Micron Rating: 

The Clarifier is a new, reusuable, stainless steel, multistage filter cartridge for beer and wine. Designed to fit in any standard 10" filter housing, it comes in 1, 2, and 5 micron versions. This filter has a two stage design, with the first stage trapping hops and other large particles while the second stage filters out yeast and protein particles down to the filters rating.  Being reusable, the Clarifier by Hastings Brew Works pays for itself in just a few filters compared to other disposable equivalents. The clarity that is achieved by this filter would normally take months of waiting for the particles to settle out of your beer.  As a bonus, forcing your beer through the filter under CO2 pressure helps begin its dissolution into the beer, giving you a jump start on carbonation.

The example photo shows how much yeast and trub was removed from a 5 gallon batch of a 7% IPA using a 5 micron Clarifier.  This beer had an unusually high yeast load and was dry hopped with 2 ounces of pelletized hops 3 days before filtering.

Choosing the Right Filtration Level:
There are varying opinions regarding the right filtration level, as well as differing data regarding the size of yeast cells and other particles to be filtered in beer.  Some literature suggests yeast cells are between 5 and 10 microns in size; other recent studies show the mean size is actually 3.5 microns and proteins in the beer account for the particles at the 5-10 micron level.  In actual practice all versions of The Clarifier are effective, it’s your personal preference that determines the filtration level you desire.

Whichever filtration level you choose, keep in mind that filters are not 100% efficient so some amount of yeast will remain in your beer after one pass through a filter.  So, beers with very high yeast loads will contain more residual yeast after 1 filtration pass than those with low/typical yeast loads; for beers with high yeast loads some brewers will choose to use two filtration passes or use two filters in series in one pass.

There are styles which call for unfiltered beer, and some people feel all beers are better unfiltered.  On the other hand, many believe unfiltered yeast cells and trub cloud and mask the malt, hop, yeast esters, and other flavors you designed into your beer.  Clarity level in beer is another factor that depends on personal taste and filtration level.

Much of brewing is about controlling the process to achieve repeatable excellent results.  Filtration at your chosen micron level helps you more easily and consistently achieve your desired flavor profile batch to batch by removing uncontrolled variables.  It allows your recipe to shine through.

Not to mention, it helps you enjoy your beer sooner!

Filtering Process:
There are many different ways to filter, and each brewer will adopt their own process that works best for them.  This is an overview of one method that works well.

Filtering is accomplished by racking the beer from the fermenter into a keg and then filtering from that keg into the final conditioning/serving keg under CO2 pressure.  For best results cold crash the unfiltered keg for 1 to 2 days at approximately 30F before filtering into the conditioning/serving keg.  The beer should not be stored under CO2 while cold crashing.  The cold crash step is recommended but not required.

The filter sits between the 2 kegs, connected to the ‘out’ ports of both; this allows the CO2 to force the beer out of the full keg through the filter and gently down the dip tube of the empty keg.  The full keg is sealed while the empty keg has its lid removed.  (If you are concerned about leaving the lid open on the receiving keg, one option is to cover the opening of the empty keg with a paper towel thoroughly wetted with Star San.)

Ensure the hoses connected to your filter housing and kegs are securely clamped and the hoses are rated to an adequate pressure.  The pressure required will be dependent on the amount of particulate you are filtering in your beer, and the filter housing port size (1/4” ports on the filter housing require more pressure to filter than 1/2” ports).
The cold crash step is important and you’ll see better results including it in your process.  Target a pre-filter beer temperature as close to freezing as you can, without actually freezing the beer; 30°F is a good temperature target.
Filter slowly for best results.  Target a flow rate that will filter 5 gallons in 1 hour or longer.  For filter canisters with 1/2" ports/hose start at 10PSI, for canisters with 1/4" ports/hose begin at 15PSI.  Slowly increase the pressure until you reach the desired flow.  Monitor the flow rate and increase the PSI accordingly as more pressure will be needed as the filter takes up solids.  It’s typical with 1/2" ports to reach a final filtration pressure between 20 and 35 PSI; 1/4" ports will reach a final filtration pressure of up to 50 PSI, depending on the level of yeast and trub in the beer.  As a reference point, typical home water systems which use the canister filters operate at 65PSI, with a normal range from 40 to 80PSI. Remember, lower pressure and longer time is more effective.
Filter slowly, relax and have a homebrew while the filter does its work for you, including the jump start on carbonation.
The amount of yeast and trub you see in the canister after filtering will vary considerably based on a number of factors including the yeast load in the beer filtered, how much trub was present, micron level of the filter used, speed of filtration, etc…  For instance, a low gravity beer with a very low yeast load will have only a small amount of yeast in the canister after filtration but when you backflush the filter to clean it you will see the yeast cloud the water as it is flushed from the filter.
When finished filtering, immediately backflush the cartridge while still in the filter housing assembly.  Connect hot tap water to the ‘out’ side of the filter assembly and backflush for several minutes under full tap pressure until the outflow water runs clear.  This removes the trapped particles within the micronic mesh.

