Katadyn Varyn Water Filter Review - Everything You Can Ask For

Who Needs This Product?

The Katadyn Vario Water Filter is an economical option for casual-to-mildly-serious adventurers in groups of up to 4. In other words, it is a budget-friendly product for most travelers. Why for casual and mildly serious adventurers? That’s because large adventuring groups will do well to choose a water filter with a larger capacity.

Still, the Katadyn Vario Water Filter is versatile and has optional filter installations. If you want a more enhanced filtration system and longer shelf life, then be on the ready for those optional buffs.

Why We Recommend This Product


As far as effectiveness goes, you need to understand that water filters can’t compete with water purifiers as the latter deals with viruses and does a far more thorough clean-up job than the former.

With that being said, the Katadyn Vario is a water filter with international acclaim and certifications. That means that the product is highly effective. The water filter takes care of visible sediments and harmful chemicals, and also makes water taste plain better, with no odor.


At a height of 6.5″ and 15 oz., it is a lightweight water filter fit for backpackers. However, we should point out that lighter water filters exist, and Katadyn has many of them. Still, 15 oz. is light enough.


We feel that the Katadyn Vario Water Filter is a tad tall. But we like it that way. It gives off a dependable vibe, if that makes any sense. Moreover, the design kicks butt; it is extremely edgy in all the positive sense of the word. Especially the ceramic layer adds a robust look to it. Normally, water filters have a vertical pump, but this one has a side pump, making it unique.

Why We Recommend This Product


This is where the Katadyn Vario Water Filter truly shines. With its extremely savvy dual pumping mode, you now have the option of using a fast speed function of filtering 2 quarts per minute. A quart equals to almost a liter, so the fast mode is very useful in a pinch. The normal, longer life mode filters 1 quart per minute, which is still not bad.

We love the sheer versatility of the Katadyn Vario Water Filter. You need not replace the entire product in case of an unfortunate malfunction. You can replace each of the individual parts separately. For example, you can elect to replace the glass fiber filter or just opt for the activated charcoal. The former has a capacity of 500 gallons while the latter is not that long lasting. We recommend you think about your budget when deciding which to buy.

There is further an optional ceramic pre-filtration disc. This will extend the shelf life of your water filter significantly. As we said, the Katadyn Vario Water Filter is a hit due to its versatility and flexibility of choice.

One last thing to note that adds to the ease of use of the water filter is the fact that the adapter base can fit directly to the mouths of water bottles. Alternately, an output host can be used in order to fill larger containers or hydration bladders.


Priced $95, the Katadyn Vario Water Filter is an economical choice when considering its top-tier features. The most attractive feature being versatility, the replacement cost of the filters is in the hands of the user. You may choose to replace the glass fiber filter for less maintenance, OR you can opt for the activated charcoal for maintaining a budget.

Either way, the Katadyn Vario Water Filter is cost-effect by dint of its three-step filtration process. And if you really want to take it up a notch at the expense of some extra cost, then the ceramic pre-filtration disc will add to the quality.

Alternate Choices

With the title promising everything you could want out of a water filter, some of you may not be buying it (in both the sense of the word). You may think that the Katadyn Vario Water Filter does not have as premium of a quality like bigger capacity that you were expecting. OR, you may have been expecting a cheaper model.

Katadyn knows all of that, and that’s why it has manufactured a wide spectrum of choices fit for all potential buyers. For example, take a look at the following products:

Katadyn Mini Ceramic Microfilter

Being the lightest and most compact Ketadyn water filter, you might wonder how good it can be. Think again. This water filter comes with the following:

  • a ceramic microfilter catridge
  • an input hose with prefilter
  • an output hose
  • a cleaning pad
  • a measuring gauge
  • a Deluxe carrying bag
  • refillable activated Carbon core

This mini water filter takes care of 99.9999% bacteria, sediments and also makes water drinkable and tasty. So, put your mind at ease about a mini filter not performing well enough. We highly recommend this product for those on a budget and solo hikers, adventurers.

Katadyn KFT Expedition Filter

From the smallest to the biggest, this product will show you the two opposite ends of the spectrum that Katadyn has in store. This water filter is of industrial quality, fit for professional outdoor companies and international rescue missions.

Costing over a thousand dollars, this water filter is not for everyone indeed. However, it is for people who want the very best, exactly the way it was designed to be. Capable of filtering 26,000 gallons before needing replacement, it is the most reliable water filter ever. What’s more, its replacement filter costs just about $200, which is a really good deal considering the fact that replacement of other water filters cost half as much as the filters themselves.

Katadyn Hiker Pro Transparent Water Filter

From the two ends of the spectrum to the our personal favorite – let us introduce you to the Katadyn Hiker Pro. As its name reveals, it caters to pro hikers. That means superior quality. If you thought water filters can’t hold a candle to water purifiers, think again. This water filter pushes the boundaries of what a water filter can do – its superior features cut down bacteria and protozoan cysts down to 0.2 microns.

Katadyn Hiker Pro Transparent Water Filter, Lightweight, Compact Design for Personal or Small Group...
  • Proven protection against bacteria and protozoan cysts down to 0.2 micron with pleated glass-fiber filter media
  • Activated carbon in the core of the filter improves the taste and reduces chemicals in your drinking water

Did you think that since the features are so premium, the water filter will be heavy? Absolutely not! Weighing at just 11 oz., it is ultra light. And if you think that a few oz. of difference is nothing, ask professional hikers and you will change your mind. What’s more, this Katadyn water filter is transparent, so you can see for yourself how pure and refreshing the filtered water looks! Oh, and you get to see the process of filtration as well. Fun, huh?
