Good to know and I just may give some thought into building it. I have plenty of time as the air here is keeping us inside, currently running at 200 ug/m3.

Or you can buy one at a building store for around the same price. It might even have better filters and look nicer

My Honeywell HEPA certified in-home air filter cost approximately $120.

I tend to agree - purchasing may be the better option. However, I suspect they're hard to find on local shelves at the moment.

I have a 4" thick air filter on my A/C, it works great, but they are about $45.00 each.

Yes for a while they were out of stock. That was my motive for building a DIY alternative. Looks like there are a few at bestbuy for now.

I have a $700 dyson tower with a hepa/charcoal filter & I'd take this DIY purifier over it. Dyson is nice for reading the pollution levels & looking nice though.

It depends which filters one would go with the DIY purifier. The ones I use are MPR 1900/MERV 13 which is hospital grade.

Certainly a store bought air purifier with replaceable filters would be a lot more convenient and aesthetically pleasing.

It's a good idea and thanks for sharing. Wish we had data to make a performance comparison. I suspect your filter also moves/filters a lot more air through it. Very possible it's much more effective than my Honeywell filter.

Do you mean a regular air purifier?

We have one similar to this.

I have seen tests done on this before. It does work.

Here is one I just found.

That said, I do have a couple commercial ones that are really great and not a bad price.
I bought these about 2 years ago and I am really impressed. Certainly more expensive than a box fan, but take up less space, make less noise, and are really effective. I checked out some of the more expensive ones before purchasing, but these ones had better reviews.

Too bad the dyson is so pricey, but you get what you pay for. A cheap box fan motor probably has brushes and produces poisonous ozone… silently killing everyone in the home. Maybe get a better motor if it doesn’t have one.

I have a Rabbit Air BioGS, for years now, well worth the money. Quiet, efficient.
