Clean up your beer and give it that sparkling clarity you see in commercial brews. Filtering removes yeast and dry-hop sediment, both of which can impart off flavors. It's also a great way to give your beer that extra edge in competition.
This two-pack of filter pads are for use with our FIL45 series of plate filters.
Polish pads will provide between 1-2 Micron filtration.
I like these filters. They do a great job in clearing up your beer. I would caution that these particular ones (polish) do not do as well with lots of particles and thicker beers. You can run it through one of the coarser filters first if need be. Otherwise, stick to lighter beers.
Overall this is a very nice product. I have filtered beer in two different ways in the past. I started with the aquarium style filter, but I was not satisfied with how much beer seemed to be wasted in the process and the fact that the filter leaked no matter what I did. So, I switched to the plate filter product for which this pad is used. I definitely prefer the plate filter to the aquarium style filter. I ended up just using the aquarium style filter to carbon filter (dechlorinate) my brewing water from the hose - which it does well.
The plate filter does a great job filtering the beer. It comes out brilliantly clear. It also works well to filter the yeast out of ciders that you want to back-sweeten to avoid possible secondary fermentations. This way you mechanically remove the yeast and don't have to add chemicals to kill the yeast (if you're into that kinda thing).
However, a word of caution:
For awhile I had gotten really into filtering my beer. I loved the brilliantly clear character that filtration offered and made the beers look professional. However, I have noticed that filtering the beer does (at least in my hands) reduce head retention. The beer ends up heading a bit during the filtration process and once these proteins are used for heading, they don't come back. Also, if you are filtering very hoppy beers, some of the hoppiness (likely from filtering out polyphenols) is filtered out. I have started doing experiments with clarifying agents (gelatin to knock down the yeast followed by PolyClar do knowdown some of the haze from polyphenols) to clear the beer without stripping as much of the head potential and hop character. I have had early success with this technique and I plan to employ it again in the near future on a recent batch of IPA.
I would say that if making a beer that is supposed to be very clear - Pilsner for example, ciders - then the filter works great. I stopped using it on my IPA's though.
