Pipe Filters?

Totally agree with Charlie (Isett2860). I use a filter too depending on the blend I’m smoking. Especially when it comes to tongue bite and nic hit.

Never, for me. However, I always dry the tobacco thoroughly, pack fairly loosely and use a pipe cleaner mid-smoke if needed. Everyone finds their own path with all things related to pipe routines. Explore, trying all methods, and choose what works for you. Enjoy!

My first pipe has a 9mm filter and I didn’t like it so I chucked the filter and smoked it as is.
I’ve tried smoking my cobs with filters before but just found I didn’t care for them with the filter in. Ended up getting forever stems for them.
Buy hey if you like them more power to you they are just not for me.

And just a reminder. If you get a 9mm pipe and don’t like the filter. You can get a reducer from most
of the online retailers. For about $1.00 usd.
Some come with them when new.

I have two pipes that came for 9mm filters. I use filters in those pipes, but all my other pipes are non filter. I'll use filters when I smoke those two, and don't find it offensive. I'll only use the 9mm charcoal filters from Vauen. Paper or balsa filters do not appeal to me in the least. Do they improve or reduce smoking pleasure? To be honest I really don't notice a difference.

Ahh, I never thought of the Brigham pipes! Can you pass a pipe cleaner while smoking despite the filter being fitted? 

or just smoke then without a filter or reducer. I've never noticed the difference.

I actually had a pipe the wound not take a reducer either.
but I will use a filter, so I reach for it on some tobaccos 

I've never had any pipes that would take a filter, so I'm not really much help. I found that the combination of tobacco that isn't syrupy, with briar that will wick moisture to the outside of the bowl, and liberal use of pipe cleaners takes care of any smoking issue for me. I also gravitate to pipes that aren't too short, which gives a cooler smoke. Of course, your mileage may vary.

But it's a legitimate question and there isn't any right answer, just what works for you.

Ok, so here's a SITREP.
I have been smoking new Brigham, Rattray and Savinelli pipes over the last few weeks. The Brigham has the rock maple system; the Rattray, a 9mm charcoal activated filter; and the Savinelli, the 9mm Balsa wood filter. Allow me to share and summarize my impressions.

1. Draft Restrictions.

a. The rock maple allows a pipe cleaner, but it stops where the metal part fits in the airway. It will not go in the tobacco chamber but I have not experienced any blockage while smoking. The draft was pretty good; I can't say I felt any significant obstruction but it still requires some adapting compared to a 4mm airway. I do take the filter out after every smoke so it can dry.
b. The 9mm charcoal activated filter does restrict the airway but it's not as dramatic as I was led to think watching some Videos. It does require adapting, particularly with the puffing cadence; otherwise, the pipe can become pretty hot pretty quickly. I tried smoking with the same filter twice and it didn't work well, it smoked much less clean. Curiously, I never had to remove the tenon because tobacco bits were obstructing the airflow.
c. The balsa filter does not restrict at all, or barely, the airflow. Which is absolutely weird as the 6mm, from memory, restricted it significantly. However, when you insert it, you must leave about 2 cm sticking out from the end of the tenon or else, good luck in taking it out as it's very soft to the touch and breaks easily.

2. Tobacco taste.

a. With the rock maple system, the tobacco taste is not narrowed down significantly. What is interesting is that when smoking with a new filter, the taste, for the first 5 min, is reminiscent of a CC. Then it goes away.
b. With the charcoal activated filter, taste is narrowed down to a couple dominant but still distinct flavors.
c. With the balsa filter, there is about no loss of flavor. I can taste, for the first few min, the balsa when I start a new filter but it's temporary.

Overall, the mouth feels 'cleaner' smoking with, than without a filter.

3. Reduction of tongue bite/harshness/moisture.

a. The rock maple does not significantly reduce tongue bite, but enough that it does make a difference. The smoke is a lot less harsh from the moisture but is not entirely eliminated. Still, enough to make a difference: my gum never became irritated despite breaking in 4 Brigham pipes over the course of a couple weeks.
b. The charcoal activated filter eliminates tongue bite almost totally. The smoke is not harsh nor moist. My gum never became irritated.
c. The balsa filter does reduce tongue bite, harshness and moisture but not significantly so. If I am not careful, my gum can manifest a beginning of irritation but it has never been pronounced.

4. Cost.

a. The charcoal activated is the most expensive option as I have to replace the filter every new smoke.
b. The balsa wood performs decently the first 3- 4 times but I would not exceed 5 smokes with the same filter as the balsa will become saturated and have adverse effects.
c. The rock maple is the less expensive option as it's good for several smokes as long as you take the time to remove it from the tenon after every smoke and let it dry. Some rinse it through hot water to prolong its life duration. I'm not there yet.

5. Conclusion.

- The Brigham pipes, overall, are not what I consider to be sexy pipes by design. Sadly for me, it's the only brand using the rock maple filter. Nevertheless, this filter, despite some cons on the maintenance level (the filter can be sometimes a bit difficult to remove after the smoke and I had to sometimes try a couple new filters before finding one that fitted the tenon nicely), works pretty well for me as the smoking is fairly restriction free. Despite traces of slight tongue bite, my mouth and my gum do not become irritated and the smoke feels fairly clean. And each filter can be used several times before final dispatch. It would be, so far, my preferred filter even though I'm not crazy about their pipes.
- The charcoal activated filter allows a wide range of pipes to choose. In fact, more and more pipes are available with the 9mm filter option. Some brands almost exclusively offer this option only. It has the best result in terms of comfortable smoke, despite the relative loss in flavor. No tongue bite, no harshness, no mouth or gum irritation. Smokes real clean but only if the filter is used once, no more. But the fact that the airflow is more restricted and demands a constant vigilance to work out makes it my second preferred option.
- We all know Savinelli makes some really sexy pipes. The balsa filter seems to improve after a couple smokes but still requires caution on my part as moisture and harshness are less reduced with it than tongue bite. In my case, it is the less preferred option as my gum can remain sensitive if I am not careful when I'm smoking with it. Still, the irritation is much less severe than without a filter. To alleviate this, I will experiment with the charcoal activated filters that Savinelli offers. Because of the size of the balsa filter, charcoal activated filters such as Peterson and Dr. Perl are too loose in the tenon so I will use the ones designed specifically for Savinelli pipes which are, unfortunately, rather expensive.

To conclude, personally I will only smoke with a filter from now on as a non - filtered pipe generates gum irritation. I believe my issue is that I developed a sensitivity to the harshness generated by the moisture. Hopefully, this will help people who are debating the 'to have or not to have' filter option.
I started this journey unfavorably biased toward the filter option and can say that I stand corrected. For those who have, or have recently developed an oral sensitivity to pipe smoking, a filter might be the solution. Or, simply, if you are looking for a cleaner smoking experience.

Roger that... thanks for the sitrep.

Thanks, gents, I hope people will find this summary helpful.
