Ultra Duster Industrial Strength Compressed Air Duster Cleaner 10 oz., 12/Pack (UDS-10P12)

Arrived in a prompt manner, in original factory box inside another box so shippers could not hurt them. Best price I could find.

Good product. I use it to blow moisture out of my cannula as l am on oxygen therapy.

All of the cans arrived seemingly unbroken, and as I didn’t want to remove the plastic covering on the caps until ready to use, I only tested one can and did a visual, with shaking each can, to insure none were empty. This is my first brush with blue cap Dust Off, but have had great success with the black cap Falcon so figured they were worth trying (and being less expensive helped too). Only difference that “might” be found is the can cools somewhat quicker, but not instant freeze, which when happens slows/decreases the pressurized “air”, but the air pressure works just as forcefully as other brands I’ve used and you aren’t supposed to use a continuous blast anyway - plus there is a big bonus to these as well, as unlike the Office Depot brand that sells for less, these don’t frost up instantly, and are Not overly filled with bitterant, so they don’t spit liquid out all over the place, like a keyboard, in the computer/DVR vents, or on the TV screen when dusting out the frame after wiping it down, if not held perfectly level when used. Overall so far,, glad I made this purchase.

I don't use this as a spray, I use it in several of my vehicles A/C to replace R134a. This brand is always HFC-152a where other brands may use one of 3 different HFCs. You don't want a mix so stick with Ultra-Duster. This is colder (barely) than R-134a and the high-side pressure is lower than R134a at high temperatures; easier on your compressor. If you do swap to this, put a good vacuum on your A/C system for several hours. Legally, you're required to recapture all of the R134a because it's been declared a greenhouse gas 30x more than carbon dioxide, oddly soon after the DuPont patent expired. R12 was fine with the ozone until the DuPont patent expired. Once you switch to this, you can forget about the legal stuff, it's meant to be sprayed into the atmosphere. And it's currently under $5/can. My trucks use 3 cans for a total fill, little foreign cars take two cans. I believe some European manufacturers are currently using it. If you attempt this, use gauges. Low side should be under 50psi, high side around 200+psi. 250psi is too high. Be sure the radiator fan is running or the high side will look high but will drop once the fan runs. It's compatible with PAG oil so it can replace R134a. DO NOT replace R-12 which uses mineral oil unless you flush the entire system, drain the compressor, etc. You'd need to be desperate but, considering the price of R-12, I'm getting there. I have two Rangers that have been running Ultra Duster for over 50K miles each with zero problems. Do your own research before putting this in your car. It works in mine but I can't be responsible for yours. Edit- Don't replace R134a for no reason. If it's working, leave it alone. All of the vehicles I've put it into had more than minor problems which warranted a switch.

Fairly good price. Better than one can at a time from Wally World. As a locksmith, I use this very often to get rid of "stuff" that has been gumming up delicate springs, wafers and pins in the lock body. Good buy. Good to have enough on hand that I don't run out.

Perfect for cat deterrent motion sensor sprayers

Works great at a reasonable price

I finally Busted out these Ultra Dusters and like them very well. They have a good grip trigger for your finger and work well, but the little extension straw is a little short. Not as long as others I have used and that extra inch matters. Still it works well. No problem it Blows.
