Lately there is the availalility of .1 um micron filters. research has shown that these could substantually reduce bacteria and viral transmission in fluids passig through these. I has stated before that the best way to use filters is to put several in series of finer filtration. So attach the non luer-lock lide of a .45 to a .22, and then attach the non luer lock of that .22 to a .1. this way you can strain your fluids withut destroying, jamming, or perforating the filter!
Micron syringe filters and their importance, especially amongst those IV'ers who shoot pills, is something that has been noted here on Bluelight. I have learned a great deal about harm reduction in the IV drug use realm thanks to those who have shared their knowledge with the community here.
I am posting this because while the importance of why the micron filter should be used, with the dangers of insoluble ingredients within pills, has been discussed at length... I am still unclear as to exactly which type of filter is optimal for IV'ing certain pills (oxy, roxis, dexedrine, ambien, to name some common ones), or even for use while shooting dope for extra protection from the cuts.
Whether it gets thrown out or not, I want this thread to *NOT* be involved with the importance of the micron filter, or exactly why they are so crucial to the cardiovascular heath of an IV drug user. This has been established enough that most people are in the know. Instead, I merely want to get straight to the nitty-gritty as far as which ones are best!!
That being said, out of the types of micron filters available on the internet are the nylon wheel filters the best for filtering pills/drugs?? Or is polypropylene superior to nylon as a filtering material? Anybody who has any idea *please* share your info with your fellow BL'ers

!!
I am unsure of any other filtering materials other than nylon and polypropylene, and it's hard to get such information online. I've tried hard and both solid facts and anecdotal information is difficult to find.
Lastly, regardless of the filtering material in the micron wheel, which SIZES of filters are necessary for any IV user's arsenal?? Based on what I have heard here and there, 0.45um and 0.22um are the most popular... with many people doubling the two size filters in one shot to avoid clogging the smaller 0.22um filter. So the 0.45um filters the solution enough to let the 0.22um filter finish the job without any clogging... is this correct??
On a side note, I have seen different numbers thrown around - some of which are very close to the 0.45um and 0.22um filters I just mentioned. Namely I have seen 0.44um and 0.2um filters discussed here on Bluelight... are these the same filters, merely being rounded by some people? Or is there really a 0.44, 0.45, 0.22, and 0.2 all made distinct from each other (which seems possible but strange)... I dunno
I am going to make an order soon so I would love to get a little confirmation to make sure I buy the correct ones. Before I end this I was curious of one more thing-- do they make any filters
smaller than the 0.22um/0.2um filter?? And would the smallest filter, should it exist, be worth getting??
I hope I can get enough confirmation to make the correct purchase, and I also hope this thread can help clarify the matter for others who are trying to save their veins (a Q-tip is not enough, I know)... Take care all!