Next, clean via your normal process.  Recirculating a cleaning solution such as PBW through the cartridge/filter assembly per cleaner directions with a small self-priming or submersible pump is an excellent method.

This is my second one of these, they work great the trick is to get the beer cold and filter very slow

I like the idea of being able to reuse the filter this filter will pay for itself after only a couple of uses

These are really nice filters I really like the idea that you can clean them and reuse them so far they have worked very well for me.

Not worth it
I bought a couple of these hoping they would be both sterilzable and reusable. The gasket would never survive even a minimal steam sterilization cycle. Additionally, the filter seems to clog way to fast. I don't know if it's a surface area problem or what but after several tries I tossed them.

Could be better
I've tried to filter 3 batches with the 5 micron filter.

Had high hopes for this being a reusable filter, but it really didn't work very well. It works kind of like a strainer, just with a finer mesh. As a result of suffers from the same problem as a strainer, it clogs very quickly. This is what's happening to the people that are having trouble pushing the beer through the filter. If there is any amount of yeast or particulate running through the filter it clogs very quickly. The remedy is to either up the pressure, which doesn't help much, or to rinse the filter midway through (possibly multiple times). I just don't see this as a viable alternative. If I have to clarify the beer to the point that I'm pulling little to no particulate through the filter, then what's the point of the filter.

I'd probably send it back except it's probably been too long since I bought it to get a refund.

My suggestion would be to go back to the spun filter since you already have the water filter housing setup. Or the plate filters seem to show promise. Assuming you want to filter. On the other hand, I've had great luck with just gelatin or something like biofine.

Dont Buy
I bought a 1 and 5 micron as I was having issues with the disposable BevBrite filters--the sizes were not fitting the filter housing consistently `1/8" too tall.
Bottom line: it took me 4+ hours to filter 10 gallons at 50PSI. The website says it can be a lenghty process but over 2 hours for a 5 gallon keg is ridiculous. It does filter, but nothing better than the disposable versions. If you have the time and want a reusable option, this is for you.

I must be using it wrong.
I have used it the 2 micron filter twice on two separate batches of beer. It filtered nothing.

I have used the spun filters before and while the beer after being filtered is initially hazy, it eventually is clear. However, spun filters don't filter nearly as well as the paper filters in a plate filter.

This product doesn't filter at all.

I took particular care both times to follow the instructions. I made sure my "in" line was hooked up to the unfiltered beer. I pushed starting at lower pressure (about 4 psi), but had to increase the pressure as all that seemed to be going to the receiving keg in the "out" line was foam. I used it on a dark Czech lager tonight and had to crank the pressure up to 12 psi to get beer (and not foam) running through the out line. Filtering also took a very, very long time (I wish I would have timed it).

After both filtering sessions, I gave a visual check. Nothing was caught in the filter. I back-flushed the filter with hot water (following the instructions) and nothing came out.

The first batch I used this on was a Rauchbier. I'm almost down to the end of the keg, but the beer is as cloudy as the day I transferred it out of secondary.

I was really hoping to have a re-usable filter that I could use in the much easier to use cartridge filter. But I'm disappointed in the results in using this product, so I guess it is back to the plate filter and paper filters.

Unless somebody can tell me what I might be doing wrong...

Excellent product
This is a really great product, and I'm glad I stumbled across it. I had used standard disposable filters before and was kind of disappointed with results. I got the 1 micron clarifier, and I am really impressed. I've been brewing for 6 years now, and have never seen homebrew this bright and clear. And it's easy to clean and reuse! A must have if you plan to filter.

Highly effective, reusable filter
I was compelled to try this device to gain better clarity from my beer without filling landfills with dozens of disposable cartridges. It meets that need perfectly. It readily inserts into a regular household water filter housing. In my experience, depending on the sediment level in your beer, it filters beer from a range of very easily with low pressume and perhaps only a half pint of loss per 5 gallon batch, all the way TO (on the other extreme) very effectively but requiring high pressure, an intermediate filter cleaning, and up to two pints (total) of loss on a high sediment 5 gallon batch. The results in both cases are excellent. The filter cleans readily by backflushing. I soak mine overnight in a thermos filled with PBW (to conserve volume) and rinse to finish cleaning. The filter can be sterilized in StarSan or by boiling. I have used mine with clarifying agents including gelatin, BioFine, and bentonite. It works fine with each, but I would strongly encourage allowing time for all sediment (whether from clarifying agents or cold crash, etc.) to settle and to avoid disturbing sediment before filtering, so as to keep the filter clear of unnecessary particles and ease the filtration process and reduce the beer that is lost in the process. I highly recommend this item.
