I've only had one person supply me with details of alternative filter materials and sources. So this thread is a little incomplete.
The following is my opinion. I have owned an RE5 for 40 + years, have ridden around 20 different REs, worked on about 10 and been “involved” for 20+ years. I make no claim of expertise, only enthusiasm.
The bikes seem sensitive to air filters with the caveat that they vary widely in how they react to filter types. I've been able to change significant characteristics of an engine simply by changing the type of air filter (and reversing it in minutes).
Some bikes won't run without an air filter, some will, but are still better with than without. I'd suggest if you need to remove a good air filter for the bike to run, you’ve got serious issues elsewhere.
Overall, I’ve had the best results from stock air filters and those once supplied by Rotary Recycle. I still use them. However stock filters are no longer available and if they are, the could be dubious condition even if NOS. If you are running an original Suzuki RE5 air filter, inspect it regularly for signs of it breaking up. RE5’s are well known for ingesting old air filter foam.
Whatever filter, it should be oiled. Using Castrol GTX or your oil choice for engine lubrication is an option. As a general guideline and endorsed by Rotary Recycle, use the minimum amount of oil possible to give coverage through the filter. I sometimes suspend them for a day to ensure any excess oil drips out.
From member Timpa136:
In the USA, you can buy UNI Air Filters Bulk Foam 12x16x5/8”. Damped with 30 weight oil or UNI cleaning kit or K+N oil kit. Ensure the filter foam hangs out of the frame to completely seal the housing.
