Diy air purifier

So I saw an ad for this airosbysage air purifier on Facebook. And fuck if it doesn’t look like a simple ass build. Plastic control box with a hole cut for a car air filter. a fan pulling it into the box where it’s hit with a uvc bulb and exhausts out a hepa filter. Easily less than $100 to build. 0DFA0822-73B4-4736-A7A1-A5C74074E631.png

I think you are wrong. I believe it works on princip of high voltage, generating H2O3 which is able to sanitize the surface and everthing in the room. People here are using it and saying it works against WPM well. I remember that time when Renfro started to spreading info about this device. His very first claim was it works again Pm and botrytis, but later after testing it was only WPM. Anyway pretty usefull device for bigger grows IMo. It cost some money and it is not quiet, thats what I read. @DoubleAtotheRON is using it I think…

The h203 is generated by the uvc bulb. Ros is more often than not just code for uv irradiated air. Not knocking their hustle though, their target markets growing at larger scale than me and probably don’t have time to fuck around with unwarrantied diy builds. I’m guessing the fans a bit more powerful than your standard home hepa filter too. Need to figure timing though.

The AirROS does not use a UV bulb. It uses a high voltage chamber to generate H203. It does work against mold, WPM, pathogens, bacteria, etc. prob the most expensive part on the whole unit is the sensor. It’s about $1000 a year to replace, as it losses calibration over the year. It keeps the unit producing H203 at 30 PPB… billion. I’ll pull my panel and show you the inside workings of it as soon as my lights come on.

@Lenin1917 Your "timing" is what's going to make this a difficult DYI. Too much H203, and it's harmful more that helpful. To you, and your plants. Levels in the room need to be at mid 20's to 30 PPB. I has asked my Rep from AirROS about smaller, more affordable units for home growers, and he told me that the sensor is the same one used on all units, and that's what makes it expensive. 30PPB is a pretty small window, and it's super sensitive.

Neat, bit out of my price range, but neat. I’m still gonna try and rig my knockoff up, I bet it does at least as well as the regular household purifiers.

Or maybe I should skip the uvc and just use the filter. I haven’t had mold or mildew issues just want to limit the possibility in the future.

you can just get a box fan from walmart and a 3M furnace air filter which does a pretty good job too. there are ratings on the filters: think the higher # the better. the one i have can trap viruses like covid.

Yeah, they're expensive units. I think my 4014 was like $6300.00, but on a bigger scale, it's worth it. We had failed labs for microbes on a crop one time and that's what prompted me to buy this unit. That crop should have brought ~$45K, but failed microbes are reported to the State, and you can only sell those failed batches to processors, who don't pay shit for it. Ended up losing our asses on that crop at less than $5000.00 wholesale, so you can see in my situation where it's cheap insurance.

Damn, I bet that fucking hurt. Ain’t no testing in prohibition states, molds still not something we wanna smoke though. But if I had that much tied up in my grow I’d definitely opt for the pro unit too.

Our State threshold for microbes is pretty small margin for error. 10,000 Colonized Fungal Units… it’s small!.. you can’t really even see 10K CFU to the naked eye. Every since we’ve had this machine, all our labs come back with “none detected” on microbes, and I follow VPD all the way to the finish.

I don't do walmart, but furnace filters are cheap, effective and sold everywhere. Put them on tent intakes or just slap one on a card board box and use any fan you have, better than most air purifiers in stores.

I have a 4" carbon filter in the living room with a 1 watt COB fan on top, it's nearly silent.

Did some digging, man ozone sensors really are that expensive. Cheapest I could find for a single sensor is still $400 and it ain’t exactly plug n play.

Yep.. Expensive stuff! Speaking with Michael at AirROS, there's really only one solid PPB sensor out there, and that's who they use as a vendor. Once a year you gotta replace the sensor, twice a year the chamber, and air filter. Total, about $1000.00.. but!, you're basically rebuilding the whole machine, and once you get those parts refreshed, it's like a new one.

For your entertainment... the inner workings of the AirROS 4014. Im not an electrician, or engineer, but here's peek of the guts of this thing...

hi, I picked up a unit
do you have any tips or settings you use regarding using it in the flower room and dry room, thanks

Just keep an eye on the display, and make sure your power factor is keeping the H203 in the 30ppb range. You may have to dial up the power factor as they mature and start throwing off more VOC's, and can't keep up with let's say, power factor 60%.... if you see your numbers falling, just turn up the power factor up by 5%, and wait 24 hours for it to settle and see where you're at. I've seen my power factor up to 95% if I got a really dank ass crop going in late flower.
