Description
Gravity Home Brew beer filter to remove spent yeast and haze from your beer. Creates a much clearer beer without impacting taste.
Transparent 10″ filter housing with 3/4″ Bsp ports with air bleed button on top, housing has screw in 13mm barbed hose fittings with a shut off tap on the outlet side to help remove air from the filter, also helps control flow if bottling. 2 meters of 12.5mm ID clear food grade tubing is supplied.
The 12.5mm ID tubing will push onto a standard fermenter tap. Ideal for removing sediment & haze from your home brew without affecting the beer taste and will still allow beer to work in the bottle. Gravity filter beer from your fermenter into an empty keg or into bottles.
USA made quality pleated washable 10″ x 2.5″ filter cartridge, these filters can be washed out and reused many times before replacing.
Instructions on how to use and cleaning are included.

Choosing a Beer Filter Micron Rating
This kit comes with three filter choices and a ‘no filter’ option if you’d like to use a different type of filter.
We also have Pentair blue cap filters available if you are looking for a more affordable option. Simply choose the ‘No filter’ option then buy your desired filter seperately.
The default options included with the kit are:
Option 1: No Filter
This option includes the housing, fittings and tubing but no filter.

There are also caged DOE filters available, which have a hard plastic cage around the filter’s pleats. Caged filters can be backwashed more easily as the cage prevents the pleats blowing out during reverse flow. View DOE caged filters here.
Option 2: 0.35 micron Nominal
USA-made Harmsco filter rate at 0.35 micron Nominal. Will remove most yeast from the beer. (up to 90% at 0.4 micron & 10% at 1.2 micron) Filtering will be slower than a standard 1 micron Nominal.
Option 3: 1 micron Absolute filters
Absolute filters are rated to reduce 99.9% of particles at a specified size. This makes them much finer than a nominal filter of an equivalent rating.
A 1 micron absolute filter can be used for bottling beer, but it is not the standard for homebrewing as it may cause flavour loss and slower filtration. Absolute filters are typically reserved for sterile filtration where yeast is completely removed, requiring you to add back bottling yeast later or artificially carbonate the beer using CO2.
The advantage of going this fine is that it will reduce haze producing an extremely clear beer. Some homebrewers who enjoy crips, clean lagers will use a 1 micron Absolute for this reason. When using a 1 micron Absolute this way, it helps to chill the beer before filtration. Please refer to the FAQ below for more information.
Option 4: Harmsco 1 Micron Nominal (Most Popular)
A premium USA-made filter which reduces particles down to 1 micron in size.
A 1 micron nominal filter will still allow some yeast through for the beer to work. (up to 90% at 1 micron & 10% at 2.5 micron).
1 micron is the most popular choice for homebrewers as it provides decent filter lifespan, improved beer clarity, and retention of flavour with a wide range of beer styles. A great starting point.
Frequently Asked Questions
Which Micron Rating Should I Choose?
- The type of beer you are working with (an ale may require less filtration than a lager)
- The end result you are looking for (how clear do you want your beer)
- How long do you want to get from each filter (a finer filter will block faster)
In most cases, a 1 micron nominal filter is a good starting point for homebrewers.
What Is The Difference Between Nominal and Absolute Beer Filters?
A 1 micron nominal filter will remove “most” of the particles which are 1 micron and larger. The precise level of reduction will vary between filters, so a low quality 1 micron sediment filter may only reduce 70% of 1 micron particles, while a high-quality USA-made harmsco might be reducing 95% of 1 micron particles.
A 1 micron absolute filter has been tested in a laboratory and shown to remove 99.9% of particles which are 1 micron and larger.
The nominal rating describes the average performance while an absolute rating is a guarantee of a minimum capture efficiency.
The variability of nominal filters means it is impossible to say how they rate against an absolute filter. A well made nominal filter could capture 30% more particles than a poorly made one.
Pros and Cons Of Using a 1-micron Absolute Filter
Pros
- Crystal clear beer
The 1 micron Absolute will remove virtually all yeast particles, haze causing particles, and sediment, resulting in a beautiful clear beer. - Crisp, clean flavour
Removing the bulk of sediment and yeast gives the beer a clean flavour. It can also reduce tannins proteins which add negative flavour compunds. Ideal for lagers. - Lasts longer in your fridge
Removal of microorganisms improves shelf life
Cons
- Will require artificial carbonation
1 micron Absolute filters will remove the yeast which produces CO2 during bottling. As a result, you will need to use a keg to force carbonate - May reduce flavour
If filtration is too fine, it may begin to strip out beneficial flavour compounds. - Makes brewing harder
The additional carbonation process adds complexity and cost - Slow filtration
The pressure drop caused by the fineness of the filter means it takes longer for your beer to move through under gravity pressure - More frequent filter replacements
Because the filter captures more, you may find it clogs faster, resulting in more frequent replacements
