Nope. And here’s why.

The KLR Filter is designed to remove particles down to 1 micron from home brews. Most yeast cells are 1 to 2 microns in thickness, and larger particles are easily filtered using the KLR Filter system.

Finer sediment or silty residue is smaller than 1 micron. Do not let the siphon tube suck it into the KLR filter and into your carboy or bottles. Let it stay behind, as undisturbed as possible, when racking or bottling your home brew.

The only way to remove this type of ultra-fine residue is with a vacuum or pressurized system with a filter opening of less than 1 micron. These types of filters often strip color and flavors out of your home brew. I simply do not use them. My home brews have a rich, full bodied flavor and vibrant color as a result. This includes wine and beer.

Filter bodies, filter replacement cartridges, gaskets and seals can all be ordered from

The filter base is pretty heavy duty, so if it breaks for some reason it had a pretty rough life. They are closely inspected and functionally tested. If it is defective please return it within the 30 day policy window for a replacement. The filter base is not sold separately from the filter kit.

Absolutely! The filter is designed for gravity feed only. Although it is pressure tested, this is only to test for leaks prior to assembling and packaging the product. Do not subject the KLR Filter to high pressures. It is best not to use a siphon for beer, as the bubbles in it will vapor lock the tubing at the top of the siphon. It is ,much easier to use a fermentation vessel with a spigot and use tubing to connect it to the KLR Filter.

The best results I have had so far with beer is using the 50 and 20 micron filter cartridges, and I have filtered ales down to 10 and 5 microns. I would not suggest going much lower than 5 microns – that way more of the good stuff in beer is retained and you don’t erase out the character of your brew.

Yes, but they are NOT reusable! The filters are made of a spun plastic material and can be placed in the recycle bin after you are finished filtering your batch of beer or wine.

NOTE: Do not rinse and hang to dry, then reuse them. They retain liquid and will get bacteria in them at some point, ruining your brew if you try to reuse them. They are made to be discarded after you have filtered your batch of home brew.

No. Once you have run your home brew through one, discard it into the recycle bin.

The filter cartridges are designed to be used with one batch of home brew. They will filter up to 20 gallons (I have tested them that far – they might go further). Most home brew batches are 6 gallons.

Never use the same cartridge between home brews unless you are blending them as you filter them. The filter cartridge retains some of the home brew and the next use will push it out into your other batch.

I often blend wine batches of similar grape varietals, such as Pinot Noir with Merlot. I will make 3 kits, let them go through the fermentation and racking processes, then blend them together before I bottle them. My technique (which works very well) is to use a 5 micron filter while blending.

For beer I recommend only using the 50 and 20 micron filter cartridges. You really don’t need much more than that, although I have used 10 and 5 micron filters with clearer brews, such as pale ales, etc.

My best results with beer to date have come from using the 50 micron filter cartridge to filter the beer after primary fermentation, typically while transferring it to the next fermentation vessel. Then I filter it again after secondary using the 20 or 10 micron filter, which is typically just before adding the priming sugar and bottling the beer.

For wine I use the 5 micron filter cartridge after the first clarifying, which is 3 to 4 weeks after I added the clarifiers and stabilized it with a small dose of potassium metabisulfite.

My best batches of wine have been the result of following this schedule:

  1. Primary fermentation – day 1
  2. 3 to 4 weeks later – rack to a carboy, the clear it (stir out the gasses, add clarifying agents, etc.)
  3. 4 weeks later – use the KLR Filter with a 5 micron filter cartridge and transfer the wine to another carboy.
  4. 4 weeks later use the 1 micron filter cartridge when you transfer the wine to another carboy

My wines are really excellent after about 4 or 5 months. Many wine kits say they are done in 6 weeks, but the results will be disappointing. Take your time with wine and let it age. You’ll be much happier with the results (as will your friends).

Each filter body is pressure tested prior to shipping, so this should not happen. The filters have a 30 day warranty. Return everything for either a refund or replacement.

The easiest thing is to run some hot water right along the seam where the body screws into the base. Let it get warmed up then then try again. It should unscrew relatively easily.
