The main advantages of the Aquafor Wagon filter are affordability, low cost and a good degree of purification, immediately lost against its main drawback. In field conditions, it only works with a PET bottle or its equivalent if it has the same throat with a similar thread as a PET bottle.
Non-standard and alternative application of a field filter Aquaphor Universal for water purification in the field.
To use the Aquafor Universal wagon filter in the field, this was not entirely convenient. I had to constantly carry with me some PET bottle or look for it on the spot. This greatly limited the applicability of this filter. The principle of operation of the Aquaphor Universal filter is based on the creation of pressure, under the influence of which water enters the filter element, is filtered and then falls into the desired container. The same principle was used to make this filter more versatile..

But it’s not always that we will have, within the limits of accessibility, some kind of pond or source of water into which you can immerse the filter rubber bulb, as shown in the video. It may turn out that in addition to the dirty water from a deep road rut or shallow swamp, nothing will happen. It’s okay, then we use any container in which you can draw this water and then immerse the pear in it. For example, if available, a garbage bag, a bag for freezing, a cap, a baseball cap, etc..

As a big drawback, with this method of filtration, I would like to note the significantly reduced filter performance of Aquaphor Universal. Unfortunately, it is not more than 100-150 ml of water per minute.
