If you're in an area that is suffering from wildfire polluted air, I just saw this on Twitter:

Bonus:

Here's a site I found that can tell you how to make these:

Edit: There have been some extra pointers (about open sources of water in the home, and I believe some other things) in the reblogs, so I highly recommend taking a look at the notes of this post!

Also: Cloth masks are NOT sufficient. Use KN95s or N95s!

I see a lot of people sharing recommendations for making this kind of DIY air filtration system. Since I have been using one of these for several years now, I have some practical comments and caveats:

Their useful lifespan is relatively short. A set of filters is good for maybe 60 to 90 days before it becomes so soiled as to be counterproductive, probably less if you have furry pets.

What the filters pull out of the air is deposited on their surface. You'll want to be careful not to touch the filters and keep kids and pets away from them. If possible, you should also put the unit on some stand or surface you can easily clean.

Removing and replacing the filters is nasty. The outer layers of the filters get filthy, and removing the filters involves using a utility knife to slash the tape holding the thing together, which will dislodge big clouds of crap. This needs to be done outside if at all possible. You'll want to wear a respirator and disposable gloves, and old clothes you can immediately launder (or bag and dispose).

You'll need to clean the box fan itself when changing filters. You'll want a can of compressed air to blow dust out of the fan motor, and should clean the blades, grilles, and frame as best you can before replacing the filters.

High PFR furnace filters aren't cheap. At a typical big box store, two high-PFR filters of adequate size will cost you at least $35 to $40 USD. You can bring down the per-filter cost by ordering in bulk online, but that costs more upfront.

These units may not be practical for physically disabled people. If the prospect of picking up and (gingerly) carrying the complete unit is physically daunting, if you have limited fine motor skills, or if you have no way to carry the unit outside to change the filters, this is probably not a good option.

If you need a short-term air filtration solution, such as when there's a lot of wildfire ash in the air, these kinds of filters are relatively cheap and work well if you do a reasonably conscientious job of assembling them and changing soiled filters. However, over longer periods, their cost advantage relative to a HEPA filter air purifier begins to erode because the filters are more expensive and shorter-lived.

A HEPA filter air purifier costs significantly more upfront, and where the air quality is bad, they may be in short supply. However, they're much easier, and usually cheaper, to maintain. Generally, they have a "pre-filter" to catch dust and lint, reducing the load on the HEPA filter(s) so that the latter's useful life is close to a year. (The pre-filter needs to be changed about every three months.) Furthermore, the filters are internal, so you aren't likely to touch them or dislodge their contents except when changing filters, which usually involves just popping them out into a plastic garbage bag and wiping down the interior with a microfiber cloth before replacing them. That can still be a little gross, but it's nothing like the filth and effort of having to gingerly carry the complete unit outside and tearing it apart.

Life update:

So my life has been very hectic, and what was supposed to be a transition to me living in a new apartment and getting started on commissions has been put on hold because just found out the damaged popcorn ceiling has Asbestos that I may have been exposed to.

For those of you waiting for more art on my part, I will need some more time to sort things out.

Details and venting under the cut. If anyone has advice I will take it.

So yeah, I got a nice apartment that I've not fully moved into because getting furniture into the space has been a trial. But now I don't feel safe at all to fully move in and sleep there knowing that the ceiling contains 6 percent of Chrysotile Asbestos, which wouldn't be complete issue if it was properly sealed and non damaged, but in the kitchen that isn't the case, as when I go into the apartment I noticed that there was a damaged and cracked patch of it on the ceiling. Having heard that popcorn ceiling could contain Asbestos I contacted my landlord on the matter. He sent over some local health inspector consultants to take a sample of the spot. Unfortunately, as I later learned, these people were as familiar with dealing with Asbestos, and their extraction method did a number of things wrong: Mainly they did not where protective masks (opting instead to hold their breath), they did not properly wet the extraction area (which I later learned is what professionals do to avoid kicking up Asbestos), and finally they vacuumed the debris with what I suspect was a vacuum without a proper filter (HEPA filters are what professionals use and talking with this inspector he didn't seem aware that there was a specific filter for treating Asbestos and double checking the type of vacuum they used, that model cannot have HEPA filter installed). So I am very much fearful that given I was present when they were doing this, and because there was damage present to begin with, that I have been exposed and breathed in this toxic material. Additionally, trying to negotiate with my landlord to get the air quality of the apartment tested, filtered and the ceiling encapsulated by a QUALIFIED Abatement professional, is proving to be a bit difficult as be believes (talking to the initial albeit incompetent investigators) that testing air quality and filters isn't needed. I've at least convinced him that he need to contact an actual Asbestos Abatement contractor to repair the ceiling and clear the apartment of any lingering contaminates, but ultimately what happens will be up to him. As for me, I at least have people I've been staying with in the mean time but I cannot stay with them forever, and my things are now moved into that apartment and the prospect of either leaving them there or having to move everything out again is giving me such anxiety and dread. I'm not sure what to do if the landlord doesn't proceed as I would like, if I should take legal action or not. Stuffs been so fudged. And on top of all that, a coworker of mine tested positive for Covid and came to work anyway without a mask on. I CANNOT GET SICK NOW ON TOP OF EVERYTHING!?

