3M Airstream Filter?

[Steve Schlumpf]

For years I have been using my 3M Airstream while turning and it has worked well. I recently installed my last filter (AS-140-25) and went to order a couple more only to find out they are no longer available! Has anyone found a suitable substitute that we can use? Hate to think that 3M just left us without any options. I do plan on contacting 3M but wanted to reach out here first. Thanks in advance for any suggestions!

Run a quick Goggle search and come up with this. Jim

Thank you James. I also found those sites but was looking to only purchase 2 or 3 filters. Used to buy them from EnviroSafety for around $30 each. Now they don't even list them. Was hoping to find a place to buy single quantities as needed.

Thank you James! I had not come across those sites! Exactly what I was looking for!

I have the original Trend Airshield
When the filters were no longer available I did this


I took a used used filter to a factory where they made filters and asked if they had anything similar Though not an exact match or science they identified a product
The factory gave me a length of filter free of charge and I use this in my respirator

The Trend airshield has an accessory which can be used to measure the air flow


If your product has a similar accessory you could check the air flow of the replacement filter

Any luck on a replacement filter? Jim

[Steve Schlumpf]

Yes! I ordered 4 from the Mallory link you provided. The order has yet to ship but looking forward to having a couple of filters in reserve. Thank you again for your help finding available filters!

Glad to be of help. Worse come to worse you could maybe have built one like I did. Mine not only works for my turning but I could go see the new tourist attraction on the Oregon coast at Seaside. A whale washed ashore. I could approach from downwind. Jim
