Мембранный Фильтр. Новый способ восстановления. Без затрат.

Membrane filter. A new restoration method. No expense spared. This is my own development, which utilizes the principle of water expansion upon freezing, which causes harmful salt deposits to peel off from the membrane surface. Subsequently, a method of decomposing and removing the salt breakdown products is used, using a highly acidic liquid supplied under normal atmospheric pressure. This method is completely effective! It will save you both the filter and money. Good luck to everyone!
