The occasional cleaning of my m401 atomizers keep the draw like new.
I soak them in rubbing alcohol for a while, rinse, blow out, then dry.
Same here. No dead atties yet on my 401.. that is exactly what i do and nothing else.. Well.. I do blow them out once or twice a day... and do the alcohol soak about once a week, but never rinse with water so I guess not quite the same. I let the alcohol evaporate before using again. I am thinking of using vodka instead of rubbing alcohol for the soaks as this may be better since I don't rinse them with water.
I AVOID water.. I don't know why, but I rinsed and soaked in water one time and I had a bad feeling so I just don't do it.. I get great vapor but i do mix down 36mg with some PG and VG and flavorings if needed. Like a little loranns watermelon flavoring to add to the watermelon nic
juice when cutting to have nice flavor. or just make my own 0-nic juice for in between cravings.
On the passthrough, I get GREAT vapor even with uncut juice but the draw is slightly harder.. it was very hard draw at first, but the passthrough is now getting a lighter draw as i use it more.
Just to add.. my favorite mix is coffee and vanilla.. I strictly dip... this mix tastes great fresh dipped on the atty.
I definitely get more vapor when the atty is nice and warm... so even on the 401 I do a primer puff sometimes (though not needed with this model)... also never get juice in my mouth. I used to when I used carts.
