Cons

Con
Expensive cartridge replacement

The cartridge filter is good enough to filter up to 1500 liters of water, after that it needs to be replaced. The replacement filter is on the expensive side, costing around 50 dollars.

Con
No covers for the tubing

There are no covers included for the connecting points so you have to pay extra attention keeping them clean when the system is stored.

Con
Doesn’t filter out viruses

The hollow fiber filters out bacteria and protozoa as large as 0.2 microns but doesn’t filter out viruses. It shouldn’t be a problem in North America, but be careful when using it in parts of the world where the water can be contaminated.

Con
You need to work for clean water

The filtration system isn’t driven by gravity or any electronics instead you need to manually pump to get the water filtrated. This can be very time consuming and tiresome if you need to filter large amounts of water.
