A portable water filter developed by Kalashnikov Concern has been tested in the SVO zone

A portable water filter has been tested in the SVO area. It was developed by Kalashnikov Concern JSC. The length of the product is 150 mm, the diameter is about 30 mm, the weight is 60 g, that is, the dimensions are such that it will easily fit into a pocket, told Izvestia in JSC Concern Kalashnikov.

The product's resource is about 20 thousand liters, which is comparable to the supply of fresh water on a diesel submarine, which is several times higher than the filters currently available on the market. The capacity is at least 12 liters/hour.

Externally, the product looks like a plastic pencil case with a silicone hose. There are water purifying elements inside it. The first barrier is a coarse filter to remove large particles of contamination, it is coated with silver to impart bactericidal properties. The main filter consists of track membranes with pores measuring 0.4 microns each. They let water through, but retain pathogenic bacteria.

"The filter itself can be thrown into a puddle and immediately start drinking water. To do this, he is equipped with a special hose with a nipple. If necessary, the filter can be screwed directly onto a plastic bottle with dirty water — it is provided with a thread of the required diameter. By pressing on the tank, we will create pressure, which allows us to filter a larger volume of water per unit of time — this increases its productivity," Vasily Khudoleev, director of the medical research division at Kalashnikov Concern, told Izvestia.

In the free zone, the products have confirmed their characteristics and in the future may be included in the basic set of a serviceman, he noted.

The military, who used the filter in their area, asked for improvements, for example, to make a pouch so that the filter could be worn on a belt, Khudoleev said.
