Purification methods can be divided up into settling of suspended matter, physical or chemical treatment of colloids and biological treatment.

There are several water filters in that price range, here are a few:

Anaerobic water treatment meant that bacteria which are not oxygen dependent are converting contaminations in the water. Anaerobic bacteria can only convert when oxygen levels are very low, because they use other sorts of substances to perform chemical conversion. Anaerobic bacteria don't only develop carbon dioxide and water during conversion, but also methane gas.

Katadyn water filters are great. Both my husband and I use ours when we go camping. I will send you a video link that explains how they work.

The water purification process in not vey one sided. The purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water.

I can tell you that they are both considered to be very good water filters. Due to my personal experience with the both of them I advise you to pick the activated carbon filter, it is a bit more expensive than the sediment but I last more time and live much less scale in your water.

Bacteria and other microorganisms are removed from water through disinfection. This means that certain substances are added to the water in order to kill the bacteria, these are called biocides. Sometimes disinfection can also be done with UV-light.

Water disinfection is a purification process that kills or removes biological contaminations from water sources. In some cases, additional contaminations may be added to the water by the disinfection process.

Water purification means freeing water from any kind of impurity it contains, such as microorganisms or contaminants.

If you do the distillation process exactly right it is almost 100 percent safe to drink the distillated water. Although it is very difficult to do it right and the distillation process is very slow and consumes a lot of energy therefore very expensive.
