fully dry before putting them on again.

Air purifiers absolutely help in keeping your gear cleaner. My home is old, built in the 50s so dust is a constant battle. As a result, I have purifiers in every room that run 24/7. Keeping the filters clean is imperative with your purifier. Whether you go with a replaceable filter or the kind you remove and hand wash or vacuum off.
Despite having them on all the time, dust build up will still occur, it's inevitable. The scale will be far lower with a purifier.
In regards to your question about adding an intake to the bottom of your case. That's going to require far more attention. PSU intakes and lower intakes always get gummed up faster than any of the other intakes on my cases If they are filtered (as they should be). Altho a quick vacuum and the exteriors are clean again but...you will find that very fine dust gets through your filters. A data vac is great for most of the easy to get to areas. Then there's the pita to clean dust. It seems to stick to everything via static, especially fan blades. This is the stuff that requires
anti-static brushes to clean off completely. You can get them anywhere. Anti-static paint brushes, makeup brushes, acid brushes etc... there are a variety to choose from.
I despise cleaning my cases. So, I never leave my rigs running, never allow pets in my office and always leave my purifier on high when I'm not in there. Other than quick filter vacs once a month, I generally only need to do deep cleanings every 6-8 months.
GL with your dust war!!!

If you want to avoid dust, you'll want to look up the Air Exchange Rate for the loosest-spec Cleanrooms.

Consumer air cleaners are roughly based off general HVAC AERs, and woefully insufficient for those with MCS/Allergies or long-term computer equipment operation (like a server room, or homelab).

For general dust reduction, you'd be better off with a couple pleated MERV8+ filters in an A-frame arrangement off the back of a box fan. Noisy, but considerably more air exchanges through the filter media than most 'air cleaners'.

Semi-related:
avoid ionizers.
They'll charge the air, and you *WILL* ESD into anything and everything at a lower potential.

Is an air purifier sufficient for preventing dust buildup in my PC, or should I also get more case fans? I heard dust buildup is reduced with more case fans; that makes sense, though I don’t know if that’s true. I was looking at this purifier. Is this good enough, or should I get something else? It’s the 160 square foot one since my room is 150 square feet. https://www.amazon.com/hamilton-beach-04384-eliminator-permenant/dp/b003riubg0
That is a good unit. You will also need to remember that regular vacuuming is also essential for keeping dust out of a particular environment. Nothing is ever perfect, but simple methods will help greatly.

No, air purifiers will reduce dust, allergens and pollen in the room, but they won't prevent buildup inside the PC.
What? If one can reduce that amount of "stuff" floating in a given airspace, then how much of that same "stuff" is pulled through a PC case will naturally be reduced as well. This is simple physic's, math and common sense.

It's whatever you can afford. Lets go with that first. I like to tackle the entire room and not one small area as of course you are also breathing all of that dust as well.

A used Bionaire will cost you around here $25 to $50. New ones cost a lot more. Air filter Cartridges will cost you $10 to $14 each change. But you can clean out the filter with a vacuum cleaner to make them last longer. Or you can make your own filter as well for $1-2 dollars like I do for the smaller units. You can place your smaller unit closer to your working area/ computer and get almost the same results as the larger unit.

A larger unit like my Breath Smart will cost out $400 new. Used $150 and up. Filters can be expensive but you can get generic. Filter cleaning is important and has to be done at least every 2 months as it really picks up the dust in your room/area and you just use a vacuum cleaner for it. Filters cost $50+ for generic $80+ for regular. You can make them last depending on your environment 6 months to a year. I'm in the 8 month range but as stated before I vacuum my filter as needed and that is at minimum 2 months


If you really want to get inventive, here are a lot of videos on the DIY aspect on youtube.


For the record many of these do the job of getting dust out of the air but the deciding factor is the filter itself with all air purifiers/diy

For the Record. One of my successful businesses (before retiring) was in building cleaning and maintenance. I had to know all of this information on what is to be used in HVAC systems and ratings.



There will always be tradeoffs. This information given is opinion only. It is not gospel. It is what works for me.

So in Ending. IMHO

If you do not have the money. You might want to do a Diy project.
If you have some money you can go and buy a small used air purifier.
If you have more money you buy a used large air purifer.

If you have eyeballs of money then you buy new.

Maybe I got lucky but the reason why I said used is that the ones I picked up lasted me 5 or more years before needing repairs that I can do myself. It costed me less than 1 dollar a month I spent on a Bionaire and again your mileage will vary. And yea I would do it again if I had a smaller room or a single bedroom that needed one.

My Breath Smart is virtually a glorified high volume squirrel cage fan, with electronic do dads on it and a HEPA filter, that has a skin that makes it all looks nice. But its air cleaning area is good for over 1000 sf of room and it does the job well.

But over the years 46 years to be exact of seeing and using a box fan with a filter in the back in work shop type of environments... so yea they work too.

LOL, a low end consumer device powerful enough to bring that reality into existence? Theory falls apart when faced with modern manufacturing all too quickly here. Having a button for ionization will allow removing a larger selection of (mostly smoking related) particle sizes.

There are of course conditions where ESD and other hazards to electronics are already exaggerated enough you would do well to avoid multiplying the effect. Again, reality is those particles will rapidly decharge based on the airborne contents of most computer gaming stations (smaller spaces you have been or will be breathing, eating, etc. in).

On my Cooler Master Cosmos 1000 I went full ghetto and replaced both side panels with 99 cent furnace filters from Menard's. I found a size that fits perfectly plus using them lowered temps inside the case by around 20 degrees F.

Pretty bright since they will attract and capture particles moving past and into them while being air permeable enough to allow heat exchange.

Speak for yourself...

Circumstances:
-<1000cubic foot room, 2nd story apt. Riverside, CA

-Surround Air XJ-3800

-(painted) Metal Desk

Took me over a week to figure out that the Air Cleaner's ionizer was the cause of near-constant ESDs to my metal desk, and the occasional crash when inserting USB devices.

I 'got a clue' when earthing the desk INCREASED the intensity and frequency of the ESDs.

Sticking a screwdriver down into the Purifier's exhaust (while unplugged, and the driver's shaft earthed) and disconnecting the power to the Ionizer 100% resolved the ESDing.

So, sorry: You're (mostly) incorrect.

ESD hazards are indeed overblown... But only when ambient humidity is favorable (50% or better) and there are not extenuating factors (HV devices nearby) involved.
Which, to be fair, is the case for most home-users.

Fans moving through air produce a static charge which attracts dust, ahir etc. The only way to keep any electronic free of dust is to have it hermetically sealed with water cooling or very low power fanless devices and using wireless tech on all input and output devices, and have the power plug hermetically sealed on the PSU...
