Default Losi filters are good to wash and reuse... IMO..

I use losi fliters and change them up to 3 times in a raceday depending on conditions. I have around 10 of them that I wash and reuse. I wash them out with turps first then I wash em out after that with soapy water and then rinse the crap out of them, then let em air dry and re oil them. Havnt had one single problem doing that and both my engines run excellent. As for people thinking that micro bits of dirt will remain in the filters, this may be true, BUT! Dont you think that when you re oil the filters those micro bits of dirt will cling to the new oil? (ok thats my rant)..

Some good points here. IMHO, filters should be changed when dirty, or if in need of oiling. Some RC filters are designed so that the outer can be changed to restore peak flow, without disturbing the inner filter. Anytime a sealed filter system is opened, contaminates can get in, especially in dusty conditions. I'd bet that removing the air filter completely at a dusty track introduces more contaminates than leaving it alone. Also, if your getting air filter oil in your carb, your leaving too much on the filter. Anyone using a thin layer of grease on the sealing edges as an extra measure?

I dont put grease arount the sealing edges but i do allways make sure there is plenty of oil on them... Its not a bad i idea thou and i actully grease the edges of my air filter in my 1:1 Nissan 4X4 to help make sure they seal

I buy expensive motors so a $2 filter is the least of my worries. I toss after use and replace with new everyraceday. In a hobby where so much can and will go wrong why cut corners on such a cheap maintenance practice. New filter and fresh good airfilter oil. Just my 2cents

I change my filters after every race day. I use Losi filters w/ both the inner and outer filter oiled, then I put a dry Ofna prefilter over that.




At the end of the day, there's barely any dirt on the outer oiled filter and none on the inner filter.

I have about 10 oiled filters and 8 prefilters in ziplock bags in my pit box.

When I get low, I just wash them all at once with dish soap and hot water, and let them dry over night. Then I oil with Blue Dynamite oil, only because it's what the LHS recommends and carries. All of the Losi filters still look new, but the Ofna prefilters are a little more fragile. Easy to tear when pulling them over the filter housing.

Guys, if anyone is looking for filter foams at a great price, check out the Caster Racing filters, the Caster filter is a copy of the pro-line filter, 10 foams for $7.95, cheap enough to just toss. Awesome deal.