If anyone has any advice for me in this situation, I would appreciate it.

I just want a place that's clean and stress free so I can make art for a living, is that so much to ask?

The rising inflation has affected many people. The gas prices off the roof. I am a stay-at-home mom unable to work as I am diagnosed with scoliosis of dorsal spine. I already had the first surgery and the doctors don’t recommend for the second surgery. I was suggested epidural injection once a month to which I said NO!! I was given this injection during my daughter’s birth and the experience was horrible.

I was bored sitting at home and was going through google to find what is it that I could do and earn money from home. I tried my hands on building websites, doing surveys, websites that mentioned “YOU CAN EARN SO MANY $$ FROM HOME”. All efforts turned out to be a failure for me. I gave up and didn’t want to try again. My husband was working so didn’t feel the pinch for money that much. Focused on my daughter and life went on. Can’t believe my little girl will turn 13 soon.

In 2022, my husband got retired on medical grounds as he started having issues standing, sitting or walking too much. And now he is diagnosed too with lower back pain. Lately we have been facing financial problems because of regular doctor visits and medication. So once again I tried researching what I can do to get some extra income.

I found a web developer and asked him to create an affiliate blog for me. My niche might not be that challenging but I wanted to start somewhere and soon too. My niche is about wireless upright vacuums and robotic vacuums. The vacuums listed in my blog aren’t that much but you can get a lot of information on robotic vacuums and other wireless vacuums.

Do check my website to learn more.

Efficiency vs. Effectiveness - They are Not the Same Over the past 3+ years there has been a sharp rise in interest related to indoor air cleaners. I have consistently seen confusion over the terms efficiency and effectiveness. This thread is about the difference. 1/

Richard Corsi, PhD, PE (Texas) on Twitter

A helpful & clear explanation! Some excerpts:

As an example, consider an air cleaner that removes close to 100% of particles that enters it, but that only has 1 cubic feet per minute (cfm) of air passing through it.    4/ 

In this example, the air cleaner has a Clean Air Delivery Rate (CADR) of only 1 cfm.  In a typical K-12 classroom (say, 700 square feet with 9 ft ceiling height) this would yield an equivalent of only about 0.01 additional air changes per hour.    6/ 

So, 100% “efficient” may do very little to clean the air if the air flow rate through the device is small.  This was the case for many quiet and non-filter-based air cleaners that were marketed in the 1990s and 2000s.     7/ 

On the other hand, it is possible to have a particle removal efficiency of, say, only 50%, e.g., only half of the particles (or particle mass) that enter the device are actually captured by the device, but to have that air cleaner be quite effective.  What?   9/ 

Imagine a device that is only 50% effective at removing aerosol particles from indoor air (fraction removal efficiency = 0.5).  Now, if the air flow rate though that device is 800 cfm it will have a CADR = 400 cfm (800 x 0.5).    10/

This is greater than most off-the-shelf HEPA air cleaners on the market and far greater than many other air cleaners.  In this case, for the classroom described above the air cleaner would yield an equivalent of about 3.8 additional air changes per hour.       11/ 

This is why the Clean Air Delivery Rate (CADR) is a much better metric than filter removal efficiency when comparing air cleaners.     12/

Keeping Air Pure in Your Home, what is a HEPA Filter?

Do you like pure air at home? I’m sure the answer was yes! With our world rapidly changing with businesses thriving from homes and online learning, there has been a lot of activity going on within our abodes for the past three years. With that being considered, you want to ensure that you are breathing in the best air. Air purifiers work hard at reducing allergens and providing more comfortability in your space.

When used correctly, the air purifier can additionally, help at minimizing airborne contaminants that may include viruses in a home or closed space. Although extremely helpful, a portable air purifier will not purify the air 100%. Therefore, to ensure to it performs at its best abilities, it should be produced with a HEPA filter which is proven to remove up to 99.97% of airborne particles according to the EPA.

HEPA filters are tested to use air particles that are only 0.3 microns! This is the most complex size for a HEPA filter to pick up. According to research done by NASA, HEPA filters are much more capable of catching smaller-sized particles that can be just as small as the size of viruses.

The Functions of a HEPA Filter and How it Works

A HEPA filter is not your typical air filter that you would install into your home. These filters are much more intricate as they are mechanical air filters that are considerably thick to ensure particles are captured. The mechanical pleats create a mat of fibers that are arranged at random. The dense, random arrangement of fibers in the HEPA filter assist in catching a range of particle sizes. As air flows through the air filter, they are caught by three mechanisms which include: interception, impaction, and diffusion.

Diffusion takes place in a HEPA filter when the gas molecules are less than 0.1 microns combine and are prevented from passing through the filter. This delay will then assist in the next two mechanisms to transpire for those smaller more difficult particles to catch. Interception involves particles moving up and down the air stick to a fiber. Lastly, impaction takes place when the larger air particles are embedded directly into the fibers.

 

Why You Need an Air Purifier with a HEPA Filter in Your Home!
