The MaxFlow® filter kit to fit Stihl® Models MS661 chainsaws with the polyolefin HD2 filter. Kit includes everything you need to convert your saw:  Two High flow, washable foam elements, (one green for standard cutting and one white for extreme cutting  conditions), Maxflow cage, custom backing plate and an OEM style close fit rain cover.

MaxFlow Filters are the ONLY aftermarket filters that are 100% USFS approved. Don't risk being shut down on Forest Service property.  Reference the (MSE) SAG HS type A. 

MaxFlow® air filters trap the smallest particles while flowing full CFM for up to 30 times as long as stock air filters.  This helps your saw breath better during prolonged use in adverse conditions, resulting in smoother running and more power.  Unlike pleated filters, MaxFlow filter elements are washable and re-usable so they last longer and cost less.  Foam elements do require the use of foam filter oil (sold separately).

For more than 30 years MaxFlow® filters have featured ONE PIECE foam elements with no glued seams to fall apart.  No seams mean longer lasting elements with no chance for dirt to penetrate.  Don't be mislead by glued foam where gas and vibration causes the glue to fail.

Does the job
Size: 10 Ft (Type B with Clamp), Color: White
I think the clamp could be some show shorter, but the product looks nice and minimalistic and works perfectly.

Solved Specific Need
Size: 10 Ft (Type B with Clamp), Color: White
Nice product which solved a problem of needing USB power clamped to a very thick work table. Most power strips with a clamp do not accommodate thick tables between 1.75" and 2" so I was happy to find this one. Successfully provides power to all my USB devices even a laptop (although charging is a bit slower compared to the OEM power adapter).

One minor bug
Size: 10 Ft (Type B with Clamp), Color: Black
I received this today and mounted it to the table I have next to my recliner. I plugged it into a remote control outlet so I can turn everything off at once. I used two of the AC outlets for the power recliner. I then plugged a USB powered fan into one of the USB-A ports. I plugged the power cable from a set of speakers positioned next to the headrest of the recliner into the other USB-A port. I used one of the USB C outlets to charge my tablet. When I hit the switch on the remote control to turn off power to the strip before going to bed I discovered a bug. The only way I can describe it is a cross port power bleed. After killing power to the strip my speakers were still playing, not well as they had static. I discovered by trial and error that if I unplugged my tablet the problem stopped. Apparently if you have something with a battery plugged into one of the USB ports and have something plugged into the other USB ports it pulls power from the device with the battery to try and power the other devices plugged in. Other than this one problem it seems to be just what I was looking for.

Mounts to desktop
Size: 10 Ft (Type B with Clamp), Color: Black
Helps keep the desktop clutter down. Sometimes I need to charge flashlights, earphones, hearing aids, portable battery chargers and the like. I don’t want to plug these onto my computer so this unit fits that need. Sturdy desk mount so one hand plugging in and unplugging usually works fine.

Small and does the trick. I’m glad my USB hub will stop falling off the table!
