I agree - the numbers simply don't add up.
The actual figures, with 1 lifting balloon capable of lifting 20kg every 250m, to a height of 1000m are (in grammes):
mass of netting per sq m = 20,000g / 1000m / 250m = 0.08g per sq m.
That would be an incredible material! If it could stop a mosquito, or even support its own weight it would be nothing short of a miracle. Even kitchen / food storage 'clingfilm' has a mass about 15 times greater per sq m (1.2g for clingfilm vs 0.08g per sq m for Russia's claimed new miracle material). I doubt it would be sneeze-resistant from 10 metres away! It must definitely be made from that magical, mythical new Engineering material, recently invented by the Russians, known as Unobtainium.
It is extraordinary that the propaganda machine of Russia continues to spout such utter garbage, hoping it will be believed. This proposed defence device is supported purely by a load of hot air!
